Candidate Species and Species at Risk
Species at Risk on Department of Defense Lands: 2014 Updated Analysis, Report, and Maps - Report (Legacy 14-772) (PDF)
In this report, NatureServe provides two major types of analyses which are detailed in the results section: (1) analyses of species at risk that occur only or mostly on DoD lands or that are otherwise highly dependent on DoD management for their survival, and (2) overall summary analyses of installations with high numbers or densities of species at risk. These analyses aim to help DoD to direct resources towards both high priority species at risk and high priority installations.
Assessing the presence and distribution of 20 Hawaiian yellow-faced bee species, currently under status review and/or designated as species of concern, on lands adjacent to military installations on Oahu and Hawaii Island (Legacy 11-104) (PDF)
The endemic Hylaeus bees are critical pollinators in native ecosystems in Hawai‘i. Seven species are proposed for listing as endangered, and many more are rare and potentially endangered. We surveyed 40 localities on O‘ahu, 56 on Hawai‘i, and approximately 70 km of the coastline of Hawai‘i for 23 species of native Hylaeus, including four added during the course of the project.
Workshop to Improve Inter-Agency Cooperation and Collaboration for Managing Sustainable Populations of Mohave Ground Squirrels - Report, January 2013 (Legacy 11-121) (PDF)
The objectives of this workshop were to: 1) improve inter-agency cooperation, collaboration, and understanding of various management and regulatory actions; 2) review and summarize the current literature for MGS and similar ground squirrel species; 3) bring together recognized experts so there could be an exchange of ideas; 4) increase the standardization and quality of field data collection so more informed, adaptive management, and regulatory decisions can be made; 5) seek the input of workshop participants on how to enhance conservation efforts for MGS through improvements in field methodologies, protocols, and management strategies and to map a course to implement these ideas through a conservation strategy; 6) distribute information from the workshop to natural resource managers and regulatory personnel and other interested parties involved in the conservation of MGS through website posting(s); 7) provide a base from which other future discussions, meetings, and information exchanges will happen; and 8) develop a technical report that discusses the viewpoints of workshop participants on how best to standardize field protocols to survey and detect MGS and to monitor population trends, and a number of other topic areas. This report details the workshop and includes recommendations and an appendix with all PowerPoint presentations.

Cerulean Warbler Occurrence Atlas - Report, December 2011 (Legacy 10-429) (PDF)
Cerulean Warbler Occurrence Atlas for Military Installations - Final Report, December 2011 (Legacy 10-429). The Cerulean Warbler Occurrence Atlas for Military Installations will evaluate the CERW status on all Department of Defense (DoD) lands with appropriate habitat that fall within the species’ breeding range (plus a 100-mile buffer). This will allow the DoD to manage proactively for CERW and to forge partnerships with state-level entities concerned with rare neotropical migrants, such as Important Bird Area programs and natural resource agencies. This report details the second year of a three-year effort.
Le Conte's Thrasher (Toxostoma lecontei) Occupancy and Distribution - Report (Legacy 10-343) (PDF)
Le Conte’s Thrasher (Toxostoma lecontei) Occupancy and Distribution: Barry M. Goldwater Range and Yuma Proving Ground in Southwestern Arizona - Year One Final Report, September 2012 (Legacy 10-343). Le Conte’s Thrasher is an uncommon permanent resident of sparsely vegetated landscapes within the San Joaquin Valley, Kern River basin, Owens Valley, Mojave Desert, and the Lower Colorado River Valley subdivision of the Sonoran Desert biotic community in the southwestern United States. This species is listed as a Bird of Conservation Concern by US Fish and Wildlife and is a ranked species by CA and AZ. Anthropogenic disturbances within the distribution of the Le Conte’s thrasher (e.g., military training, recreational activity, habitat fragmentation, etc.) have the potential to cause direct mortality and reduce habitat quality through impacts to vegetation structure and soil characteristics. While impacts to habitat on active military training areas can be substantial, these ranges provide important refuges for thrashers and their habitat.
Species at Risk on Department of Defense Lands: Updated Analysis, Report, and Maps - Final Report, July 2011 (Legacy 10-247) (PDF)
This analysis represents an update of a previous analysis by NatureServe funded by the Department of Defense Legacy Program that was based on 2002 species location data. A key finding of this updated 2011 assessment is that the total number of species at risk on DoD lands remained similar to the numbers based on the 2002 data (519 species at risk were reported in 2011, compared to 523 species reported in the 2004 report), despite an increase of over 25,000 new species at risk element occurrences in NatureServe's databases since 2002. A set of detailed excel spreadsheets accompany this report and are presented separately.
