In order to get a better picture of where our ancient trees are, Exmoor National Park Authority have undertaken to locate and identify its ancient trees, including the 2006/7 Ancient Tree Hunt, which brought the total of known ancient and notable trees to well over 1700.
The data collected has been done so in line with that of the Ancient Tree Forum, so for recording purposes, to class as an ancient tree species such as oak, beech and ash should have a girth of at least 3.75m at Breast Height (1.5m) whereas species such as hawthorn, birch, rowan, willow and yew need only have a girth of 1.8m. Notable trees, considered to have exceptional value to conservation, culture or the landscape, have also been recorded even though they might not meet the criteria above.
The information from the Exmoor Ancient Tree Hunt is being uploaded to the website of the national Ancient Tree Hunt. Here you are able to use an interactive map to see where ancient trees have been recorded.
