The day after Thanksgiving, November 24, the itch to get outside combined with perfect weather – I had to go somewhere. I headed for the Fort Worth Nature Center and Refuge, a place that, after practically a lifetime of walking its trails, feels like home. I have a dim recollection of going to Greer Island with Rick Pratt, from whom I learned a lot at the museum as a young volunteer, soon after the first 380 acres had been set aside as the “Greer Island Refuge & Nature Center.” That was in the mid-1960’s. A lot has changed in the fifty years that followed; the refuge expanded to become the largest city-owned nature center in the country, and the twenty miles of hiking trails leads you through cross timbers woods, prairie, bottomland forest, marshland, and limestone caprock at the top of a ridge. It feels familiar and welcoming, like an old friend who you see from time to time and immediately resume a comfortable and warm relationship. It is like home.
In yesterday’s homecoming, my aim was to visit some places along the oak motte trail. One of them is a patch of prairie within the oak woodland, where a giant live oak tree overlooks a gentle hillside with prairie grasses and yucca. Here is some of what I wrote in my notes, at 1:30pm:
I’m sitting beside a very big live oak tree with the early afternoon sun at my back, looking out across a little prairie within the Western Cross Timbers. Here, the soil is a sort of ash-gray, but as the elevation drops, more caliche and limestone appears, with more yucca and the grass is more sparse. Below that, a rusty beige line shows where little bluestem is dominant.
As I walk down to the line of bluestem, it is obvious that (a) a tremendous diversity of grasses and forbs is present, and (b) my plant identification skills are not nearly up to the task. There appears to be broomweed growing amid the yucca, and who knows how many other species, from small, ground-hugging plants to a few big clumps of Indiangrass growing more than head-high. The prairie is dotted with a mesquite here, a couple of junipers there.
An American snout butterfly comes in over me, low and hard, fluttering away in a strong tailwind. These butterflies are out in force today, and for the most part they make it hard to photograph because they take off when approached. They must have some orange or yellow on the dorsal wings, but their flight is constant motion and when they rest on a stem of grass, their wings are folded, showing shades of gray with a little orange showing where one wing disappears beneath another.
So far I have seen a northern cardinal, a mockingbird, a few turkey vultures soaring overhead, and only a couple of other small unidentified birds. The woods and fields are mostly quiet.
As the afternoon progresses, the sun is getting low and the quality of the light makes everything look more beautiful. Autumn here is an amazing mix of yellow, tan, rust, brown, orange, and red, with splashes of green. The yellows and russets of the grasses paint pictures with so many textures and patterns. It is 78 degrees (F) and 22% relative humidity. There is a light breeze. I want to stay!
