On 29 November, within the Iberian cooperation of the RN21 Integrated Project, a technical visit took place in Plasencia, Spain, involving UTAD, RESIPINUS and CoLAB ForestWISE. The trip offered first-hand insight into resin-tapping and transformation practices across the border and strengthened the exchange of knowledge between Portugal and Spain — the two countries holding the largest maritime-pine area in Europe — in a logic of joint valorisation of the Iberian Natural Resin chain.
