CHAPTER 4. SPECIES OF GREATEST CONSERVATION NEED

SPECIES OF GREATEST CONSERVATION NEED LA WAP—OCTOBER 2015

A. Species of Greatest Conservation Need

The primary focus of the Louisiana Wildlife Action Plan (WAP) is the recovery of

Species of Greatest Conservation Need (SGCN), those wildlife species in need of

conservation action within Louisiana. SGCN may be species for which population

declines have been documented or suspected, or species that may be subject to population

declines within the next 10 years. Other species are included because more data are

needed to accurately determine their status. The identification of SGCN is Element # 1 of

the Eight Required Elements for State WAPs. This Chapter also addresses Elements # 3

(Threats to SGCN, priority research and survey needs for SGCN) and # 4 (Description of

conservation actions necessary to conserve SGCN).

For details on the approach the Louisiana Department of Wildlife and Fisheries

(LDWF) used to revise the 2005 SGCN list during the 2015 revision, refer to Chapter 3

(Approach). For additional information on the 2005 approach, refer to Appendix B. This

Chapter contains the updated SGCN list for Louisiana, binned by taxonomic group. For a

complete list of SGCN in taxonomic order, see Appendix I. Within each taxonomic

group, the SGCN are divided into three tiers, with Tier I containing those species that are

most in need of immediate conservation action. For detailed information on the factors

and methodology used to determine these tiers, see Chapter 3. Research needs and

conservation actions that have been identified for Louisiana SGCN can be found in

Section C below. There are a total of 345 animal SGCN identified in this 2

iteration of

the Louisiana WAP, compared to 240 SGCN in the 2005 WAP. Ultimately, 25 SGCN

identified in the 2005 WAP were removed from the list, and 130 SGCN were added (for

details see the Summary of Changes). Almost half (61) of the newly identified SGCN are

invertebrates, reflecting a more consistent effort to address these species.

B. Threats, Research Needs, and Conservation Actions

Threats are described briefly for each taxonomic group below. These descriptions are

not comprehensive, but rather focus on major or specific threats to each group. Threats

were considered at the level of the 1

level threats provided by Salafsky et al. (2008).

Table 4.1 provides a summary of which threats are most pervasive in each group.

SPECIES OF GREATEST CONSERVATION NEED LA WAP—OCTOBER 2015

Table 4.1 1st Level Threats to SGCN

For more information on the threats posed by invasive species and climate change,

refer to Chapters 6 and 7 of this WAP, respectively.

Specific research needs and conservation actions are presented below for many

SGCN. However, these actions are not exhaustive and are not intended as the only

conservation priorities for these species.

C. SGCN by Taxonomic Group

1. Mollusks

North American freshwater mussels (Families Unionidae and Margaritiferidae) are

currently one of the world’s most imperiled taxonomic groups (Master et al. 2000).

Approximately 300 species of mussels are recognized in the United States (U.S.)

(Williams et al. 2008). The southeastern U.S. contains the greatest species diversity with

approximately 270 species, of which at least 64 species (~ 24% of the U.S. total) are

currently known to occur in Louisiana (Neves et al. 1997). Of these 64 species, 24

species are ranked as imperiled or critically imperiled in the state by the Louisiana

Natural Heritage Program (LNHP 2015). Federally-listed species include Rabbitsfoot

(USFWS 2013), Pink Mucket (USFWS 1976), Fat Pocketbook (USFWS 1989), Inflated

Heelsplitter (USFWS 1992), and Louisiana Pearlshell, the only mussel species endemic

to Louisiana (USFWS 1989b). In addition to 33 freshwater mussels, two snails, one

aquatic and one terrestrial, are included on the SGCN list. Finally, five marine mollusks

are included due to their dependence on highly restricted habitats within Louisiana. At

b. Threats to Mollusks

Sand and gravel mining operations pose a direct threat to some mussels, because such

activities may result in the degradation or complete loss of habitat. Construction of

