Paradise Lost?
The Coastal Prairie of
Louisiana and Texas
2 3
Coastal prairie is a
native grassland found
along the coast of Texas
and Louisiana. Over nine
million acres of prairie
once existed as a grassland
paradise for Native
Americans and early
settlers. Today less than
1% remains as a refuge
for rare and endangered
birds, mammals, reptiles,
insects and plants. Is
“Paradise Lost?” Private
groups, conservation
organizations, and
government agencies are
working together to protect
and restore this “critically
imperiled” ecosystem.
They need your help and
support if this effort is to
succeed.

wildlife refuges.
History
The Coastal Prairie is located along
the western gulf coast of the United
States, in southwest Louisiana and
southeast Texas, just inland from the
coastal marsh (see map). This Coastal
Prairie is a tallgrass prairie similar in
many ways to the tallgrass prairie of
the midwestern United States. It is
estimated that, in pre-settlement
times, there were nine million acres
of Coastal Prairie, with
2.5 million acres in
Louisiana, and 6.5 million acres in
Texas. Today, substantially less than
one percent of the Coastal Prairie
remains with remnants totaling less
than 100 acres in Louisiana and less
than 65,000 acres in Texas. While
much of the
former prairie
has been
converted to
pasture for
cattle grazing,
the majority has
been altered for
growing rice,
sugarcane,
forage, and
grain crops. In Louisiana, most of the
prairie’s few remaining remnants are
found on narrow strips of land along
railroad tracks. A larger amount
remains in Texas because it was used
for cattle production and never
plowed. Many species, however, have
been lost through overgrazing.

The “Cajun Prairie” of Louisiana
The portion of Coastal Prairie found in southwest
Louisiana is often called the “Cajun Prairie”
because it was settled in the early nineteenth
century by exiled Acadian settlers. As of 1999, less
than 100 acres remain of the 2.5 million acres that
once dominated this area, making it one of our most
endangered ecosystems. Most of the few remaining
remnants of prairie in Louisiana are found on
narrow strips of land along railroad tracks. Despite
the small size of these remnants, most contain a high
diversity of native tallgrass prairie flora.
What makes Coastal Prairie a prairie?
The Coastal Prairie can be likened to
the central and northern “tallgrass
prairie.” Many wildflowers common
to the Midwestern prairies such as
button snakeroot, compass plant,
Kansas gayfeather, and black-eyed
susan are also found in Coastal
Prairie. In those remnants that still
exist in Louisiana, switchgrass, little
bluestem, big bluestem, and
Indiangrass dominate just as they do
in the Midwest. Because of the
region’s high rainfall, and the fact
that Coastal Prairie gradually turns
into coastal marsh in Louisiana,
switchgrass is more common than in
Midwestern prairies. In contrast,
remnants of Coastal Prairie in Texas
are dominated by little bluestem,
brown-seed paspalum, and
Indiangrass. Common wildflowers
found here are the prairie coneflower,
Texas coneflower, white heath aster
and yellow-puff.
Coastal Prairie differs from that
found in the Midwest because plant
species like sweet golden rod, red
milkweed, and the grasses slender
bluestem and brown-seed paspalum
are found here. Coastal Prairie also
provides habitat for the Attwater’s
prairie chicken, a relative of the
extinct heath hen once found in the
Midwest.
Factors that contribute to the
establishment and maintenance of
prairie are soil type, fire, rainfall, and
grazing. Drought, fire, and
competition from adapted plant
species combine to prevent the
establishment of woody plants and
maintain a grass-dominated
ecosystem.
Many prairie species depend on fire
for seed production because it
removes accumulated plant litter and
satisfies seed dormancy needs.
Drought occurs in areas of low
rainfall and heavy clay soils hold
water making it unavailable to plants.
Plants can also experience drought-like
stress as a result of root
restriction caused by a 8-12" deep
hard pan layer in some soils that
roots cannot penetrate. Grazing
(historically bison and elk and now
cattle) affects prairie vegetation in
various ways. While it helps seeds to
germinate by removing their seed

coat during digestion, it also stresses
grazed plants and creates
disturbances that allow other plants
to establish. Smaller grazers such as
grasshoppers and other plant-eating
insects often concentrate on a single
plant species, leaving its neighbors
untouched, therefore giving them an
advantage over their competitors.
