Plant Succession (1963)

The film discusses plant succession, the process by which one type of plant life replaces another over time. It explains how environmental factors such as soil, sunlight, precipitation, and temperature influence which plants can grow in an area. The process begins with lichens that thrive on bare rock, contributing to soil formation. This is followed by mosses, grasses, shrubs, and eventually trees, leading to a climax community such as a deciduous forest. The film also touches on how human activities can alter natural plant succession, leading to changes in the types of vegetation that thrive in a given area.
