Quick Facts

Audio Description

Near the post marked 5 and actually many locations along the trail, you can see various decomposing logs and fallen trees. Bacteria, lichen, fungus, moss, and seedlings take advantage of the nutrients, moisture, and sunlight made available to them by these fallen trees. Large trunks and limbs of which are often referred to as nurse logs. Why do you think that is?

These rotting logs are an important part of the life cycle of the forest. Their decomposition frees nutrients, which would otherwise not be available.

Bacteria and insects are among the first organisms to make use of the dead wood. They break it down for use by other life forms. Fungi and mosses also break down dead wood and use its nutrients. As decomposition advances, more complex plants such as flowers and tree seedlings get their nutrients, moisture, and shelter from the rotten wood. Advanced decomposition also adds nutrients and organic matter to the soil, which benefits other organisms.
