Why are there only a few different kinds of plants in a deciduous forest? Except for having trees that are all approximately of the same height, hardly any other plants grow in a deciduous forest, except for young plants of the same type of trees. This experiment shows how the light intensity in a mixed forest of oaks and beeches changes in the spring during the foliation of the trees. It also demonstrates the effects on the vegetation.
