Invasive and Problem Plants

Invasive and Problem Plants

Since the soil in the areas in and along the trail has been disturbed (graded and used as a road) over the years, many destructive plants have been brought in. These are a few of the worst ones. Many non-natives included in the Upland Plants of Batiquitos page are also invasive or problematic plants.
