Aspen provides habitats for at least 2000 species
Asko Lõhmus, Ann Kraut, Piret Lõhmus, Jaanus Remm, Raul Rosenvald and Mihkel Soon introduce (old) aspen as a habitat for distinctively diverse and peculiar flora and fauna. Statistically speaking, 195 lichen species, about hundred moss species and 5 species of fungi have been found growing on aspen trees. Different insects (over 50 species of beetles, 6 species of butterflies and 3 species of sawflies) inhabit either the timber or bark of the tree. Cavities in the tree trunk offer nesting, resting or sheltering grounds for over 70 animal species, especially the woodpeckers. Even more species like dead aspen trees: 500-600 species of fungi, 45 species of lichens and mosses, over 500 insect species. Aspen forests create habitats for over 200 species of vascular plants.

The Tuhala Witch Well is endangered
Ants Talioja is in awe about the fact that an extensive limestone quarry is planned to be established only one kilometre from a nature protection area, the Tuhala landscape protection area which is protected for its karst features, including the famous Tuhala Witch Well. The plan is commented upon by hydrogeologist Hella Kink and botanist Ülle Kukk. They both agree that the plan threatens the protected landscapes and their flora and fauna a great deal.
