Fiordland ecology: The altitudinal gradient in forest composition, structure and regeneration in the Hollyford Valley, Fiordland

[First paragraphs...]
The forest on the eastern side of the Hollyford Valley in the vicinity of the Deadman's Hut-Harris Saddle track was analysed to describe the changes in composition, structure and regeneration of the forest associated with a change in altitude from the valley floor at 300 ft. a.s.l. to the treeline at 3250 ft. Such an approach resembles the" gradient analysis" of Whittaker (1956), although the method used was somewhat different.
Results of a similar study made recently on undisturbed forest at Blanket Bay, Secretary Island, about 70 miles to the southwest (Mark 1963), provide a useful comparison.
