The mature trees were felled in Rosendal over the winter. But now the foresters are back to clear all the branches. They have worked for several days to take away all the "litter".
And here is the massive pile of branches and half-rotten wood left behind. It will be left to dry out for several months and presumably one day they will come back and put it all onto trucks and take it away. This kind of wood can be transformed into pellets (which are burned for energy).
