True. The concept of ecological restoration is also a moving target. It neither makes sense nor is possible to restore it to how it was before because many of those species of flora and fauna do not exist natively in the region any more, or could survive and contribute productively to the biodiversity of the target ecosystem. You just kind of make a plan, shoot for it, and adjust as it evolves. The Magpie Forest is neat and very accessible but there are certainly a lot of non-native species there now, which is fine. The other ones you mention: Rose Creek Preserve, and the privately accessible one south of town are better examples of what they would aim towards out at Steptoe. I worked at the one south of town and there's nothing immediately spectacular about it that would grab the attention of people who aren't patient, or don't appreciate such things—it's very much a prairie-density sort of land, no water like at Rose, and more of an island within the surrounding agriculture, but every now and then things get very quiet and you look around and you start seeing different species of birds and hawks soaring in the skies above, or you notice the giant but gentle bumble bees all around you in large numbers. Things that are just sort of unobtrusively co-existing, contributing and dependent on that environment.