Natural prairie abounds with long-lived
perennials which form a dense
“sod” or mat of intertwined roots.
Disturbances to this dense mass are
rapidly filled in by growth from
surrounding plants. With the
exception of partridge pea, false-foxgloves
and a few others, annuals
are rare in undisturbed prairie sod.
Plants
Coastal prairie vegetation consists
mostly of grasses overlain by a
diverse variety of wildflowers and
other plants. Its wildflowers are often
found in patches creating a “flower
garden” in the green sea of grass.
Nearly 1,000 plant species have been
identified in Coastal Prairie and
almost all are perennials with
underground structures (not all these
structures are roots) like rhizomes,
tubers, or crowns. These underground
structures have a variety of functions,
one of which is to ensure survival after
fire. The underground portion of
Coastal Prairie plants may be up to
three times the size of the
aboveground part.
Coastal Prairie flowers bloom in a
vivid range of colors from the green
of the green flowered milkweed and
nose burn; to the white of flowering
spurge and button snakeroot; to the
yellow of partridge pea and compass
plant; to the blue of blue waterleaf
and Sampson’s snakeroot; to the pink
of false dragonhead and sensitive
briar; to the
purple of
gayfeathers and
ironweed; and to
the red of the
red milkweed
and winecup.
Coastal Prairie
wildflowers are
a diverse group
with many
species
belonging to the
sunflower,
legume, and
mint families.
Native
Americans and
European
settlers on the
Coastal Prairie
used plants for
foods, spices,
dyes, textiles,
and medicines.
Some of the more spectacular plants
in Coastal Prairie include: blazing
stars (with up to three foot spikes of
purple flowers); compass plants (with
leaves pointing east and west); button
snakeroot (an important nectar
source for many insects); sweet
golden rod (with a liquorice odor and
that can be used to make a tea); false
indigos (yellow or white flowered
species, whose flowers were used by
early settlers to dye Easter eggs);
and butterfly weed (with bright
orange flowers favored by
butterflies).

What’s at risk?
Wildflowers and grasses once
covered the Coastal Prairie region,
along with birds, butterflies, and
other insects. In earlier times it was
home to herds of bison and
pronghorn antelope, and red wolves
roamed among the riverine forests
that crisscrossed the area. Today, the
bison, antelope, and red wolves have
disappeared, and this ecosystem is
listed as “critically imperiled” by
major conservation organizations.
No one knows how many Coastal
Prairie species have followed the
prairie vole and the Louisiana Indian
paintbrush to extinction, but it is
certain that many other species are
now quite rare. The black-lace cactus
and Texas prairie dawn-flower are the
Animals
Coastal Prairie, and its adjacent
marsh habitat, provided immense
spaces for waterfowl and thousands of
other forms of wildlife. Even in its
altered state, Coastal Prairie
routinely hosts more red-tailed hawk,
northern harrier, white ibis, and
white-faced ibis than any other region
in the United States. Waterfowl,
sandpipers, and other shorebirds are
abundant during the fall, winter, and
spring months, paralleling and often
surpassing other regions with
longstanding traditions as crucial
stopover areas for these species.
Many rare European species such as
northern wheatear, black-tailed
godwit, curlew sandpiper, and ruff
have also been observed routinely.
Prairie flowers and insects naturally go
together. Native insects need native
plants as food, and many prairie plants
provide plentiful and continuous
supplies of nectar. Prairie also provides
habitat with relatively little insecticide
residue. The result is unique insect
diversity including butterflies,
dragonflies, and numerous kinds of
bees, wasps, ants, grasshoppers,
beetles, and preying mantis. This
plethora of insects provides a food
source for many animals enhancing
the habitat value of Coastal Prairie.
The most conspicuous prairie insects
are the butterflies and skippers with
more than 100 species found in
Louisiana’s prairie alone. The gulf
fritillary, also known as the passion-vine
butterfly, is the most common
butterfly species found in Coastal
Prairie. Monarchs, whose larvae
depend on the many milkweeds found
in Coastal Prairie, are frequent
visitors. More than 100 different
species of dragonfly eat mosquitoes
and other insects as they dart and bob
over the prairie. The prairie forceptail
is a unique dragonfly in the Cajun
Prairie as it is seen nowhere else.

