Oregon Gulch RNA

Oregon Gulch Research Natural Area (RNA) was established to represent slopes and riparian reaches of Oregon Gulch in the Jenny Creek watershed. About 60% of the oak/grassland habitat contains rock outcroppings. Vegetation of the RNA includes: western juniper/Oregon white oak (Juniperus occidentalis/Quercus garryana) scrubland, Oregon white oak/wedgeleaf ceanothus (Ceanothus cuneatus) bunchgrass, Oregon white oak/ponderosa pine (Pinus ponderosa) forest, mixed conifer/California black oak (Quercus kelloggii) forest, and various riparian communities. Woolly meadowfoam (Limnanthes floccosa ssp. Bellingeriana) and Greene's mariposa lily (Calochortus greenei) are Bureau sensitive plants within the RNA and Howell's yampah (Perideridia howellii) is a Bureau watch species. A pond near the top of Rosebud Mountain is surrounded by several non-native species.
