Short summary
Chemotaxonomic identification of keystone plant species in the Bale Mountains are possible using lignin phenols. However, Erica could not be differentiated chemotaxonomically from all other investigated plants using n-alkanes. Unambiguous characteristic patterns of lignin phenols reflected in the plant samples were not sustained in the organic layers and mineral topsoils. This is due to degradation and organic matter inputs by roots. Therefore, the past extent of Erica is still speculative.
