These data provide the locations and phenological dates of three shrub species: beaked hazelnut (Corylus cornuta), Oregon grape (Mahonia aquifolium), and salal (Gaultheria shallon), collected from various publicly available data sources including data from USFS Forest Inventory and Analysis program, USFS R-6 Ecology Program, US National Park Service, USDI Bureau of Land Management, USA National Phenology Network, the Consortium of PNW Herbaria, the Wilbur L. Bluhm Plant Phenology Study, GBIF, and iNaturalist, as well phenology data collected from the Olympia Forestry Sciences Laboratory in Olympia, Washington.

These data provide current and future projected habitat distribution models for four shrub species: beaked hazelnut (Corylus cornuta), Oregon grape (Mahonia aquifolium), salal (Gaultheria shallon), and black huckleberry, (Vaccinium membranaceum), as well as a current projected habitat distribution model for evergreen huckleberry (Vaccinium ovatum). Each raster file represents the projected habitat suitability for each shrub species, climate scenario, and time period. Files are named according to the species (coco = Corylus cornuta, maaq = Mahonia aquifolium, gash = Gaultheria shallon, vame = Vaccinium membranaceum, and vaov2 = Vaccinium ovatum), then the RCP pathway (none for current, 'low' for RCP 4.5, and 'high'...
Riparian plant communities are shaped by gradients of disturbance intensity and frequency and resource availability. Reservoir operation can alter the composition and abundance of riparian vegetation by changing the flood regime and by trapping fine sediments and associated nutrients within the reservoir system. We examined differences in herbaceous species richness, abundance and composition in Populus-Salix stands along an unregulated and regulated reach of a river in semi-arid Arizona, contrasted flood inundation frequency and edaphic conditions (soil moisture, nutrients and texture) between the reaches, and interpreted the vegetation differences in light of observed differences in environmental conditions. Flooding...
