Join KS Wild, Bureau of Land Management, Friends of the Cascade-Siskiyou National Monument and the Native Plant Society of Oregon for an invasive weed pull in the Mariposa Preserve.

Just outside of Ashland, this 222-acre Botanical Area is a designated conservation area (botanical preserve) that lies within the Cascade Siskiyou National Monument. It was first acquired in 1993 through a unique land exchange between The Nature Conservancy and cooperative ranchers in the Rogue Valley. It contains portions of the historic Oregon-California Trail, and provides year-round habitat for blacktail deer and a small elk herd.

The preserve serves to protect two rare endemic plants: Greene's Mariposa Lily (Calochortus greenei) (the Botanical Area's namesake) and Detling's microseris (Microseris laciniata ssp. detlingii). Greene's Mariposa Lily only grows in southern Jackson County, Oregon, and northern Siskiyou County, California, while Detling's microseris exists only in select areas of Jackson County, Oregon. We will continue to clear yellow star thistle and observe wildflowers blooming along the way.
