Features and characters of the individual

This remarkable black walnut tree grows in one of the small woods of Wolvendael Park. Discreet in spring and summer when its foliage blends with that of neighbouring trees, it attracts the eye in autumn when it is yellowed and its leaves and fruits cover the lawn. It is difficult to go under its crown because a barrier surrounds the group of trees. It prevents visitors from compacting the ground at the foot of the trees. Because when the soil is too compact, the roots lack water and air. Behind the barriers, a layer of plants and fungi can develop, and dead leaves can decompose slowly. This forest-type soil is better for trees: it gives them more strength and extends their life expectancy.
