Come up with a pantomime to explain what is it the restricted zone, special protection zone and reserve. Please see more information on the 1st information post.

Form groups of 4 to 5 people. See the drawing on the 1st information board, which introduces the development of mire. Each group receives a 5-meter piece of rope. Two members of the group start to spiral up and down (see the drawing), imitating the profile of the fen and bog with this movement. The group has two so-called spinners and at least one “bog jumper” and at least one shouter (who shouts whether the rope is in the fen or bog position). There are several groups that can be used to keep everyone engaged.

Take a piece of string (approx. 3.5 m) onto the group and together form an approximate contour of Estonia. Mark your location inside the outline of Estonia with a cone, pebble or another handy object.

Find the map of Estonia here, if needed.

Take a seat on the benches and discuss the content of the following sentences. Then put the sentences in reasonable order by writing down the appropriate sequence number for each sentence!

Imagine you want to start restoring the mire. Think about what you need to do for that! With the following, some activities related to open-bog restoration can be found in the sentences.

…. Find out and decide if it is necessary to remove the trees as it helps to raise water levels. Think about what to do with the chopped wood!

…. Find out how big the drainage area is.

…. Then start playing “with water” on your computer: click where it is wise to build dams that no more water would flow out of the drained mire.
