Bird-habitat relationships in the shrubsteppe of Hanford National Monument
Entry ID: USGS_FRESC-464_Hanford_Avian_Habitat

[ Update this Record ]

Abstract: The Excel spreadsheet contains data from 318 point-count locations, including abundance of 8 focal avian species, field measurements of vegetative characteristics, and key cover type characteristics derived from remotely-sensed data. All point-count locations were within the Hanford Reach National Monument in southeastern Washington.

Purpose: Data were collected to examine avian abundance in relation to shrubsteppe habitat characteristics, specifically whether avian abundance differed in bunchgrass or cheatgrass understory and whether both remotely-sensed and field-acquired measures of big sagebrush were valuable in understanding avian abundance.

Quality Attribute_Accuracy:
In preliminary analyses, we used the program Distance with the hazard-rate detection function and found that the probability of detection was high for the eight focal species within a 100-m radius. Thus, in the bird–habitat analysis presented here, we use only observations ... View entire text
Access Constraints Please contact Susan Earnst for access to the data
Use Constraints The point count data should be interpreted as relative abundance data. The observations have not been corrected for detection probabilities. Relative abundance is an appropriate metric for modeling habitat preference, which is the purpose of this data set. Please contact Susan Earnst with questions if the data are to be used for other purposes.
