![]() ![]() Some species of native grass seed are commercially available, but it is expensive, and would not reflect the local genetic variations. Since 2000, the National Park Service has been attempting to increase native seed use in these pastoral zones. The National Park Service now prohibits the planting of these invasive species in the approximately 7300 hectares (~18,000 acres) of grazing allotments within Point Reyes National Seashore and the north district of Golden Gate National Recreation Are. Unfortunately, invasive non-native grasses, such as Velvet grass ( Holcus lanatus), Harding grass ( Phalaris aquatica), and Tall fescue ( Festuca arundinacea), were planted as well. While these are non-native species, they fortunately are not invasive. The most common forage plants seeded on these lands are Italian ryegrass ( Lolium multiflorum) and clover ( Trifolium sp.). Since then, ranchers planted many non-native grasses, many of which were invasive and began to out-compete the native grasses. Coastal prairie is dominated by long lived perennial bunchgrasses, such as Purple needlegrass ( Stipa pulchra), California fescue ( Festuca californica) and California oatgrass ( Danthonia californica), all of which can stay green year round with the moisture provided in the fog belt.īy 1850, dairy ranchers had arrived at Point Reyes, lured by the near-ideal conditions for raising cattle. Deschampsia coastal prairie is found on the Point Reyes peninsula and Danthonia coastal prairie is found on Bolinas Ridge. ![]() Pristine patches of this vegetation still grow at Point Reyes on either side of the San Andreas Fault. ![]() The northern coastal prairie, which extends into Oregon, is the most diverse type of grassland in North America. Less than one percent of California's native grassland is still intact today. ![]()