infrastructure associated with transportation projects may directly impact mussel habitat

or lead to reduced water quality, as may the use of off-road vehicles (ORVs) near or

upstream of occurrences of SGCN. Modifications to streams, including the building and

operation of dams, construction of weirs, removal of snags and woody debris for

aesthetic or navigational purposes, and excessive removal of ground or surface water all

have the potential to decrease habitat quality and quantity. Additionally, the clearing of

riparian zones often leads to increased sedimentation, which increases turbidity and may

cause the extirpation of some mollusks. Another threat to water quality is through organic

enrichment and the concomitant alteration of the microbial community caused by Feral

Hog activity within streams, which may also result in the direct destruction of mussel

beds (Kaller et al. 2007). In addition to sediment, the input of household, industrial, and

agricultural effluents into streams poses a threat to freshwater mollusks. Sea level rise

(SLR) threatens freshwater mollusks in coastal streams due to increases in salinities and

threatens marine mollusks through the loss of seagrass beds associated with Barrier

Islands. If climate change results in decreased precipitation in our region, many

freshwater mollusks may be threatened, because reductions in rainfall could lead to a

reduction of in-stream flow.

c. Mollusk Research and Monitoring Needs

 Update historical occurrence records and obtain data on current status,

distribution, and abundance of all mussel SGCN (prioritized by S-rank),

particularly in the Red River, Bayou Bartholomew, Tensas River, and any areas

not surveyed within the last decade.

 Determine the host fish(es) of mussel SGCN.

techniques and initiate restocking efforts where needed.

 Work with parishes, the Louisiana Department of Transportation and

Development (DOTD), and other partners to install oversized culverts below

grade to allow passage of host fishes and, otherwise, to minimize impacts of

road/bridge/culvert construction and replacement on stream quality.

 Partner with parishes to encourage the retention of riparian buffers and discourage

stream clearing for storm water drainage.

 Work with timber companies to encourage designation of streamside management

zones (SMZs) within actively managed areas.

 Maintain in-stream flows at levels that will support populations of rare mussels

and host fishes.

 Conserve and restore the Chandeleur Islands and adjacent, shallow-water habitats

such as Marine Seagrass Beds.

 Restrict or outlaw the use of ORVs in streams, particularly the practice of “mud-

riding” through streambeds.

 Discourage the creation of weirs, dams, and reservoirs on streams and rivers

supporting mollusk SGCN.

 Work with partners to remove low-water sills on the Pearl River to benefit

mollusk SGCN.

2. Crustaceans

There are 338 crawfish species in the U.S., with the southeast being the world’s

hotspot for crawfish diversity (Taylor et al. 1996). Thirty-five crawfish species are known

to occur in Louisiana (Walls 2009). Twenty of these crawfish species are considered rare

and local, imperiled, or critically imperiled by LNHP (2015), including at least five

endemic or apparently endemic taxa: Teche Painted Crawfish, Calcasieu Painted

Crawfish, Ouachita Fencing Crawfish, Caddo Chimney Crawfish, and Calcasieu Creek

Crawfish. Population viability of many of these rare crawfish is threatened because of

their small ranges. Any habitat degradation severe enough to cause extirpation of these

species at a single site or a few sites could also lead to their extinction (Taylor et al.

1996). In addition to crawfish, four species of marine shrimp are included on the SGCN

list, primarily due to a lack of data for these species.

b. Threats to Crustaceans

Loss of habitat due to development or conversion of land for agriculture may threaten

some primary and secondary burrowing crawfishes, especially those that have restricted

distributions. The threats posed by sand and gravel mining, transportation infrastructure,

ORVs, stream modification, Feral Hogs, pollution, and climate change discussed in

“Threats to Mollusks” above also apply to many stream dwelling crustaceans. The

backfilling of ditches, although not a modification of a “natural” system, nonetheless

negatively impacts some crawfishes, because species that utilize ephemeral wetlands

sometimes are found associated with ecologically stable ditches. Furthermore, the

application of herbicides to control vegetation in such waterways may also threaten some

crawfishes by reducing cover and food availability or through direct mortality caused by

sensitivity to the herbicide (Walls 2009). An additional potential threat to crawfish SGCN

is the introduction of non-native crawfishes into Louisiana waterways.

c. Crustacean Research and Survey Needs

 Research life history strategies of all crawfish SGCN:

 Size/age at maturity, longevity, and survivorship.

