With the plea, “Help us to find and map all the old, fat trees across the UK,” the Ancient Tree Hunt seeks to merge antique and modern mapping to identify and protect ancient trees across the United Kingdom. Historic maps ranging from 1843 to 1893 have been overlayed onto modern geospatial data in an effort to identify the location of historic trees. The site invites interested participants to use the interactive map to identify areas from the historic maps that contained trees. Volunteers can then take that geographic information and head into the countryside to find and survey ancient trees.
