Lax Water-milfoil (Myriophyllum laxum) GA: R Occurrence; Please consult with GDNR for survey efforts. Any of the above species may occur in suitable habitat in this HUC 10 watershed. Survey dates are provided for reference only. Please coordinate with your lead federal agency, Georgia Department of Natural Resources, or USFWS to determine if surveys will help assess project impacts to species of concern. Watershed Specific Concerns: There are federally listed aquatic/wetland and terrestrial species that occur or could occur in this watershed. If the project contains suitable habitat for listed species, please contact your lead federal agency to determine the appropriate next step for those species to inform their NEPA and ESA decisions. Coordination with Georgia Department of Natural Resources may also be helpful in those decisions. Critical Habitat: There is Critical Habitat designated under the Endangered Species Act for at least one species in this watershed. Please see the list above to determine which species. Please coordinate with our office to determine if your project will impact this habitat. Bats/Caves: Please determine if your project will impact caves or cave-like habitats. Please coordinate with Georgia Department of Natural Resources if your project will impact these habitats. Our records indicate that there is at least one named cave or habitat within 0.25 mi of a cave in this watershed. This cave could represent hibernacula for non-federally listed bat species. Frosted Flatwoods Salamander: Suitable habitat includes isolated depressional wetlands located in pine flatwoods. If this habitat occurs in the vicinity of the project area, it may represent potential breeding sites for this species. Minimizing impacts to wetland and pond habitats including impacts caused by fill, draining, and altered hydrology in areas where this species occurs can assist with its recovery. Bald Eagle: Bald Eagles and their nests are protected from take, including disturbance, under the federal Bald and Golden Eagle Protection Act. For information about Bald and Golden Eagles see the Service's regional web page: https://www.fws. gov/southeast/our-services/permits/eagles/ Wood Stork: The Wood Stork feeds in shallow emergent wetlands, ditches, pond margins, and coastal areas.

Minimizing potential impacts and ensuring water quality is preserved or enhanced is vital to the successful recovery of this species. If the project area is located within the Core Foraging Area (13 mile radius) of a Wood Stork rookery, additional considerations may be requested for unavoidable impacts to foraging and nesting habitats. Aquatics: Several federally or state-listed aquatic species and/or critical habitat for aquatic species occurs in this watershed. These species are sensitive to sedimentation and changes in water quality. Please note that Purple Bankclimber and Fat Three-ridge mussel species are only found in mainstem rivers (e.g., Flint River) and confluences with them. Please use guidance found in the Riparian Buffer, Streambank, and Stream Channel Protection and Water Quality Protection sections below. Please coordinate any avoidance and minimization efforts for federally listed species and their designated critical habitats with our office. Because of a high level of past survey effort in the watershed, surveys for aquatic species may not be necessary for federally listed species. Please coordinate with our office prior to conducting surveys for any of these species and in accordance with your Section 10(A)(1)(a) permit. Red-cockaded Woodpecker: Red-cockaded Woodpecker requires large expanses of mature (approximately 60-80 years old or older), open pine forest, preferably longleaf, slash, or loblolly pine or younger forests with artificial nesting cavities. Natural nest cavities are excavated in mature living pines and may take several years to complete. Red-cockaded woodpecker colonies require large, contiguous tracts of habitat, ranging in size from approximately 60-600 acres per family group, depending upon the quality of the habitat. Currently, its range is fragmented and most populations are found on public lands where timber harvesting has not been maximized. Pondberry: Habitat for Pondberry includes the edges of sandhill ponds and lime sinks, and it often occurs with pondspice. Surveys for this species are best conducted during flowering (late February–mid-March) and fruiting (August–October). American Chaffseed: Typical habitat for the American chaffseed consists of frequently burned longleaf pine savannahs, sandhills, and flatwoods, as well as moist, grassy areas around ponds within these habitats. This species only flowers in response to recent fire or management simulating fire (e.g., mowing or raking). Gopher Tortoise: This species requires well-drained, sandy soil for burrowing, abundant sunlight availability, and rich herbaceous vegetation for foraging. It is a characteristic species of the disappearing longleaf pine and wiregrass community, which includes sandhills, dry flatwoods,

