Forest carbon (C) density varies tremendously across space due to the inherent heterogeneity of forest ecosystems. Variation of forest C density is especially pronounced in mountainous terrain, where environmental gradients are compressed and vary at multiple spatial scales. Additionally, the influence of environmental gradients may vary with forest age and...

Armyworm caterpillars can be a troublesome pest in cereal grains grown in the Pacific Northwest states. This publication presents information about the pest and its control.
The wheat head armyworm (Faronta diffusa) is a troublesome pest in cereal grains in the Pacific Northwest. This publication describes the life cycle, behavior, distribution, and feeding of the wheat head armyworm. Guidance on identification and control of the pest is also provided.
Colony size, nesting ecology and diet of Caspian Terns (Hydroprogne caspia) were investigated in the San Francisco Bay area (SFBA) during 2003-2009 to assess the potential for conservation of the tern breeding population and possible negative effects of predation on survival of juvenile salmonids (Oncorhynchus spp.). Numbers of breeding Caspian...
Monitoring unstable slopes with terrestrial laser scanning (TLS) has been proven effective. However, end users still struggle immensely with the efficient processing, analysis, and interpretation of the massive and complex TLS datasets. Two recent advances described in this paper now improve the ability to work with TLS data acquired on...
