Much of the research is about improved baits and poisons, though bio-control is one of the newer and more innovative mechanisms being researched. Biocontrol research programmes tend to follow one of two directions. The first involves targeting physiological pathways such as the reproductive system while the second is looking for potential vectors such as viruses and parasites. Good progress is being made in fundamental biocontrol research, but it expected that possum control will require a mix of methods for some years to come. Possums cause extensive damage to indigenous forests and are the major vector of bovine Tb to cattle and deer.
Possums also prey on nesting birds.
As well as being expensive, these methods of control are becoming less socially and politically acceptable. The first outcome of the Joint Statement was a visit to New Zealand of a Korean survey in early July 2000. The mission explored bi-lateral opportunities to cooperate in the biotechnology, IT, telecommunications, engineering and environmental technology sectors. Information from the visit, including New Zealand company profiles, will be entered into a Korean Government database and accessed by the Korean business sector. The mission will be followed up by a 'Technomart' in Korea later in the year.
