Trees are living organisms just like us who need nutrients, air, water and sunlight to survive.

  • Trees are the largest plants on the planet, and they are perennial (which means they live more than 2 years).
  • They have limbs, trunks and roots. Think of the limbs like our arms, the trunks like our bodies and the roots as our feet.

Some of the benefits that trees provide are:

  • They reduce erosion, storm-water runoff, moderate the climate, water cycle and stabilize the soil.
  • They remove carbon dioxide from the atmosphere through storing large quantities of carbon in their tissues.
  • They improve air quality
  • Provide a habitat for many species of animals and plants.
  • Provide food through their leaves and fruit for many species of animals.
  • Trees even provide shade and shelter for animals and humans as well and have many more helpful attributes.

Without trees, the towpath along the canal could crumble and erode making it unsafe to travel. The stabilization of the soil that trees provide is a great service for the C&O Canal.
