Methods

Forest inventory surveys were initiated in 1965 repeated in 1977 and repeated at 5 year intervals after that; this data set was collected in summer of 2002. The inventory consists of a total inventory of all trees >=10 cm diameter-at-breast-height (dbh) on the whole of the watershed (13.23 ha) as measured in each of the 208 25 m x 25 m plots. Trees >=2 to <=10 cm dbh were subsampled using a 3 meter wide strip along one edge of each 25 m x 25 m plot. With the addition of tree tags in 2002 on all trees >=10 cm dbh tracking of individual trees is now possible. The inventory consists of a total inventory of all trees >=10 cm dbh (except for 1965 where it was for > = 1.5 cm dbh) on the whole of the watershed (13.23 ha) as measured in each of the 208 25 m x 25 m plots.