  • Biological Status Report
    Georgia Blind Salamander Biological Status Review Report March 31, 2011 FLORIDA FISH AND WILDLIFE CONSERVATION COMMISSION 620 South Meridian Street Tallahassee, Florida 32399-1600 Biological Status Review for the Georgia Blind Salamander (Eurycea wallacei) March 31, 2011 EXECUTIVE SUMMARY The Florida Fish and Wildlife Conservation Commission (FWC) directed staff to evaluate all species listed as Endangered, Threatened or Species of Special Concern as of November 8, 2010 that had not undergone a status review in the past decade. Public information on the status of the Florida population of the Georgia blind salamander was sought from September 17 through November 1, 2010. A five-member Biological Review Group (BRG) met on November 9-10, 2010. Group members were Bill Turner (FWC lead), Ryan Means (Coastal Plains Institute), Kelly Jones (Virginia Tech), John Himes (FWC), and Paul Moler (independent consultant) (Appendix 1). In accordance with rule 68A-27.0012, Florida Administrative Code (F.A.C.), the BRG was charged with evaluating the biological status of the Georgia blind salamander using criteria included in definitions in 68A-27.001, F.A.C., and following protocols in the Guidelines for Application of the IUCN Red List Criteria at Regional Levels (Version 3.0) and Guidelines for Using the IUCN Red List Categories and Criteria (Version 8.1). Please visit http://myfwc.com/wildlifehabitats/imperiled/listing-action-petitions/ to view the listing process rule and the criteria found in the definitions. In late 2010, staff developed the initial draft of this report which included BRG findings and a preliminary listing recommendation from staff. The draft was sent out for peer review and the reviewers’ input has been incorporated to create this final report.

DOI:10.4311/2019LSC0125 BIODIVERSITY FROM CAVES AND OTHER SUBTERRANEAN HABITATS OF GEORGIA, USA Kirk S. Zigler1C, Matthew L. Niemiller2, Charles D.R. Stephen3, Breanne N. Ayala1, Marc A. Milne4, Nicholas S. Gladstone5, Annette S. Engel6, John B. Jensen7, Carlos D. Camp8, James C. Ozier9, and Alan Cressler10 Abstract We provide an annotated checklist of species recorded from caves and other subterranean habitats in the state of Georgia, USA. We report 281 species (228 invertebrates and 53 vertebrates), including 51 troglobionts (cave-obligate species), from more than 150 sites (caves, springs, and wells). Endemism is high; of the troglobionts, 17 (33 % of those known from the state) are endemic to Georgia and seven (14 %) are known from a single cave. We identified three biogeographic clusters of troglobionts. Two clusters are located in the northwestern part of the state, west of Lookout Mountain in Lookout Valley and east of Lookout Mountain in the Valley and Ridge. In addition, there is a group of tro- globionts found only in the southwestern corner of the state and associated with the Upper Floridan Aquifer. At least two dozen potentially undescribed species have been collected from caves; clarifying the taxonomic status of these organisms would improve our understanding of cave biodiversity in the state.

  • Feeding Efficiency in the Cave Salamander Haideotriton Wallacei
    Int. J. Speleol. 5 (1973), pp. 15-19. Feeding Efficiency in the Cave Salamander Haideotriton wallacei by STEWART B. PECK* INTRODUCTION Cave adapted animals often exhibit bizarre morphologies. A question of interest to students of evolu1ionary biology concerns the selective pressures which have led to these morphologi~al modifications. It is assumed from the frequency of conver- gence of "cave modifications" that they have an adaptive value for cave life. Poulson (1964) and Mitchell (1969) discuss the hypothesis and the literature that scarcity of food in caves may act as a forceful selective agent. The selection favors increased feeding and metabolic efficiency. The morphological changes result from this selection. Among the vertebrates, the American Amblyopsid cave fishes have been investi- gated (Poulson, 1963) and show increasing feeding and metabolic efficiency in conjunction with increased morphological specialization. There exists an even richer array of cave salamander species. Little has been reported on them beyond their morphology and raxonomy (Poulson, 1964). However, they present many oppor- tunities to investigate several aspects of the physiology and ecology of cave adaption and evolution. Brandon (1971) has reviewed aspects of morphological modification of North American troglobitic salamanders. Lee (1969) has reported on the feeding habits of the Georgia Blind Salamander, Haideotriton wallucei Carr. I would like to supplement his findings and to report an additional interpretation of the results. METHODS In September, 1968, eight specimens (20-26 mm snout to vent length) of H. wallacei were cap1ured in Gerard's Cave, Jackson County, Florida. The specimens were killed within one hour of capture in Chloretone, fixed for ] 2 hours in 4% formalin, and pre~;erved in 70% ethyl alcohol.

