Through modern industrial logging practices, old growth forests are clear cut logged and that complex diversity of trees is destroyed.
Whether replanted or regenerated naturally, secondgrowth forests have a reduced diversity of trees. Replanted trees are often from limited seed stock that reduce the genetic variation of the forest, and these trees are more susceptible to disease or insects who may be interested in certain species at certain ages. This is exacerbated by their tight spacing that reduces moisture and increases competition for nutrients and light, which increases their stress and makes them more susceptible to those pathogens. This tight spacing, low moisture, and lack of diverse, fire-resistant older trees, makes the entire stand more prone to drought and wildfire.
Through ecological restoration of these secondgrowth forests to increase spacing, diversity, and ages, we can help create a dynamic and diverse forest. Though it is no substitute for preserving intact complex forests in the first place, restoration of these unhealthy secondgrowth forests created through industrial logging can help increase their complexity and diversity in the short term and develop more ecologically functional forest ecosystems that are more resilient to the impacts of anthropogenic climate change.
