Because we live in the midst of constant change, we are in some ways blind to that change. Often we need long-term data to see the change.
How has your local landscape changed?
The Corine data only shows change over the past twenty years. Longer term change can be seen in old aerial photographs. For Helsinki, they are available here. Aerial photographs from the rest of Finland can be found in Finna using the search terms ilmakuva and the place name. Aerial photographs can also purchased from the National Land Survey of Finland (in Finnish).

Check the status of your nearest threatened habitat
Some habitat types have been changing more severely than others, and today we assess the threat level of entire habitat types in the same way we assess species. How close to your school can you find a threatened habitat type? How is it doing?
