United States Department of the Interior United States Department of the Interior FISH AND WILDLIFE SERVICE 200 Dulles Drive Lafayette, Louisiana 70506 August 30, 2019 Ms. Emlyn Smith Wildlife Biologist U.S. Forest Service Kisatchie National Forest Catahoula Ranger District Bentley, LA 71407 Dear Ms. Smith: Please reference your August 7, 2019, email and attachment, which transmits the North Gray Creek biological evaluation (BE) that assesses potential effects of proposed silvicultural activities in Compartments 89-93 on the Catahoula Ranger District of the Kisatchie National Forest in Grant Parish, Louisiana, to the threatened northern long-eared bat (NLEB; Myotis septentrionalis) and threatened Louisiana pearlshell (LPM; Margaritifera hembeli). The Fish and Wildlife Service (Service) has reviewed the information provided and offers the following comments in accordance with the Endangered Species Act (ESA) of 1973 (87 Stat. 884, as amended; 16 U.S.C. 1531 et seq.). As stated in the BE, the purpose to the proposed action is to implement specific resource management activities to move the habitat found within the project area toward the desired future conditions, in accordance with the Revised Land and Resource Management Plan (RLRMP, USFS 1999), with emphasis on maximizing commodity outputs while meeting all minimum management requirements. The proposed action would restore offsite loblolly pine forest to native longleaf and shortleaf pine forest and commercially thin forest stands to enhance health and vigor of the residual forest; to improve species composition, structure, function, and resiliency to insects and disease; and to harvest forest commodity. The proposed action also includes treatments to remove noxious weeds and non-native invasive plants. If implemented, the proposed action would be accomplished within the next five to ten years. The BE and “Table 3” of the BE provide a detailed description of the proposed action, summarized as follows: 1) Thinning approximately 1,523 acres of loblolly and slash pine stands, 1 2) Converting approximately 694 acres of offsite loblolly pine to native longleaf and shortleaf pine through pine regeneration activities, as follows: Clearcutting off-site species but leaving reserves of the existing shortleaf and longleaf pine within the regeneration stands; Preparing sites for planting through one or more of the following activities: herbicide application, burning, and mechanical chopping; Planting by hand longleaf and shortleaf pine seedlings; and Applying herbicides or prescribed burning to release the pine seedlings. 3) Applying herbicides (Triclopyr, Glyphosate & Imazapyr), mechanical removal, or prescribed burning on 2,158 acres of forested land to remove noxious weeds and non-native invasive plants. The BE states that the proposed project area is not found in the habitat management area for the endangered red-cockaded woodpecker (RCW, Picoides borealis) or the habitat management unit for the threatened Louisiana pinesnake (LPS, Pituophis ruthveni). Additionally, “Table 2” of the BE indicates that a RCW survey was conducted, which concluded that the RCW is not present in the proposed project area. “Table 2” also indicates that there is no suitable habitat for the LPS present in the proposed project area. Based on these reasons, potential impacts to these two species were not analyzed in the BE, and an ESA, Section 7 determination was not made by your agency. Northern long-eared bat According to the Final 4(d) rule and associated 2016 Biological Opinion (BO), incidental take is not prohibited unless it cuts or destroys known occupied maternity roost trees or any other trees within a 150-foot radius from the maternity roost tree during the pup season (June 1-July 31). The BE explains that there is a known maternity roost tree on the Catahoula Ranger District but the project location, approximately 7 miles from the maternity roost tree location, is outside of the 150-foot