During the value engineering process, a lot of the plantings were removed for budgetary reasons. I need to re-introduce them but judiciously to get back to the spirit of the credit. When is a lawn considered non-monoculture?

A maple tree? overseeding with another grass species? A group of native bushes in the corner? I want to achieve bio-diversity and get closer to a habitat than the lawn can afford, but I can't rip it out and replace it.

How do I get there?
