Locate a 50 x 10 cm area on each of the three aspects of the tree between 1.0 and 1.5 m above ground level.
For each trunk record the circumference.
For each aspect (East, West, South) select the lichens you can identify. Use the ‘info’ button to help with identification. Then click the next aspect (top right). Go through to ‘Finish’, then start the next trunk (top right ‘Trunk 2’).
Complete all 5 trunks then you can move to the branches.
Choose 3-5 branches on the same tree species (oak or birch) as used in the trunk survey. Do not use fallen branches.
If there are no suitable branches on these trees, branches from other nearby trees of the same species can be used.
Choose branches in an open aspect and within easy reach.
For each branch record the lichens in each Zone (1,2,3) represented by approximate distances along each main branch, measured from the growing tip.
You may have to modify these zones depending on the growth form of the trees that you are using. Use the ‘info’ button to help with identification. Then click the next zone (top right). Go through to Finish, then start the next branch (top right ‘Branch 2’).
Complete all 5 branches.
