Audubon's work with partners to restore the health of the Guana River System in the Northeast Florida Ponte Vedra Beach area has reached an important milestone. After years of effort on a water quality data project championed by staff at the Guana Tolomato Matanzas National Estuarine Research Reserve (GTM Research Reserve) and supported by the local community, enough data has been collected to show nutrient impairment in the Guana River and its headwaters in Ponte Vedra Beach. While this finding is unfortunate, recognition of impairment according to state water quality standards makes clear the troubles facing this beautiful resource in Northeast Florida, and will set the stage for serious efforts to restore water quality in the region.
