Gypsy moth life cycleProject Category: Emission Reduction

Project Description:

The Community Moth-Up is an event and communications campaign to raise awareness about the moth species Lymantria dispar dispar, also known as LDD moth and formerly known as the European Gypsy Moth, which is invasive to this region. There will be Community Moth-Up events throughout the summer and fall where small groups will be instructed to remove moth egg masses on trees in parks and ESAs across London. 

In addition to this friendly competition, the Community Moth-Up aims to educate Londoners about the gypsy moth through a communications campaign, including printed and digital ads. This project aims to educate Londoners and empower them to take hold of the moth invasion, which has been destroying native trees like the Oak. By saving trees and supporting additional tree planting in the community, the Community Moth-Up will help to keep London's urban forest healthy, thereby sequestering carbon emissions in the local area.

We are excited to share that the Community Moth-Up working group has been created so that conservation and environmental groups in London can work together to raise awareness and run moth-ups throughout the year!
