The September issue of ESTUARY News magazine explores transitions in wetland protections, describes new computer models designed to track how nutrients move around the Estuary, and takes readers into a college class engaged in sorting mucky bottom sediments for benthic creatures such as invasive overbite clams. The issue also reviews a new neighborhood creek restoration book, a new Delta report on vegetation on levees, and how birds have responded to salt pond restorations. Finally, responding to reader requests, the issue also delves into seven magazine stories from 2012 to 2016 to see what’s happened since.