Milkweed Butterflies
The milkweed butterflies are a
family of mostly tropical butterflies
that includes the monarch and the
queen. Monarch butterflies cannot
withstand freezing temperatures, so
they migrate south for winter, flying
several thousand miles. The larvae
of these North American species
feed on milkweeds, incorporating
toxic substances into their bodies
and making them distasteful to
predators.Twelve species of
milkweed occur in Coastal Prairie,
making the area an important
element in the migration flyway of
monarchs. Some monarchs winter
on the gulf coast, depending on the
great variety of Coastal Prairie
wildflowers for nectar.

Chinese tallow
The suppression of fire allows
remnants to become overgrown with
native shrubs like eastern baccharis
and wax myrtle. Another able
invader, and a primary threat to
Coastal Prairie, is the Chinese tallow
tree. Chinese tallow and other exotic
plants invade Coastal Prairie, often
becoming the focus of land managers.
While fire is an important tool in the
control of these exotic plants,
herbicides are also used. The impact
of herbicide used for control of
prairie invaders and weeds on
adjacent croplands has not yet been
fully explored. There are other exotic
plants that are fire and herbicide
tolerant and while they have not yet
arrived in Coastal Prairie may
present even
greater
problems in
the future.
The current
absence of
big bluestem,
Indiangrass,
and some
wildflowers
in many
Texas
prairies may
be due to
overgrazing
by cattle. Palatable native grasses
such as big bluestem, Indiangrass,
and eastern gamagrass cannot
tolerate the close grazing of cattle
but are adapted to the occasional,
fast moving, tip nipping of bison.
Foreign species, such as vaseygrass,
from South America, and
johnsongrass, from the Mediterranean,
are adapted to cattle grazing and
flourish in overgrazed prairie. While
haying and rotational grazing are
important tools of prairie
managment, overgrazing can
decrease diversity and impact the
effectiveness of fire.
only Coastal Prairie plant species on
the U.S. Fish and Wildlife Service’s
endangered species list. However,
more than a dozen plant species are
listed as imperiled or critically
imperiled, including the wild coco,
Texas windmill grass, coastal
gayfeather, and Correll’s false
dragonhead. Another 15 plant species
are listed as rare to very rare including
Texas coneflower, fringed sneezeweed,
Silveus dropseed, southwestern
bedstraw, and lemon beebalm.
In addition to plants, the Coastal
Prairie is home to the federally-endangered
Attwater’s prairie
chicken (North America’s most
endangered bird) and is the exclusive
wintering ground of the
federally-endangered
whooping crane. Other
residents such as the gulf
coast hognosed skunk and
the Cagle’s map turtle
are also critically
imperiled. A number of
rare migratory grassland
birds depend on coastal
grasslands including
Bachman’s, Texas olive
and Henslow’s sparrows
and the loggerhead
shrike.
Threats
Development poses the greatest risk
to what remains of Coastal Prairie.
Most remnants are privately owned
with only a small percentage
preserved on government land. The
largest and most pristine remnants
in Texas are hay meadows, and they
are in danger of development or
conversion to other kinds of
agriculture. Remnants along
railroads make up much of what
remains in Louisiana and are
currently being destroyed when
adjacent highways are widened or
railroad beds are graded or sprayed
with pesticides.

The Coastal Prairie Conservation
Initiative is a partnership between
the U.S. Fish and Wildlife Service,
the U.S. Department of Agriculture’s
Natural Resources Conservation
Service, local soil and water
conservation districts, and private
landowners along the middle and
upper gulf coast
region of Texas. The
goals of this initiative
are to conserve and
restore the Coastal
Prairie ecosystem,
reintroduce captive-bred
Attwater’s
prairie chickens on
private lands, and
provide private
landowners with
incentives directed at
Coastal Prairie
conservation.
Restoration methods
vary between
geographical areas
and individual
restorationists, and
success varies from year to year.
Planting a restoration involves:
1. site preparation by herbicide,
solarization, and/or tillage;
2. planting by haying, seeding,
hydromulching, sodding,
plugging, and/or reintroduction;
and
3. management by mowing,
irrigation, grazing, and/or
burning.