Landscape-Level Habitat Associations and Phylogenetics of Desert Tortoises on Southwestern Arizona Military Ranges Managed by the Army, Air Force, and Marines - Final Report, March 2012 (Legacy 09-385) (PDF)
Given the possibility of future ESA listing and the challenges that such a decision would impose upon the Department of Defense (DoD), it is prudent to understand the distribution of desert tortoises on military ranges within the Sonoran Desert so that appropriate management decisions can be made to reduce conflicts while maintaining the military readiness mission. The primary objective of this study was to develop a landscape-level predictive habitat model for desert tortoises inhabiting the Yuma Proving Ground and Barry M. Goldwater Range in southwestern Arizona. The secondary objective of this study was to characterize the phylogenetic grouping of desert tortoises inhabiting these DoD managed lands. This report contains methods, models, results and a set of detailed maps.
Strategy for the Cooperative Recovery of Rare Species Affecting Training Ranges - Final Report, November 2011 (Legacy 09-213) (PDF)
The project's primary objective is to maintain military training flexibility by precluding the need for Endangered Species Act listing of the four candidate species that occur on the grasslands of Joint Base Lewis-McChord: Taylor's checkerspot and Mardon skipper butterflies, the streaked horned lark, and Mazama pocket gopher. The project works toward this goal by promoting cooperative ecoregional recovery of these rare species throughout their range in order to share the burden of species recovery over a variety of partners and locations. This report describes the project's achievements, evaluates cooperative conservation techniques as a whole, and includes lessons learned.
Strategy for the Cooperative Recovery of Rare Species Affecting Training Ranges: Native Seed Production Strategy - A Key Piece of Puget Sound Prairie Conservation (Legacy 09-213) (PDF)
Restoration and active management is a critical conservation strategy for South Sound prairies. The majority of remaining prairie sites have been degraded due to the invasion of pest plants, fire suppression and other threats. Restoration on these sites has progressed through initial control efforts for most pest plants and is now in the process of shifting to enhancement of native species, especially to create habitat for several of the rarest species in the prairies, the prairie butterflies. Direct seeding of species, especially after sufficient site preparation, is a successful technique. In order to restore habitat at scale a sufficient source of native seed is needed yearly.
Cerulean Warbler Occurrence Atlas for Military Installations - Report Year One, December 2009 (Legacy 09-429) (PDF)
The Cerulean Warbler (CERW, Dendroica cerulea) is a small wood-warbler that nests and forages in the upper canopy of mature forests. Current information indicates that CERW are declining. The Cerulean Warbler Occurrence Atlas for military installations will evaluate the CERW status on all DoD lands with appropriate habitat that fall within the species breeding range (plus a 100-mile buffer). This will allow DoD to manage proactively for CERW and to forge partnerships with state-level entities concerned with rare Neotropical migrants, such as Important Bird Areas programs and natural resource agencies. The long-term goal of all CERW management activities is to support the population and to prevent the federal listing of the CERW under the Endangered Species Act. This report details the first year efforts for this project.
Propagation of Species At Risk Atlantic Pigtoe on Military Installations-Final Report April 2010 (Legacy 09-450) (PDF)
The Department of Army has identified the Atlantic Pigtoe Mussel as a Species at Risk (SAR) with potential for detrimental impact on the military mission if federally listed as either threatened or endangered. The Nottoway River on ARNG-MTC Fort Pickett, VA is home to one of only two known stable populations of the Atlantic Pigtoe Mussel left in Virginia, and perhaps the world. Populations are in precipitous decline throughout the southeast, and expert consensus is that the species currently warrants federal listing. This project details the first year's efforts towards propagating the species and introducing new populations into its habitat
Migratory Linkages of Burrowing Owls on DoD Installations and Adjacent Lands - Final Report, December 2010 (Legacy 09-243) (PDF)
Burrowing Owl populations have declined throughout the Western U.S. and Canada, and they have been extirpated from the periphery of their breeding range. Despite these declines, they appear to be increasing in other areas. This project seeks an explanation for this paradox. That is, breeding populations might be redistributing themselves rather than declining. This report details the findings of this 5 year effort. This work provides a landscape-scale view of movements among Burrowing Owl populations which will allow conservation managers to direct their efforts appropriately. This information is vital to supporting the military mission because it will help identify the management role of DoD for conserving this species in the U.S., potentially help prevent further listing efforts for a species that is still rather common on DoD installations, and document movement patterns of a bird that breeds on many DoD installations in the region.
Migratory Linkages of Burrowing Owls on DoD Installations and Adjacent Lands - Final Report, 2005-2008 (Legacy 05 through 08-243) (PDF)
Some populations of Burrowing Owls have declined to the decree that listed may be a possibility. Burrowing Owls breed and/or overwinter on dozens of DoD installations throughout the western U.S. and, hence, any changes in their status may affect the military mission.
