Understanding the logic of obtaining, managing and perceiving of local natural resources, particularly plants, is crucial for ensuring the sustainability of human life, as the use of plants is a key for the survival of humans. Use of plants is part of complex human culture – local ethnobotanical heritage, specific to place and people inhabiting the place. Ethnobotanical knowledge is very practical: one needs to be able to recognize the plants in order not to pick up the wrong one, to know exactly how to cook, to prepare the medicine, to build the roof. This practical knowledge is not static but constantly changing and adapting to new ecological, social, cultural and political conditions to meet the needs of the society. We want to understand the dynamics of knowledge transmission and the influence of specific factors on the changes of local ecological knowledge. Evidences of these processes are large high dimensional datasets with complex dynamic structures. We will discuss different ways of data analyses and models to identify the most influent factors of the changes in utilization of local ecological resources.