 Habitat requirements and preferences, including microhabitat preferences.

SPECIES OF GREATEST CONSERVATION NEED LA WAP—OCTOBER 2015

 Population estimates and trends.

 Reproductive ecology [including fecundity and behavior of ovigerous (“in berry”)

females].

 Behavior, including migratory patterns, competition, and niche partitioning.

 Conduct drainage-wide surveys for all crawfish SGCN, including extensive

surveys for stream dwelling species beyond bridge crossings and historical

localities.

 Determine the appropriate in-stream characteristics that should be targeted during

stream restoration activities (e.g., dissolved oxygen levels, depth, flow, canopy

cover, submerged structure).

 Examine feasibility and efficacy of providing artificial cover in areas lacking

sufficient cover.

 Determine the lethal levels of common pollutants on crawfish.

 Monitor streams and other occurrences of rare crawfishes for the presence of non-

native crawfishes and emerging diseases.

 Develop standardized sampling protocols for monitoring known occurrences of

rare crawfishes to track population trends and improve understanding of

population dynamics.

 Evaluate current habitat threats and develop strategies to abate those threats.

 Investigate the impacts of Chinese Tallow on Ephemeral Pond dwelling rare

crawfishes.

d. Crustacean Conservation Actions

 Work with parishes and DOTD to minimize negative impacts of new stream

crossings and to mitigate negative impacts of existing stream crossings, including

promoting placement of submerged culverts.

 Work with landowners and the U.S. Department of Agriculture (USDA) Natural

Resource Conservation Service (NRCS) to encourage the retention of riparian

buffers.

 Ensure the presence of adequate cover (wood, vegetation, artificial debris) in

streams known to harbor rare crawfish.

 Maintain in-stream flows and water depths at levels that will support populations

of rare crawfish.

 Target degraded streams within the known range of one or more rare crawfish for

experimental restoration.

 Develop education/outreach materials concerning the unique native crawfishes of

Louisiana and the potential threats posed by non-native crawfishes and habitat

degradation.

 Protect and restore ephemeral wetlands for the benefit of primary and secondary

burrowing species.

 Encourage the retention of vegetation in known ditch occurrences of rare

crawfishes.

 Develop Habitat Suitability Indices (HSIs) for rare crawfishes.

3. Non-crustacean Arthropods

Unlike many more well-known taxa, there is no readily available number of species

of non-crustacean arthropods in Louisiana. Fifty-seven insects, one spider, and one

scorpion are included as SGCN. For the majority of these SGCN, the primary needs are

baseline data, because this group is the most poorly known of Louisiana’s fauna. To be

sure, the dearth of available subject-matter experts on these taxonomic groups resulted in

very limited expert input for these species. The list of butterfly SGCN from the 2005

WAP, along with the list of insects currently tracked by the LNHP, forms the backbone

of the non-crustacean arthropod list. Baseline studies of these taxa to address known data

gaps may lead to significant revision of this list for the next iteration of the WAP.

b. Threats to Non-crustacean Arthropods

An overarching stress for many terrestrial non-crustacean arthropod SGCN is habitat

destruction and alteration resulting from residential or commercial development, as well

as conversion of land to agricultural use. The indiscriminate use of insecticides,

particularly neonicotinoids, is also a threat to many insects, including butterflies,

skippers, and native bees. Finally, although the extent of impacts on native arthropods by

the Red Imported Fire Ant (RIFA) is unknown for many species, there is little doubt that

negative impacts are occurring; further investigation of those impacts and the persistence

of their effects on SGCN, both invertebrate and vertebrate, are warranted. For aquatic

insects, many of the same threats and stressors discussed under mollusks and crustaceans

pertain.

knowledge gaps for Louisiana and provide baseline data for future assessments.

