The goal of this program is to monitor Saguaro National Park's trails network primarily through volunteer assistance, thus eradicating a suite of exotic plants from human transportation vectors. The collective group of weed-free trail monitors will monitor trail segments a minimum of once per year, as scheduling and time permit.

We ask that volunteers attend an orientation on:

  • Expectations of NPS on volunteers
  • Plant Identification
  • Project parameters
  • GPS training
  • Outreach training
  • Cultural training
  • Radio training
  • Safety Training
 

Orientations are held periodically. Feel free to email SAGU_Invasive@nps.gov or call (520)733-5187 with any questions regarding Saguaro National Park's Weed Free Trails Program.
