Observation Narrative
Plot located on the most intact portion of a heavily trampled cliff top. The habitat is scoured by catastrophic floods with an average return interval from 12 to 30 years. Because of extensive disturbances, and the narrow area between the cliff edge and a trail, it was only feasible to sample a 200 sq. m. plot.