radius. In accordance with the final 4(d) rule and the 2016 BO, the planned project “may affect the NLEB but would not cause prohibited incidental take.” The Service agrees that your proposed project meets the provisions of the final 4(d) rule and the Service’s NLEB Programmatic BO (USFWS 2016) and that incidental take of NLEB from implementation of your proposed project is not prohibited (if it does not occur within 0.25 miles of known hibernacula or a 150-foot radius of a known maternity roost tree). Because the actions in your proposed project are consistent with the Land and Resource Management Plan for the Kisatchie National Forest (USFS 1999) and have been evaluated in the programmatic BO, consultation with our office is not needed for this proposed project, unless new location data is found for NLEB hibernacula or maternity roost sites within the proposed project area. Conservation Measures NLEB females do not exhibit annual site fidelity to maternity roost trees, and new breeders may be recruited into the area. Should these activities be conducted during the NLEB pup season, we recommend that your agency employs voluntary conservation efforts by conducting surveys of potentially affected suitable NLEB habitat within the proposed project area prior to project 2 implementation and during the same NLEB pup season (June 1 – July 31) that the project would occur to detect unknown, occupied maternity roost trees. If survey efforts find NLEB maternity roost sites, we request that a copy of the survey report with habitat and location data be provided to our office to assist us in better understanding the habitat use, distribution, and status of the NLEB in Louisiana. If an occupied, maternity roost tree is located within the proposed project area, follow conditions of the “Programmatic Biological Opinion on the Final 4(d) Rule for the Northern Long-Eared Bat and Activities Excepted from Take Prohibitions” (NLEB PBO; Service 2016). Page 5 of the NLEB PBO expresses that all activities that could cause incidental take of NLEB are prohibited within a 150-foot radius of known, occupied maternity roost trees. Thus, in accordance with the NLEB PBO, the proposed project must be conducted outside of a 150-foot radius of occupied, maternity roost trees. Voluntary implementation of our conservation recommendations given above will meet your responsibilities as a federal agency under section 7(a)(1) of the ESA and allow a better understanding of the habitat use, distribution, and status of the NLEB in Louisiana. These conservation recommendations are also consistent with the voluntary conservation measures provided on pages 6-7 of NLEB PBO (2016) and provided for your reference on the last page of this document. Louisiana pearlshell Under the provisions of Section 7 of the ESA, your agency has determined that implementation of the proposed action is “not likely to adversely affect” the LPM because the proposed action incorporates all protective measures for the LPM that are specified in the Final Environmental Impact Statement/Revised Land and Resource Mgmt Plan for the Kisatchie National Forest (USFS 1999). Accordingly, we concur with your determination for the LPM. The Service recommends that your agency contact our office for additional consultation if: 1) the scope or location of the proposed project is changed significantly, 2) new information reveals that the action may affect listed species or designated critical habitat; 3) the action is modified in a manner that may causes effects to listed species or designated critical habitat; or 4) a new species is listed or critical habitat designated. Additional consultation as a result of any of the above conditions or for changes not covered in this consultation should occur before changes are made and or finalized. We appreciate the opportunity to consult on the proposed projects. If you have questions, please contact Ms. Monica Sikes (337/291-3118) of this office. Sincerely, Joseph A.

