A Systems Approach to Seedling Establishment on Degraded Rangeland:managing Ecological Processes Driving Recruitment Bottlenecks (Unr Leger)
Range and Meadow Forage Management Research
2013 Annual Report
1a.Objectives (from AD-416):
Identify seedling traits from different seed sources that increase probability of seedling establishment.
1b.Approach (from AD-416):
The approach is to collect seed sources from multiple populations, including commercial cultivars and sow seeds and a subset of sites selected in the Great Basin. Populations will be screened for numerous root and shoot physiological and morphological traits.
This project relates to Objective 2 of the parent project, "Working with cheatgrass and medusahead, develop new ecological principles that contribute to the basis of EBIPM by investigating the potential interactions among management approach selection, site availability, species availability, and species performance during restoration of cheatgrass and medusahead-dominated rangeland". In FY 2013, plots were established at the selected sites in Nevada. Grasses have been grown for transplanting at the selected sites in Fall 2013. Data collection has been initiated and all research is on track according to timeline.
