Morro Bay State Park

2. Across from the Campground entrance. This patch starts at the cable junction box opposite the first entrance to the ranger residences, and extends for 75 feet along the south side of State Park Road.

3. 300 feet east of the Campground amphitheater.

4. In the group campground growing under the pines at the east edge of the Osos site.

5. At scattered sites along the exercise trail, sometimes protruding into the trail.

6. In the woods south and east of the fourth golf hole (none where the grass has been mown)  to the summit of Black Hill, often at the edges of trails.

7. In the pine forest above Ridgeway Street on and under some of the trees. None at the edge of paths.

8. From Quintana at La Loma 2/3 of the way to South Bay Boulevard.
