The discussion revolves around the UK's Ancient Tree Inventory (ATI), which catalogs significant trees across the country. Recent events, like the uproar over the Sycamore Gap tree's removal, underscore varying public sentiments regarding tree preservation. While the Sycamore Gap tree garnered substantial attention despite being only 150 years old, a contrast is drawn to less public reaction concerning the removal of much older trees. Commentary emphasizes the inconsistency in public outrage and the need for greater awareness and action regarding ancient trees and their preservation. Additionally, OpenTrees.org is pointed out as a valuable resource for municipal tree data, although there are usability issues.
