EXECUTIVE SUMMARY In 2017, treatments varied by site and establishment of seeded species was low across sites. Overall, soil removal treatments showed the most promise across sites. Soil removal plots had lower cover of invasive grasses and forbs and offered more potential management action(s). Future monitoring will help to elucidate treatment effectiveness and aid in […]
We used non-parametric multiplicative regression (NPMR) to model the effects of climate and environmental variables on flowering of Fritillaria gentneri from 57 sites throughout its range in southern Oregon. We report 4 models using different sites in an attempt to find the strongest predictors for flowering of F. gentneri: In Model 1(51 sites), number […]
This document summarizes monitoring of reintroductions of Kincaid’s lupine in multiple microclimates at three sites in the Willamette Valley, Oregon. Over the years of this study, we have found that seed source and microclimate both affect emergence, survival, and growth (height and number of leaves). Results will inform future management considerations regarding seed transfer zones […]
EXECUTIVE SUMMARY From November 14-17, 2016, we outplanted 2173 individual Bartonberry (Rubus bartonianus) seedlings into 3 locations in Hells Canyon. The sites were located near the Baker and Wallowa County boundary, with the Reservoir and Copper Creek sites adjacent to the Snake River and the Hess Road site located in the Ashby Creek drainage southwest […]
Landward migration zones (“LMZs”) are areas that could become future tidal wetlands under sea level rise. This slideshow explains the methods and results of the Estuary Technical Group’s mapping of potential future tidal wetlands for all the estuaries on Oregon’s outer coast.
This report to the Willamette Valley Native Plant Materials Partnership summarizes actions taken in 2016 in support of production of common native plant species for seed used in restoration in the Willamette Valley. Actions include plant production, seed collection and cleaning, sustainability planning, and partner coordination.
This report to the Bureau of Land Management summarizes actions taken in 2016 in support of seed collection for the BLM’s Seeds of Success Program. All seed collection occurred at time of natural dispersal of common species in mid-elevation prairies in the Cascades foothills east of the Willamette Valley. Actions included scouting for appropriate populations, […]

This report summarizes vegetation monitoring data from before and after a prescribed burn in Fall 2015 at Fitton Green Natural Area, a potential reintroduction site for Taylor’s checkerspot butterfly.
This report to Bureau of Land Management details restoration activities for 2016 for the West Eugene Wetlands Augmentation of Threatened and Endangered Plant Species project, including seed collection, seed and plug production, outplanting, plot maintenance and monitoring.
