Field Guide for Selecting the Most Appropriate Treatment in Sagebrush and Pi?on-Juniper Ecosystemsnin the Great Basin. Evaluating Resilience to Disturbance and Resistance to Invasive Annual Grasses, and Predicting Vegetation Response.

摘要

This field guide identifies seven primary components that largely determine resilience to disturbance, resistance to invasive annual grasses, and plant succession following treatment of areas of concern. The primary components are (1) characteristics of the ecological site, (2) current vegetation prior to treatment, (3) disturbance history, (4) type, timing, and severity of the treatment, (5) post-treatment weather, (6) post-treatment management, especially grazing, and (7) monitoring and adaptive management. A series of key questions and a set of tools are provided to assess these primary components. This assessment is designed to allow field personnel to (1) evaluate resilience to disturbance and resistance to invasive annual grass for an area of concern, (2) predict the potential successional pathways, and (3) then select the most appropriate treatment, including the need for seeding. An evaluation score sheet is included for rating resilience to disturbance and resistance to invasive annual grasses and the probability of seeding success.
