I hold an MS in watershed hydrology and a BS in botany, with additional course work in mined land reclamation.  I was an environmental consultant for 22 years specializing in wetlands ecology, soil science, physical habitat, habitat restoration, T&E recovery work, and NEPA documentation.  More recently, I served as the Natural Resources Manager for a western Washington county.  Currently, I serve as Water Resources Program Manager for the Nooksack Indian Tribe near Bellingham, WA. I am particularly interested in the effect of climate change on glacier ablation and recession as it relates to the reduction of sustaining flows for spring Chinook salmon in the Nooksack River.

I am an ecosystems ecologist specializing in natural resource conservation and restoration.  My focus is on integrating conservation and restoration practices in a manner that provides real benefit to glocal (global-local) community with a range of ecosystem functions and services.
