Abstract: Introduced animals have weakened the precipitation-absorbing and soil-stabilising indigenous protection forests, causing accelerated erosion and increased flooding. There is a demand from foresters and rangers engaged on animal-control work for simple techniques to enable them to assess objectively the protective efficiency of animal-infested forest in a primary reconnaissance and then, by the response of the vegetation, the effectiveness of their animal-control operations. This paper offers two simple techniques to fill this need. They are tools to be used only until the Forest and Range Experiment Station has surveyed all important protection catchments and established systems of permanent transects and plots to record vegetation changes comprehensively.