Fall and winter are generally the best
times for planting. Seeds can be
purchased commercially but are
sometimes hard to find. If seeds are
collected from wild populations it is
best to collect from plants in the
vicinity of your restoration. These
Restoration
Even if every acre of Coastal Prairie
now in existence were preserved for
future generations, we would continue
to lose species to extinction. Plants
and animals need large areas of habitat
for survival, so if
future generations are
to enjoy the
biodiversity found in
Coastal Prairie, more
area must be restored.
Enthusiasm for
restoration of Coastal
Prairie is growing
thanks to the efforts of
pioneers like Drs.
Charles Allen and
Malcolm Vidrine who
in 1988 succeeded in
restoring a prairie in Eunice,
Louisiana. A number of private groups
and conservation organizations
exchange information, provide
education, work to preserve remnants,
and assist restoration efforts while
government agencies assist private
land owners with incentive programs.
Scientists at the U.S. Geological
Survey’s National Wetlands Research
Center are conducting experiments
relevant to prairie restoration and
management and are developing
methods to disseminate this information.
The U.S. Fish and Wildlife Service
lists restoration of Coastal Prairie
as one of its top priorities in the gulf
coast area. National wildlife refuges
including Anahuac, Aransas,
Attwater, Brazoria, Cameron
Prairie, Lacassine and Sabine are
restoring and managing prairie on
federal lands. Lacassine NWR in
Louisiana has embarked on several
Coastal Prairie restorations
including 327 acres called the
Duralde Prairie. Brazoria National
Wildlife Refuge in Texas has
undertaken to restore more than
5,000 acres of overgrazed prairie by
limiting cattle grazing, conducting

It is most common to burn when
plants are dormant, but an occasional
burn during the growing season
enhances diversity. Where fire is not
an option, the restoration may be
mowed or hayed (mowing and haying
are very different — hay is not
removed after mowing), but this may
affect the species that survive long
term. Weeds such as Chinese tallow
trees may have to be sprayed with
herbicide or physically removed,
especially from wet spots where fire
does a poor job of control. It will take
several years before a Coastal Prairie
patch begins to mature, but when it
does, most weedy exotics will be
excluded naturally.
The Coastal Prairie is a unique and
vital part of the biosphere that has
almost vanished within the last 100
years. Much has been lost both in
terms of land coverage and native
species, and what remains is in need of
protection and rehabilitation. Because
so little remains, the future of Coastal
Prairie depends on restoration.
Americans can help in this effort to
protect and restore Coastal Prairie by
supporting or
participating in
restoration
efforts. Even a
small backyard
prairie garden
(12' x 12')
provides a piece
of this native
ecosystem.
Thousands of
such gardens dot
the midwestern
countryside,
providing a

and birds, and an

plants are adapted to local conditions
and their gene pools should be
preserved. Restorationists do not
agree on how far from a site seeds
may be collected, and distances
range from 50 to 250 miles. Most
restorationists use 100 miles as a
rule of thumb,
and that distance
can be stretched
east or west if
no other seeds
are available.
Individuals or
organizations
interested in
restoration
should thoroughly
explore the
options. Several books, websites, and
experts are available to assist
restorationists, and some are listed at
the back of this brochure.
Management
Restorationists are often discouraged
when the first few years after a
restoration has been implemented,
aggressive annual weeds dominate
the site. However, they shouldn’t
despair for perennials will eventually
displace the weedy annuals. Experts
don’t recommend the use of fertilizer
because it will often give weedy
annuals an advantage.
Burning is the natural mechanism by
which prairie renews itself. Fire
prevents woody plants from
establishing, stimulates seed
germination, replenishes nutrients,
and allows light to reach young
leaves. Winter burning after the first
year speeds the change from an
annual community to one dominated
by perennial plants. Restorations can
be burned every one to three years
based on available fuel and
management objectives. Historically,
prairie fires occurred in the summer
as a result of lightning strikes.

