What does biodiversity loss refer to in forestry?

Biodiversity loss in forestry specifically refers to the reduction of species variety and abundance within forest ecosystems. This phenomenon can manifest in the decline of native plant, animal, and microorganism populations, leading to less genetic diversity and fewer interactions among different species. Healthy forests typically contain a wide range of species, each playing unique roles that contribute to ecosystem stability, resilience, and functionality. A decrease in this diversity can result in ecosystems that are more susceptible to diseases, pests, and environmental changes, ultimately compromising their ability to thrive and support wildlife and humans alike.

While increases in invasive species and loss of forest cover can contribute to biodiversity loss, they are parts of larger dynamics rather than the essential definition of biodiversity loss itself. Growth of tree biomass, on the other hand, does not inherently relate to the concept of biodiversity and can occur even in systems that are suffering from a decline in species variety and abundance. Therefore, understanding biodiversity loss encompasses a broader perspective aimed at preserving the complexity and health of forest ecosystems.
