If this is not possible, the tree can be removed by a qualified arborist. The arborist will need to assess the size and location of the tree to determine the best method of removal. This may involve using a chainsaw to cut down the tree in sections, or using a crane to lift the tree out of the ground.
Once the tree has been removed, the stump should be removed as well. The stump can be removed by grinding it down below the surface of the soil, or by digging it out.
After the tree and stump have been removed, the area should be filled in with soil and replanted with grass or other vegetation.
