Current Sponsored Projects
- Data/meta-data Archive for the DEMO Study
Funds from this agreement will support implementation of standard QA/QC protocols on recently collected (2016) data; merger of these with historic data; updates to meta-data; archiving of data and historical documents at OSU-FSDB; and transfer of raw/summary data to USFS-PNW.
- Long-term Responses of Vegetation to Variable-retention Harvests
An extensive array of permanent sample plots facilitate periodic assessments of the structural and biodiversity values of these experimental treatments. The supplemental funding provided by this cost-reimbursable agreement will support a 17- to 18-year remeasurement of these plots with a focus on patterns of tree regeneration and their relationships to overstory structure.
