New field guide: “A Guide To Understanding Nectria Flute Canker Related Defect in Mature Trees”
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 202, February 2010.
The Forest Health Research Collaborative and the WQI Ltd. have funded Scion to produce a pocket field guide on Nectria flute canker in mature trees. It is based on the results of several studies in mature trees conducted by Scion and Wood Quality Focus with support from the WQI Ltd. and the Nectria Focus Group.
The objective of the field guide is to assist in the identification and assessment of defect caused by Nectria flute canker in mature trees, with particular reference to pre-harvest inventory of pruned stems. The guide illustrates a range of defect types found in mature trees thought to be associated with symptoms Nectria flute canker disease that developed when the tree was younger. A method for assessing the severity of Nectria flute canker-related defect is outlined which could be used both on standing trees during inventories and on logs prior to processing. A second assessment method for quickly checking the value of batches of sawn timber is also provided.
This new guide is designed to complement the 2009 Nectria field guide ‘The recognition and classification of Neonectria fuckeliana cankers’ which describes Nectria flute canker in young trees being assessed for pruning.
The new guide will is available as a download (pdf 8.8mb).
