Freshwater mussels (Unionidae) are among the most imperiled groups of organisms in the world. Unionids are plagued with a lack of basic information regarding species distributions, life history characteristics, and ecological and biological requirements. We assessed the influence of hydrologic factors on the occurrence of the Suwannee Moccasinshell, Medionidus walkeri, a federally threatened freshwater mussel species endemic to the Suwannee River basin in Georgia and Florida. We also assessed the influence of survey effort on detection of M. walkeri during field surveys. All current (2013-2016) mussel survey records in the Suwannee River Basin were compiled, and cumulative discharge contributed by upstream springs...

Nature’s Network Conservation Design depicts an interconnected network of lands and waters that, if protected, will support a diversity of fish, wildlife, and natural resources that the people of the Northeast and Mid-Atlantic region depend upon. This map serves as the “cover page” for the Nature’s Network (naturesnetwork.org) suite of products: it outlines some of the most important natural areas in the region and provides an entry point to learn more about the information used to identify them. The Conservation Design represents a combination of three Nature’s Network products: 1) the terrestrial core-connector network, 2) aquatic core areas, and 3) core habitat for imperiled species. The Terrestrial Core-connector...

Habitat Importance for Imperiled Species is one of a suite of products from the Nature’s Network project. Nature’s Network is a collaborative effort to identify shared priorities for conservation in the Northeast, considering the value of fish and wildlife species and the natural areas they inhabit. Important Habitats are a group of critical terrestrial and aquatic habitats for imperiled species. The dataset was created by studying the overlap of 600 Species of Greatest Conservation Need (SGCN) and their documented occurrences (from tens of thousands of data points) with terrestrial and aquatic habitats mapped by The Nature Conservancy and UMASS. *NOTE - The download of this data also includes Habitat Condition...

Habitat Condition for Imperiled Species is one of a suite of products from the Nature’s Network project (naturesnetwork.org). Nature’s Network is a collaborative effort to identify shared priorities for conservation in the Northeast, considering the value of fish and wildlife species and the natural areas they inhabit. This product represents a regional network of habitats critical for sustaining populations of imperiled species, currently based on over 600 Species of Greatest Conservation Need (SGCN).A number of additional datasets that augment or complement Habitat Condition for Imperiled Species, including Core Habitat for Imperiled Species, are also available in the Nature’s Network gallery. A detailed technical...

This map combines the predicted distributions (whenever possible) and the spp. occurrences (from the FNAI element occurrence database when we don't have a predicted distribution) for the 16 species included in the Wildlife Best Management Practices. This will be used in conjunction with PFLCC's Working Lands Priority Resource, and potentially spatial data on Notices of Intent for Wildlife on Agricultural and/or Forestry Lands. Sources for data: Harlequin Darter, Bluenose shiner, and Blackmouth shiner -- predicted distributions came from Fish Species Distribution Modeling (2013) Crystal Darter, Tessellated Darter, Santa Fe Crayfish, and Georgia Blind Salamander -- spp. occurrences from FNAI element occurrence (from...

NOTE: RESTRICTED DATA. This dataset comprises Unusually Sensitive Areas (USAs) data for ecological resources in the state of Wyoming. In accordance with pipeline safety laws (49 U.S.C. Section 60109), PHMSA is required to identify areas unusually sensitive to environmental damage in the event of a hazardous liquid pipeline accident. Through interactions with various regulatory agencies, pipeline operators, private contractors, non-profit conservation organizations, and the general public, a process has been developed and adopted by PHMSA to identify USAs for ecological resources. The process consists of identifying a set of candidate ecological resources using approved data sources, and subjecting candidates to...

Core Habitat for Imperiled Species is one of a suite of products from the Nature’s Network project (naturesnetwork.org). Nature’s Network is a collaborative effort to identify shared priorities for conservation in the Northeast, considering the value of fish and wildlife species and the natural areas they inhabit. This product represents a regional network of the most intact of habitats estimated to be most important for sustaining populations of imperiled species, currently based on over 600 Species of Greatest Conservation Need (SGCN).A number of additional datasets that augment or complement Core Habitat for Imperiled Species, including Habitat Condition for Imperiled Species (the more extensive dataset from...