Perform NLEB surveys according to the most recent Range-wide Indiana Bat/NLEB Summer Survey Guidelines. 2. Apply additional voluntary conservation measures, where appropriate, to reduce the impacts of activities on NLEBs. Conservation measures include: a. Conduct tree removal activities outside of the NLEB pup season (June 1 to July 31) and/or the active season (April 1 to October 31). This will minimize impacts to pups at roosts not yet identified. b. Avoid clearing suitable spring staging and fall swarming habitat within a 5-mile radius of known or assumed NLEB hibernacula during the staging and swarming seasons (April 1 to May 15 and August 15 to November 14, respectively). c. Manage forests to ensure a continual supply of snags and other suitable maternity roost trees. d. Conduct prescribed burns outside of the pup season (June 1 to July 31) and/or the active season (April 1 to October 31). Avoid high-intensity burns (causing tree scorch higher than NLEB roosting heights) during the summer maternity season to minimize direct impacts to NLEB. e. Perform any bridge repair, retrofit, maintenance, and/or rehabilitation work outside of the NLEB active season (April 1 to October 31) in areas where NLEB are known to roost on bridges or where such use is likely.

  • Biological Evaluation Usda - Forest Service, Kisatchie National Forest Catahoula Ranger District
    Catahoula RD – North Gray Creek 2 Aug 19 BIOLOGICAL EVALUATION USDA - FOREST SERVICE, KISATCHIE NATIONAL FOREST CATAHOULA RANGER DISTRICT North Gray Creek I. INTRODUCTION This report documents the findings of the Biological Evaluation (BE) for the proposed silvicultural activities in Compartments 89-93 on the Catahoula Ranger District of the Kisatchie National Forest. It also serves to provide the decision maker with information and determinations of the effects of proposed actions on proposed, endangered, threatened and sensitive (PETS) species and habitats so that the best decisions can be made regarding these species and the proposal. PETS species are species whose viability is most likely to be put at risk from management actions. Through the BE process the proposed management activities were reviewed and their potential effects on PETS species disclosed. Evaluation methods included internal expertise on species' habitat requirements, field surveys, Forest Service inventory and occurrence records, Final Environmental Impact Statement/Revised Land and Resource Management Plan for the Kisatchie National Forest, the recovery plans for the the red- cockaded woodpecker (RCW) and Louisiana pearlshell mussel (LPM) and the draft recovery plan and candidate conservation agreement (CCA) for the Louisisana pine snake (LPS). This biological evaluation was prepared in accordance with Forest Service Handbook 2609.23R and regulations set forth in Section 7 (a)(2) of the Endangered Species Act. A botanical evaluation was done separately to address impacts on sensitive and conservation plants. PURPOSE AND NEED: Differences between current and desired conditions have been identified within the project area. In order to move the project area toward the desired conditions, specific resource management actions were identified and developed.

  • BIOLOGICAL EVALUATION (Conservation Species) USDA FOREST SERVICE Kisatchie National Forest Winn Ranger District
    BIOLOGICAL EVALUATION (Conservation Species) USDA FOREST SERVICE Kisatchie National Forest Winn Ranger District Mendenhause Project Compartments 51, 52, and 56 INTRODUCTION: The purpose of this Biological Evaluation (BE) is to ensure that Forest Service actions do not contribute to the loss of viability of any native or desirable non-native animal species. This BE documents likely effects of management actions on populations of conservation species of concern as determined by the Louisiana Natural Heritage Program (LNHP). Such species are those, whose viability is most likely to be put at risk from management actions. Information presented here is used to ensure that such species are maintained at, or are moving toward, viable population levels. Populations of other species (those at less risk of losing viability) are maintained by creating and maintaining a diversity of habitat types distributed across the National Forest in accordance with Forest Plan Standards and Guidelines. Through this combination of approaches, viable populations of all species are maintained. A review of the Louisiana Rare Animal Species list and the Forest Geographic Information System (GIS) records was conducted to determine which species would possibly occur within the project site. The general biology of the species, personal communication with experts, and literature searches were used to determine the potential effect proposed actions, including the no action, would have on species considered likely to occur within the project area. The aforementioned research was conducted considering the best available science, and the potential effects discovered are discussed in this BE. PURPOSE AND NEED: Differences between current and desired conditions have been identified within the project area.

WALLS Department of Biological Sciences, McNeese State College, Lake Charles, Louisiana The genus Faxonella (Creaser, 1933) was diagnosed by Fitzpatrick (1963), who recognized two species, F. clypeata (Hay, 1899) and F. beyeri (Penn, 1950). The new species here described brings to three the number of known species. Two of these, F. beyeri and F. creaseri (new species), are endemic to Louisiana. I would like to thank Dr. Joe B. Black, McNeese State College, for the loan of specimens and for his patience and assistance in preparing this description. Thanks are also due to Messrs. Norman Arnold and Frank Amsden for providing transportation and assistance in collecting. Faxonella ereaseri new species Diagnosis: Lateral rostral spines and cervical spines absent; rostrum short and broad, one and one-half or fewer times as long as broad. Shape of chela ( Fig. 4) and carapace as in Faxonella clypeata and F. beyeri; areola variable, 25.9-33.1 percent of carapace length ( average 30.0), and 2.3-5.3 times as long as broad ( average 3.8).

