Can prescribed burning improve resin yield in a tapped Pinus pinaster stand?

The secretory structures were more numerous in burned + tapped trees than in tapped only trees in 2016, which could lead to higher resin yields in subsequent years. However, there were no differences in resin yields in relation to treatments in the period of study (2015-2016). Prescribed burning alone did not cause significant anatomical variations in Pinus pinaster. More extensive studies are required to evaluate the use of prescribed burning as a management tool for resin extraction, an activity of importance in rural development strategies.
