Saving endangered species in gardens

The Wildlife Management Plan is a fairly formal plan made out specifically for the appraisal district to review, so it has to contain certain things.  We have to perform a minimum of three practices from a list of practices, but we always do more just to be safe.  The management practices we use are Habitat Control (brush cutting, planting native seeds), Erosion Control (rock dams, brush dams, basins, berms), Provide Supplemental Supplies of Water (tubs, basins, pans, small garden ponds), Provide Supplemental Supplies of Food (bird feeders), and Provide Shelters (brush piles).

I've been planting native seed mixes from Native American Seed   http://www.seedsource.com/    

I have to fence each patch because we have so many deer.  I've also been putting up fencing simply to exclude deer from some areas so native trees and shrubs can grow back on their own.

Thank you for the very clear explanation.  I looking at the seedsource list for Hummers & Singer Mix and it looks like the Purple Coneflower and the Black-eyed Susan that I am planning to plant are on the list and these are deer resistant, too.  Gayfeather and Scarlet Sage is on both lists, too.  I'll research the songbirds I have and see what they like best.

We planted raspberries in several places soon after we moved here. Wrens tried nesting in one clump, but the cats destroyed the nest. They moved to another clump where the cats can't get to the nest. This area is now their home. Lots of bugs are there not only because of the fallen fruit, but also because the mice like to eat it and they poop. The soil is fertile because of all the activity. All we provide is a pan of water. Same for the critters on the other side of the trailer. I hate to thin the plants and possibly ruin their home, but if I leave it alone, the plants will get diseased and die. Everyone loses.
