Resin extraction consists of incising the outer layers of a pine tree in order to collect the sap or resin.
Resin circulates throughout a coniferous tree and a few others, and serves to seal damage to the tree. Harvesting pine resin dates back to Gallo-Roman times in Gascony.
Tapping pines may either be done so as to sustain the life of the tree, or exhaustively in the years before the tree is cut down.
In Gascony, and to a lesser extent in Provence, pine-tapping was practiced as a form of sharecropping, although uncertain status of the workers sometimes led to labor disputes.
Although almost abandoned during the 20th century, in Spain it has experienced something of a resurgence. Cesefor [1] is a Spanish non-profit foundation. which promotes forestry in Spain and its industry including Non-Wood Forest Products (NWFP) which in the Mediterranean region includes, resins, as well as cork, berries, nuts, and mushrooms, among many others.
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. Then, excess resin is collected.
The Douglas fir is an evergreen conifer species in the pine family, Pinaceae. It is native to western North America and is also known as Douglas-fir, Douglas spruce, Oregon pine, and Columbian pine. There are three varieties: coast Douglas-fir, Rocky Mountain Douglas-fir and Mexican Douglas-fir.
In polymer chemistry and materials science, a resin is a solid or highly viscous substance of plant or synthetic origin that is typically convertible into polymers. Resins are usually mixtures of organic compounds. This article focuses mainly on naturally occurring resins.
Turpentine is a fluid obtained by the distillation of resin harvested from living trees, mainly pines. Principally used as a specialized solvent, it is also a source of material for organic syntheses.
Palm wine, known by several local names, is an alcoholic beverage created from the sap of various species of palm trees such as the palmyra, date palms, and coconut palms. It is known by various names in different regions and is common in various parts of Africa, the Caribbean, South America, South Asia, Southeast Asia, and Micronesia.
Lacquer is a type of hard and usually shiny coating or finish applied to materials such as wood or metal. It is most often made from resin extracted from trees and waxes and has been in use since antiquity.
The stone pine, botanical name Pinus pinea, also known as the Italian stone pine, Mediterranean stone pine, umbrella pine and parasol pine, is a tree from the pine family (Pinaceae). The tree is native to the Mediterranean region, occurring in Southern Europe and the Levant. The species was introduced into North Africa millennia ago, and is also naturalized in the Canary Islands, South Africa and New South Wales.
Pinus pinaster, the maritime pine or cluster pine, is a pine native to the south Atlantic Europe region and parts of the western Mediterranean. It is a hard, fast growing pine bearing small seeds with large wings.
Pinus roxburghii, commonly known as chir pine or longleaf Indian pine, is a species of pine tree native to the Himalayas. It was named after William Roxburgh.
A bark beetle is the common name for the subfamily of beetles Scolytinae. Previously, this was considered a distinct family (Scolytidae), but is now understood to be a specialized clade of the "true weevil" family (Curculionidae). Although the term "bark beetle" refers to the fact that many species feed in the inner bark (phloem) layer of trees, the subfamily also has many species with other lifestyles, including some that bore into wood, feed in fruit and seeds, or tunnel into herbaceous plants. Well-known species are members of the type genus Scolytus, namely the European elm bark beetle S. multistriatus and the large elm bark beetle S. scolytus, which like the American elm bark beetle Hylurgopinus rufipes, transmit Dutch elm disease fungi (Ophiostoma). The mountain pine beetle Dendroctonus ponderosae, southern pine beetle Dendroctonus frontalis, and their near relatives are major pests of conifer forests in North America. A similarly aggressive species in Europe is the spruce ips Ips typographus. A tiny bark beetle, the coffee berry borer, Hypothenemus hampei is a major pest on coffee plantations around the world.
Naval stores are all liquid products derived from conifers. These materials include rosin, tall oil, pine oil, and terpentine. Crude gum or oleoresin can be collected from the wounds of living pine trees.