| Transcript | U.S. Fish & Wildlife Service U.S. Geological Survey Paradise Lost? The Coastal Prairie of Louisiana and Texas 2 3 Coastal prairie is a native grassland found along the coast of Texas and Louisiana. Over nine million acres of prairie once existed as a grassland paradise for Native Americans and early settlers. Today less than 1% remains as a refuge for rare and endangered birds, mammals, reptiles, insects and plants. Is “Paradise Lost?” Private groups, conservation organizations, and government agencies are working together to protect and restore this “critically imperiled” ecosystem. They need your help and support if this effort is to succeed. Historical range of Coastal Prairie. Stars represent national wildlife refuges. History The Coastal Prairie is located along the western gulf coast of the United States, in southwest Louisiana and southeast Texas, just inland from the coastal marsh (see map). This Coastal Prairie is a tallgrass prairie similar in many ways to the tallgrass prairie of the midwestern United States. It is estimated that, in pre-settlement times, there were nine million acres of Coastal Prairie, with 2.5 million acres in Louisiana, and 6.5 million acres in Texas. Today, substantially less than one percent of the Coastal Prairie remains with remnants totaling less than 100 acres in Louisiana and less than 65,000 acres in Texas. While much of the former prairie has been converted to pasture for cattle grazing, the majority has been altered for growing rice, sugarcane, forage, and grain crops. In Louisiana, most of the prairie’s few remaining remnants are found on narrow strips of land along railroad tracks. A larger amount remains in Texas because it was used for cattle production and never plowed. Many species, however, have been lost through overgrazing. Coastal Prairie railroad remnant in July 4 5 The “Cajun Prairie” of Louisiana The portion of Coastal Prairie found in southwest Louisiana is often called the “Cajun Prairie” because it was settled in the early nineteenth century by exiled Acadian settlers. As of 1999, less than 100 acres remain of the 2.5 million acres that once dominated this area, making it one of our most endangered ecosystems. Most of the few remaining remnants of prairie in Louisiana are found on narrow strips of land along railroad tracks. Despite the small size of these remnants, most contain a high diversity of native tallgrass prairie flora. What makes Coastal Prairie a prairie? The Coastal Prairie can be likened to the central and northern “tallgrass prairie.” Many wildflowers common to the Midwestern prairies such as button snakeroot, compass plant, Kansas gayfeather, and black-eyed susan are also found in Coastal Prairie. In those remnants that still exist in Louisiana, switchgrass, little bluestem, big bluestem, and Indiangrass dominate just as they do in the Midwest. Because of the region’s high rainfall, and the fact that Coastal Prairie gradually turns into coastal marsh in Louisiana, switchgrass is more common than in Midwestern prairies. In contrast, remnants of Coastal Prairie in Texas are dominated by little bluestem, brown-seed paspalum, and Indiangrass. Common wildflowers found here are the prairie coneflower, Texas coneflower, white heath aster and yellow-puff. Coastal Prairie differs from that found in the Midwest because plant species like sweet golden rod, red milkweed, and the grasses slender bluestem and brown-seed paspalum are found here. Coastal Prairie also provides habitat for the Attwater’s prairie chicken, a relative of the extinct heath hen once found in the Midwest. Factors that contribute to the establishment and maintenance of prairie are soil type, fire, rainfall, and grazing. Drought, fire, and competition from adapted plant species combine to prevent the establishment of woody plants and maintain a grass-dominated ecosystem. Many prairie species depend on fire for seed production because it removes accumulated plant litter and satisfies seed dormancy needs. Drought occurs in areas of low rainfall and heavy clay soils hold water making it unavailable to plants. Plants can also experience drought-like stress as a result of root restriction caused by a 8-12" deep hard pan layer in some soils that roots cannot penetrate. Grazing (historically bison and elk and now cattle) affects prairie vegetation in various ways. While it helps seeds to germinate by removing their seed Attwater’s prairie chicken Rejuvenating prairie with winter fire Grasshopper foraging on prairie grass Cajun prairie along railroad right-of-way in May 6 7 Grasses and grasslike plants of the Coastal Prairie little bluestem big bluestem longspike tridens bushy bluestem falling beakrush gaping panicum gulf cordgrass knotroot bristlegrass pinewoods dropseed silver bluestem split-beard bluestem switchgrass Indiangrass Eastern gamagrass brown-seed paspalum Florida paspalum thin paspalum purple silkyscale Texas wintergrass toothache grass Carolina’s whipgrass Vahl’s hairy fimbry white-top sedge yellow-eyed-grass 8 9 coat during digestion, it also