It’s not just a tree felling, which itself is bad enough. If it is a tree where bats have their winter quarters, it has unfortunately happened many times before, that the trees were cut down including the bats inside the tree holes. Bats can not fly away like birds. Bats lower their body temperature during sleeping. Until they have warmed up their body back on normal temperature, it takes about 20 minutes. When a tree is cut and comes down, the animals have no chance to escape the deadly crash. The animals which survive are often seriously injured: broken bones, wing injuries, splinter deep in the body ... If no medical help is quickly there, the helpless animals die slowly and painfully. Emergency medical assistance requires that the company executing the tree felling, informs the regional advisor for bats immediately, then immediately a group of helpers and veterinarians can take care of the animals. The animals must be fed until recovery and they have to get flight training to get fit again. After recovery they have to be brought back to the location where they were found to be released back to the wild. (if it is not still winter, then the animals have to stay in the bat station to wait for spring so that they can look for new quarters – if available…). If the animals are back in the wild again, they didn’t only loose their quarter (of which there are less and less ...), but also their group-members. Bats are highly social animals and in working with injured animals, we can see again and again how the animals are chummy with each other. There are definitely friendships among individual animals and small groups in a large group. We even watched some bats grieving after group-members passed away. Here I can quote Noka: "As long as people think that animals do not feel, animals must feel that people do not think." I just wanted to give a brief look into the world of bats and show how important it is to maintain the old trees. - And this is only one aspect of "bats" – when a tree is cut, there are also owls, woodpeckers, insects and so on. An old tree is not just a tree, but a habitat for many animal species!
