Second generation knowledge based systems in habitat evaluation.
… of ecology, several of which are concerned with habitat evaluation. However, these systems have been geared to solving particular problems, with little regard paid to the underlying relationships that exist within a biological system. The implementation of problem-solving methods with little …

Wildlife Habitat Evaluation of the Unchannelized Missouri River in South Dakota
<p>Areas of eight habitats were identified, delineated, and measured along the unchannelized Missouri River in South Dakota. Agricultural and urban developments existed on 60 percent of the land within 1 km of the river. Six habitat types made up the non-developed land in the study area: …

Habitat evaluation and production of rock bass in two Virginia streams
The use of Habitat Suitability Index (HSI) models for fisheries impact assessment has not been field validated for most fish species. This research sought to test several of the fundamental assumptions inherent in applications of Suitability Index (SI) curves with the Habitat Evaluation Procedures …

Development of a Predictive Habitat Evaluation Model for Gaillardia Aestivalis (Walt.) Rock. Var. Winkleri (Cory) Turner Using GPS, Remote Sensing and GIS Techniques
… characterize and subsequently predict potential habitat of Gaillardia aestivalis var. Winkleri, occurring in Hardin County, TX. Field investigations along with CIR positive aerial photographs were used to study local distribution and ecological requirements (soil, site, plant associations) of the …

Determining the Suitability of Functional Landscapes and Wildlife Corridors Utilizing Conservation GIS Methods in Denton County, Texas.
… which accelerated the loss and removal of native habitat and wildlife. This research sought out to identify the remaining natural areas which retain their natural features and support wildlife. Research methodology included fundamental principles of Conservation Planning, Geographical Information …

Breeding bird populations in relation to the vegetation structure of abandoned contour mines in Southwest Virginia
… and total study areas are presented for use in habitat evaluation. Relationships revealed for bird population parameters of the disturbed and total study areas suggest that reclamation efforts should strive to achieve a high degree of vegetative cover, increase the amount of ground layer …

Landscape pattern analysis related to forest wildlife resources
… There was evidence that spatial scale influences habitat evaluation. Semivariogram analysis assessed the constancy of expression behavior during changes in scale and presented the limits of tolerance for using large pixels in pattern analyses. The variability observed suggested that pattern …

A Gis-Based Habitat Model Predicting Elk Nutritional Condition in the Pacific Northwest
"Declining habitat quality has been implicated in population declines in elk (Cervus elaphus) in the Pacific Northwest (PNW) although specific causes are unknown. Nutrition and summer-autumn body condition (percent body fat) have been linked to virtually every aspect of successful ungulate …
