Since opossums were introduced to NZ from Australia, possibly as early as the 1830s by pioneer settlers, these animals have become one of the most difficult of the introduced pest species to exterminate. The opossum was brought into NZ to create a fur industry and by the l890s had established colonies in several areas, from which spreading took place. Even then complaints about the destructive ability of the 'possum were being received, mainly from gardeners and orchadists. Later these incresed with fruitgrowers,and farmers joining, along with acclimstisation societies and those who early-on recognised the threat posed to the native ecology, fauna and flora. This anti-possum cause was strengthened when catchment and roads boads and related official organisations lodged similar complaints. An 1920 official strudy of the situatiion found that the existing trade in skins favourably countered any adverse effects to other sectors, with little in the way of controls and enforcement eventuating. A trapping season was introduced and liberatiion restricted, but little employed. For many years the Department of Internal Affairs had overseen opossum control for the Government. In 1922 all the existing regulations were cancelled and authorisations to liberate withdrawn. These rules, in the main, remained in force to 1946, although the 'possum issue remained controversial with "a great numbers of unauthoriseds releases" up to 1940. Toward the end of the 1940s Internal Affairs conducted a national survey of the distribution, damage and effect on forests the amimals were causing. This found that positive action was required in some areas and interim control measures were introduced in 1951 which included payment of a bounty on all apossums killed, where the skin was not taken. In 1956 all opossum control was transferred from Internal Affairs to the NZ Forest Service. The Service, in 1963, first published "The Opossum in New Zealand" booklet, based on earlier official publications. In 1969 this reprint edition of the booklet was released with the stated objective of ".encouraging local control" while ". explaining for potential trappers, efficient methods of taking oppossums and caring for skins." Today the campaign to control opossums continues, apparantly without any "just around the cornrer": resolution. Printed by the NZ Government Printer the 52 page booklet has card covers with opossum photo to front cover. Text is divided into several sections covering Description and Habits, which includes breeding, movement and spread, forest damage. encological impacts; Taking Oppossums, has trapping, lures, trap setting, equi[pment reqired, general methods of control; poisioning, hunting, possum-proof fences; Skinning , general procedures, pegging out for drying, bundling/pressing, dispatch. Other isues discussed are alternative methoths of skinning and drying, grading skins/assessing seasonal skin condition, plus a note on home-curing skins. The final seven pages list browsing preferencs for the animal, covering trees, small trees, shrubs, creepers etc in descending order of preference, giving the technical and common usage names.--- a final section lists some of the fruits 'possums preferred. The booklet is illustrated throughout with b/w photos of a general nature plus plans/diagrams for trapper's camp, snares. box trap, skin pegging diagram etc, with actual skinning propcedures covered in progressive b/w photos.
