Rare Plant Mitigation

Joli Ann Leichtag Elementary School Wetlands and Rare Plant Mitigation, San Marcos Unified School District

Thread-Leaved Brodiaea Transplantation Project Thread-Leaved Brodiaea Transplantation Project Thread-Leaved Brodiaea Transplantation Project

We assisted the San Marcos Unified School District (District) with implementing all project-associated biological mitigation for the construction of a new elementary school in San Diego County. We helped establish nearly two acres of wetlands and riparian habitat along Agua Hedionda Creek, and transplanting an estimated 30,000 endangered thread-leaved brodiaea (Brodiaea filifolia) plants into a seven acre grassland preserve.

We refined specialized transplantation techniques using heavy equipment to successfully transplant the endangered bulb species. We worked with Dudek over the seven year maintenance and monitoring period to ensure successful completion of both the wetland and rare plant mitigation components of the project.

Both mitigation projects have exceeded success criteria. HRS and Dudek continue to manage the preserve area for the District. The project earned HRS and Dudek an award from the Association of Environmental Professionals for a meritorious environmental solution.
