At the EarthLab Native Plant Propagation Center, students learn that there is no aspect of biological life that is not dependent upon plants for survival. Plants provide and clean the oxygen we breathe, improve water quality, prevent erosion, buffer the climate, and provide habitat for wildlife. They provide emotional and aesthetic benefits. Students learn that each plant species is adapted for that environment, and is critical to its specific ecosystem.

Urbanization and creek channelization in the Chollas Creek Watershed have eliminated valuable plant species, and allowed nonnatives to survive and thrive. This loss of native species threatens air and water quality, biodiversity, and open space enjoyment. Students work with homeowners and public agencies to utilize the thousands of plants they grow to improve their ecosystems in backyards, parks, and public spaces.