stresses grazed plants and creates disturbances that allow other plants to establish. Smaller grazers such as grasshoppers and other plant-eating insects often concentrate on a single plant species, leaving its neighbors untouched, therefore giving them an advantage over their competitors. Natural prairie abounds with long-lived perennials which form a dense “sod” or mat of intertwined roots. Disturbances to this dense mass are rapidly filled in by growth from surrounding plants. With the exception of partridge pea, false-foxgloves and a few others, annuals are rare in undisturbed prairie sod. Plants Coastal prairie vegetation consists mostly of grasses overlain by a diverse variety of wildflowers and other plants. Its wildflowers are often found in patches creating a “flower garden” in the green sea of grass. Nearly 1,000 plant species have been identified in Coastal Prairie and almost all are perennials with underground structures (not all these structures are roots) like rhizomes, tubers, or crowns. These underground structures have a variety of functions, one of which is to ensure survival after fire. The underground portion of Coastal Prairie plants may be up to three times the size of the aboveground part. Coastal Prairie flowers bloom in a vivid range of colors from the green of the green flowered milkweed and nose burn; to the white of flowering spurge and button snakeroot; to the yellow of partridge pea and compass plant; to the blue of blue waterleaf and Sampson’s snakeroot; to the pink of false dragonhead and sensitive briar; to the purple of gayfeathers and ironweed; and to the red of the red milkweed and winecup. Coastal Prairie wildflowers are a diverse group with many species belonging to the sunflower, legume, and mint families. Native Americans and European settlers on the Coastal Prairie used plants for foods, spices, dyes, textiles, and medicines. Some of the more spectacular plants in Coastal Prairie include: blazing stars (with up to three foot spikes of purple flowers); compass plants (with leaves pointing east and west); button snakeroot (an important nectar source for many insects); sweet golden rod (with a liquorice odor and that can be used to make a tea); false indigos (yellow or white flowered species, whose flowers were used by early settlers to dye Easter eggs); and butterfly weed (with bright orange flowers favored by butterflies).

Wildflowers and grasses once covered the Coastal Prairie region, along with birds, butterflies, and other insects. In earlier times it was home to herds of bison and pronghorn antelope, and red wolves roamed among the riverine forests that crisscrossed the area. Today, the bison, antelope, and red wolves have disappeared, and this ecosystem is listed as “critically imperiled” by major conservation organizations. No one knows how many Coastal Prairie species have followed the prairie vole and the Louisiana Indian paintbrush to extinction, but it is certain that many other species are now quite rare. The black-lace cactus and Texas prairie dawn-flower are the Animals Coastal Prairie, and its adjacent marsh habitat, provided immense spaces for waterfowl and thousands of other forms of wildlife. Even in its altered state, Coastal Prairie routinely hosts more red-tailed hawk, northern harrier, white ibis, and white-faced ibis than any other region in the United States. Waterfowl, sandpipers, and other shorebirds are abundant during the fall, winter, and spring months, paralleling and often surpassing other regions with longstanding traditions as crucial stopover areas for these species. Many rare European species such as northern wheatear, black-tailed godwit, curlew sandpiper, and ruff have also been observed routinely. Prairie flowers and insects naturally go together. Native insects need native plants as food, and many prairie plants provide plentiful and continuous supplies of nectar. Prairie also provides habitat with relatively little insecticide residue. The result is unique insect diversity including butterflies, dragonflies, and numerous kinds of bees, wasps, ants, grasshoppers, beetles, and preying mantis. This plethora of insects provides a food source for many animals enhancing the habitat value of Coastal Prairie. The most conspicuous prairie insects are the butterflies and skippers with more than 100 species found in Louisiana’s prairie alone. The gulf fritillary, also known as the passion-vine butterfly, is the most common butterfly species found in Coastal Prairie. Monarchs, whose larvae depend on the many milkweeds found in Coastal Prairie, are frequent visitors. More than 100 different species of dragonfly eat mosquitoes and other insects as they dart and bob over the prairie. The prairie forceptail is a unique dragonfly in the Cajun Prairie as it is seen nowhere else. white ibis red-tailed hawks preying mantis hummingbird on ashy sunflower Milkweed Butterflies The milkweed butterflies are a family of mostly tropical butterflies that includes the monarch and the queen. Monarch butterflies cannot withstand freezing temperatures, so they migrate south for winter, flying several thousand miles. The larvae of these North American species feed on milkweeds, incorporating toxic substances into their bodies and making them distasteful to predators.Twelve species of milkweed occur in Coastal Prairie, making the area an important element in the migration flyway of monarchs. Some monarchs winter on the gulf coast, depending on the great variety of Coastal Prairie wildflowers for nectar. Illustrated at left are the stages of metamorphosis of a monarch butterfly: 1. the egg, 2. the caterpillar, 3. the pupa or chrysalis, and 4. the adult butterfly. 