Jizera Mountains in Central Europe in 2006 Tree dieback because of persistent drought in the Saxonian Vogtland in 2020. Forest dieback (also "Waldsterben", a German loan word, pronounced [ˈvaltˌʃtɛʁbn̩] ⓘ) is a condition in trees or woody plants in which peripheral parts are killed, either by pathogens, parasites or conditions like acid rain, drought, [1] and more.
Kauri dieback is a forest dieback disease of the native kauri trees (Agathis australis) of New Zealand that is suspected to be caused by the oomycete Phytophthora agathidicida. [1] Symptoms can include root rot and associated rot in a collar around the base of the tree, bleeding resin, yellowing and chlorosis of the leaves followed by extensive ...
Dieback may refer to a number of plant problems and diseases including: Forest dieback caused by acid rain, heavy metal pollution, or imported pathogens; The death of regions of a plant or similar organism caused by physical damage, such as from pruning; Those caused by the genus Eutypa, such as Eutypa dieback
A woman washes her shoes to reduce the spread of kauri dieback disease in Waipoua Forest. Kauri dieback was observed in the Waitākere Ranges caused by Phytophthora cinnamomi in the 1950s, [41] again on Great Barrier Island in 1972 linked to a different pathogen, Phytophthora agathidicida [42] and subsequently spread to kauri forest on the ...
In Australia, where it is known as phytophthora dieback, dieback, jarrah dieback or cinnamon fungus, Phytophthora cinnamomi can infect thousands of native plants, causing damage to forests and removing habitats for wildlife. [12] [13] [14] Several native plants are at risk of extinction due to the effects of the disease. [12]
Sustained warming of the northern high latitudes as a result of this process could activate tipping elements in that region, such as permafrost degradation, and boreal forest dieback. [3] Thawing permafrost is a threat multiplier because it holds roughly twice as much carbon as the amount currently circulating in the atmosphere. [ 6 ]
The Kyoto Protocol article 3.3 thus requires mandatory LULUCF accounting for afforestation (no forest for last 50 years), reforestation (no forest on 31 December 1989) and deforestation, as well as (in the first commitment period) under article 3.4 voluntary accounting for cropland management, grazing land management, revegetation and forest ...
Forest inventory is the systematic collection of data and forest information for assessment or analysis. An estimate of the value and possible uses of timber is an important part of the broader information required to sustain ecosystems .
