The Flora of Beaver County in the Oklahoma Panhandle and the Assembly of Western Great Plains Plant Communities Along a Hydrological Gradient.

Beaver County has the lowest plant collections per area of any county in western Oklahoma, and is located in the understudied shortgrass/mixed-grass prairies of the western Great Plains. The region has a history of high disturbance with a low proportion of protected areas and high risk for climate change induced drought. Through field work and herbarium specimen study, I am documenting a complete list of the vascular plants of the county. 530 plant species have been recorded in Beaver County, and I have developed methods for identifying knowledge gaps in the known flora. Using soil, geological, and hydrological maps, I identified intersections of unique environments as candidates for sampling in the 4700 km2 county. By querying data from other shortgrass and mixed-grass prairie floras, I produced a checklist of likely plants in Beaver County. Thus far, I have documented 20 new county records in one field season. Preliminary Beaver County floristic data was used to test community assembly hypotheses, by analyzing the phylogenetic relatedness of four communities on a hydrological scale from river bottom to upland dune. The relatedness of exotic species in each community was also analyzed to infer how species naturalize along a western Great Plains hydrological gradient and inform management of an economically important and anthropogenically disturbed region.
