Scion is the leading provider of forest-related knowledge in New Zealand
Formerly known as the Forest Research Institute, Scion has been a leader in research relating to forest health for over 50 years. The Rotorua-based Crown Research Institute continues to provide science that will protect all forests from damage caused by insect pests, pathogens and weeds. The information presented below arises from these research activities.
From Forest Health News 87, July 1999.
With the proliferation of small cypress woodlots around the country, and expressions of concern about cypress canker disease, there is a need to determine the impact of this disease on the changing resource. A countrywide survey is therefore being conducted by the Forest Health and Biosecurity Project, with the assistance of Special Purpose Species, Forest Research. Information is sought on the incidence of the disease in different regions, host species, stand types and under different silviculture treatments. As part of the survey, a questionnaire has been devised and distributed with the assistance of the New Zealand Farm Forestry Association, and by means of an insert in Tree Grower magazine. The survey has the backing of the newly formed Cypress Development Group, and information obtained will be made available to this body, and to all who respond. Accompanying the questionnaire form is a leaflet describing and illustrating the disease, for those who are not familiar with the symptoms. The form has been structured using a "user-friendly" format, and return postage is freepost, to encourage response. Replies from growers without disease are also solicited. Any who would like to assist, and who do not yet have a questionnaire, please apply to Forest Research.
