Why is plant diversity important?
If your lawn is primarily a monoculture of Kentucky bluegrass, it may be effective in maintaining a manicured look, but it will not sustain a diversity of animal species. Similarly, a wetland dominated by purple loosestrife cannot sustain a diversity of native wetland plants or animals.
A woodland dominated by garlic mustard and bush honeysuckle will not enable a variety of wildflowers to grow.
