Red worms or manure worms can grow to about 5-7 centimetres (3 inches) long and will eat their own weight in garbage every 24 hours. When worms are used in composting it is called vermicomposting.
Learning About Reforestation from Mount Saint Helens
Large-scale ecological disturbance and forest regrowth.
The 1980 eruption of Mount St. Helens devastated ancient forests in the Cascade Mountains of southern Washington State. Global Forest is supporting scientists from the University of Victoria, BC, and Oregon State University, USA, in an ongoing 20- year study to examine research sites originally covered in volcanic ash. This work is providing a first hand account of how forest ecosystems recover and naturally reforest after a large-scale volcanic disturbance.
