Pine tapping techniques used around the world for resin production differ widely, both in terms of methodology and pine species tapped. Results obtained in comparing three commercial operations in China, Brazil and Indonesia showed that it is possible to improve tapping operation yields in terms of labor efficiency and amount of pine trees tapped per year. Further developments are needed to establish more sustainable tapping operations, essentially based on detailed understanding of how pine trees produce resin. These advances may result in reduced interventions per season and mechanization of some of the activities, which could be coupled to the selection and propagation of pine species and individuals that show higher resin yield.

The Brazilian wood biomass supply and utilization focusing on eucalypt2014 •
The forest plantations are replacing the native forest in the wood provision for industries. At world-wide level almost 50% of the provision comes from plantations (IUFRO, TAIPEI 2007), being much greater in the South Cone of South America. Specially in Argentina, Chile and Uruguay the plantations provide more than 85 % of the industrialized raw material. The most important plantations in the South Cone are pines and eucalyptus, having the latter, highest growth (over 30 m3/ha/year, being able surpass 50 m3/ha/year). Eucalyptus initially was planted for energy, cellulose and boards, but in the last years has been adapted for solid uses, replacing in several cases native wood. For this reason, it began to have special importance in Brazil, Chile, Argentina, Uruguay and Paraguay the genetic, silviculture and technological properties uses of this wood. The present paper shows the results of referred studies on technological properties of the fast growth eucalyptus wood, at usual cut ag...

Effect of four tapping methods on anatomical traits and resin yield in Maritime pine (Pinus pinaster Ait.)2016 •
European Journal of Forest Research
Resin tapping influence on maritime pine growth depends on tree age and stand characteristicsResin is a renewable forest resource that can increase the economic value of some forests in rural areas. Resin production is associated with climatic conditions. However, its impact on trees’ growth remains unclear. Here, we studied radial growth in six Portuguese Pinus pinaster forests that had been resin tapped for 5–7 years along a latitudinal and climatic gradient to understand whether resin tapping affects tree growth, and how it is affected by climate, stand and tree traits. Tree-ring width (TRW) on tapped and untapped trunk sides was compared before and during the tapping period. Tree-ring width decreased in the three youngest populations (< 30 years), with no changes in older populations (> 40 years), while TRW increased after resin harvesting began in the oldest stand (> 55 years). Annual resin-tapping impact (RTI), calculated as the ratio between TRW during tapping years and the 5-year average TRW before tapping, was below and above 1 in the younger and older sta...
