There's a new bad guy in town, Volutaria tubuliflora, Mediterranean desert knapweed, which may be yet another potentially-highly-invasive species similar to Brassica tournefortii, Saharan mustard. The bicycle is leaning against three mature plants of it in Borrego Springs. See also the Invasion of the Volutaria pulp magazine cover created by James Dillane.*
You have an opportunity to help stop this aggressive plant in its tracks. A group weed-pull is organized for Friday, March 6, 2015 from 9:30 AM - 12:30 PM. Meet 1 mile north of Palm Canyon Drive on Borrego Valley Road. Americorps NCCC Team Silver 6 will be there to help.
Bring water, sunscreen, and lunch/snacks. There will be celebration and reflection at Christmas Circle.
The event is co-sponsored by the Anza-Borrego Desert State Park® Botany Society.