4. Inland Fishes

Louisiana’s high diversity of inland fishes is due primarily to the complexity of

aquatic habitats, which range from small streams, bayous, oxbows and backwater areas,

large river systems, and estuarine areas of coastal Louisiana. At least 195 fish species

have been recorded from freshwater habitats in Louisiana. Thirty-one species of inland

fishes are considered rare and local, imperiled, or critically imperiled (LNHP 2015), and

39 species are considered SGCN. A management plan for the Paddlefish in Louisiana has

been developed by LDWF (Reed 1991). Federally-listed species for which recovery plans

have been developed include the Gulf Sturgeon (USFWS 1995) and Pallid Sturgeon

(USFWS 1993). The Pearl Darter has a historical range within the state but is now

considered extirpated (Suttkus et al. 1994).

b. Threats to Inland Fishes

As with crawfishes and aquatic insects, the threats posed by sand and gravel mining,

transportation infrastructure, ORVs, stream modification, Feral Hogs, pollution, and

climate change discussed under mollusks also apply to many inland fishes, because many

inland fish SGCN occupy similar habitats to those taxa. Invasive species, in addition to

aforementioned Feral Hogs, are also a major threat to many fish SGCN. Invasive species

negatively impact fish SGCN in several ways, including through habitat degradation,

increased competition for resources, and direct predation.

5. Marine Fishes

Marine fishes occur in a wide range of habitats, from low-salinity marshes and

estuaries to deep-water and open-ocean pelagic environments. Due to the productivity of

Louisiana’s coastal wetlands and bays, about 95% of its recreational and commercial

fishery production comes from species that are estuarine-dependent for some portion of

their life cycle. Less well known are population levels of the non-commercial species of

fish and invertebrates – the vast majority of the species present – that inhabit these

estuarine environments. Presence of these species is believed to be critical to the

functioning of the natural systems, and further surveys are needed to determine the status

of these populations. Surveys might also be designed to further the understanding of

ecological processes in these systems. The Smalltooth Sawfish is the only federally listed

marine fish in Louisiana, although no critical habitat has been designated at this time

(NMFS 2009). Eighteen species of marine fishes have been identified as SGCN during

the 2015 WAP revision. Many of these SGCN are very poorly known, due to a lack of

appropriate sampling effort. Therefore, for many of these species, the collection of

baseline data is high priority.

b. Threats to Marine Fishes

Many marine fishes utilize marshes at some point in their life, and coastal marshes

are often fragmented and subsequently degraded due to canals associated with energy

production and the service corridors related to those activities. Furthermore,

modifications to the natural hydrology of many systems have had negative impacts on

both the quantity and quality of marsh habitat. Invasive species threaten marine fishes on

several fronts, from marsh loss due to nutria herbivory to direct predation of smaller

native fishes by Lionfish. As with other aquatic SGCN, pollution from multiple sources is

a concern. Finally, SLR and tropical cyclones also threaten habitat that is critical to

marine species.

c. Marine Fishes Research and Survey Needs

6. Amphibians and Reptiles

One hundred forty species of amphibians and reptiles occur in Louisiana and its

adjacent waters (Dundee and Rossman 1989, LNHP 2015). However, Louisiana is unique

among high-diversity states in that it has no endemic species. The greatest richness is in

the Florida Parishes, east of the Mississippi River. St. Tammany Parish alone is home to

102 species. A secondary area of high richness is in the dissected uplands of central

Louisiana. Areas with the lowest species richness include the coastal marshes and

Mississippi River floodplain.

