Thomas Hörren - LIFE IN DEADWOOD

The secret world of insects and other creatures

Few things are as diverse as deadwood. So much more than the remnants of old trees on the forest floor, it comes in an array of forms, providing habitats for insects and other organisms. Dead roots under the water, wooden coffins buried beneath the ground in urban spaces – this close interplay of decay and new life is all around us. If we look closely, we can see how the once-extinct beaver is now paving the way for other species, like the endangered saproxylic beetle. Deadwood also teaches us to have a positive outlook for our coexistence with local biodiversity, showing that there have already been a number of improvements in the past hundred years. An exciting journey through the secret world of insects, fungi and other creatures that live in the deadwood in our forests, parks and gardens.
