In this activity, students investigate the range of conditions that animal and plant species need to survive in an estuary. They examine data for abiotic factors that affect life in estuaries - salinity, dissolved oxygen, temperature, and pH. Students use archived data (trend analysis graphs) and real-time conditions at Elkhorn Slough to predict whether a particular animal or plant species could survive in an estuary.