Sixteen species of amphibians (10 salamanders, 6 frogs) and 35 species of reptiles (17

turtles, 5 lizards, 13 snakes) are considered SGCN by LNHP (2015). The Dusky Gopher

Frog and the Ornate Chorus Frog are considered extirpated in Louisiana (last observed in

1967 and 1954, respectively), and follow-up surveys have been unable to relocate them at

historical sites or potential sites (Siegel and Doody 1992, Thomas 1996, Leonard et al.

2003). All marine turtles occurring in Louisiana are federally and state listed: three of the

five are endangered, and the Loggerhead Sea Turtle and Green Sea Turtle are threatened.

U.S. Fish and Wildlife Service (USFWS) recovery plans have been developed for each

(NMFS and USFWS 1991a, 1991b, 1992a, 1992b, 1993). Other federally-listed species

include the Gopher Tortoise (USFWS 1990a), Ringed Map Turtle (USFWS 1986), and

Dusky Gopher Frog (USFWS 2001). The Black Pinesnake and Louisiana Pinesnake are

candidate species for federal listing, with the Louisiana Pinesnake recently proposed for

listed as threatened.

b. Threats to Amphibians and Reptiles

As with other taxa, habitat fragmentation, degradation, and conversion resulting from

development, agriculture, and transportation infrastructure serve as major stressors to

many reptiles and amphibians. Magnitude of impact to these species is exacerbated by

their limited mobility which prevents escape to refugia. Annual movements undertaken

between breeding and non-breeding habitats characteristic of some reptile and amphibian

SGCN exposes individuals to vehicle strikes, Feral Cats, and other hazards. For those

species associated with upland habitats, including open pine systems, incompatible

habitat management practices such as fire suppression, roller-chopping, and bedding may

be an issue. For coastal species, the impacts of oil spills, SLR, and tropical cyclones may

be locally devastating. Amphibians are vulnerable to many of the same threats that were

discussed for other aquatic species (e.g., improper riparian zone management, climate

change, etc.), with species in ephemeral wetlands and smaller streams most likely to be

impacted. Over-collecting for the pet trade or for food has the potential to lead to or

accelerate declines of long-lived turtle species. Wanton killing of snakes may be a

significant source of mortality for some uncommon species such as Eastern Diamond-

backed Rattlesnakes. So called “ghost traps” (i.e., derelict crab traps) are well known as a

source of mortality for terrapins in some locations, and sea turtles are vulnerable to the

impacts of by-catch in the absence of turtle-excluder devices (TEDs). Sandbar-nesting

riverine turtles are vulnerable to human disturbance at nesting beaches, as well as nest

flooding resulting from inopportune water releases upstream of such beaches. Red

Imported Fire Ants are a serious threat to many terrestrial, adult amphibians and reptiles,

as well as to the eggs and hatchlings of aquatic turtles. Some native species, such as

Raccoons and Coyotes are also a significant source of mortality for some of these SGCN.

Approximately 160 species of birds occur as breeders or year-round residents in

Louisiana (Wiedenfeld and Swan 2000), and more than 300 additional species are known

to migrate through or spend the nonbreeding season in the state or its adjacent waters

(Cardiff et al. 2014). There are 91 species on the SGCN list of which 51 species are

considered rare and local, imperiled, or critically imperiled by the LNHP (2015).

Recovery plans have been developed by the USFWS for federally-listed birds including

the Whooping Crane, Red-Cockaded Woodpecker, Piping Plover, and Interior Least Tern

(USFWS 1994, 2003, 1996, 1990). The Brown Pelican was delisted in the U.S. Atlantic

coast, Florida, and Alabama in 1985 and was delisted in the rest of its range, including

Louisiana, in 2009. The Bald Eagle was delisted in 2007. The rufa subspecies of the Red

Knot was federally-listed as threatened in 2014.

Five of the nine extant or presumed extant, federally-listed bird species are believed

to be extirpated in Louisiana.

Despite sporadic, occasional reports of Ivory-Billed

Woodpecker (Campephilus principalis) sightings, observers have invariably failed to

document credible or compelling evidence of the persistence of this species in our state.

