What is “ecological restoration”?

People and nature - Working together This Harms Woods Lacking fire, this oak woodland became choked with buckthorn.

With buckthorn gone, an oak woodland is revealed. Now there’s room for normal plants to return.

Three years later, the woodland is thriving. With increased sunlight and seeding of native plants, this area is recovering.

What do volunteers do? Remove invasives (bad plants) to create room for native plants. Pulling garlic mustard Cutting down buckthorn
