Plant diversity assessment on Mount Cameroon: surveys from 1990 to 2000

Between 1990 and 2000 a number of vegetation surveys were undertaken on the Mount Cameroon area using mainly three methods: 0.25 ha sample plots, 20 m wide transects and rapid botanical surveys. A comparison of these methods in terms of data collected, operational characteristics and output relevance, revealed their strengths and weaknesses. The methods vary markedly in their ecological value (0.25 ha sample plots superior), taxonomic scope and rigour (rapid botanical survey superior) and logistic efficiency (transects superior). The combined outcome of all these surveys is discussed and recommendations made on the use of the rapid botanical survey in order to rapidly fill the remaining gaps on plant distribution.