The most recent, presumed credible report was of a pair of birds observed in Pearl River

WMA in April 1999, but all subsequent attempts to document the woodpecker’s presence

in Louisiana were unsuccessful (Fitzpatrick 2002). With the presumed discovery of this

Passenger Pigeon (Ectopistes migratorius) and Carolina Parakeet (Conuropsis carolinensis), not included

in this figure, were once both commonly occurring species in Louisiana, but went extinct in the early

1900s.

SPECIES OF GREATEST CONSERVATION NEED LA WAP—OCTOBER 2015

species in Arkansas in 2004 (Fitzpatrick et al. 2005), LDWF made the decision to include

the Ivory-billed Woodpecker on the 2005 WAP SGCN list in the event of a confirmed re-

discovery here. However, the species is removed from the list of SGCN for this revision

due to the lack of recent, verifiable sightings; Ivory-billed Woodpecker is no longer

considered to occur in Louisiana by LDWF. Other species with historical range in

Louisiana but now considered extirpated here include Attwater’s Greater Prairie-Chicken,

Eskimo Curlew, and Bachman’s Warbler. Efforts are currently underway to reintroduce

the formerly-extirpated Whooping Crane to Louisiana.

b. Threats to Birds

Many threats discussed for other taxa also apply to birds, including habitat

degradation, fragmentation, and conversion resulting from development or agriculture.

For birds, habitats most in peril include Barrier Islands, threatened primarily by natural

system modification, climate change, SLR and subsidence, and tropical cyclones, and

coastal forests of all types (e.g., Coastal Live Oak-Hackberry Forest, Barrier Island Live

Oak Forest, etc.), threatened by a number of factors, many of which overlap those of

Barrier Islands. Additionally, the conversion of agricultural land from rice and crawfish

aquaculture to lower wildlife value crops is of concern for many wetland dependent

SPECIES OF GREATEST CONSERVATION NEED LA WAP—OCTOBER 2015

species. Migratory species may be threatened by habitat loss within their breeding and

nonbreeding ranges, including loss of stopover sites. Disturbance of nesting birds,

particularly of colonial nesting species, may greatly negatively impact productivity and

should be prevented. Stewardship at beach nesting bird colonies can be extremely

effective. Natural system modifications of all types, including fire suppression and

hydrological modification threaten a wide range of bird species. Aforementioned habitat

impacts and stressors listed below will likely exacerbate loss of birds when those impacts

are combined with effects of climate change. High mobility of birds may mitigate

impacts to some species, but others, particularly coastal obligates, remain at high risk due

to SLR.

In addition to loss of habitat or habitat function, birds suffer direct mortality from

many other anthropogenic sources including ingestion of plastics, electrocutions from

power lines, fisheries’ by-catch, collisions with infrastructure (e.g., communication

towers, wind turbines, power lines, glass windows, etc.), vehicle strikes, poisoning from

toxic releases, predation by outdoor cats, and many others. Although great strides have

been made in recent decades in addressing and reducing some sources of pollution,

including pesticides such as DDT, pollution of various types remains a threat to bird

SGCN. Inland, nearshore, and offshore oil spills pose serious direct threats to both inland

species and, particularly, coastal species, which frequently nest in high densities.

Although not yet a major issue in Louisiana, concern exists regarding the potential

impacts of wind farms on birds, especially in areas of high bird density (e.g., rice fields

with waterfowl or wading birds) or areas utilized by large, soaring species such as

vultures and eagles, which are killed disproportionately compared to other bird groups.

Mortality resulting from collisions with communication towers is significant, but may be

minimized, in part, by changing light schemes on these towers or even the structures

themselves. Glass windows kill more birds in the U.S. than all other mortality factors

except outdoor cats; more than 350 million birds are killed annually in the U.S. due to

window-strikes (Loss et al. 2014). Incorporation of bird-safe or bird-friendly building

design into new structures could aid in reducing this loss [see Audubon Minnesota’s

Bird-Safe Building Guidelines (2010) and American Bird Conservancy’s Bird-friendly

Building Design (2011)]. Reduction of the reflectance of existing windows and covering

windows with screen (traditional or natural materials) will reduce mortality.

