5) Tree Microhabitat Catalogue

 The catalogue offers an accessible typology for identifying small and valuable structures for biodiversity. It was developed by a experts and serves as a field guide. The vast array of existing tree microhabitats (TreMs) is subdivided into a few concise categories of saproxylic (cavities, injuries and wounds, bark, deadwood) and epixylic (deformations, epiphytes, nests) structures that can serve as shelter or home for different flora and fauna. TreMs are input for elaborating a habitat value for each tree in a Marteloscope. This information can be retrieved in the course of field exercises using the I+ software. It is available in the following languages:


Czech, Danish, Dutch, English, Farsi, Finnish, French, German, Hungarian, Italian, North Macedonian, Portuguese, Romanian, Slovenian, Spanish, Turkish and Ukrainian

6) The tree microhabitat catalogue App

The phone App was developed as a mobile field support for identifying biodiversity relevant tree microhabitat structures. Its content mirrors the tree microhabitat catalogue and is currently available in the following languages: Czech, English, Finnish, French, German, Italian, Portuguese. The App is freely available and runs on Android and Apple devices.
