Assessing the Impacts of Brush Management on Herbaceous Diversity and Primary Production in Southern Arizona Grasslands

Approach

This project implemented a comprehensive invasive and nuisance plant species removal restoration approach, combining scientific research with community engagement and traditional ecological knowledge.

Implementation Steps

1. Baseline assessment and site selection
2. Stakeholder consultation and community engagement
3. Design and planning phase with technical experts
4. Implementation with local workforce training
5. Monitoring and adaptive management

Timeline

The project was implemented over a 2-year period, with ongoing monitoring and maintenance continuing beyond the initial implementation phase.
