Tree sitting is a form of environmentalist civil disobedience in which a protester sits in a tree, usually on a small platform built for the purpose, to protect it from being cut down (speculating that loggers will not endanger human lives by cutting an occupied tree). Supporters usually provide the tree sitters with food and other supplies.
Tree sitting is often used as a stalling tactic, to prevent the cutting of trees while lawyers fight in the courts to secure the long-term victories.
Tree-sitters in trees claimed by Pacific Lumber in Humboldt County have been subject to forced removal by hired 'extractors'. The practice started with a single extractor in the late 90’s but in 2003 Pacific Lumber hired teams of climbers to remove dozens of tree-sitters, particularly in the Freshwater area East of Eureka, California.
List of tree sits
Some of the more notable tree sittings include:
- Tree sitting in 1978 (the first tree sitting action) led to the protection of what is now the Pureora Forest Park in New Zealand.
- Mikal Jakubal was an early American tree sitter. On May 20, 1985 he ascended a Douglas Fir in an area of the Middle Santiam region of Willamette National Forest that was in the process of being clearcut. While short-lived, his tree sitting action inspired a group tree sitting event by Earth First! activists that lasted from June 23 to July 20, 1985, when two Linn County, Oregon sheriff's deputies wrestled Marylander Ron Huber from his tree after a day-long stand-off.
- Native Forest Action used tree sitting during its campaign to save the West Coast, New Zealand native forests. In April 1997, the logging company, Timberlands West Coast Limited destroyed one of the sites by deliberately swinging a tree from a helicopter into it without ensuring that it was fully clear of protesters. The CAA cleared the helicopter pilot of wrongdoing in a controversial judgment that appeared to have been interfered with, according to leaked internal documents.
- Julia Butterfly Hill, an activist in Humboldt County, California became known for her 738-day sit (from December 10, 1997 until December 18, 1999) in a 180-foot (55 m), 600-year-old Coast Redwood tree she named Luna. Eventually, Hill and other activists raised $50,000 to spare her tree and a 200-foot (61 m) buffer around it.
- In 2002, two US environmental activists involved in tree-sitting protests died in separate accidents.
- In 2004, activists from Greenpeace and the Australian environmental organization The Wilderness Society hold the record for the world's highest tree-sit at 65m, in the Styx Valley, Tasmania. Peter (Peck) Firth spent 51 days up a giant Eucalyptus tree nicknamed Gandalf's Staff.
- In 2004, at least six tree sits were erected in Tuart trees at Ludlow Tuart Forest near Busselton in South Western, Western Australia.
- In 2006, two sits were built in Jarrah (Eucalyptus) trees at "Arcadia" Jarrah Forest near Collie in South Western, Western Australia. Two activists were removed and arrested but one had his charges dropped and the other went to court and was acquitted.
- In May 2006, protesters at Titnore Wood began a tree-sitting campaign against a major urban extension to the town of Worthing in West Sussex. Around 25 protesters created tree-houses and a network of tunnels. In March 2010, after nearly four years of tree-sitting, the local council voted unanimously to turn down the application for development.
- In 2006, 2007, and 2008, protesters in Berkeley, California sat in coast live oak trees to prevent the construction of a new sports facility by the University of California, Berkeley. On September 5, 2008, the University began logging the grove, after winning court agreement. Four days later, after a little more than 21 months, the final four tree sitters surrendered to authorities, ending the longest running urban tree-sit in history.
- In 2000 after two years living in Mariah, a thousand-year-old tree, Nate Madsen descended. Both Pacific Lumber (PL) and the California Department of Forestry (CDF) signed off on the timber harvest plan, which means protection for Mariah for the moment. PL can still file another plan, but for now, Mariah seems safe. 
- In 2008, a tree sit was constructed in College Grove (remnant bushland), Bunbury, Western Australia and was removed after being occupied for three months. Another was promptly constructed nearby in the next stage that was threatened by housing development; it included a functional trampoline.
- In 2009, there are ongoing tree-sits in Humboldt County, Ca. to prevent logging of 100+ year old redwoods by Green Diamond (formerly known as Simpson). One of the tree-villages is defending the territory of an active Spotted Owl mating pair.
- In 2009, on August 25 two protesters with Climate Ground Zero halted blasting above Pettry Bottom in Raleigh County, West Virginia. Laura Steepleton and Nick Stocks climbed 80 feet in two trees in direct protest of Massey Energy's mountaintop removal mine. The trees were located within 30 feet of the Edwight mine, and within the 300 feet of blasting. Kim Ellis and Zoe Beavers were arrested for providing direct support, only to return later that afternoon at the behest of state police to serve as liaisons for the sitters. Kim Ellis and Zoe Beavers were then asked to leave the site at 5:30pm by mine security only to refuse and get arrested again by state police at 7:30pm. The tree sit halted blasting for six days while facing harassment from miners including threats of rape, trees being felled in close proximity, and chainsaws partially cutting the trees the sitters occupied.
- In 2009, environmental activists from the Still Wild Still Threatened group in Tasmania, Australia were forced down from tree sits in the Upper Florentine Valley by police acting in conjunction with Forestry Tasmania in two separate busts in January and May.
- In 2010, on January 20 three protesters associated with Climate Ground Zero and Mountain Justice halted blasting on a portion of Massey Energy's Bee Tree mountaintop removal mine on Coal River Mountain, West Virginia by ascending three trees, two tulip poplars and an oak tree. David Aaron Smith, 23 Amber Nitchman, 19 and Eric Blevins, 28 were on platforms approximately 60 feet up in direct protest of mountaintop removal mining and blasting near the Brushy Fork Coal Impoundment. Joshua Graupera, Isabelle Rozendaal, Bernard Fiorillo and David Baghdadi were also arrested for providing ground support. The tree sit halted blasting for nine days. A federal judge granted a permanent injunction to Marfork Coal Co. Inc., a subsidiary of Massey Energy, ordering the defendants to keep off all company property.
- In 2011, on July 20 two protesters associated with the RAMPS Campaign halted blasting on a portion of Alpha Natural Resources Bee Tree mountaintop removal mine on Coal River Mountain, West Virginia by ascending two trees, a tulip poplar and an northern red oak tree. Catherine-Ann MacDougal, 24, and Becks Kolins, 21, were on platforms approximately 80 feet off the ground within 300 feet of active blasting on the mine in direct protest of mountaintop removal mining. Becks Kolins stayed on their platform for 14 days while Catherine-Ann MacDougal remained for a total of 30 days making this the longest tree sit east of the Mississippi River. Elias Schewel and Junior Walk were arrested immediately for providing direct support on the ground. Criminal cases are still pending for the two sitters, while a civil suit seeking compensatory and punitive damages is pending for all four activists.
- In 2011, on December 14, Miranda Gibson climbed up a 60m old-growth Eucalyptus delegatensis tree in the heart of Tasmania’s southern virgin rainforest. Gibson vowed to stay until the forest is protected. The area was imminently due to be logged, despite being part of the area supposed to be protected under the fraught Forests Intergovernmental Agreement (IGA). She was forced down from the tree 15 months later due to a bushfire.
A tree village is an extension of the tree sitting protest, involving several tree houses. The "Fern Gully" in Northern California lasted over 20 years, ending in 2008 with agreement not to fell the stand of old growth redwood trees.
In the United Kingdom permanent tree houses are common. One treehouse, BattleStar Galactica at the Manchester International Airport, held 12 people. Permanent tree-houses can be occupied for a year or more. They often have lock-on points for protesters to chain themselves to during evictions. Tree houses have also been used at Newbury bypass, Crystal Palace and Epsom.