  • Limited Appearance Statement of Susan Woods Regarding Levy
    DOCKETED USNRC January 13, 2012 (10:15 am) OFFICE OF SECRETARY RULEMAKINGS AND ADJUDICATIONS STAFF I know you all are aware that building nuclear plants so close to the Gulf of Mexico, and on fragile coastal ecosystems, requires the utmost care in selecting sites and plans for construction. Any mistakes that result in damage to the Gulf Coast ecosystems will surely create an uproar on the scale of the BP oil spill. There are many of us here today who can comment on the science of that with more expertise than I have. My mission today is to remind all of you that you have a responsibility not only to the folks who will live within the shadow of the new nuclear plants, but also to those who cannot speak for themselves, and who are perhaps not even recognized by most of us. For this reason, I have given you copies of a paper written by Stephen J. Walsh of the US Geological Survey entitled Freshwater Macrofauna of Florida Karst Habitats. The aim of the paper is to emphasize several very important points: 1. You must understand that what affects salt water, as in the Gulf of Mexico, also affects freshwater habitats, as the water from the Gulf interacts significantly with the water of the Floridan Aquifer in the location you have chosen. 2. With the exception of those parts of Florida that have already used up freshwater resources in their area, and who have already turned to desalinization, the Floridan Aquifer is THE source of fresh water for all Floridians who live in the western half of the state.

    Salamander News No. 12 December 2014 www.yearofthesalamander.org A Focus on Salamanders at the Toledo Zoo Article and photos by Timothy A. Herman, Toledo Zoo In the year 2000, the Toledo Zoo opened the award-winning “Frogtown, USA” exhibit, showcasing amphibians native to Ohio, including one display housing a variety of plethodontid salamanders. Captive husbandry of lungless salamanders of the family Plethodontidae had previously been extremely rudimentary, and few people had maintained these amphibians in zoos. In this exhibit in 2007, the first captive reproduction of the Northern Slimy Salamander (Plethodon glutinosus) was achieved in a zoo setting, followed shortly thereafter by the Four-toed Salamander (Hemidactylium scutatum) A sample of the photogenic salamander diversity encountered during MUSHNAT/Toledo Zoo in an off-display holding fieldwork in Guatemala, clockwise from top left:Oedipina elongata, Bolitoglossa eremia, Bolitoglossa salvinii, Nyctanolis pernix. area.

  • Georgia Blind Salamander
    Georgia blind salamander Haideotriton wallacei Taxonomic Classification Kingdom: Animalia Phylum: Chordata Class: Amphibia Order: Caudata Family: Plethodontidae Genus/Species: Haideotriton wallacei Common Name: Georgia blind salamander Listing Status Federal Status: Not Listed FL Status: State Species of Special Concern FNAI Ranks: G2/S2 (Imperiled) IUCN Status: VU (Vulnerable) Physical Description The Georgia blind salamander is classified as an aquatic triglobite because it lives in an underground water environment and is adapted to dark caves. This small amphibian can reach a length of one to two inches (2.5 to 5 centimeters). Georgia blind salamanders have a white body with a yellow or pink tint, red external gills, and a long flat head (Means 1992, Florida Natural Areas Inventory 2001). They also have no eyes; an inherited evolutionary trait due to their dark habitat. Life History The diet of the Georgia blind salamander primarily consists of small aquatic invertebrates, such as seed shrimp and amphipods (Lee 1969). Little is known about the reproduction of the Georgia blind salamander. Pregnant females have been found in May and November (Means 1992). Georgia Blind Salamander 1 | Page Habitat & Distribution The Georgia blind salamander is confined to underground streams and pools in caves and sinkholes where it typically lives in complete darkness. This species is found in Jackson, Washington, and Calhoun counties in Florida, but can also be found in Dougherty and Decatur counties in Georgia (Hammerson 2004; Florida Natural Areas Inventory unpubl. data). Threats The Georgia blind salamander is affected considerably by the actions of humans. The main threats to the Georgia blind salamander are water pollution, water level changes, and collection by humans.
