Wetland Restoration Outcomes

Evaluating outcomes of hydrological restoration in grazed and ungrazed seasonal wetlands

We assessed restoration outcomes in 15 depressional wetlands on a seepage slope on the southern Lake Wales Ridge. Ten study wetlands were hydrologically restored under USDA’s Wetlands Reserve Program. Cattle were fenced out of five restored wetlands, resulting in three treatments: restored-ungrazed, restored-grazed and unrestored-grazed. Pre- and post-restoration monitoring of plant communities allowed us to assess effects of increased water levels and continued grazing.

Major Findings & Impact

Plugging off ditches effectively increased wetland depths in the restored wetlands. Maidencane, a native grass, increased significantly in ungrazed wetlands. Overall, the vegetation responses to restoration were slow and subtle, with desired changes in plant communities only becoming detectable 5 years following restoration. Our results emphasize the need for long-term monitoring to assess success of costly restoration activities.
