Data From: Release And Establishment Of The Weevil Mecinus Janthiniformis For Biological Control Of Dalmatian Toadflax In Southern California

We monitored populations of the stem weevil, Mecinus janthiniformis , the invasive alien weed Dalmatian toadflax (Linaria dalmatica) and other vegetation to document the impact of using M. janthiniformis as a biological control agent of L. dalmatica. Weevils were released in 2008 and again in 2014 after a wild fire. The results document increases and spread of weevil populations, decrease in Dalmatian toadflax and changes in cover of some vegetation classes.
