Influence of climate variables on resin yield
StarTree partner, Sven Mutke, is co-author on a new paper published in the journal Agricultural and Forest Meteorology: "Influence of climate variables on resin yield and secretory structures in tapped Pinus pinaster Ait. in central Spain".
The main practical findings of the study, developed in collaboration with the Regional Forest Technology Centre and local stakeholders (a resin tapping cooperative), were that variation in resin yield and resin canal abundance were correlated with tempera-ture and water deficit in spring. Under adverse climate scenarios where resource optimization is desirable, a educed tapping season during the warmest months (June–September) would be advisable, assuming avery small production loss. Similarly, in years with a rainy summer and/or dry spring, a slightly longer tapping season could be suggested, as resin yield increases after these events.
The study was funded by the Spanish Ministry of Agriculture, Food and Environment as part of the European Cooperation project REMASA for the improvement of the resin sector in rural areas, and the European project StarTree "Multipurpose trees and non-wood forest products a challenge and opportunity", funded by the European Union through the European Commission's FP7 Cooperation Work Programme under grant agreement no. 311919.