The naval stores industry produces and markets products derived from the oleoresin of pine trees, including rosin, tall oil, pine oil, and turpentine. It does this by collecting and processing organic forest products refined from slash pine and longleaf pine trees. The naval stores industry was associated with the maintenance of the wooden ships and sailing tackle of pre-20th century navies, which were caulked and waterproofed using the pitch of the pine tree.
Non-timber forest products (NTFPs) are useful foods, substances, materials and/or commodities obtained from forests other than timber. Harvest ranges from wild collection to farming. They typically include game animals, fur-bearers, nuts, seeds, berries, mushrooms, oils, sap, foliage, pollarding, medicinal plants, peat, mast, fuelwood, fish, insects, spices, and forage. Overlapping concepts include non-wood forest products (NWFPs), wild forest products, minor forest produce, special, minor, alternative and secondary forest products – for further distinctions see the definition section below
Rubber tapping is the process by which latex is collected from a rubber tree. The latex is harvested by slicing a groove into the bark of the tree at a depth of one-quarter inch (6.4 mm) with a hooked knife and peeling back the bark. Trees must be approximately six years old and six inches (150 mm) in diameter in order to be tapped for latex.
The Landes forest in the Landes de Gascogne, in the historic Gascony natural region of southwestern France now known as Aquitaine, is the largest man-made woodland in Western Europe. The French word, landes and Gascon lanas, mean 'moors' or 'heaths', from Transalpine Gaulish *landa ; compare Irish lann, Welsh llan (“enclosure”).
Fatwood, also known as "fat lighter", "lighter wood", "rich lighter", "pine knot", "lighter knot", "heart pine", "fat stick" or "lighter'd" [sic], is derived from the heartwood of pine trees. The stump that is left in the ground after a tree has fallen or has been cut is the primary source of fatwood, as the resin-impregnated heartwood becomes hard and rot-resistant after the tree has died. Wood from other locations can also be used, such as the joints where limbs intersect the trunk. Although most resinous pines can produce fatwood, in the southeastern United States the wood is commonly associated with longleaf pine, which historically was highly valued for its high pitch production.
Dioryctria sylvestrella, the new pine knot-horn or maritime pine borer, is a moth of the family Pyralidae. It is found in Europe, parts of Asia and North Africa. The adult is a small mottled brown and white insect with a wingspan of 28 to 35 mm. The moth flies in a single generation from June to October and is a pest of maritime pine and several other species of pine, on which the caterpillars feed.
Gum copal is a resin produced by the sap of forest tree in the genus Daniellia. Due to common impurities and differences in regions, gum copal ranges in color from black to yellow to white. Gum copal, along with ivory and slaves, was a significant export from East Africa in the 19th century. It can have an appearance similar to amber and may be mistaken for it. Unlike amber, gum copal is usually only 100–1,000 years old and it has not yet fossilized.
Fusarium circinatum is a fungal plant pathogen that causes the serious disease pitch canker on pine trees and Douglas firs. The most common hosts of the pathogen include slash pine, loblolly pine, Monterey pine, Mexican weeping pine, and Douglas fir. Like other Fusarium species in the phylum Ascomycota, it is the asexual reproductive state of the fungus and has a teleomorph, Gibberella circinata.
Resin workers were people whose work involved the extraction or working of resin, which was needed as a raw material in the manufacture of pitch, tar and turpentine. Resin work was an occupation that largely died out in the 19th and 20th centuries, but it was sometimes a primary occupation as well as a secondary source of income.
"Pecherei" is the common expression in southern Lower Austria for the practice of Resin Extraction from black pine trees (Evergreens). This profession centers around the extraction of tree resin, also known as "Pitch," that will ultimately be used in the production of further chemical products. Those who extract resin for a living are described as "Pecher" or "Resin Workers." In the year 2011, Pecherei was incorporated into the register of Intangible Cultural Heritage in Austria, which was drafted in the context of the UNESCO Convention for the Preservation of Intangible Culture.
