The 7-digit numbers are the USGS equivalent. Red marks signify uncertainty[?] or extirpation[*]. See quad list above. A complete key is on the Index by Topo Quad page. Marks are smaller than the quads they represent, and are generally positioned near the center of the quad. In some coastal quads, this will place the mark offshore. Quad boundaries do not coincide with county lines. To confirm county location, refer to the county list below. Counties, states, regions: Del Norte (DNT), Humboldt (HUM), Mendocino (MEN), Trinity (TRI), Oregon (OR) counties map Quad Mark Identifier CNDDB Quick Viewer Web application for exploring the CNDDB elements reported at the quad level.
