Actual Projects


Flora Incognita - interactive plant species identification with mobile devices

Flora Incognita is a research project founded by the Federal Ministry of Education and Research (BMBF), the Federal Ministry of Environment, Nature Conservation, Building and Nuclear Safty (BMUB), the Federal Agency for Nature Conservation (BfN) and the Nature Conservation Foundation of Thuringia, with the purpose to support research projects to implement the German National Strategy on Biological Diversity.It is a joint project between the Technical University in Ilmenau and the Max Planck Institute for Biogeochemistry in Jena.

Aim/Objectives

  1. Developing an interactive and incremental method for the semi-automated identification of plant species
  2. Creating a repository of the wild flowering plants of middle Germany customized to specifics of automated recognition
  3. Developing didactically optimized user interactions and species information within the identification process
  4. Developing an automated field mapping system for the identified plant species and their registration within central databases of the Nature Conservation authorities

On the project website you will find information on the Flora Incognita organization, the latest news and how to join Flora Incognita activities. http://floraincognita.com/


Research Interests:

  • Computer vision applied for plant species identification
  • Historical forest use and management, land-use change
  • Automated monitoring methods vor conservation
  • App design and user experience
  • Project management and administration
