What kinds of animals live in old-growth forests? Although eastern US forests lack old-growth dependent species, many kinds of wildlife do prefer deep, interior woods with more old-growth traits such as large trees with cavities.
Perhaps the best known visual signs of old-growth forests are their truly enormous trees. You can accelerate large tree growth in your woods by finding your healthiest “legacy trees” and removing competing trees around them so the big trees can grow faster.
If your woods are short on snags (standing dead trees), you can create some of this valuable wildlife habitat by girdling trees. Girdling kills a tree while leaving it standing so it can become a snag.
True old-growth forests have greenery at every level from the forest floor to the top of the canopy. You can start some new growth on the ground using small patch cuts, which remove every tree from an area less than an acre.
