Now let's review the four steps needed to regenerate oaks. First, measure potential sources of oak regeneration. These may include seedlings, stump sprouts, or acorns. Second, control competition from undesirable trees, shrubs, and herbaceous plants. Third, apply a regeneration and harvest system that encourages oak regeneration. These include group selection, clearcutting, or shelterwood. And fourth, control competition and monitor oak development after the harvest.
