Climate Change and Biodiversity in Baden-Württemberg

Global | regional | local


Factors influencing biodiversity in Baden-Württemberg

  • higher average temperatures
  • earlier start of vegetation & longer growing season
  • nutrient and pollutant loading
  • Occurrence of invasive species
  • Land use change
  • Overuse of natural resources


Climate change & Stuttgart

  • Preserving biological diversity is one of the greatest challenges of our time. Currently, a dramatic extinction of species can also be observed in Baden-Württemberg. About a quarter of all animal and plant species studied are threatened with extinction. In the next few decades, one million species of the world's eight million animal and plant species could simply disappear. The loss of biodiversity threatens the livelihoods of us all.

Monitoring as a solution

What does monitoring mean?

  • Long-term coverage of diversity within and among species, as well as diversity of habitats interacting as communities of plants, animals, and microorganisms, and their non-living environment.
  • Examples of parameters to be surveyed: occurrence of invasive species, insect populations, distribution of breeding birds, etc.

Benefits and opportunities:

  • Showing long-term correlations and changes
  • Enables forecasts
    → Timely response to extreme events
    → Development of new adaptation strategies, early warning systems, etc.

Participatory role of climate detectives - biodiversity monitoring using apps


iNaturalist App (

  • social network, based on the concept of mapping and sharing observations of global biodiversity
  • Observations can be made using photos or sound recordings
  • Identification of plants and animals in the environment using the app recommendations
  • Recording of data and making it available to other users
  • Providing public access to the data by posting it on the iNaturalist website


Use of the iNaturalist app (detailed in the guide)

  • Take a photo or audio recording of the plant or animal and upload it.
  • Identify plant or animal based on suggestions.
  • Add further information about location etc.
  • Submit data.


The ParKli project on iNaturalist

Join the ParKli project on iNaturalist to collect observations in the Stuttgart area as a team and to bundle them better.

Go to the following link >>, log in with your access data and join the project.


Why do we want to collect data in ParKli using the app?

  • We need a good database on the current state of our local environment.
  • Together with you, we would like to go on a search for clues and use the iNaturalist app to collect data on the state of local biodiversity.  
  • This data basis should make it possible to jointly develop and actively implement local measures for adaptation to climate impacts.
