Spend the morning at Bommer Canyon as we take part in stewardship activities at our Monarch Butterfly Plot. Stewardship activities include weeding invasive species, mulching and watering native species as part of our enhancement project. With your help we will create islands of milkweed and nectar plants that will help support the seasonal migration of monarch butterflies. All necessary tools and personal protection equipment to complete this work will be provided. We may use shovels and small handheld tools. No experience necessary!
