A stump grinder is used to remove the remaining stump of a felled tree. This will grind the stump and major roots. The removal of tree stumps improves the aesthetic and allows for structures to be built in this location.

However if the stump is not accessible then ECO plugs are used. They degrade the stump and stop the regrowth of the root system in an environmentally friendly manor. Although the stump will remain in place, no further growth can occur.
