Fire Ecology - Vegetation Types: Coastal Dune
Native dune habitat in California is rare and is threatened both by development and by non-native species. The majority of dune habitat at Point Reyes is dominated by non-native species including European beachgrass. Approximately 2,000 acres of the Seashore is coastal dune habitat (see Vegetation Map).
Native dune habitat is comprised primarily of dune sagebrush (Artemisia pycnocephala), coast buckwheat (Eriogonum latifolium), dune lupine (Lupinus chamissonis), or goldenbush (Ericameria ericoides). Non-native dunes are dominated by European beachgrass (Ammophila arenaria) and iceplant (Carpobrotus edulis).
Total vegetation cover in coastal dune ecosystems is often low and interspersed with bare sand. Although there may be thatch buildups in European beachgrass, these communities are generally not very flammable.

Climate scientists warn that the safe upper limit for atmospheric carbon dioxide (CO2) concentrations is 350 parts per million (ppm). For most of human history, atmospheric CO2 rarely exceeded 275 ppm--until the industrial revolution. As of 2013, atmospheric CO2 was ~400 ppm–-and rising 2 ppm/year. More...
