1. Removal of a black pine tree in a garden

If forest trees are planted in gardens these trees can reach considerable sizes in a few decades thanks to for the most part good growing conditions and the missing competition. Trees that were valued in the beginning become a burden or even a danger.

In this case shading, loss of needles and cones and the formation of very high dead branches were the motivation for removing a solitary, 45 years old black pine tree (12 m high, DBH 65 cm(!)). Due to the lack of space the tree had to be removed as a whole instead of cut down. With the help of the great mass of fine branches a dampening pillow was made where the heavy parts of the tree could be thrown on to, saving time. Working time including the disposal: about 20 hours

2. Removal of spruces close to buildings

To remove two spruces close to buildings (8 m height, DBH 20 cm) a timesaving felling technique could be used because the neighbour plot was available for felling. Thanks to a special felling technique the garden fence remained untouched, the tree stem was cut at ground-level, the neighbour plot cleaned from sawdust and the trees were disposed of. Working time on site: about 4 hours.

3. Bit by bit removal of a willow tree overhanging public property

If there is no secure space for the conventional felling of a tree you have to remove the tree bit by bit. Here the branches are cut off and the tree removed bit by bit whereby the parts of the tree are either thrown down or lowered down on a rope according to circumstances.

In the example case the traffic safety of a pedestrian and bike way and respectively of a lane had to be secured. All tree parts of the willow (20 m height, DBH 35 cm) had to be lowered by rope. Working time on site: about 8 hours.

4. Removal of a plum tree including the root stock close to buildings

To remove trees in direct neighbourhood to buildings you need to take special care of risks and use suitable methods. If there is enough space for felling the tree is secured with ropes and cut down. If there is no space for felling the tree has to be removed bit by bit.

In the example case a plum tree (7 m height, DBH 30 cm) including the root stock should be removed. As there was enough space for felling the entire tree was pulled out of the ground with a winch timesaving in one piece. The tree lying on the ground could be quickly reduced to small pieces and disposed of. The former position was trimmed and cleaned. Working time on site: about 3 hours.

5. Removal of birch trees overhanging public property

If the secure space is smaller than necessary for conventional felling the tree has to be removed bit by bit to the required height before it can be cut down timesaving with conventional felling or with the help of a winch.

This technique was used for removing two birch trees (14 m height, DBH 30 cm) whereby timesaving was low due to small space and a branchy tree-top. Working time on site: about 8 hours.
