Nature walk at the DWP Trail Corridor 9.13.22

On a beautiful Fall evening, the Arrowhead Native Plant Explorers met with Jeffrey Flory of the 1854 Treaty Authority to learn about invasive non-native species in the Arrowhead region and their effects on native species. Jeffrey discussed the threats that invasive plant species can pose to native species by displacing their habitat. We met at the Mission Creek parking area and then walked along the DWP trail corridor and discussed plant species along the route. At the end of the evening, Jeffrey distributed informational brochures and boot brushes and discussed how we could get involved to stop the spread of invasive plants in the Arrowhead region.
