What is the expected tree density in a climax community after approximately 150 years?

• A. 3,000 trees per unit area
• B. 5,000 trees per unit area
• C. 15,000 trees per unit area
• D. 20,000 trees per unit area

Answer: (C)

In a climax community, which represents a stable and mature ecological stage, the tree density typically reaches a balance determined by factors such as species competition, resource availability, and environmental conditions. After approximately 150 years, ecosystems often establish a diverse and complex structure where the interdependence among species contributes to an optimal number of trees per unit area. In many temperate forest communities, tree densities can range significantly but often fall within the range of several thousand trees. A density of 15,000 trees per unit area aligns well with the notion of mature forests where competition among trees has led to a sustainable ecosystem structure. This number suggests a balance where enough trees are present to utilize available resources without overwhelming the environment, which is characteristic of a climax community. This stage allows for older trees to support a diverse understory, promoting biodiversity while maintaining density levels that do not cause excessive competition, leading to disease or tree mortality. As a result, this reflects an equilibrium that typifies the ecological characteristics of a climax community at this age.
