Dataset includes all habitat assessment polygons mapped in Rancho Jamul Ecological Reserve, San Diego County, CA for the South County Grasslands project.Detailed habitat assessments were conducted by CBI, TNC, and SDSU within the four designated South County grassland management planning units (Rancho Jamul Ecological Reserve, Sweetwater Reservoir, Sycamore Canyon, and Proctor Valley) to document existing habitat conditions and determine habitat suitability for target species and habitats. Habitat assessment data were also used to (1) identify suitable resource-specific restoration activities within each of the four planning areas and (2) develop site- and resource-specific Phase II experimental restoration plans....
The influence of the proximity of urbanization and agriculture to stream water quality is often difficult to quantify. The objectives of this study were to (1) compare the influence of far-field land-use, encompassing a watershed drainage area, to a near-field, 200-m buffer on each side of the stream in an attempt to determine on which zone of influence land-use has the largest impact on water quality, and (2) incorporate the EPA's Rapid Habitat Assessment Protocol (Barbour et al., 1999) to characterize the riparian and channel characteristics of a stream that influence water quality, which can improve New York State's monitoring protocols. Impacts were assessed through biological, chemical, and physical-habitat...

A key objective of the Trinity River Restoration Program (TRRP) is maintaining and enhancing other wildlife populations through the restoration initiatives. For herpetological species, the foothill yellow-legged frog and western pond turtle have been identified as important species on which to focus monitoring efforts due to their status as California state-listed Species of Concern. As a result, considerable prior effort has focused on understanding the distribution and demography of these species, both on the main Trinity River and on the South Fork Trinity River as a comparison population (potentially representing pre-dam population status). These studies have highlighted differences in life-history traits of...

The recent proliferation of oil and natural gas energy development in the Greater Green River Basin of southwest Wyoming has accentuated the need to understand wildlife responses to this development. The location and extent of surface disturbance that is created by oil and natural gas well pad scars are key pieces of information used to assess the effects of energy infrastructure on wildlife populations and habitat. A digital database of oil and natural gas pad scars had previously been generated from 1-meter (m) National Agriculture Imagery Program imagery (NAIP) acquired in 2009 for a 7.7-million hectare (ha) (19,026,700 acres) region of southwest Wyoming (Garman and McBeth, 2014). Scars included the pad area...

This dataset includes quantification tools being used or developed for habitat and biodiversity markets in the United States. These tools are designed to estimate the ecological quality or functionality of a site for conservation mechanisms such as payment for ecosystem services programs, eco-label certification programs, habitat exchanges, and conservation banking. The dataset consists of 69 tools which are described using 33 criteria that provide information on the general, technical, and ecological/geographic attributes of each tool.

1985 Gulf of Mexico Atlas abstract American oyster Crassostrea virginica Ostion americanoDescription Range: The American oyster, a bivalve mollusc of the family Ostreidae, is found in the western Atlantic from the Gulf of St. Lawrence to the Yucatan Peninsula. In the Gulf, this species occurs throughout estuaries, shallow nearshore waters, and on reefs located near river mouths. Habitat: Large populations of this benthic invertebrate are found in the large estuarine bays and sounds of the Gulf (with most concentrations found within 10-meter depths). Sedentary in character, this invertebrate attaches in clusters to shell reefs, firm mud/shell bottoms and other hard substrates. Feeding and Behavior: The American oyster...

A new avian richness evaluation method (AREM) was developed and tested for assessing lowland wetland and riparian habitats of the Colorado Plateau. AREM rapidly scores habitats for avian richness from simple observations of habitat characteristics. AREM's predictions were compared with original field data from 76 sites on the Colorado Plateau during the breeding season. Species predictions and detections were highly indicative of the breeding avifauna in regional wetlands studied. AREM has implications for use in mitigation calculations, detection of impaired wetland quality, selection of appropriate indicator species, targeting habitat enhancements, wildlife-based classification of wetland habitats, and assisting...
