This study employs functional diversity metrics and guilds—suites of species with similar traits—to assess the influence of an invasive tree (Tamarix spp.) on riparian plant communities in the southwestern United States. Nine distinct guilds were identified with a gradient of functional diversity related to both tamarisk cover and environmental conditions. The identified guilds can be correlated to specific site conditions and can be used to anticipate plant community response to restoration efforts and in selecting appropriate species for revegetation.

A look at beetle-occupied tamarisk sites 11-13 years after initial occupancy to determine long-term vegetative community response. Study found that Tamarix cover across sites initially declined an average of ca. 50% in response to the beetle, but then recovered. Changes in the associated plant community were small but supported common management goals, including a 47% average increase in cover of a native shrub (Salix exigua), and no secondary invasions by other non-native plants.

A common garden study of six distinct Fremont cottonwood populations across an elevation gradient and covering a range of genetic variation to determine responses to different heat conditions. The common gardens had mean annual temperatures of 11, 17, and 23°C and all received regular watering throughout the growing season.

This document is designed to serve as a Scope of Work for contractors or staff completing revegetation (planting and/or seeding) projects, as well as a documentation of work completed on a single page. It is a fillable pdf but can also be downloaded blank to fill out in the field, or adapted to individual project needs.
