70-462: The West Coast Trail is open from May 1 until September 30 by reservation only. The West Coast Trail passes through the traditional territory of the Pacheedaht , Ditidaht , Huu-ay-aht , and Nuu-chah-nulth peoples, who have inhabited the area for more than 4,000 years. Native trails, used for trade and travel, existed in the area before European settlement. In the 1800s, Europeans began to use

140-418: A forest dynamics perspective, old-growth forest is in a stage that follows understory reinitiation stage. Those stages are: Of importance is that while the stand switches from one tree community to another, the stand will not necessarily go through old-growth stage between those stages. Some tree species have a relatively open canopy. That allows more shade-tolerant tree species to establish below even before

210-432: A biodiversity that is different from other forest stages. The characteristic topography of much old-growth forest consists of pits and mounds. Mounds are caused by decaying fallen trees, and pits ( tree throws ) by the roots pulled out of the ground when trees fall due to natural causes, including being pushed over by animals. Pits expose humus -poor, mineral-rich soil and often collect moisture and fallen leaves, forming

280-551: A boat, therefore she is there some days but away on a supply run on others. In July 2024 the Canadian Coast Guard announced plans to cease Lightkeeper operations on the two light stations located on the West Coast Trail. Citing geotechnical concerns and unstable ground, the Canadian Coast Guard announced plans to move the light keepers off site by winter 2024 and the heritage buildings will continue under

350-577: A different potential to store carbon. For example, this potential is particularly high in the Pacific Northwest where forests are relatively productive, trees live a long time, decomposition is relatively slow, and fires are infrequent. The differences between forests must, therefore, be taken into consideration when determining how they should be managed to store carbon. A 2019 study projected that old-growth forests in Southeast Asia ,

420-767: A different spatial location relative to the main canopy, hence each one receives a different amount of light. The mixed age of the forest is an important criterion in ensuring that the forest is a relatively stable ecosystem in the long term. A climax stand that is uniformly aged becomes senescent and degrades within a relatively short time to result in a new cycle of forest succession . Thus, uniformly aged stands are less stable ecosystems. Boreal forests are more uniformly aged, as they are normally subject to frequent stand-replacing wildfires. Forest canopy gaps are essential in creating and maintaining mixed-age stands. Also, some herbaceous plants only become established in canopy openings, but persist beneath an understory. Openings are

490-563: A healthy fungal ecosystem, and presence of indicator species. Old-growth forests are often biologically diverse , and home to many rare species , threatened species , and endangered species of plants and animals, such as the northern spotted owl , marbled murrelet and fisher , making them ecologically significant. Levels of biodiversity may be higher or lower in old-growth forests compared to that in second-growth forests, depending on specific circumstances, environmental variables, and geographic variables. Logging in old-growth forests

560-410: A moist, relatively mild climate, some old-growth trees have attained notable height and girth (DBH: diameter at breast height), accompanied by notable biodiversity in terms of the species supported. Therefore, for most people, the physical size of the trees is the most recognized hallmark of old-growth forests, even though the ecologically productive areas that support such large trees often comprise only

630-704: A result of industrial logging operations. In 2006, about 61,000 hectares of tall-eucalypt RFA old-growth forests remained unprotected. Recent logging attempts in the Upper Florentine Valley have sparked a series of protests and media attention over the arrests that have taken place in this area. Additionally, Gunns Limited , the primary forestry contractor in Tasmania, has been under recent criticism by political and environmental groups over its practice of woodchipping timber harvested from old-growth forests. Increased understanding of forest dynamics in

700-476: A result of this trespass on the traditional territory and cultural property of First Nations living in the area, hikers are now required to remain on the trail when passing through any Reserve areas. To accommodate the growing interest in off-trail historical sites, the Ditidaht First Nation now offers guided adventure tours through their traditional lands. Canadian Coast Guard Station Bamfield

