Impervious cover increase, Lowndes County

Sixty eight percent (68%) from 1991 to 2005, 22% of that from 2001 to 2005. Tree canopy change from 1991 to 2005: minus fourteen percent (-14%), almost all of it between 2001 and 2005.

Where’s all this change coming from and going to?

The dark green is labeled “Evergreen Forest” and decreased from 31.81% in 1991 to 26.47% in 2005. Meanwhile, the light pink labeled “Low Intensity Urban” went from 5.37% to 8.57%. Other changes include the red “High Intensity Urban” slice going from 1.15% to 1.98%. But the biggest change is piney woods being paved over for urban sprawl.

Could this have some effect on flooding?
