  • 3. Soon the floor of the forest is covered with multi-colored leaves, red, yellow, and orange.

  • 5. Pine trees shed their needles onto the forest floor.
  • 6. Leaves, needles and twigs form a new ground cover for the forest each fall.
  • 7. Pine needles fall and lay among the ferns
  • 8. adding yet another layer to the forest floor.

  • 11. Twigs, curled dried leaves, and scat, all forest litter, contribute to the forest floor.
  • 12. “As fall progresses, sunny days give way to long slow drizzles.” Bernd Heinrich. The Trees in My Forest
  • 13. Mushroom-forming fungus has long thin filaments, or hyphae, that can reach underground in all directions. Bernd, Heinrich, The Trees in My Forest.
  • 14. The ground and deadwood are riddled with networks of fungal hyphae." Bernd Heinrich. The Trees in My Forest
