Abstract

Populations of Henslow's Sparrows (Ammodramus henslowii) arc declining, and loss of habitat is a likely factor. Coal mine reclamation has created grassland habitat in Kentucky and elsewhere, and information is needed concerning the use of these areas by Henslow's Sparrows. We compared the behavior and ecology of populations on reclaimed sites and non-mined sites in west-central Kentucky during the 2000 and 2001 breeding seasons. Territories were smaller on the reclaimed sites than unmined sites, perhaps due to differences in habitat quality. Insect sweeps revealed more prey biomass on reclaimed sites than unmined sites. Twenty-eight of 48 nests (58%) fledged at least one young, and nesting success was similar on reclaimed and unmined sites. Mean clutch size was 3.75, with no difference between reclaimed and unmined sites. Similarly, the mean number of fledglings per nest was similar on reclaimed and unmined sites. Multivariate analysis revealed differences in the characteristics of vegetation on reclaimed areas and unmined areas. Reclaimed areas had more grass cover and greater vegetation density, probably due to differences in management history (i.e., mowing or burning) and species composition. Our results indicate that the nesting success of Henslow's Sparrows on reclaimed surface mines in Kentucky is comparable to thatmore »« less

Analysis of the habitat of Henslow's sparrows and Grasshopper sparrows compared to random grassland areas

Journal Article Maier, Kristen; Walton, Rod; Kasper, Peter

Henslow's Sparrows are endangered prairie birds, and Grasshopper Sparrows are considered rare prairie birds. Both of these birds were abundant in Illinois, but their populations have been declining due to loss of the grasslands. This begins an ongoing study of the birds habitat so Fermilab can develop a land management plan for the Henslow's and Grasshoppers. The Henslow's were found at ten sites and Grasshoppers at eight sites. Once the birds were located, the vegetation at their sites was studied. Measurements of the maximum plant height, average plant height, and duff height were taken and estimates of the percent ofmore »« less

Nesting success of grassland and savanna birds on reclaimed surface coal mines of the midwestern United States

Journal Article Galligan, E; DeVault, T; Lima, S - Wilson Journal of Ornithology

Reclaimed surface coal mines in southwestern Indiana support many grassland and shrub/savanna bird species of conservation concern. We examined the nesting success of birds on these reclaimed mines to assess whether such 'unnatural' places represent productive breeding habitats for such species. We established eight study sites on two large, grassland-dominated mines in southwestern Indiana and classified them into three categories (open grassland, shrub/savanna, and a mixture of grassland and shrub/savanna) based on broad vegetation and landscape characteristics. During the 1999 and 2000 breeding seasons, we found and monitored 911 nests of 31 species. Daily nest survival for the most commonlymore »« less

GRASSLAND BIRD DISTRIBUTION AND RAPTOR FLIGHT PATTERNS IN THE COMPETITIVE RENEWABLE ENERGY ZONES OF THE TEXAS PANHANDLE

Technical Report Jansen, Erik

The consistent wind resource in the Great Plains of North America has encouraged the development of wind energy facilities across this region. In the Texas Panhandle, a high quality wind resource is only one factor that has led to the expansion of wind energy development. Other factors include federal tax incentives and the availability of subsidies. Moreover, the State Renewable Portfolio Standards (RPS), mandating production of 10,000 mega-watts of renewable energy in the state by 2025, has contributed to an amicable regulatory and permitting environment (State Energy Conservation Office 2010). Considering the current rate of development, the RPS will bemore »« less
Comparison of avian populations on unmined and reclaimed lands in Illinois

Conference Sponsler, M; Klimstra, W - Univ. Ky., Off. Eng. Serv., (Bull.); (United States)

Avian populations were sampled in southwestern and west central Illinois on mined and unmined and reclaimed lands to evaluate the impact on these populations of the reclamation required by the Illinois Surface-Mined Land Reclamation and Conservation Act of 1971. Comparison of avifauna of each habitat type showed reclaimed lands held more individuals than the unmined fence row, cropland, oldfield and woodland; less density was noted on mined sites as compared to unmined hedge row, pond, streamside pasture, and edge habitats. Avian diversity indices on reclaimed land were lower than every unmined habitat type; however, reclaimed land populations appeared to bemore »« less
