Reproductive Success and Brood Habitat Use of Greater Prairie Chickens and Sharp-Tailed Grouse on the Fort Pierre National Grassland of Central South Dakota
… have remained stable. Survival, reproduction and habitat use data from these populations provide insight to important variables contributing to the dynamics and management of the populations on the Fort Pierre National Grassland (FPNG). Additionally, these data may shed light on efforts to …

Field evaluation of the northern bobwhite habitat suitability index model with implications for the conservation reserve program
… of the northern bobwhite (Colinus virginianus) Habitat Suitability Index (HSI) model was conducted using habitat and relative abundance data from 121 sites distributed throughout Halifax County, Virginia, 1986-1991. Model output and the index of relative abundance were only poorly correlated …

Habitat Preferences and Censusing of Waterfowl Broods On Stock Ponds In South Central South Dakota
Waterfowl broods on stock ponds in south central South Dakota were surveyed in 1977 and 1978 to compare flush and observation techniques for censusing broods and to determine waterfowl brood habitat preferences. Results indicated that 72-8% of the broods present were censused by either technique …

Movements and Habitats of Brood-Rearing Wood Ducks On A Prairie River
Radio telemetry and brood surveys were used to evaluate wood duck (Aix sponsa) brood habitat and movements along 40 km of the Big Sioux River in eastern South Dakota during 1979-81. Most of the oxbows and nearby wetlands in the study area contained water in 1979-80, but drought dried all but 2 of …

Use and Survival of Greater Sage-Grouse in Meadows Managed for Non-Native Ungulate Grazing in Nevada
… been attributed to extensive loss of sagebrush habitat. Consequently, investigating how disturbance to seasonal sagebrush habitat, such as winter and nesting habitat, affects population dynamics of sage-grouse has been a major focus of research. However, low juvenile survival and recruitment has …

Ruffed grouse (Bonasa umbellus) habitat ecology in the central and southern Appalachians
… low in Appalachian forests, possibly because low habitat quality negatively affects survival, condition, and reproduction. Through the Appalachian Cooperative Grouse Research Project (ACGRP) researchers tracked >1500 radioed grouse at 10 study sites (1996__2002). To improve our understanding of …

Factors limiting piping plover nesting pair density and reproductive output on Long Island, New York
Storm-created nesting habitat and low wave energy moist sediment habitat (MOSH), such as intertidal sandflats, have long been considered important to the recovery of the piping plover (Charadrius melodus), a federally threatened shorebird. Beach renourishment is a common practice on the U.S. …

Relative Invertebrate Availability in Nebraska's Conservation Reserve Management Access Program
… Forever of Nebraska that seeks to address brood habitat needs of pheasants (Phasianus colchicus) and other grassland birds by light disking and interseeding legumes into portions of aging CRP fields. The program has two specific goals - increasing the total invertebrate availability as a …

Ecology of Merriam's Turkeys in the Southern Black Hills, South Dakota
… (P = 0.70) from females that wintered in forest habitats. Turkeys selected for open to mid-canopy (0-70%) mature (>22.9 cm diameter at breast height [DBH]) structural stage pine stands for feeding sites. During the hunting period, gobbling activity was lower (P = 0.001) in a hunted population …

Ruffed grouse natality, chick survival, and brood micro-habitat selection in the southern Appalachians
… to 0.32 in 1997 and 0.45 to 0.48 in 1998. Late brood season survivorship values (0.11-0.13 at week 5, 0.07 at week 10) were considerably lower in the southern Appalachians than those reported from more northern portions of ruffed grouse range. Additionally, the mean number of chicks per brood in …
