This newsletter is the second annual Patuxent River ecosystem health report card. The report card provides grades for the three tidal regions of the Patuxent River estuary. The grades are based on the frequency that the river is able to meet six ecological targets. The results show the river is generally in poor condition despite a small improvement in the health in 2008 (compared to 2007).

This newsletter introduces the first Patuxent River ecosystem health report card.

The report card grades are based on the progress of six indicators towards ecological targets. The report card shows that the Patuxent River estuary is mostly in poor condition and that substantially more effort is needed to see measurable improvements.

An assessment of nitrogen sources to the Choptank and Patuxent River (including Island Creek), was conducted during the summer of 2003. Results demonstrated that both rivers were compromised with sewage derived nutrients. An Ecosystem Health Index for defined reporting regions was calculated from a variety of ecosystem heath parameters and then converted to a report card grade from A+ to D- and F for fail (Table 1).
