To restore original natural dynamics in streams many measures are necessary. In the 'Leuvenumse beek,' a nature organization tried to increase heterogeneity of the river bottom and water retention by putting dead wood in the stream system. In autumn and winter when rainfall is high, parts of the forest get flooded. Once I saw this little beech in the water trying to survive under these harsh conditions. I returned sometimes to this place to take pictures. One evening all the conditions were satisfactory.
