All the trees planted by Clean Air are carefully managed; they're not just planted and left to fend for themselves. They are only planted with nature reserves/community woodlands, which are just as keen as us and you for the trees to survive and live to maturity. Hundreds of volunteers, working with the nature reserves/community woodlands, help look after the trees at the sites across the UK. On sites with rabbits, voles, or deer, the trees are planted in protective shelters to improve the chances of each tree's survival.   Each woodland is visited annually to ensure the trees are doing well, and recent photos of the woodland are posted to the EForests website to show how they're thriving.   The first few years are the most critical to a tree's survival, and any damaged/dying trees are replaced within the first 5 years.
