Description: The Nelder Wheel is a single tree systematic experimental design. Its major application is for plantation spacing experiments. The design allows for the testing of a number of spacings in a small area. Data obtained is useful in determining the response of stem diameter and crown diameter to spacing. Data is not compatible with data from conventional plots unless single tree modeling is utilized. The design is sensitive to individual tree losses. Nelder Wheels were planted at Cal Poly, San Luis Obispo with eight species of eucalyptus and a hybrid poplar in 1980. First year growth results are presented.
