is defined as Atypical stem growth subsequently influenced and modified by tropisms, i.e. gravitropism and phototropism, where reaction wood attempts to return it to a more typical habit or form.

In the image shown, the growth form of the tree at a juvenile age was modified with the result being that the tree was growing in one direction and then reverted to a more upright direction.

If you have any trees with a self-correcting lean other aspects that should be assessed with the tree include the structural root plate, the trunk for wounding or evidence of adaptive wood growth or internal decay, including fungal fruiting bodies. Trees with a self correcting lean but deemed structurally sound otherwise do not need to be removed, only when structural issues are identified that are likely to result in tree failure would a tree be considered to be removed.
