Bird and Spatial Datasets

Here we provide selected datasets and links to datasets relevant to the monitoring, modeling, and management of landbird populations in the Pacific Northwest. A Google Earth dataset is provided to map the network of 36 MAPS monitoring stations.

Breeding Bird Survey Trend Analyses: A multi-sheet Microsoft Excel spreadsheet in which BBS populations trends and landbird conservation plans are reported for all species in four regions - Willamette Lowlands, Northern Pacific Rainforest, Southern Pacific Rainforest, and Columbia Plateau. These trends were estimated over a time period in which Region 6 MAPS data were collected and analyzed (1992-2006). We also provide a tool which permits BBS trend estimation in which you can select the first and last year, multiple species, and multiple regions. www.birdpop.net/scripts/trend07.php

MAPS Datasets: MAPS data may be obtained from IBP in a manner consistent with the IBP Data Policy.

GIS Layers: These GIS layers were used in the construction of the species-landscape models (Nott and Michel 2005) and include layers relating to MAPS stations and their surrounding landscapes, and spatial statistics thereof. Regional-scale layers provide data on elevation, land cover, streams, forest canopy cover, and forest health.

Sources of layers used in Nott and Michel (2005) are listed below. The portions used in the project can be obtained on CD from IBP. Contact Phil Nott, Box 1346, Poiint Reyes Station, CA 94956. E-mail: pnott@birdpop.org
