Endangered Burke’s goldfields

This picture shows fruits of federally Endangered Burke’s goldfields (Lasthenia burkei), an annual species of the Sunflower family. It is identified by its one long pappus bristle and several short bristles. During surveys in 2010, Nomad Ecology botanists recorded a single population of this species within Lake Mendocino, which is owned and operated by the U.S. Army Corps of Engineers. Burke’s goldfields had not been seen in Mendocino County since 1886, when this species was first discovered by J.H. Burke.

This form does not yet contain any fields.

    Nomad Principal and Senior Botanist Heath Bartosh will be lecturing about the sandmounds of Oakley, California. These scattered deposits of wind-blown sands from the confluence of the Sacramento and San Joaquin rivers harbor an assemblage of unusual plants which constitute a vegetation community unique to this region, and which has largely gone unnoticed by the scientific community. While much of the dune area and attendant plants have been destroyed by development, significant pockets of intact habitat remain.
