Our August Chapter Meeting speaker was our old friend, Tim Siegmund, from Texas Parks and Wildlife. He spoke on “Prairies, Woodlands, Wildlife, and Managing for Diversity.” He had many wonderful photos that showed how careful management of land can result in habitat for a wide variety of life.
First, he told us what shaped the land before we Europeans showed up and turned our post oak savanna into more of a thicket. For the most part it was maintained by the large grazers (bison, mammoths, prairie dogs, and such) and fires. Some of the fires were natural, but many were also set by Native Americans for many reasons, plus natural ones. Drought also affects the trees, especially wetland species.
In all, the land was lightly used, since the heavy grazers migrated, creating a variety of settings for different birds, insects, and plants depending on how recently they’d been through an area.
He then explained how settlers intensified the use of land. An important factor was that they built fences, so grazing became year round and focused. The cattle/sheep, goats and friends would repeatedly graze the same area, giving no time for deep-rooted perennial grasses to recover. Soon enough, plants like cedars, huisache, and mesquite would fill in the grasslands.Continue reading “August Chapter Meeting: Tim Siegmund”
