The fungus Botryosphaeria dothidea will grow between one to five millimeters after a week on the chaparral species Rhus integrifolia. To test this, we inoculated six individual shrub located behind the greenhouse on Campus Walk Road . On each shrub we selected two branches, receiving adequate and equal sunlight and inoculated one branch with the fungus B. dothidea and the other with a plain gel in order to compare the growth with a control group. The data we collected at the end of the one week period was similar to our initial hypothesis. The shortest growth was on the fifth individual Rhus integrofolia shrub at 2.5 mm. The longest growth was on the second shrub at 6.23 mm. We concluded that the fungus could thrive and spread rapidly in other chaparral species.
