The document discusses the pine forest in Leiria, Portugal and the exploitation of resin as an important economic activity there. Resin is formed in certain plants like conifers through wounds in the bark and hardens when exposed to air. It can also be obtained by butchering the bark or wood. Hard resins are used for coatings and cement while softer resins containing oils are used for therapies and incense. The pine forest is home to new pines sprouting and some insects.
