Santa Fe cave crayfish Procambarus erythrops Taxonomic Classification Kingdom: Animalia Phylum: Arthropoda Class: Crustacea Order: Decapoda Family: Cambaridae Genus/Species: Procambarus erythrops Common Name: Santa Fe cave crayfish (also known as the Sim’s Sink crayfish) Listing Status Federal Status: Not Listed FL Status: State Species of Special Concern FNAI Ranks: G1/S1 (Critically Imperiled) IUCN Status: EN (Endangered) Physical Description The Santa Fe cave crayfish is a mid-sized crayfish that can reach a length of 3.5 inches (8.9 centimeters). This species is white with red-toned eyes (Florida Natural Areas Inventory 2001). Life History It is not clear what Santa Fe cave crayfish feed on, however, they are probably detritivores – feed on decomposed organic matter (NatureServe 2010). Males capable of reproduction are found between the months of January and July, with mating occurring between March and July. There is no data on spawning or the amount of young produced, as no egg-bearing female has ever been found (NatureServe Explorer 2010, Franz 1994). Habitat & Distribution Santa Fe cave crayfish inhabit groundwater areas in caves and sinkholes in southern Suwannee and southwestern Columbia counties in Florida (Florida Natural Areas Inventory 2001, Franz 1994, Franz et al. 1994, NatureServe 2010, Tom Morris pers. comm. 2010). Santa Fe Cave Crayfish 1 | Page Threats Habitat degradation seems to be the biggest threat to the Santa Fe cave crayfish. The change of its habitat’s water system and weathering rock flows can potentially threaten the Santa Fe cave crayfish population (NatureServe 2010). Other threats include the dumping of garbage in vulnerable areas, pollution of groundwater, and the effects of mining on the position of the water table (Florida Natural Areas Inventory 2001). Conservation & Management The Santa Fe cave crayfish is protected as a State Species of Special Concern by Florida’s Endangered and Threatened Species Rule. -Biological Status Review (BSR) -Supplemental Information for the BSR Other Informative Links Florida Natural Areas Inventory International Union for Conservation of Nature References Florida Natural Areas Inventory. 2001.

Many species of freshwater crayﬁsh of the endemic Australian genus Euastacus are threatened with extinction. Routine monitoring of most Euastacus species is minimal, and a subsequent lack of information has hampered prioritization of conservation and management efforts. 2. The present study investigated population parameters and temporal changes in abundance in a disjunct population of Euastacus bispinosus. This occurs at the western extent of the range of the species in the state of South Australia (SA) and inhabits a groundwater-dependent karst habitat distinct from the larger population in the Victorian Glenelg basin. 3. Euastacus bispinosus was recorded at sites within seven karst rising-springs as well as two isolated locations (sinkhole and cave), which expanded the extent of occurrence of the species in SA, but the area of occupancy remains limited. Most subpopulations contained low numbers, had little or no signs of recruitment, were dominated by large crayﬁsh, and demonstrated a high incidence of gonopore aberrations.

Florida Fish and Wildlife Conservation Commission ii EXECUTIVE SUMMARY EXECUTIVE SUMMARY This plan was developed to guide conservation actions for the Santa Fe cave crayfish (Procambarus erythrops), a species endemic to Florida and known only from several caves and sinkholes in southern Suwannee and Columbia counties. This crayfish has only been known to science since 1975, and a great deal remains to be learned about its natural history and extent of distribution. A determination of how closely known sites are connected through the aquifer will provide information about the species’ vulnerability, genetic variation, and population size.

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.

Jackson, Ph.D., Senior Research Zoologist Florida Natural Areas Inventory (FNAI) Project Biologist David T. Almquist, Invertebrate Zoologist, FNAI Project Assistants Dean Jue, Florida State University Glenn Woodsum, Data Manager, FNAI Aubrey Davis, Field Zoologist, FNAI Sally Jue, Conservation Lands Biologist, FNAI Takesha Henderson, Assistant Invertebrate Zoologist, FWC Dates Covered 1 July 2005– 30 May 2008 Date Submitted 30 May 2008 i ABSTRACT The goal of this multi-year project was to expand and enhance informational databases that the Florida Natural Areas Inventory (FNAI) maintains to describe and track invertebrates of conservation concern in the state. Data contained in these databases are directly available to state agencies, with summary data available to the public via the Internet (both through FNAI‘s web site and NatureServe Explorer). Since project inception, FNAI instigated tracking of more than 200 taxa, nearly doubling its prior list of tracked taxa developed during more than 2 decades of previous work. Newly tracked taxa represented the following groups (and numbers): snails (12), spiders (2), amphipods (1), crayfish (2), springtails (2), mayflies (1), dragonflies and damselflies (5), grasshoppers (14), stoneflies (11), beetles (56), scorpionflies (1), caddisflies (24), butterflies and moths (71), bees (1), and velvet ants (3). Most of these taxa are endemic to Florida or the Southeast. We collated and entered information pertaining to rarity and endangerment for all of the new taxa as well as most of the 279 previously tracked taxa.