The most insidious threat to birds is predation by Feral Cats (including outdoor,

owned cats), which are considered a Tier I invasive species in the 2015 WAP (Chapter

6). Cats kill far more birds annually in the U.S. than all other direct anthropogenic

sources (Loss et al. 2013), with current estimates exceeding 2 billion birds per year.

Other invasives, both plants and animals, threaten native birds as well, whether through

predation, competition for nest cavities or other resources, or habitat modification. In

addition, the full extent of intentional, illegal destruction of birds is unknown, but for

some high profile species, it is a conspicuous source of mortality.

 Create and restore Salt to Brackish marsh, preferably in blocks ≥10,000 acres,

containing areas of medium and tall height Smooth Cordgrass (Spartina

alterniflora), interspersed with ponds, tidal creeks, and bare ground areas.

9. Mammals

Seventy mammal species have been recorded in Louisiana or its adjacent waters

(Lowery 1974). Thirteen species are considered rare and local, imperiled, or critically

imperiled by the LNHP (2015). There are four federally-listed mammal species in

Louisiana that are considered SGCN. Recovery plans for the Louisiana Black Bear

(USFWS 1995b) and West Indian Manatee (USFWS 2001) have been developed by

USFWS. Both the Red Wolf (Canis rufus) and Florida Panther (Puma concolor) have

been removed from the SGCN list, as they no longer occur in the state. Three of the four

whale species included on the 2005 SGCN list have also been removed, as they do not

regularly occur in state waters, and therefore may not be impacted by conservation

actions within Louisiana.

b. Threats to Mammals

Louisiana’s mammal SGCN are highly diverse in ecology and habitat preference, and

as such, almost all of the 1

level threats identified by Salafsky et al. (2008) apply to at

least one mammal SGCN. Many of these species are subject to direct habitat loss and

degradation resulting from development and agriculture, as discussed for other taxa.

Marine mammals are at risk from oil spills and other toxic releases, and, as with birds,

wind farms pose a potential threat to many bats. Also of concern for bat SGCN is the

replacement of “bat-friendly” bridges with designs that are of lower value to these

species. Some SGCN, including predators, rodents, and bats, are subject to varying

degrees of human persecution. As with all SGCN, natural system modification is one of

the most serious threats to many mammals. One of the most high profile threats to bats is

White-nose Syndrome, which has not yet been documented in Louisiana, but has been

detected in neighboring states. Whether terrestrial or aquatic, all mammal SGCN are

potentially impacted by pollution. Finally, although many mammals are predicted to be

fairly resilient to the impacts of climate change, there is some level of risk, particularly to

range-restricted species.

SPECIES OF GREATEST CONSERVATION NEED LA WAP—OCTOBER 2015

D. General Conservation Actions

Rather than being specific to a single SGCN or particular suite of SGCN, the

following actions will provide benefits to many or all SGCN or natural communities,

thereby benefitting large numbers of SGCN. As with the conservation actions presented

earlier in this chapter, this list is plastic and not comprehensive. Actions are divided into

five categories: Partnerships, Education, Research and Inventory, Habitat Impact

Avoidance, and Stewardship Implementation.

1. Partnerships

 Partner with NGOs, state and federal agencies, industry, and private landowners

to promote conservation of natural communities.

 Partner with DOTD, particularly in planning phases, to address wildlife-vehicle

strike minimization measures such as creating wildlife crossings.

 Utilize social media outlets to engage, inform, and interact with the public about

wildlife habitats and their conservation.

 Work with the legislature to develop tax incentives for landowners to encourage

conservation of rare habitat types.

 Direct the curricula of the local chapters of the Louisiana Master Naturalist

Program; ensure that students are being trained in relevant subjects; frequently

utilize certified Master Naturalists to help accomplish conservation projects.