1 2 3 4 22 23 black swallowtail cloudless sulphur tiger swallowtail, female gorgone crescent tiger swallowtail, male pipevine swallowtail red admiral red spotted purple spring azure spicebush swallowtail zebra longwing buckeye butterfly gulf fritillary, female zebra swallowtail goatweed hackberry pearl crescent gulf fritillary, male queen varigated fritillary question mark viceroy wood nymph gray hairstreak Butterflies of the Coastal Prairie 24 25 Chinese tallow The suppression of fire allows remnants to become overgrown with native shrubs like eastern baccharis and wax myrtle. Another able invader, and a primary threat to Coastal Prairie, is the Chinese tallow tree. Chinese tallow and other exotic plants invade Coastal Prairie, often becoming the focus of land managers. While fire is an important tool in the control of these exotic plants, herbicides are also used. The impact of herbicide used for control of prairie invaders and weeds on adjacent croplands has not yet been fully explored. There are other exotic plants that are fire and herbicide tolerant and while they have not yet arrived in Coastal Prairie may present even greater problems in the future. The current absence of big bluestem, Indiangrass, and some wildflowers in many Texas prairies may be due to overgrazing by cattle. Palatable native grasses such as big bluestem, Indiangrass, and eastern gamagrass cannot tolerate the close grazing of cattle but are adapted to the occasional, fast moving, tip nipping of bison. Foreign species, such as vaseygrass, from South America, and johnsongrass, from the Mediterranean, are adapted to cattle grazing and flourish in overgrazed prairie. While haying and rotational grazing are important tools of prairie managment, overgrazing can decrease diversity and impact the effectiveness of fire. only Coastal Prairie plant species on the U.S. Fish and Wildlife Service’s endangered species list. However, more than a dozen plant species are listed as imperiled or critically imperiled, including the wild coco, Texas windmill grass, coastal gayfeather, and Correll’s false dragonhead. Another 15 plant species are listed as rare to very rare including Texas coneflower, fringed sneezeweed, Silveus dropseed, southwestern bedstraw, and lemon beebalm. In addition to plants, the Coastal Prairie is home to the federally-endangered Attwater’s prairie chicken (North America’s most endangered bird) and is the exclusive wintering ground of the federally-endangered whooping crane. Other residents such as the gulf coast hognosed skunk and the Cagle’s map turtle are also critically imperiled. A number of rare migratory grassland birds depend on coastal grasslands including Bachman’s, Texas olive and Henslow’s sparrows and the loggerhead shrike. Threats Development poses the greatest risk to what remains of Coastal Prairie. Most remnants are privately owned with only a small percentage preserved on government land. The largest and most pristine remnants in Texas are hay meadows, and they are in danger of development or conversion to other kinds of agriculture. Remnants along railroads make up much of what remains in Louisiana and are currently being destroyed when adjacent highways are widened or railroad beds are graded or sprayed with pesticides. wild coco American bison Henslow’s sparrow whooping crane 26 27 calico pennant black saddlebags blue dasher, female blue footed dancer citrine forktail, male common green darner, male common green darner, male common whitetail, female common whitetail, male eastern pondhawk, female ebony jewelwing prairie forceptail, familiar bluet female widow skimmer, female golden winged skimmer golden winged skimmer Halloween pennant, female prairie forceptail, male widow skimmer, male Needham’s skimmer painted skimmer Rambur’s forktail roseate skimmer, male varigated meadowhawk Dragonflies of the Coastal Prairie 28 29 prescribed burns, haying, and chemically controlling invasive plants. The Coastal Prairie Conservation Initiative is a partnership between the U.S. Fish and Wildlife Service, the U.S. Department of Agriculture’s Natural Resources Conservation Service, local soil and water conservation districts, and private landowners along the middle and upper gulf coast region of Texas. The goals of this initiative are to conserve and restore the Coastal Prairie ecosystem, reintroduce captive-bred Attwater’s prairie chickens on private lands, and provide private landowners with incentives