It was billed as a “hike” that might take 2.5 hours, but David Hurt, the grand benefactor of Dogwood Canyon Audubon Center, was the guide — at the two hour mark we had just ambled to the blossoming trees in their still-semi-secret location. Amble, not a hike.
Great day to be outside.
David Hurt spent 14 years working to establish the reserve and education center at Dogwood Canyon, in Cedar Hill, Texas — now he just can’t resist leading tours of the better sites and sights.
The voyage is at least half the fun.
After more than a year of serious drought, some of North Texas experienced high rainfall in the past three months. Spring-fed streams and seeps on Cedar Hill and across the Escarpment flow well for the moment, lending hope to wild bird breeding. On some entangled bank . . .
Mr. Hurt often stopped to explain bird songs and habits, and despite his claim not to like “plant people,” he stopped most often to identify plants, or to compare plants that can be confused. This Audubon facility sits in a transitional zone, between two kinds of prairies. It’s forest nature is an oddity in the zone. Dogwood Canyon features plants more commonly identified with the Texas Hill Country and with East Texas, as well as Blackland Prairie plants considered icons of the area. In this case, Hurt showed the differences between Texas redbud and eastern redbud, both of which occur in this area. Hurt carefully demonstrated how to identify poison ivy, now in abundance off the trails. This was a sharp contrast to two weeks ago when I couldn’t find a single sprig of poison ivy to show Scout leaders.
Poison ivy along the trail. Keep away.
Is it eastern red oak, or something else? How to tell?
Hurt showed how to make a nest from loose bark strips from Ashe juniper trees. Golden-cheeked warblers, a threatened species, require this bark for nesting, and it can come only from mature Ashe junipers. The birds need this nesting material close to a good stand of deciduous trees, where they catch their food.
The dogwoods in bloom! An early spring, and lots of water, pushed the trees to leaf out before blossoming started — usually the blossoms come first. The drought last year probably hurts blossoming this year. Blossoms are not yet at their peak.
Exquisite aroma and beauty from the dogwood blossoms – not the carpet of white we saw in a previous year. Still just the shock of finding these little beauties in Dallas County adds to their splendor. Dogwoods do well in East Texas, where it is wetter and the soil is acid. Here on the escarpment it is generally dry, hotter, and the soil is thin and alkaline. That the blossoms show up at all is a stunning oddity, a stroke of fortune emblematic of the unique place that is Dogwood Canyon.

My blog, Millard Fillmore's Bathtub, is a continuing experiment to test how to use blogs to improve and speed up learning processes for students, perhaps by making some of the courses actually interesting. It is a blog for teachers, to see if we can use blogs. It is for people interested in social studies and social studies education, to see if we can learn to get it right. It's a blog for science fans, to promote good science and good science policy. It's a blog for people interested in good government and how to achieve it.
