Conteúdo: | Abstract: The wheel point and point frame methods were compared in the measurement of plant cover for a range of vegetation types and species in the Western Division of New South Wales. Although there was generally no statistical difference between techniques, observations suggest that the point frame tends to give lower estimates of cover than the wheel point in the situations measured. This may be associated with the circumference of the marker pins on the wheel point or perhaps observer error but as this effect appeared to be more noticeable with grasses the former is most likely. The wheel point is less time consuming, more convenient and simpler to use than the point frame, and will readily accommodate most temporal and spatial variation in sampling requirements in similar land forms in western New South Wales.
