Landscape Narrative	Upland; Description of the plot in relation to the rest of the stand: Perhaps polygon a little small but very little edge effect. Some Brassica nigra on one side because of edge effect. Salvia leucophylla cover in this plot is because of edge effect with Salvia leucophylla inclusion. Good modal representation, avoided area in polygon where Hazardia squarrosa was denser.
