  Citation × Citation Citation Abstract Copy Title: Astragalus peckii Population Establishment: Developing Protocols for Seed Germination, Seedling Cultivation, and Planting Author: Pearson, Tabitha Astragalus peckii Piper is a threatened Oregon endemic in the pea family (Fabaceae). This species faces extinction due to loss of habitat. Recovery efforts include augmenting existing populations and creating new ones. The purpose of this study was to determine the best methodology for population augmentation of Astragalus peckii by evaluating methodologies for 1) seed germination and seedling cultivation, and 2) transplant survival and seed emergence. Older seeds required manual scarification to induce germination while younger seeds germinated without treatment. Seedlings were placed in three soil treatments with varying ratios of potting mix and native soil. Seedlings experienced high rates of mortality unrelated to treatment. Seeds and seedlings were planted in the fall along four transects of varying disturbance and previous species occupation. Spring survival rates provided little evidence for an increase in population size of Astragalus peckii in the four transects after planting.

  Citation × Citation Citation Abstract Copy Title: HOW DO CONSERVATION LAND TRUSTS COME TO EMBRACE AGRICULTURE? A CASE STUDY FROM OREGON Author: Pruch, Jared Year: 2017 In part because of the state’s unique land use system, Oregon’s land trusts have largely focused their efforts on the protection of lands with wildlife habitat values, rather than productive agricultural land. And yet a confluence of contemporary trends – including population growth, aging farmer-landowners, and a growing regard for the conservation values embedded in well-stewarded farmland – are causing some land trusts to re-evaluate their conservation priorities. By conducting in-depth interviews with land trust staff and board members, farmers and ranchers, and land use advocates around the state, my work seeks to make transparent the network of influences underlying this shift. Making use of nonprofit management theory, I argue that land trusts change their conservation priorities through a combination of environmental assessment and managerial vision. Several predictors – willingness to innovate, agricultural representation within the organization, and community priorities – increase the likelihood that land trusts will include farmland as a conservation priority.
