This report and especially the accompanying Detail Files and MapFiles provide relatively detailed information on status, trends, distribution, limiting factors, and conservation needs of all of the Willamette’s wildlife species, listed plants, and vulnerable habitats. Data on habitat suitability for each species is provided by watershed (170 HUC6s), elevation (6...
We sought to determine 1) the relationship between seedling
establishment rates of target native prairie species and field
levels of three soil nutrients (phosphate, nitrate, and ammonium)
recorded in fall, winter, and summer, 2) the effect of fire on
these three nutrients, and 3) the overall effect of fire on...
We investigated how large carnivores, herbivores, and plants may be linked to the maintenance of native species biodiversity through trophic
cascades. The extirpation of wolves (Canis lupus) from Yellowstone National Park in the mid-1920s and their reintroduction in 1995 provided the
opportunity to examine the cascading effects of carnivore–herbivore interactions...
