Spatial Patterns and Management Implications of Native Bunchgrass Recovery Following Oak-Pine Savanna Restoration in the Mid-Elevation Oregon Cascades
(University of Oregon, 2022-10-04) Horton, Eyrie; Johnson, Bart
Restoring native grasslands by counteracting the forest succession which followed the loss of historical fire regimes is a vital component of landscape management in the Mediterranean moist climate of the western Pacific Northwest, USA. However, canopy cover reduction alone does not assure healthy grassland regeneration. Site-specific and species-level research is needed to identify effective restoration strategies. I examined two native bunchgrasses, Festuca roemeri and Festuca californica, in the Jim’s Creek Restoration Area (Jim’s Creek) to assess their relative success across varying microenvironmental and competitive gradients prior to and following restoration. To make these findings more accessible, I developed a handbook that employs a graphic language to make scientific research findings accessible to land managers and those who may not have a background reading statistics-based, ecological literature. This thesis includes unpublished co-authored material.
