Four major variables used in modeling camas habitat suitability: Precipitation, Maximum Temperature, Cost Distance to Known Earth Oven, and Cultural Centrality


In 2013, I wrote an MA thesis at Oregon State University on the distribution of camas (edible plants in the genus Camassia) in the state of Oregon. I used maximum entropy (Maxent) models of camas habitat to measure how much power indigenous cultural geography adds to the model when it is included along with the plant's physical environment. This webpage summarizes that research process. My predictor layers and model outputs are available as a zipped folder for any researchers wishing to replicate my work.

This research project developed over approximately a year and a half. You may trace highlights of this development through the steps below.
