Abstract
New Zealand's planted forests sector is the country's third largest export earner. Rising interest in green consumerism is leading to increased demand for scientifically defensible information on the sustainability credentials of forest products. International reporting mechanisms such as the Global Forest Resources Assessment, the Montréal Process and forest certification schemes require reporting on the state and trends in planted forests. Data availability for such reporting is variable. This paper explores the types of issues that arise when evaluating the applicability and usefulness of existing national environmental data sources for reporting, including the compatibility of attribute information, spatial data resolution and coverage, and extending existing data through analysis.
We conclude that the data sources could mostly be used, with some provisos and some additional information collection. The recommendations will contribute to a new web-based planted forest information portal under development for New Zealand's planted forests.
