The regeneration of commercial eucalypt forests on Surrey Hills, N.W Tasmania

The quantity and quality of eucalypt regeneration in all the important forest types on Surrey Hills and adjacent areas has been evaluated in the period between October 1969 and August 1971. The rate of stocking was determined by estimating numbers and distribution of seedlings. Growth was estimated by determining height increment with age. Both stocking and growth were related to a)the site quality evaluated from past forest growth, and b) by the logging and regeneration practice used on the area. The survey was conducted by sampling on a grid pattern using milacre plots at a spacing of 4 x 1 chains as described by Mount (1961). A total of 1,800 plots were sampled
