Summary

The dataset contains a time series of cheatgrass dieoff maps covering the western and central areas of the northern Great Basin. This dataset maps annual cheatgrass performance in the northern Great Basin, USA, from 2000-2010, using the dynamic monitoring of ecosystem performance (DMEP) method. The power of DMEP is that it separates weather-related performance issues from disturbance- and management-related performance issues by integrating satellite data with land cover data, seasonal weather data, and a site potential dataset into a regression-tree model. The resulting model is called the expected cheatgrass performance (ECP) model, and this model performed well (R-square equaled 0.88). The EEP model results are statistically compared [...]

Purpose

To reliably identify the extent of the cheatgrass dieoff phenomenon in the northern Great Basin and to facilitate an effective monitoring project that provided science-based information on dieoff magnitude and trends and provided robust data to inform predictive models and analytical tools for current and future management.
