[1] [3] Where tree stumps are unavailable a more modern, angular look can be achieved by using railway sleepers or old oak floorboards and some companies sell waste timber or driftwood specifically for the purpose of constructing stumperies. [2] Plants such as ferns, mosses and lichens are often encouraged to grow around and on the stumpery. [2]
Tree stump, about 37 years after falling. After a tree has been cut and has fallen, the stump or tree stump is usually a small remaining portion of the trunk with the roots still in the ground.

The stump is the base of the trunk and the attached woody roots. Tree stumps and roots are extracted using a hydraulic head on a tracked excavator or with a mechanical head equipped by a special tool for tractors. Stump harvesting is expected to provide an increasing component of the woody material required by the woody biomass power sector in ...
