Research Project: Rosaschi Ranch restoration research project

Location: Great Basin Rangelands Research

Project Number: 5370-22000-023-05
Project Type: Nonfunded Cooperative Agreement

Start Date: Apr 24, 2009
End Date: Sep 30, 2013

Objective:
Techniques for the revegetation of former agricultural lands will become more important as water rights are transferred from agriculture to other uses in the arid western U.S. The US Forest Service has acquired property with abandoned fields at Rosaschi Ranch on the East Walker River in the southern Great Basin. We will conduct factorial experiments testing the roles of (1) first-year irrigation, (2) seed mix functional diversity, and (3) alternative site preparation techniques in the establishment of native species on these abandoned agricultural fields. The experiments will take place over two years, and data collection will occur during years two through four of the project. Subsequently, a full-scale restoration plan for Rosaschi Ranch will be completed, incorporating applied research to maximize restoration success.

Approach:
This project will use experimental restoration projects deployed in two initial years and monitored in years two through four to guide restoration planning and implementation on all bare agricultural fields at Rosaschi Ranch. These experimental projects will result in demonstration plots that could be used to: 1) illustrate the effectiveness of different seeding techniques and seed mixes; 2) ask research questions that will inform future efforts to restore agriculture lands; and 3) build support for the project by demonstrating success. Rigorous analysis of results from these experimental projects will allow for the design of a restoration plan for Rosaschi Ranch that will be successful over the long term. Research plots will examine major factors in a large-scale experimental design, and additional factors in a small-scale experimental design.
