The global decline of large old-growth trees and its impact on wildlife Anthropic alteration has attracted considerable interest globally and could lead to the loss of numerous wild species. In recent decades, approximately 10-40% of global species are facing a serious threat of extinction. Some believe that perhaps the sixth mass extinction is underway. Ross et al. 20183 described anthropogenic habitat loss as the leading cause of biodiversity loss on a global scale. According to the Committee on the Status of Endangered Wildlife in Canada (COSEWIC), “488 species are classified as extinct, extirpated, endangered, threatened or of special concern,” with habitat destruction being the most significant factor affecting threatens 84% of vulnerable species in Canada. . Because of its higher economic value, the loss of large populations of old-growth trees due to selective logging practices is classified as a major factor in habitat loss for several endangered species. 5. To reverse these losses it is essential to recognize the importance of large old-growth tree habitats, understand drivers of their decline and its impact on wildlife species that depend on them for nesting and feeding. This essay is the result of issues/controversies identified during the field visit to Haliburton Forest and Nature Reserve and will review the empirical literature on large, high-value old-growth trees and associated wildlife populations. The essay will also examine different management policies for protecting these giant remaining vertical habitats. Say no to plagiarism.

These giant vertical keystone structures play a key role in ecological functioning and provide a range of ecosystem services such as providing habitat or protective cavities for up to 30% of vertebrate species in some environments, providing sufficient food for large numbers of animals below form nectar, fruits, flowers and foliage, they help connect ecosystems by attracting pollinators and seed dispersers and providing nesting for numerous wild animals. These giant trees also sequester enormous amounts of atmospheric carbon, provide microenvironments for various species, and play a vital role in local hydrological functioning. The vital function of large, old-growth trees continues for hundreds of years even after the tree dies and provides nesting services for numerous species. The mature tree begins to produce a number of distinctive physical characteristics such as enormous amounts of coarse woody debris, organic matter, nesting cavities, burrows and roosting sites, and dead branches. The formation of large structures of ancient arboreal habitats takes hundreds of years. For example, it takes 120 to 220 years for cavities to form in the eucalyptus tree. These cavities/cavities provide key facilities such as feeding, nesting, shelter, escape from predators or hibernation for a significant number of taxonomic groups including vertebrates, invertebrates and mammals. The global status of large old trees facing multiple threats Large old trees are subject to a wide range of human-induced threats, such as forest clearing, developmentinfrastructure (highways, roads, residential projects, pipeline construction), logging and selective logging operations, agricultural land and grazing. According to the most recent estimates, out of a total of 3.04 trillion trees globally, 15 billion are cut down every year, indicating a critical reduction in the tree population of various genera, including large old trees. Interestingly, there may be key interactions between drivers that threaten large old growth tree habitats. For example, changes in land use such as forest fragmentation, logging, or selective logging can interact to increase the sensitivity of some habitats to deadly fires. Lindenmayer et al 201311, explained that in the mid-boreal forest of Sweden, large trees with a diameter at breast height (dbh) greater than 50 centimeters have all almost completely disappeared despite their large concentration in the forest a century ago. In North America, less than 1% of the distribution of dead large Douglas fir (Pseudotsuga menziesii) with dbh greater than 63.5 cm remains in logged areas. In Australia, due to the abundance of large old trees in the Mountain Ash Forest, a massive population decline is expected from an average of 5.1 large old trees/hectare at 1998 levels to an average of 0.6/hectare in next fifty years. In Amazonian Brazil, studies have predicted that 53% of large old trees with dbh greater than 60 cm have died in the last 30 years. In Canada, red pine trees (Pinus resinosa) found in Wolf Lake Forest Reserves are the largest old-growth conifers in North America and a key source of food for songbirds, chipmunks, mice, and chipmunks. However, pine trees are currently facing a looming threat from industrial, mining and logging activities, with only 0.6% of ancient red and white pine trees being intact and remaining in their range prior to European settlement in North America. York suggested that the removal of large trees is likely to create long-term negative impacts especially on wildlife and biodiversity and further argued that despite historical exploitation centered on the removal of large trees and their possible long-term harmful effects, cutting of these giants is still widespread in the United States. Vaillancourt et al. argued that in boreal coniferous forests, the presence of large tree structures is threatened by the current even-aged forestry system, so wildlife that depends on these habitats will also likely be affected by extensive logging operations. Furthermore, large old-growth trees are threatened by various other natural and unnatural factors such as fires, browsing by herbivores, drifting agricultural pesticide sprays, removal of trees in urban environments due to human safety concerns, several diseases and wasting syndrome. ancient trees The association of some wild species is so significant that the presence of large ancient trees serves as an economically advantageous alternative to their existence and abundance. In Australia, 42% of vertebrates and 28% of reptiles rely on large tree cavities. In the United States, John et al. In 2017, they studied the population of spotted owls (Strix Occidentalis) in territories that experienced massive logging of large trees compared to non-logged regions and found high owl population extinction rates when the owls' territories contained fewer of large trees (>61 centimeters dbh) and a tree cover (>70%), while a greater concentration of large trees leads to a.