770-550: A result of tree death due to small impact disturbances such as wind, low-intensity fires, and tree diseases. Old-growth forests are unique, usually having multiple horizontal layers of vegetation representing a variety of tree species , age classes, and sizes, as well as "pit and mound" soil shape with well-established fungal nets . As old-growth forest is structurally diverse, it provides higher-diversity habitat than forests in other stages. Thus, sometimes higher biological diversity can be sustained in old-growth forests, or at least

840-432: A severe disturbance, such as wildfire, insect infestation, or harvesting, is often called second-growth or 'regeneration' until enough time passes for the effects of the disturbance to be no longer evident. Depending on the forest, this may take from a century to several millennia. Hardwood forests of the eastern United States can develop old-growth characteristics in 150–500 years. In British Columbia , Canada, old growth

910-486: A source of raw materials. These services include making breathable air, making pure water, carbon storage, regeneration of nutrients, maintenance of soils, pest control by insectivorous bats and insects, micro- and macro-climate control, and the storage of a wide variety of genes. The effects of old-growth forests in relation to global warming have been addressed in various studies and journals. The Intergovernmental Panel on Climate Change said in its 2007 report : "In

980-412: A substrate for seedling trees. Intact soils harbor many life forms that rely on them. Intact soils generally have very well-defined horizons, or soil profiles . Different organisms may need certain well-defined soil horizons to live, while many trees need well-structured soils free of disturbance to thrive. Some herbaceous plants in northern hardwood forests must have thick duff layers (which are part of

1050-498: A tarp shelter. After 24 years, the burger shack run by Peter and Monique Knighton (the anglicized form of Nytom) had become a recognized and welcome stop on the West Coast Trail. Monique passed away on Dec 31st, 2017, at the age of 78. Barely 6 months later Peter, also 78, was killed when the boat he used to bring supplies in from Port Renfrew capsized in rough seas. Since 2022 - Nytom is now run by Katrina Knighton, grand daughter of Peter, who has to bring in supplies on her back instead of

1120-400: A thick organic layer that is able to nurture certain types of organisms. Mounds provide a place free of leaf inundation and saturation, where other types of organisms thrive. Standing snags provide food sources and habitat for many types of organisms. In particular, many species of dead-wood predators, such as woodpeckers , must have standing snags available for feeding. In North America,

1190-417: A useful number to measure. So, some forests may be excluded from being categorized as old-growth even if they have old-growth attributes just because they are too young. Also, older forests can lack some old-growth attributes and be categorized as old-growth just because they are so old. The idea of using age is also problematic, because human activities can influence the forest in varied ways. For example, after

1260-584: A very small portion of the total area that has been mapped as old-growth forest. (In high-altitude, harsh climates, trees grow very slowly and thus remain at a small size. Such trees also qualify as old growth in terms of how they are mapped, but are rarely recognized by the general public as such.) The debate over old-growth definitions has been inextricably linked with a complex range of social perceptions about wilderness preservation, biodiversity, aesthetics, and spirituality, as well as economic or industrial values. In logging terms, old-growth stands are past

1330-489: A view of the Pacific Ocean and Olympic Peninsula when the sea fog is not present. This fog offers a unique perspective as the beach and sky are clear, while the view just off shore is blocked. There are also numerous smaller campsites along the trail, with varying amenities, which can offer a quieter experience away from the often crowded main campsites. As 30 people may start the trail from each direction each day, it

1400-414: Is a contentious issue in many parts of the world. Excessive logging reduces biodiversity, affecting not only the old-growth forest itself, but also indigenous species that rely upon old-growth forest habitat. Some forests in the old-growth stage have a mix of tree ages, due to a distinct regeneration pattern for this stage. New trees regenerate at different times from each other, because each of them has

1470-669: Is affected. Climate change showed an impact on the mortality of some dominant tree species, as observed in the Korean pine . Climate change also showed an effect on the composition of species when forests were surveyed over a 10- and 20-year period, which may disrupt the overall productivity of the forest. According to the World Resources Institute , as of January 2009, only 21% of the original old-growth forests that once existed on Earth are remaining. An estimated one-half of Western Europe's forests were cleared before

