Resin is usually collected by causing minor damage to the tree by making a hole far enough into the trunk to puncture the vacuoles, to let sap exit the tree, known as tapping, and then letting the tree repair its damage by filling the wound with resin. This usually takes a few days.

Natural bitumen pitch, from the tar pit above the McKittrick Oil Field, Kern County, California. Pitch is a viscoelastic polymer which can be natural or manufactured, derived from petroleum, coal tar, [1] or plants.
The most important tree for use in resin extraction is the black pine (Pinus nigra), which has the greatest resin content of all of the European coniferous trees, and it was even used as early as by the Romans for this very purpose. [2] These trees are generally best tapped for their resin between the ages of 90 and 120 years old.
Fusarium circinatum is a fungal plant pathogen that causes the serious disease pitch canker on pine trees and Douglas firs (Pseudotsuga menziesii).The most common hosts of the pathogen include slash pine (Pinus elliottii), loblolly pine (Pinus taeda), Monterey pine (Pinus radiata), Mexican weeping pine (Pinus patula), and Douglas fir.

Pine tar is a form of wood tar produced by the high temperature carbonization of pine wood in anoxic conditions (dry distillation or destructive distillation). The wood is rapidly decomposed by applying heat and pressure in a closed container; the primary resulting products are charcoal and pine tar .
Longleaf pine seeds are large and nutritious, forming a significant food source for birds (notably the brown-headed nuthatch) and other wildlife. Nine salamander species and 26 frog species are characteristic of pine savannas, along with 56 species of reptiles, 13 of which could be considered specialists on this habitat. [16]
