Rotting Logs
Wonder Spot: Explore the Arboretum through seasonal investigations
Have you ever wondered what happens to a tree or branch after it falls over?
Find a fallen log or stump in these woods. Examine the areas on, around, and under the log. Note all the living things you see. Also notice the temperature and moisture of the study area.
Use your nature journal to record the animals, plants and evidence you observe, using drawing and labels.
Investigate the following:
- Look for holes, animal scat (droppings), chewing marks and other evidence that show how animals use the log.
- Look for moss, lichen, and other plants that may be growing on or near the log.
- Examine the leaf litter around the log. Look for evidence that invertebrates (animals without backbones) have been breaking down the leaves or using them as shelter.
- Touch the log. Does it feel moist or dry? Does it crumble easily?
- Can you find mushrooms growing on or around the log?
- What does the log smell like? What does the soil and leaf litter smell like?
