The 100 Million Trees Project is a national Not-for-Profit initiative being run by Richard, David and Tina Mulcahy.

The project aims to see the planting of 100 million native Irish trees across the island of Ireland over the next decade, as a community-driven initiative to reverse the immense environmental damage caused by the reduction of forests worldwide and the loss of huge areas of biodiversity.

The project’s ambitious aim will be achieved through densely planting between 1000 and 2,500 native Irish trees at a time across small areas of land using ‘the Miyawaki method’.    By planting excess trees together these grow much faster, much more densely, create an area considerably more biodiverse and most importantly create a very rapid carbon sink. This inexpensive approach requires significantly smaller planting areas and can be carried out on unused or fallow land across Ireland.   Dense small plantations will help mitigate against large forest fires while at the same time provide excellent areas of biodiversity.  

We provide up to 15 species of native trees to suitable landowners and we also plant them using professional planters, all free of charge. We seek sponsorship from Corporations who wish to make a difference to communities, their clients and employees in order to have a better living environment for all.

You can help us make this project happen by making some land available for us to plant for you (from 600 square metre sites to 1024 square metre (1/4 acre) sites).
