The first 2 miles of the Main Trail are now open, which means you can have a 4-mile hike, which is definitely long enough to make the trip worthwhile. Buescher offers a much lusher, greener experience than most Austin-area hikes, winding through the Lost Pines and following a small creek. There were lots of lichens, mushrooms, true moss, and Spanish moss, as well as a number of grasses, cedars, and lots of yaupon. And, of course, loblollies. We didn't notice any fire damage, but we weren't really looking for it, either, and we were there late in the day and didn't explore the park beyond the one trail that's open.
The stretch we walked didn't have a lot of elevation changes (which was fine with us) and no dramatic overlooks, but was a pleasant, intimate walk with only a few other folks on the trail.
