Rats and later White-tailed deer were early invaders of both Ulva and Stewart Island and over the years had a significant effect on forest ecosystems.
The deer problem was addressed by NZ Forest Service as early as 1969/70 with a hand poisoning program, which was ultimately successful after some 4 or 5 years work. This resulted in significant regeneration of palatable species.
Department of Conservation took over management of Stewart Island from the old Lands & Survey Dept and NZ Forest Service in the '80's and initiated a hand eradication program aimed at rats in the '90's. This probably took only 9 months work although it was another 4 years before the Island was declared rat free and threatened/endangered species liberation could begin.
Today Ulva Island has joined an elite group of animal free sanctuaries and is perhaps the closest to pristine of any area of new Zealand open to the public. The response of Ulva Island to it's animal free state is best illustrated by a comparative walk through forest on Stewart Island, followed by time on Ulva.

to supplement my own observations. . Long out of print and coffee table size it is often found in second hand book shops at around $50.

In time I hope to build a library of the various songs and phrases we hear. You will find these on the appropriate birds pages, with a short explanatory note as to the circumstances. The recordings will be in MP3 format. But the original recordings are .wav, sampled at 24bit/96khz.
