Estimated numbers of individual native plants per 100 m2, and percentage change in the numbers of plants after fire and/or spray in the 1–2 years preceding a survey.

We also present the estimated percentage change in the abundance of individual plant species response in to an increase in Bitou Bush cover of a tenth of the area, and the percentage change per year in the absence of spray, fire or change in the cover of Bitou Bush. Only effects significant at the 5% level are shown. Information on life forms are based on data in PlantNET [31]. We present data for the 19 individual species for which 400 or more individuals were recorded.aBased on data from 1 m x 1 m survey plots (see text).Estimated numbers of individual native plants per 100 m2, and percentage change in the numbers of plants after fire and/or spray in the 1–2 years preceding a survey.
