First, the DBH of the stump is not big, 40-50 cm. It is not uncommon for many trees to reach this DBH.
Second, this stump should be the stump of eucalyptus. Eucalyptus contains chemicals that inhibit the growth of plants, and the growth of plants planted in it is inhibited.
Third, the shape of this stump is too general.
Fourth, the stump has not been treated with antiseptic, the color is not good, and it will rot after a year, so the eucalyptus can grow a little longer.
To sum up, I'll give you an appraisal of 200 for this stump.
