The mission of the Great Yew Hunt is to map the locations of ancient Yew trees across the UK and measure the girths of their trunks. The age of the Yew trees will then be estimated from looking at their girth measurements.
If you have an iPhone or Android Mobile--and an interest in tree hunting in the UK--you can help. Download the Epicollect application from iTunes (for iPhone users) or from the Android Marketplace (for Android Users). Once Epicollect has download, please load up the project 'YewHunting' and submit a photo and some basic information on the Yew tree you have found. This includes its Trunk girth measurement and the location in which the Yew tree has been found.
