Distribution of an occurrence of Otay tarplant (Deinandra conjugens) was mapped with a Trimble GeoExplorer on 10 June, 2008, on the Mother Miguel grassland area of San Diego National Wildlife Refuge. I looked for tarplant throughout a considerably larger area than the positive results reflected in this layer would suggest (i.e., on both sides of the utilty road that runs past the old San Miguel Ranch House site).