1540-615: Is defined as 120 to 140 years of age in the interior of the province where fire is a frequent and natural occurrence. In British Columbia's coastal rainforests , old growth is defined as trees more than 250 years, with some trees reaching more than 1,000 years of age. In Australia, eucalypt trees rarely exceed 350 years of age due to frequent fire disturbance. Forest types have very different development patterns, natural disturbances and appearances. A Douglas-fir stand may grow for centuries without disturbance while an old-growth ponderosa pine forest requires frequent surface fires to reduce

1610-433: Is more accurate in forests where the species that constitute old-growth have long lifespans and succession is slow. Common cultural definitions and common denominators regarding what comprises old-growth forest, and the variables that define, constitute and embody old-growth forests include: Additionally, in mountainous, temperate landscapes (such as Western North America), and specifically in areas of high-quality soil and

1680-919: Is not the most commercially viable timber—in British Columbia, Canada, harvesting in the coastal region is moving to younger second-growth stands. A 2001 scientific symposium in Canada found that defining old growth in a scientifically meaningful, yet policy-relevant, manner presents some basic difficulties, especially if a simple, unambiguous, and rigorous scientific definition is sought. Symposium participants identified some attributes of late-successional, temperate-zone, old-growth forest types that could be considered in developing an index of "old-growthness" and for defining old-growth forests: Structural features: Compositional features: Process features: Old-growth forests provide ecosystem services that may be far more important to society than their use as

1750-438: Is not unusual to find many groups of hikers spending the night at any given main campsite. The trail is still extremely rugged and requires a high level of fitness, knowledge, and skill to complete, although in the last 10 to 15 years it has been upgraded to facilitate easier hiking and safety for those with less experience. This has changed the nature and challenge of the trail somewhat but has made it easier for hikers to explore

1820-557: Is seen as extremely economically unproductive, as timber can only be collected from falling trees, and also potentially damaging to nearby managed groves by creating environments conducive to root rot. It may be more productive to cut the old growth down and replace the forest with a younger one. The island of Tasmania , just off the southeast coast of Australia, has the largest amount of temperate old-growth rainforest reserves in Australia with around 1,239,000 hectares in total. While

The trail starts at Bamfield near Barkley Sound and runs south to Port Renfrew on Port San Juan Bay. In 1902, Bamfield became the North America terminus of the All Red Line 's Pacific submarine cable, which spanned the globe linking the British Empire. A trail was constructed to carry the line south to Victoria (and thence across Canada to link up with

1960-486: The Middle Ages , and 90% of the old-growth forests that existed in the contiguous United States in the 1600s have been cleared. The large trees in old-growth forests are economically valuable, and have been subject to aggressive logging throughout the world. This has led to many conflicts between logging companies and environmental groups . From certain forestry perspectives, fully maintaining an old-growth forest

2030-717: The Regional Forest Agreement (RFA) attempted to prevent the clearfelling of defined "old-growth forests". This led to struggles over what constitutes "old growth". For example, in Western Australia, the timber industry tried to limit the area of old growth in the karri forests of the Southern Forests Region; this led to the creation of the Western Australian Forests Alliance , the splitting of

2240-531: The biodiversity of the forested ecosystem . Virgin or first-growth forests are old-growth forests that have never been logged. The concept of diverse tree structure includes multi-layered canopies and canopy gaps, greatly varying tree heights and diameters, and diverse tree species and classes and sizes of woody debris. As of 2020 , the world has 1.11  billion   ha (2.7 billion acres) of primary forest remaining. Combined, three countries (Brazil, Canada, and Russia) host more than half (61 percent) of

3080-421: The economic optimum for harvesting—usually between 80 and 150 years, depending on the species. Old-growth forests were often given harvesting priority because they had the most commercially valuable timber, they were considered to be at greater risk of deterioration through root rot or insect infestation, and they occupied land that could be used for more productive second-growth stands. In some regions, old growth

