New Rules for Old Trees - Dispute over Species Protection in the Forest - Hesse's Forest Policy Cuts Habitat Trees in Half, Sparking Outrage

New rules for Hesse’s state-owned forests now allow only an average of five habitat trees per hectare to remain until natural decay. This replaces the previous requirement of 10 to 15 such trees per hectare. The change has sparked criticism from conservation groups. Habitat trees are often ancient and decaying, providing vital refuge for endangered species. Woodpeckers, owls, bats, hazel dormice, and beetles rely on them for survival. Cracks in bark, dying branches, and deadwood create microhabitats essential for insects. Woodpeckers carve nesting cavities in mature trees, which later shelter other cavity-dwelling animals.

Beech trees, for example, can live up to 300 years but are often felled at around 140 years. This practice cuts short critical aging and decay phases that support biodiversity. The Hessian Ministry of Agriculture defends the new regulation, claiming it aligns with European protected area criteria and reduces administrative burdens.

NABU Hesse criticises the halving of habitat tree numbers. The group argues for preserving successor trees to ensure species can recolonise areas. Nils Stanik of the Hessian Society for Ornithology and Nature Conservation calls the revised rule deeply problematic, stating it weakens nature conservation in Hesse’s state forests. The new regulation reduces the required number of habitat trees in Hesse’s forests. Conservationists warn this will diminish biodiversity by removing critical habitats for many species. The state maintains the change simplifies management while meeting European standards.
