Ancient and Veteran Trees
About Ancient and Veteran Trees
Ancient and veteran trees are ecologically important species, which can indicate past land management practices. Different species of tree gain ancient status at different ages for example, oak trees are a long-lived species, so they do not reach ancient status until 400 years old. Ancient trees are not common within woodlands where there is competition for light and nutrients therefore, they are normally found in open spaces and woodland edges. Ancient trees provide a consistent habitat over long periods of time, which is important for a number of flora and fauna species. Many fungal species are associated with this long-lasting habitat continuity.
Veteran trees are important because of their age, ancient characteristics, ecology, aesthetics or cultural importance. Veteran trees can be any age, but they must show ‘ancient characteristics’ whereas, ancient trees are determined by age and are all classed as veteran trees. According to the Woodland Trust Ancient Tree Inventory (2022) there are approximately 340 ancient trees in vicinity of the Great Glamorgan Way.
Deadwood Habitat
To provide the most value as a habitat standing deadwood (i.e. a dead tree or branch which is still in place) should be left in situ. Deadwood, decaying bark and complex roots associated with ancient trees provide important habitat for a diversity of fungi, mosses, liverworts and lichen. Parmelia minarum is a rare lichen found on ancient Beech and Oak trees. The deadwood, fungi and lichen can support a wide range of invertebrates, especially wood-boring beetles and flies. Endangered species include Moccas beetles and stag beetles.
Woodland Birds and Bats
Veteran and ancient trees provide important habitat for many woodland bird species. Cracks and crevices which form in the bark with age, form suitable nesting sites. The crevices also provide important roosts for many bat species.
The diversity of invertebrates living within the tree bark, and it’s associated fungi and lichen, provide a food source for woodland birds and bats.