In the 1970s, a lack of regulation resulted in hikers trespassing on culturally important and environmentally sensitive First Nations archaeological sites, such as villages and refuges on Reserve lands. As

3220-436: The forest will switch back to understory reinitiation stage. Using the stand dynamics definition, old-growth can be easily evaluated using structural attributes. However, in some forest ecosystems, this can lead to decisions regarding the preservation of unique stands or attributes that will disappear over the next few decades because of natural succession processes. Consequently, using stand dynamics to define old-growth forests

3290-472: The forests is vital to climate change mitigation . Old-growth forests tend to have large trees and standing dead trees, multilayered canopies with gaps that result from the deaths of individual trees, and coarse woody debris on the forest floor. The trees of old-growth forests develop distinctive attributes not seen in younger trees, such as more complex structures and deeply fissured bark that can harbor rare lichens and mosses. A forest regenerated after

This coarse filter approach to biodiversity conservation recognizes ecological processes and provides for a dynamic distribution of old growth across the landscape. And all seral stages—young, medium, and old—support forest biodiversity. Plants and animals rely on different forest ecosystem stages to meet their habitat needs. In Australia ,

3500-525: The late 20th century led the scientific community to identify a need to inventory, understand, manage, and conserve representative examples of old-growth forests with their associated characteristics and values. Literature around old growth and its management is inconclusive about the best way to characterize the true essence of an old-growth stand. A better understanding of natural systems has resulted in new ideas about forest management, such as managed natural disturbances, which should be designed to achieve

3570-620: The local Regional Forest Agreement (RFA) was originally designed to protect much of this natural wealth, many of the RFA old-growth forests protected in Tasmania consist of trees of little use to the timber industry. RFA old-growth and high conservation value forests that contain species highly desirable to the forestry industry have been poorly preserved. Only 22% of Tasmania's original tall-eucalypt forests managed by Forestry Tasmania have been reserved. Ten thousand hectares of tall-eucalypt RFA old-growth forest have been lost since 1996, predominantly as

The distance of the trail, whilst officially listed at 75 km, has not been changed or updated by Parks Canada for many years after being re-routed numerous times. Trail distance also changes depending on beach or forest travel, and some distance markers repeat themselves. GPS tracks from various hikers have put the true distance between 80 km and 92 km. Wildlife that can be encountered include cougars , black bears , wolves , hummingbirds , orcas , gray whales , seals , sea lions , and eagles . There are also abundant tidal pools on

4340-462: The soil has shown old-growth forests are more productive at storing carbon than younger forests. Forest harvesting has little or no effect on the amount of carbon stored in the soil, but other research suggests older forests that have trees of many ages, multiple layers, and little disturbance have the highest capacities for carbon storage. As trees grow, they remove carbon from the atmosphere, and protecting these pools of carbon prevents emissions into

Stand age can also be used to categorize a forest as old-growth. For any given geographical area, the average time since disturbance until a forest reaches the old growth stage can be determined. This method is useful, because it allows quick and objective determination of forest stage. However, this definition does not provide an explanation of forest function. It just gives

The trail passes old growth trees, waterfalls , streams and thick patches of deep mud. Along the coast, the trail includes sand and pebble beaches , headlands , and exposed shelf and boulders at low tide. The trail often diverts inland to avoid dangerous surge channels and impassable headlands, where cliffs descend straight into

4690-549: The understory reinitiation stage. The shade-tolerant trees eventually outcompete the main canopy trees in stem-exclusion stage. Therefore, the dominant tree species will change, but the forest will still be in stem-exclusion stage until the shade-tolerant species reach old-growth stage. Tree species succession may change tree species' composition once the old-growth stage has been achieved. For example, an old boreal forest may contain some large aspen trees, which may die and be replaced by smaller balsam fir or black spruce. Consequently,
