Horse chestnut survey time

posted on September 4, 2011

Across Europe horse chestnut trees are looking tired and ragged, and prematurely autumnal in colour, due to damage to their leaves by an insect: the horse chestnut leaf miner.

Now is the time to record whether trees near you have been infected by joining our TreeWatch project.  Help us record the spread of this pest and your data will be shared with scientists who want to find out more about the pest.

  1. Three of my own horse chestnut trees are heavily affected and several more in the Tubney area.
