CalTransCalTrans I-5 Native Tree Planting

Project Summary
Type Habitat restoration project
Project Lead Chris Robbins
Partner Caltrans

Project Overview

The Project is a cooperative agreement between CalTrans and the Yolo RCD. This project consists of planting native trees, shrubs, and grasses at six interchanges along Interstate 5 in Yolo County. The project includes the installation of drip irrigation system at each interchange. Trees, shrubs, and grasses will be planted, protected with tree protectors, mulch will be placed around plants, fertilized, and watered in. Plants will be irrigated as appropriate. Areas will be maintained for weed control using mechanical and chemical methods. Any dead plants will be replaced. The plantings will be maintained for a 3 year period.

Additional Information

Biological and Economic Effects

Tree plantings will reduce the area in need of maintenance, reduce fire risk, and reduce invasive weed populations. The native grass plantings can improve soil properties and reduce erosion along roadsides. The native plantings will provide potential habitat for native pollinators and potential habitat for small mammal and bird species.

Public Use Sites are located in Interstate and road interchanges no physical public use is expected, but has an aesthetic value.

Funding
