Oldgrowth vs Secondgrowth Forests: Canopy Gaps

In ancient forest ecosystems, things are constantly growing and dying, so as trees fall over or branches come down in various disturbance events, gaps in the canopy open up to allow light to reach all layers within the forest. This creates an incredibly rich and diverse vegetation layers from the forest floor to the understory up to the canopy, and while we tend to think of forests just for their trees, it’s often this rich vegetation that performs many of the ecological functions we depend on to survive as well as storing a large portion of the carbon in these ecosystems.
In a common second growth forest, the tightly packed monoculture of trees often form a tight canopy and without species and age diversity, there are very few significant disturbance events to create any gaps in this canopy. This lack of light reaching the forest floor means that the understory isn’t able to develop in the same way, which inhibits a forest ecosystems ability to perform ecological functions such as absorbing water and reducing erosion, as well as storing carbon to help mitigate climate change.
With forest industry reform, we can modify our management practices with extremely selective harvesting that introduces Oldgrowth characteristics back into these forests to increase biodiversity and resilience while creating sustainable jobs and industry in our communities.

based on feedback from the longer video I did about Oldgrowth & Second growth forests (in which the two sites I used were less than 2ks apart), this whole series was shot in the same microclimate on sites within 250 meters of each other.
