Invasive Plant Project

Help us bring native plants back to the Preserve!

The Invasive Plant Project (IPP)

Stinknet, sometimes called Globe Chamomile, is a highly invasive weed, originally from South Africa, that grows fast, spreads fast, and, when it dies, becomes dangerous kindling for wildfires. It is so invasive, as well, that it has been outcompeting native plants on our trail!

Last year, we began the long task of trying to remove invasive plant species (i.e., stinknet/globe chamomile) from the trail. We had incredible volunteers who came out to help us weed, and we have also started creating seed balls to spread wildflowers across the trail and have even begun planting native trees and cacti along the trail! 

IPP is back, and we need your help again! IPP is a monthly event, and we will have different tasks each month! Look below to see upcoming IPP days. Some days will have specific themes or tasks, so click the date to learn more!