 Increase support for landowner outreach and citizen-based voluntary conservation

initiatives such as the Natural Areas Registry Program.

 Work closely with Interagency Review Team (IRT) to ensure that proposed

mitigation banks will have the highest possible ecological value; interact with

mitigation bank sponsors to assist with decision making, if requested.

 Partner with the Southeastern Regional Partnership for Planning and

Sustainability (SERPPAS) to develop and expand training opportunities for

prescribed burning certification and to promote prescribed fire and conservation

in the Southeast.

 Promote WAP priorities within the framework of the Southeastern Conservation

Adaptation Strategy (SECAS) in order to develop regionwide conservation

strategies for SGCN and their habitats.

2. Education

 Provide educational information on natural communities and their importance to

SGCN to landowners and managers through participation in outreach events,

presentations, and workshops, and through the LDWF website.

 Encourage the design of university curricula that emphasize natural habitat

diversity in fields of applied science (e.g. landscape architecture, landscape and

urban planning, and renewable natural resources conservation); communicate the

SPECIES OF GREATEST CONSERVATION NEED LA WAP—OCTOBER 2015

need for field biology training to University department heads and administrators,

as well as the Board of Regents.

 Promote education about the impact of invasive plant and animal species on

natural habitats and methods to eradicate or control invasives through literature,

radio and television, and interactive workshops.

 Provide information on WAP SGCN and associated habitats for teachers and

other workshop participants (Future Farmers of America (FFA), Envirothon, etc.)

to ensure their use in Louisiana schools.

 Develop and publish information regarding beneficial management practices and

desired habitat conditions for all habitat types.

 Increase number of publications picturing and describing Louisiana wildlife,

plants, and habitats (e.g. field guides, accounts of flora and fauna of particular

sites or habitats).

 Establish a television program that takes the audience across Louisiana,

introducing them to diverse habitats.

 Leverage resources such as the Teaming With Wildlife Coalition and Master

Naturalist chapters to improve public awareness of conservation issues.

3. Research and Inventory

 Intensify surveys to determine the current conservation status of all natural

communities and to gain additional information about poorly-known habitats.

 Engage the public in documenting and reporting species and habitat occurrences

through citizen science initiatives.

 Continue survey work to document “up-and-coming” exotic invasive species that

are expected to eventually have a negative impact on Louisiana’s biological

resources.

 Use remote sensing to determine location and extent of habitats, incorporating

ground truthing and involvement of scientists sufficiently versed in plant ecology.

 Continue and expand, as deemed appropriate, to investigate and quantify the

effects of oil spills on SGCN via additional research and monitoring, as well as

mechanisms to mitigate for such impacts.

4. Habitat Impact Avoidance

 Inform appropriate planning commissions about types of habitats and their

locations to avoid impact to these habitats.

 Provide habitat information to oil, gas, and seismic companies and encourage

resource survey and mining techniques that avoid or minimize impacts to wildlife

habitats.

 Create a web-based biodiversity information server to allow clients to determine

species and habitats potentially impacted by their proposed development projects.

SPECIES OF GREATEST CONSERVATION NEED LA WAP—OCTOBER 2015

5. Stewardship Implementation

 Promote the utilization of federal cost share programs (e.g. NRCS) to address

habitat conservation issues such as invasive species problems and implementation

of stewardship practices (e.g. prescribed burning).

 Provide funding and assistance to landowners for exotic species control in high

quality habitat occurrences.

 Increase the number of cost share/cost elimination programs that apply

stewardship practices on the landscape (e.g. Prescribed Burn Initiative); expand

existing programs to apply to additional habitats and increase their geographic

reach.

 Increase LDWF’s capability to apply stewardship on private lands by having

more certified prescribed fire applicators, more staff certified to apply herbicides,

and staff qualified to use mechanical equipment to improve habitat (e.g., brush

removal in prairies).
