This dataset depicts winter recreation sites located on the Mt. Hood and Willamette National Forests. The point locations and associated attributes were derived from the recreation opportunity information that the Forest Service collects through the Recreation Portal and shares with the public on http://ww.recreation.gov, the Forest Service World Wide Web pages (http://ww.fs.fed.us/) and the Interactive Visitor Map. Only those recreation sites with associated winter activities were retained in this dataset.

This data contains basic attributes to describe the recreation area name and unit location. This dataset was derived by copying the developed recreation boundaries stored within each Forests' corporate recreation GIS dataset.

Data are the result of fixed-area, time-constrained searches for terrestrial salamanders within and nearby a wildfire-affected area of the Willamette National Forest, OR. The spatial extent of the study was within one kilometer of the border of the Clark fire that burned an area of 2,009 ha in 2003. Site surveys occurred during March and April, 2005. An important feature of the data is that 100m2 sub-plots (nested within plots) were repeatedly searched for terrestrial salamanders independently up to nine times so that variation in the probability of capture could be estimated and accounted for concurrent with estimates of occupancy probability.

This dataset depicts commercially used river segments located on the Mt. Hood and Willamette National Forests. The dataset was derived by identifitying upper and lower river launch sites. The national hydrography dataset was used as the source for mapping the associated river segments.
