Samples of stomach contents were collected from 104 feral pigs (Sus scrofa) shot in the Urewera Ranges between December 1982 and June 1985. These were sorted into food items which were dried, weighed, and combined to give estimates of their annual and seasonal diets.
Seventeen exclosures were built by the New Zealand Forest Service within Urewera forests over the period 1961-68 to exclude ungulates. Forest structure and species composition inside and outside these exclosures were compared in 1980-81. Some relatively shade tolerant species such as the fern Asplenium bulbiferum, the liane Ripogonum scandens, the sub-canopy shrubs Geniostoma ligus,Trifolium and Coprosma australis and the canopy species Beilschmiedia tawa were less abundant in certain tiers outside the exclosures than inside.
