The Challenge

As part of our 50th Anniversary festivities, the Marin CNPS Board presents you with the following Challenge: find and photo-document 50 native plants in Marin’s glorious wildlands and be eligible for a drawing at our August 24th Celebration! Prizes may include plant-oriented books, restaurant gift certificates, and more!

The goals of the Challenge are to highlight the beauty and diversity of Marin’s native flora and to focus attention on the habitats where these especially interesting plants thrive.  We hope many will enjoy observing these plants in places both familiar and new.

How to Take Part in the Challenge

The Challenge will run from March 1 through July 31, 2024, and only plants documented within this period and within Marin County will qualify.  Choose your 50 native plants from this List of 75 species compiled by our Committee. The List includes habitat information and suggested trails to help you find the plant.

Participants will document their finds in an iNaturalist Project entitled Marin CNPS 50th Anniversary Native Plant Challenge. When you find a plant that is on the List, click on the camera icon on the iNaturalist app to take a photo. Follow the prompts to upload it into the Project.

Committee members are not eligible for the drawing, but will be taking part for fun, monitoring participants’ efforts, and cheering them on!

Need Help? Never fear! Our new field trips team is planning hikes geared to the target plants and an iNaturalist orientation to help you get started.

You can also use this illustrated guide to familiarize yourself with the Challenge plants before you hit the trail.
