A Bit About Us...

Thomas P. Henn, M.S.
(Tom sometimes helps with projects when he has time.)
We have done consulting work, mainly botanical surveys (threatened, endangered, sensitive, wetland and invasive plant species), and Kali has recently worked on ethnobotany/traditional cultural plant projects related to Native American tribes of the Pacific Northwest. A few years ago Kali spent quite a bit of time writing an encyclopedia, and Tom now works for the City of Portland Parks. We operated our small nursery and didn't have much time left for consulting or surveying, but the nursery is now phased out, and Kali has returned to consulting. If you are looking for assistance with botanical projects, including ethnobotany, restoration advice, surveys, or training, check out some of our past projects, below and resumes, above. Kali has extensive botanical expertise and teaching experience. She has worked with several Native American tribes in the Pacific Northwest.
As a contractor or subcontractor to larger environmental contractors, Kali can help you:
-Conduct botanical surveys and ensure plants are correctly identified.
-Develop a diverse plant palette for restoration projects, with the proper native species installed in appropriate habitats.
-Monitor restoration projects to evaluate success.
-Gather data on plant communities of interest, including running transects and quantifying percent cover for species present; analyzing and interpreting results.
-Present results and conclusions in reports and presentations.
-Conduct background research, including taxonomy, status and habitat, on species of interest.
Robson Botanical Consultants provides surveys and taxonomic identification of threatened, endangered and sensitive plants, plants of traditional cultural importance to Native American Tribes of the Pacific Northwest, in addition to exotic or noxious species, wetland plants, bryophytes and lichens for NEPA compliance/biological evaluations, traditional plant studies, plant community quantification and wetlands delineations. We perform surveys, monitoring, data collection, analysis, interpretation and reporting on plant communities or species of special interest.
Robson Botanical Consultants also offers seminars on landscaping with PNW natives (based on Encyclopedia of Northwest Native Plants for Gardens and Landscapes), and re-vegetation recommendations for riparian, wetland or upland restoration projects. We have worked with private homeowners as well as government and commercial clients in surveying, reporting and assisting with planting designs for improved wildlife habitat, wetland mitigation and environmental remediation. Now that the nursery is history, Kali is moving back to contracting and consulting, and is especially interested in traditional cultural/ethnobotanical projects, such as those described below.
In addition to a variety of homeowners, our clients have included:
- Colville Confederated Tribes History/Archaeology Program - launching Traditional Cultural Plant Program - Kali agreed to work on this project as a temporary hire in order to help the Tribal Plant Team start botanical surveys and develop a new herbarium. In our preliminary survey of the Colville Reservation, we located, documented, collected and preserved many plants of traditional cultural use as foods, medicines, building materials and more. We recorded habitat characteristics for each species of interest, including infestations of noxious weeds and other impacts that could negatively impact populations of these important native plants. Plans for the future include additional surveys and more detailed quantification and analysis of the vegetation, 2013 - 2014
- Army Corps of Engineers, Walla Walla District - Traditional Plant Study- Robson Botanical Consultants was subcontractor to Mangi Environmental Group along with an ethnography consultant from ASM Affiliates. We produced a report on 50 plants most likely to be of high value to the Native American tribes in the areas managed by the Walla Walla District, including the Lower Snake River in Washington, the area around Dworshak Reservoir in northern Idaho, and the vicinity of Lucky Peak Dam, near Boise ID. The study included a description of each species, its habitat and traditional uses. The Mangi GIS team developed map layers of probable habitat for each plant, based on available information, 2012
