A comprehensive scientific study of tiger habitats finds that the big cats reside in 40 percent less habitat than they were thought to a decade ago. Tigers now occupy only 7 percent of their historic range. This landmark study, Setting Priorities for Conservation and Recovery of Wild Tigers: 2005-2015, commissioned by the Save The Tiger Fund and produced by some of the world's leading tiger scientists at World Wildlife Fund, Wildlife Conservation Society, the Smithsonian's National Zoological Park and Save The Tiger Fund, calls for specific international actions to safeguard remaining populations. This dataset shows large areas of habitat in the extirpated portion of the tiger's range, including China, Central Asia,...
These data identify (in general) the areas where final critical habitat for the bull trout (Salvelinus confluentus) occur.
Colorado squawfish (Ptychocheilus lucius), were subjected to dilutions of saline water from natural springs near Glenwood Springs, Colorado, to determine salinity tolerance and aquaculture potential of squawfish in this water. Lethal salinity to 50 percent of the fish (96 h LC50) was 13.1 g l?1, indicating that squawfish survival in higher salinity spring water was not possible. Published in Hydrobiologia, volume 657, in 1992.

The whooping crane (Grus americana) is a listed, endangered species in North America, protected under federal legislation in the United States and Canada. The only self-sustaining and wild population of Whooping Cranes nests at and near Wood Buffalo National Park near the provincial border of Northwest Territories and Alberta, Canada. Birds from this population migrate through the Great Plains of North America and spend a nonbreeding period along the Gulf Coast of Texas at Aransas National Wildlife Refuge and surrounding lands. These data represent predictions from a resource selection function using GPS locations between 2010 and 2016 during migration. This surface is a composite of drought and non-drought conditions...

Data presented are results of surveys for California gnatcatchers and vegetation sampling conducted in 2015, 2016, and 2020 to address two inter-related questions: (1) How have gnatcatchers and their habitat recovered in areas burned by wildfires in 2003, 2007, and 2014?, and (2) What is the current regional occupancy of gnatcatchers throughout their southern California range? Data for the post-fire study were collected in 2015, 2016, and 2020, while the regional occupancy survey was conducted in 2016, and 2020. In 2015, gnatcatcher occupancy as a function of fire history was derived from 324 points in the following fire categories: 2003-2006 (106 points), 2007-2010 (111 points), and 2011-2014 (107 points). In 2016,...

This project has two goals: Goal 1: The goal of this project is to conduct a statistically rigorous study of occupancy to determine the post-fire recovery of gnatcatchers and coastal sage scrub vegetation with the goal of informing management before, during, and after fire. Goal 2: The goal of this project is to conduct rangewide surveys to determine California Gnatcatcher occupancy at a regional scale. Because California Gnatcatchers will be managed through management of coastal sage scrub rather than through species-specific actions, it is necessary to determine the current status of gnatcatchers on protected lands in southern California to understand how gnatcatcher occupancy is related to coastal sage scrub...

Data presented are results of surveys and monitoring in 2019 for Southwestern Willow Flycatcher (Empidonax traillii extimus) in San Diego County, California. Surveys were conducted at locations along Cottonwood Creek, Tijuana River, and the San Luis Rey River, and nest monitoring was performed at three locations along the San Luis Rey River downstream of Lake Henshaw (Cleveland National Forest, Rey River Ranch, Vista Irrigation District). Surveys were conducted along multiple sections of the river where permission to access properties could be obtained. Locations were surveyed using a standardized protocol three to four times between 15 May and 31 July. The number, age (adult or juvenile), sex, banding status (color...

The Yukon–Kuskokwim Delta of Alaska,USAis a globally important region for numerous avianspecies including millions of migrating and nesting waterbirds.However, data on the current spatial distributionof critical nesting areas and the importance of environmental variables in the selection of nest locations aregenerally lacking for waterbirds in this region.We modeled nest densities for 6 species of geese and eiders thatcommonly breed on the Yukon–Kuskokwim Delta, including cackling goose (Branta hutchinsii minima),emperor goose (Chen canagica), black brant (B. bernicla nigricans), greater white-fronted goose (Anser albifronsfrontalis), spectacled eider (Somateria fischeri), and common eider (S. mollissima).Thedata...

Broadly, recovery of threatened and endangered species requires specific management actions by natural resource managers at a fine scale. We used a systematic conservation planning framework to outline conservation goals across multiple land-uses, including native habitat protection and identifying endangered species-specific recovery areas while minimizing intrusion on existing hunting areas on the island of Lanai. We used spatial prioritization tools to generate multiple scenarios where both conservation and hunting areas (deemed zones for analysis purposes) were delineated to meet land-use goals. These delineated areas will help land managers to minimize conflicts between uses for populations of non-native game...
Hawaiian hoary bats ('ōpe'ape'a; Lasiurus semotus) were captured and tracked back to roosting locations on Hawaiʻi Island. Roost perch metrics were observed and collected from 2019 to 2021. We observed a total of 69 perches used by 52 bats (16 female; 22 male; 14 unknown) within 44 roost trees. This data file includes data pertaining to roost perch locations, dates, height, canopy cover, and aspect.
Hawaiian hoary bats ('ōpe'ape'a; Lasiurus semotus) were captured and tracked back to roosting locations on Hawaiʻi Island. Roost tree metrics were measured and collected from 2018 to 2021. We observed a total of 56 roost trees used by 46 bats (18 female; 25 male; 3 unknown). This data file includes data pertaining to roost tree metrics including, height, diameter at breast height (DBH), tree species, canopy cover, and habitat classification.

Predation and habitat degradation by non-native species are principal terrestrial threats to the federally endangered Hawaiian Petrel (ʻuaʻu, Pterodroma sandwichensis) and Hawaiian Goose (nēnē, Branta sandvicensis) within Haleakalā National Park (HALE), Maui, Hawaiʻi. Since 1981, HALE has maintained a network of live-traps to control invasive mammalian predators and protect these endangered birds. To continue evaluations of trapping efficiency in HALE, we analyzed 2000 - 2014 trap events. Trap events were divided up into six event types classified into three event categories: no event, other event [bait lost, or trap triggered], or predator event [rat, cat, or mongoose caught]. Event type analysis was divided up...

We present two tabular digital data files representing values related how the presence of hetero- and conspecifics influence nest and chick survival for two listed migratory species breeding on the Missouri River; piping plover (Charadrius melodus) and least tern (Sternula antillarum). We followed 2,507 piping plover nests, 3,251 uniquely banded piping plover chicks, 1,060 least tern nests, and 1,377 uniquely banded least tern chicks from 2007 - 2009, 2012- 2016 in the Northern Great Plains of the US. This included river and reservoir habitats present on the Missouri River in North and South Dakota. Not all study areas were studied in all years. The nest survival dataset includes values for use with the Shaffer...
