Sometimes woodlands can benefit from interplanting – the introduction or addition of desired plants, either alone or in conjunction with selective thinning, timber management, or prescribed burning. Seedling trees, shrubs, or woodland wildflowers and forbs can be interplanted.

A woodland that has been grazed or originated from an abandoned crop field or pasture may contain numerous plant species that do not provide optimal wildlife cover or food. It may also lack the important wildflower component or contain mostly disturbance tolerant species like poison ivy or exotic, invasive species like garlic mustard and Japanese honeysuckle. A site like this will need to be "opened up" by removal of undesirable trees, shrubs, and herbaceous plants. You can eliminate unwanted vegetation with the methods described earlier. If you are leaving trees in your planting area, be sure not to plant new trees close to the existing ones. Shading and nearby root competition both can hinder the growth of the newly planted trees. Once there is physical spa e to intr9duce the new plants, determine what is needed to improve the plant-species diversity of the site. Be sure to use only native species appropriate to the site.
