Natasha B Carr, PhD
Natasha Carr is a Scientist Emeritus at the Fort Collins Science Center. Natasha's research interests include applications of landscape, community, and fire ecology to multiscale land management issues.
Natasha Carr began as a research scientist with the US Fish and Wildlife Service in 1990 and converted to the U.S. Geological Survey in 1994. Her research interests include applications of landscape, community, and fire ecology to multiscale land management issues. A key component of her work includes developing science applications and practical tools for natural resource managers and policy makers. Current projects include developing innovative approaches for conducting broad-scale assessments and streamlining the NEPA process. Since 1986, she has authored or coauthored over 50 publications and associated USGS datasets.

Green-tailed Towhee response to prescribed fire in montane shrubland
Fire alters the structure and composition of shrublands and affects habitat quality for the associated avifauna. Because shrubland ecosystems have been greatly reduced from their original extent in western North America and fire is increasingly being used to manage these landscapes, a better understanding of how fire affects the associated vegetation and wildlife is imperative. We evaluated the reAuthorsG. Jehle, J. A. Savidge, N.B. KotliarVariation in fire regimes of the rocky mountains: Implications for avian communities and fire management
Information about avian responses to fire in the U.S. Rocky Mountains is based solely on studies of crown fires. However, fire management in this region is based primarily on studies of low-elevation ponderosa pine (Pinus ponderosa) forests maintained largely by frequent understory fires. In contrast to both of these trends, most Rocky Mountain forests are subject to mixed severity fire regimes. AAuthorsV.A. Saab, Hugo D. W. Powell, N.B. Kotliar, K.R. NewlonIntegrated fire science in the Rocky Mountains
Fire is an important ecological process that has helped shape western landscapes. Wildfire suppression and other management practices may have altered historic fire regimes in ecosystems adapted to frequent, low-severity fires. Compounding this problem is the encroachment of homes into fire-prone areas. Fire affects a number of abiotic and biotic components of ecosystems, and had many economic andAuthorsNatasha B. KotliarLessons from the fires of 2000: Post-fire heterogeneity in ponderosa pine forests
We evaluate burn-severity patterns for six burns that occurred in the southern Rocky Mountains and the Colorado Plateau in 2000. We compare the results of two data sources: Burned Area Rehabilitations Teams (BAER) and a spatial burnseverity model derived from satellite imagery (the Normalized Burn Ratio; NBR). BAER maps tended to overestimate area of severe burns and underestimate area of moderateAuthorsNatasha B. Kotliar, Sandra L. Haire, Carl H. KeyEffects of fire and post-fire salvage logging on avian communities in conifer-dominated forests of the western United States
Historically, fire was one of the most widespread natural disturbances in the western United States. More recently, however, significant anthropogenic activities, especially fire suppression and silvicultural practices, have altered fire regimes; as a result, landscapes and associated communities have changed as well. Herein, we review current knowledge of how fire and post-fire salvaging practiceAuthorsN.B. Kotliar, S.J. Hejl, R.L. Hutto, V.A. Saab, Cynthia Melcher, M.E. McFadzenApplication of the new keystone-species concept to prairie dogs: How well does it work?
It has been suggested that the keystone-species concept should be dropped from ecology and conservation, primarily because the concept is poorly defined. This prompted Power et al. (1996) to refine the definition: keystone species have large effects on community structure or ecosystem function (i.e., high overall importance), and this effect should be large relative to abundance (i.e., high communAuthorsN.B. KotliarMultiple scales of patchiness and patch structure: a hierarchical framework for the study of heterogeneity
We develop a hierarchical model of heterogeneity that provides a framework for classifying patch structure across a range of scales. Patches at lower levels in the hierarchy are more simplistic and correspond to the traditional view of patches. At levels approaching the upper bounds of the hierarchy the internal structure becomes more heterogeneous and boundaries more ambiguous. At each level in tAuthorsNatasha B. Kotliar, John A. WiensColony site selection and abandonment by least terns Sterna antillarum in New Jersey, USA
To develop habitat and management procedures to protect declining populations of least terns, colony site selection and abandonment by this species was investigated at 26 sites in New Jersey. Multivariate analysis was used to compare (1) colony sites to adjacent unused areas, (2) those located on beaches to dredge spoil sites and (3) abandoned to occupied colony sites.
