Oregon Greater Sage-Grouse Population Monitoring: 2017 Annual Report

Creator:: Foster, Lee
Abstract:: During the 2017 greater sage-grouse (Centrocercus urophasianus) breeding season, 1,580 aerial and ground lek surveys were conducted at 674 individual lek sites comprising 429 lek complexes. Surveys were conducted at 58.0% of known lek sites in the state. Survey effort during 2017 declined -17.1%, -12.2%, and 14.5% from 2016 levels,...

Oregon Greater Sage-Grouse Spring Population Monitoring: 2016 Annual Report

Creator:: Foster, Lee
Abstract:: During the 2016 greater sage-grouse breeding season, 1,908 aerial and ground lek surveys were conducted at 768 individual lek sites comprising 501 lek complexes. Surveys were conducted at 66.0% of known lek sites in the state, which was the greatest proportion of leks ever surveyed in Oregon. Survey effort during...

Greater Sage-grouse conservation assessment and strategy for Oregon: A plan to maintain and enhance populations and habitat

Creator:: Hagen, Christian
Abstract:: Greater sage-grouse (Centrocercus urophasianus) were once found in most grassland and sagebrush (Artemisia spp.) habitats east of the Cascades in Oregon. European settlement and conversion of sagebrush steppe into agricultural production led to extirpation of the species in the Columbia Basin by the early part of the 1900s, but sagebrush...

Artificial means of distinguishing smooth-line map unit boundaries : an examination of Oregon soil survey maps

Creator:: Sun, Yulin
Abstract:: Soil is a complex living system with high heterogeneity, which makes locating soil map boundaries a challenge. In traditional soil survey, the placement of soil map boundaries relies largely (at least initially) on identifying the soil-forming factors of biota and topographic relief through stereo aerial photo pairs. Future soil survey...

A preliminary assessment of hydrogeologic suitability for Aquifer Storage and Recovery (ASR) in Oregon

Creator:: Woody, Jen
Abstract:: An ASR metric and site rating index applied to over 120 municipal and agricultural locations across Oregon, combined with comparison to case study data from existing ASR sites, indicate that more than 50% of selected sites are hydrogeologically suitable for ASR. The ASR metric is a ratio of aquifer storage...

Post-dispersal seed fates in a Western Oregon native prairie

Creator:: Clark, Deborah L.
Abstract:: Knowledge of post-dispersal seed fates and other regeneration characteristics is crucial for predicting abundances and distributions of populations and, ultimately, community species composition and diversity. Seed fate studies, however, are rare primarily due to the difficulty of determining seed fates and causes of mortality. This thesis investigated post-dispersal seed fates...
