First ask yourself if your yard looks like the left half of this photo or the right half.
If you said 'left' I can't offer any advice. If you said 'right' that's a good answer.
Fourteen years ago this lot was just bare sand, fallen leaves, and empty beer cans...and a few rusted car parts. In one area of my yard I created what I call my "Mini Woodland Garden" which contains a variety of plants that provide cover, pollen, nectar, seeds, etc. for a variety of creatures. American Beautyberry, Bottlebrush, Society Garlic, Evergreen Wisteria, Red Trumpet Vine, Rose of Sharon, Canna, Veronica, Rosemary, Lilyturf, wild Blackberry brambles (I don't plant them)...that's all I can remember off the top of my head, but there are lots more plants in that area.
Just last year I discovered how to protect Anole eggs (with some help and encouragement from
@Gleni half way around the world, thanks!) and the baby lizards taught me the importance of heavy cover with something to attract a meal small enough for a little lizard's mouth. The baby lizards thrived while protected by the Sweet Autumn Clematis and they had lots of critters to keep them company.
At the back of the yard I keep a buffer near the fence; about 3 - 4 feet of wild vegetation. I only cut back what gets out of hand. There are always stacks of empty pots and some stacks of lumber and those make a nice home for some.
The only other thing is to provide water; shallow pans/containers of rainwater, some with pebbles so the honeybees don't drown.
I want to add one more photo but will do that later. The dinner bell just rang!