Letter to FWS on Reviews of Southeast Species
June 8, 2018 Bridget Fahey Division Chief for Conservation and Classification U.S. Fish and Wildlife Service 1849 C Street, NW Washington, DC 20240 Gary Frazer Assistant Director -- Ecological Services U.S. Fish and Wildlife Service 1849 C Street, NW Washington, DC 20240 Dear Mr. Frazer and Ms. Fahey: We are writing to comment on 61 southeastern species for which the Center for Biological Diversity filed a petition seeking Endangered Species Act protection on April 20, 2010. On September 27, 2011 the Service determined that the species may warrant protection and issued “positive 90-day findings” on their protection (76 FR 59836) The Service should have thus initiated status reviews and published listing proposals or not warranted findings by 2012. The Service is now six years overdue in completing required status reviews for these species. In November 2017 the Center learned from concerned citizens that the Service was considering withdrawing positive 90-day findings for dozens of species absent completing 12-month status reviews as mandated by the Act. Because the Act clearly requires the Service to publish 12- month findings for species once the agency has determined that they may warrant protection, it would be clearly unlawful for the Trump administration to reverse the Obama administration’s “may warrant protection” determinations for these 61 imperiled species. The Center is deeply concerned about this unprecedented assault on the Endangered Species Act. In an effort to take a more cooperative approach, the Center contacted the Service and asked to review the list of species which were under threat of not receiving completed status reviews and to consider withdrawing some if information indicated this was warranted.

Santa Fe Cave Crayfish Biological Status Review Report
Santa Fe Cave Crayfish 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 Santa Fe Cave Crayfish (Procambarus erythrops) March 31, 2011 EXECUTIVE SUMMARY The Florida Fish and Wildlife Conservation Commission (FWC) directed staff to evaluate all species listed as 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 Santa Fe cave crayfish (Procambarus erythrops) was sought from September 17 to November 1, 2010. The members of the Biological Review Group (BRG) met on November 18, 2010. Group members were David Cook (FWC lead), Paul Moler (independent consultant), and Richard Franz (University of Florida/Florida Museum of Natural History, Emeritus) (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 Santa Fe cave crayfish using criteria included in definitions in 68A-27.001, F.A.C., and following the 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.

Distribution and Evolution of Florida's Troglobitic Crayfishes .1
.1 DISTRIBUTION AND EVOLUTION OF FLORIDA'S TROGLOBITIC CRAYFISHES RICHARD FRANZ AND DAVID S. LEE' ABSTRACT: The current knowledge of Florida's troglobitic crayfish fauna is discussed, inter- pretations of distributional and ecological patterns are reviewed, and an explanation of their evolutionary history is attempted. These crayfishes are restricted to certain geological formations that have light to nonexis- tent elastic overburdens. Areas with moderate to heavy accumulations over the carbonate rocks lack these crustaceans. The Crystal River Formation, a group of highly soluble Eocene limestones, is the most important geological element influencing the distribution of most Florida cave-dwelling crayfishes. Members of the Procambarus lucifugus complex (with the possible exception of an undescribed species from Lake County), Procambarus pallidus, Troglocambarus maclanei, and Cambarus cry ptodytes, are apparently confined to this for- mation. The remaining species are confined to other limestones (Procambarus acherontis and Procambarus species from Lake County in the Hawthorne Formation, Procambarus milleri in the Miami Oolite, Procambarus horsti and Procambarus orcinus in the St. Marks Forma- tion). Field observations suggest that available sources of food energy dictate which species groups inhabit particular cave systems. Species complexes that are most restricted to en- vironments which provide large accumulations of organic detritus become ecologically and geographically isolated from other populations and exhibit increased speciation. For example, members of the Procambarus lucifugus complex seem to have demanding energy budgets and occur only in localized karst areas exhibiting mature features and high energy input. Dependency on constant energy supplies provided by large sinkhole entrances and/or bat roosts probably limits their dispersal ability.

Pegasus Engineering From: Andrew Holland, Environmental Scientist MICHAEL G. CZERWINSKI, P.A., ENVIRONMENTAL CONSULTANTS Date: November 4, 2015 Subject: Results of Cursory Biological Assessment MICHAEL G. CZERWINSKI, P.A., ENVIRONMENTAL CONSULTANTS (MGC) contracted with Pegasus Engineering to perform a cursory biological assessment of a proposed revised road access and pond locations (subject site) associated with the larger Citrus County Highway 491 Widening Project. MGC had previously conducted a larger scale biological assessment of the entire widening corridor, including areas directly adjacent to the subject site assessment area in September, 2013. The new proposed ponds and road access areas were added due to revisions to the scope and drainage service area of the larger road widening project. Preliminary site plans depict the creation of two stormwater ponds to be constructed and a new road access of approximately 1,400 linear ft. to be established within the subject site limits. The subject site, comprising approximately 36 acres, is located directly east of the Audubon Park medical offices and is located approximately one mile north of the intersection of State Road 44 and County Road 491 in Sections 33 & 34, T18S, R18E and sections 3 & 4, T19S, R18E in Lecanto, Citrus County, Florida.
