We collected detailed spatial data on the density and size distribution of intertidal snails as part of a broader effort to understand food webs in California estuaries. The survey area was Carpinteria Salt Marsh, California USA, which comprises 9 Ha tidal channels, 2 Ha salt flats, 17 Ha upland habitat, 6 Ha tidal pans, 52 Ha vegetated marsh, 2 Ha tidal flats. Using nearly 4,000 transects in potential snail habitat, we mapped snails throughout the estuary. Specifically, we systematically placed transects at intervals stratified within targeted habitat types: channels, pans, or marsh (or planar habitat that was mixed marsh and pan). At a quarter of the quadrats, we also estimated snail size-frequency distributions....
Habitat valuation methods are most often developed and used to prioritize candidate lands for conservation. In this study the intent of habitat valuation was to inform was to inform the decision-making process for remediation of chemical contaminants on specific lands or surface water bodies. Methods were developed to summarize dimensions of habitat value for six representative aquatic and terrestrial contaminated sites at the East Tennessee Technology Park (ETTP) on the US Department of Energy Oak Ridge Reservation in Oak Ridge, TN, USA. Several general valuation metrics were developed for three broad categories; site use by groups of organisms, site rarity, and use value added from spatial context. Examples of...

This project would increase diversity of forbs and invertebrates in riparian and transitional riparian/upland areas through mowing and seeding of native forb species. A tractor powered mower with a seeder would be used to create an enhanced vegetative mosaic within riparian or transitional riparian areas lacking in vegetative species and structural diversity. A contractor would provide a tractor or seeder for distribution of native seed. This project would focus on improving habitat for a diversity of species, particularly sage grouse and other BLM sensitive avian species such as the Brewer's sparrow and sage thrasher, which rely on riparian habitats for critical brood rearing requirements in the Sand Hills ACEC...

This project will provide for deer crossing the Baggs highway (789) to reduce vehicle collisions. Construction of 3-4 miles of deer proof fence to funnel a portion of a migrating deer herd to existing culvert under HWY 789 to reduce deer vehicle collissions. Installation of 6 cattleguards in current access points to prevent deer access through fences at these points. Further, the project would cover several years and work toward providing safe wildlife passage. Industry and WDOT are being approached to partner with the WGFD on this project. Providing deer crossings of HWY 789 will reduce the incidences of vehicle and deer collisions, reducing deer mortality and damage to vehicles. The project would be done in a...

This publication provides the most complete information available on the status of rare vertebrate species and vascular plant species in Wyoming. It updates and replaces previous lists (Fertig and Beauvais 1999, Fertig and Heidel 2002), and documents 473 plants and 125 vertebrates of conservation and management concern in Wyoming. For each species, a summary of factors used in weighing species’ status including distribution, abundance, trends, and intrinsic vulnerability, is also provided. Interest in rare species has increased substantially over the past 40 years, and currently there is broad support for the conservation of rare plants and animals in North America. Natural resource managers, policy makers, and...

Prescribed burns to restore aspen habitat on one of the most important elk calving areas for Afton herd and important for aspen-dependent species, transition and winter range for elk, mule deer, and moose east of Alpine, transition and winter range for mule deer and elk of crucial winter range just east of Smoot, and sagebrush, aspen, meadow, and willow habitat on transition range for mule deer and elk 30 miles up the Greys River. In addition, determine 1) locations and distribution of aspen stands on the district that are in need of treatment and 2) prioritize stands relative to level of risk, this information to be used in formulating an aspen treatment schedule. (This assessment would be consistent with methodology...
Approximately 298 acres of seasonal shallow water wetland habitat will be established or enhanced for water birds and waterfowl by constructing and repairing low level dikes and installing 6 water control structures. In addition, permanent water wetlands will be constructed enhance the wetland complex.

Project Synopsis: the Ferris Mountain project area consists of mainly timbered slopes, interspersed with upland areas dominated by sagebrush, grass, and mountain shrub communities. Timber stands within the project unit consist of Douglas fir, subalpine fir, spruce, lodgepole pine, limber pine, and aspen, in addition to scattered locations of Rocky Mountain juniper. Long-term suppression of wildfires has promoted the encroachment of conifers into shrublands, aspen stands, and drainages supporting aspen, waterbirch and willows, to the point where many of these communities are non-functional. Decadence and disease is commonly observed in terms of mistletoe, blister rust, and bleeding rust, and pine beetles have...
Our demands on natural systems outweigh the capacity of those systems to support us. This paper calls for an approach to development that consistently delivers ‘net benefit’ for biodiversity or ‘ecological enhancement’. Examples of enhancement are presented through four case studies in India undertaken between 2005 and 2010. Actions focus on improving the overall ecological structure, composition and functions of sites; strengthening ecological networks by creating new habitats and buffer areas; and improving the services provided by the ecosystems, without jeopardizing biodiversity. While recognizing the importance of quantitative metrics of impacts and mitigation measures to determine outcomes, such measures were...

We will develop a set of linked models to help predict the effects of climate change on rivers and endangered species. These will include watershed- and reach-scale models to predict streamflow, water temperatures, and other fish habitat metrics under various climatic scenarios for the reaches used by species listed under the Endangered Species Act (ESA), plus a combined bioenergetics and life-cycle model (to be done by the U.S. Geological Survey [USGS]) to assess the impact of these factors on fish growth, reproduction, and survival. We propose to test the model framework at a site on the Methow River, Washington, to explore additional opportunities for collaboration and model development.
Habitat selection studies can make important contributions to habitat prioritization efforts for species of conservation concern. We present a large-scale collaborative effort to develop habitat selection models for Greater Sage-grouse (Centrocercus urophasianus) across large landscapes (Wyoming, USA) and multiple seasons. Greater Sage-grouse are limited to western semi-arid landscapes in North America, range-wide population declines have been documented, and the species is currently listed a “warranted but precluded” from listing under the U.S. Endangered Species Act. Wyoming is predicted to remain a stronghold for Sage-grouse populations and contains approximately 37% of the remaining birds. We developed Resource...