  • Chapter 1. Introduction
    INTRODUCTION LA WAP—JUNE 2015 CHAPTER 1. INTRODUCTION A. Conservation and Management of Wildlife and Fisheries Resources in Louisiana In Louisiana, the Department of Wildlife and Fisheries (LDWF) is the government agency charged with the conservation and management of wildlife and fishery resources in the state, including aquatic and terrestrial vertebrate and invertebrate species. LDWF is authorized to execute the laws enacted for the control and supervision of programs relating to the management, protection, conservation, and replenishment of wildlife, fish, and aquatic life, and the regulation of the shipping of wildlife, fish, furs, and skins. LDWF is organized into four appropriated budget offices: Secretary, Management and Finance, Wildlife, and Fisheries. 1. Mission Statement: The Louisiana Department of Wildlife and Fisheries (LDWF) is charged with the conservation and management of Louisiana’s natural resources, including both aquatic and terrestrial species and habitats. LDWF’s mission is to manage, conserve, and promote wise utilization of Louisiana’s renewable fish and wildlife resources and their supporting habitats for the social and economic benefit of current and future generations; to provide opportunities for study, utilization, and enjoyment of these resources; and to promote a safe and healthy environment for the users of the resources. B. Problem and Need for a Wildlife Action Plan 1. Background: Early in the twentieth century, many of America’s once numerous fish and wildlife species were on the verge of extinction. In the 1930s, this situation began to change as harvests were better regulated, wildlife management areas and refuges were created, and game species populations were augmented or restored with translocated animals.

Crandall; e-mail: [email protected] (Received 13 May 2017; accepted 16 June 2017) ABSTRACT The freshwater crayfishes are a group of decapod crustaceans that have played a critical role in a diversity of biological studies, from physiology, to ecology, neurobiology, conserva- tion, and evolution. Central to many of these fields of study is the dependence on a robust taxonomic framework for accurate communication relating to species diversity and associated attributes. Despite a huge body of taxonomic work since Linnaeus, there has never been a single, comprehensive taxonomic summary of all the species of crayfish of the world. There has also been an abundance of recent taxonomic work in terms of new species descriptions and taxonomic insights gained from a variety of phylogenetic studies. Here we gather diverse taxonomic and phylogenetic information into a single resource. We develop an updated clas- sification system that includes all the crayfishes worldwide and taxonomic changes to better reflect the current phylogenetic knowledge of the group. We also include all the fossil crayfish taxa for a complete classification of extant and extinct crayfishes.

Hobbs, Jr. SMITHSONIAN INSTITUTION SMITHSONIAN INSTITUTION PRESS Washington, D.C. 1989 ABSTRACT Horton H. Hobbs, Jr. An Illustrated Checklist of the American Crayfishes (Decapoda: Astacidae, Cambaridae, and Parastacidae). Smithsonian Contributions to Zoology, number 480, 236 pages, 379 figures, 1989.—This alphabetical list consists of the names of all of the American crayfishes, including two fossil species, that were described prior to 1 January 1988. In the treatment accorded each specific or subspecific taxon there is a synonymy citing alterations in generic and subgeneric assignments, erroneous spellings, and synonyms. References are also made to recent descriptions, discussions, and keys. The composition and locations of type series are cited, as are the type locality, range, and habitat of each. Nomina nuda that have been neither validated nor synonymized with other crayfish taxa, together with two names suppressed by the International Commission on Zoological Nomenclature, are listed separately. Comparable illustrations, which are arranged in related species groups, are presented for each of the 379 recognized extant species and subspecies. Appendix 1 provides an alphabetical list of American crayfishes and the countries, states, and/or provinces in which they live. Appendix 2 consists of an alphabetical list of American countries and states, or provinces, and their crayfish faunas; also cited are references to studies that pertain either directly to them or which should be helpful in studies of them. Appendix 3 includes information comparable to that in the main body of the checklist on crayfishes described during 1988 and 1989.
