On 10 June 2010, I used a Trimble Geo Explorer to map patches of Otay tarplant on the Mother Miguel grassland. I walked throughout the site, and when I encountered a patch of tarplant I recorded a polygon depicting its perimeter. I considered tarplants more than 2 m apart to be in separate patches, and patches to consist of at least one individual tarplant every 1 m2.