directed at Coastal Prairie conservation. Restoration methods vary between geographical areas and individual restorationists, and success varies from year to year. Planting a restoration involves: 1. site preparation by herbicide, solarization, and/or tillage; 2. planting by haying, seeding, hydromulching, sodding, plugging, and/or reintroduction; and 3. management by mowing, irrigation, grazing, and/or burning. Fall and winter are generally the best times for planting. Seeds can be purchased commercially but are sometimes hard to find. If seeds are collected from wild populations it is best to collect from plants in the vicinity of your restoration. These Restoration Even if every acre of Coastal Prairie now in existence were preserved for future generations, we would continue to lose species to extinction. Plants and animals need large areas of habitat for survival, so if future generations are to enjoy the biodiversity found in Coastal Prairie, more area must be restored. Enthusiasm for restoration of Coastal Prairie is growing thanks to the efforts of pioneers like Drs. Charles Allen and Malcolm Vidrine who in 1988 succeeded in restoring a prairie in Eunice, Louisiana. A number of private groups and conservation organizations exchange information, provide education, work to preserve remnants, and assist restoration efforts while government agencies assist private land owners with incentive programs. Scientists at the U.S. Geological Survey’s National Wetlands Research Center are conducting experiments relevant to prairie restoration and management and are developing methods to disseminate this information. The U.S. Fish and Wildlife Service lists restoration of Coastal Prairie as one of its top priorities in the gulf coast area. National wildlife refuges including Anahuac, Aransas, Attwater, Brazoria, Cameron Prairie, Lacassine and Sabine are restoring and managing prairie on federal lands. Lacassine NWR in Louisiana has embarked on several Coastal Prairie restorations including 327 acres called the Duralde Prairie. Brazoria National Wildlife Refuge in Texas has undertaken to restore more than 5,000 acres of overgrazed prairie by limiting cattle grazing, conducting Sign at eleven-year-old restoration site.

It is most common to burn when plants are dormant, but an occasional burn during the growing season enhances diversity. Where fire is not an option, the restoration may be mowed or hayed (mowing and haying are very different — hay is not removed after mowing), but this may affect the species that survive long term. Weeds such as Chinese tallow trees may have to be sprayed with herbicide or physically removed, especially from wet spots where fire does a poor job of control. It will take several years before a Coastal Prairie patch begins to mature, but when it does, most weedy exotics will be excluded naturally. The Coastal Prairie is a unique and vital part of the biosphere that has almost vanished within the last 100 years. Much has been lost both in terms of land coverage and native species, and what remains is in need of protection and rehabilitation. Because so little remains, the future of Coastal Prairie depends on restoration. Americans can help in this effort to protect and restore Coastal Prairie by supporting or participating in restoration efforts. Even a small backyard prairie garden (12' x 12') provides a piece of this native ecosystem. Thousands of such gardens dot the midwestern countryside, providing a refuge for native plants, insects, and birds, and an alternative, sustainable landscape. plants are adapted to local conditions and their gene pools should be preserved. Restorationists do not agree on how far from a site seeds may be collected, and distances range from 50 to 250 miles. Most restorationists use 100 miles as a rule of thumb, and that distance can be stretched east or west if no other seeds are available. Individuals or organizations interested in restoration should thoroughly explore the options. Several books, websites, and experts are available to assist restorationists, and some are listed at the back of this brochure. Management Restorationists are often discouraged when the first few years after a restoration has been implemented, aggressive annual weeds dominate the site. However, they shouldn’t despair for perennials will eventually displace the weedy annuals. Experts don’t recommend the use of fertilizer because it will often give weedy annuals an advantage. Burning is the natural mechanism by which prairie renews itself. Fire prevents woody plants from establishing, stimulates seed germination, replenishes nutrients, and allows light to reach young leaves. Winter burning after the first year speeds the change from an annual community to one dominated by perennial plants. Restorations can be burned every one to three years based on available fuel and management objectives. Historically, prairie fires occurred in the summer as a result of lightning strikes. Native Americans often burned Hay seeding Coastal Prairie at Lacassine National Wildlife Refuge.
