September 19: 10 Centuries of Dynamic Change

Jim Frisinger will present Comings and Goings at the Southwest Nature Preserve – 10 Centuries of Dynamic Change to 58 acres in the Cross Timbers.  Jim will walk us through a little neighborhood history: Waves of human migration. Cycles of drought and rains. Invasions of new plants, and disappearances of others. Gone are the bison – but there is more water and woody plants here than ever. Ecosystems are dynamic, buffeted by outside forces and ever-changing. Now the 58 acres heads back to the future as a wildlife preserve.
Jim Frisinger, who organizes the birding classes for the Friends, left a decades-long career as a daily newspaper journalist in Dallas-Fort Worth to join the U.S. Army Corps of Engineers Fort Worth District. He now writes and films stories about the Corps work on endangered species, ecosystem restoration, flood-risk management, sustainability and national security construction.
