A timberline stand of Libocedrus bidwillii subalpine low forest at Pegleg Flat, Arthur's Pass, was partly destroyed by fire in the late 19th century. Patches of surviving low forest contain very few Libocedrus seedlings and lack young trees of 5-15 cm d.b.h. Only 14 large seedlings and saplings were located in the post- fire sere in the formerly burnt areas. The small numbers of seedlings on both undisturbed and disturbed sites have not replaced the trees which were burnt or died of natural causes and Libocedrus is now absent from certain, climatically unfavourable locations.
