The Bay Program has released its Chesapeake Bay 2007 Health and Restoration Assessment, a four-part snapshot of health conditions and restoration efforts in the Bay and its watershed. The assessment indicates that the overall health of the Bay remained degraded in 2007. Despite the extensive actions of Bay partners to combat factors slowing restoration progress, the Bay Program is still far short of most restoration goals.
Of the key indicators of Bay health, the assessment shows that:
The reasons for the continued poor health of the Bay are described in Chapter Two: Factors Impacting Bay and Watershed Health. The Chesapeake is affected by multiple factors -- ranging from population growth to agricultural runoff to climate variability -- that challenge the ecosystem's recovery.
If current development trends continue:
Chapter Three: Restoration Efforts highlights Bay Program partners' progress toward reducing pollution, restoring habitats, managing fisheries, protecting watersheds and fostering stewardship.
Bay Program partners continued to make progress toward goals to open fish passage, restore forest buffers and preserve land in 2007.
At the December 2007 Chesapeake Executive Council meeting, each Bay jurisdiction chose to “champion” issues vital to restore their streams, rivers and Bay waters. “Champion” issues include enhancing agricultural conservation practices, engaging local governments in upstream communities and “greening” urban areas through improved stormwater controls. The outcomes of these projects and programs are intended to be models for restoration that can be used in other areas of the watershed.
New to the assessment this year is a chapter on the health of the Bay watershed's extensive network of freshwater streams and rivers. The presence and diversity of snails, mussels, insects and other freshwater benthic macroinvertebrate communities are good indicators of stream health because of their limited mobility and known responses to environmental stressors. As a result, these communities are often used as indicators of the general health of freshwater streams and rivers.
Separately, the University of Maryland Center for Environmental Science(UMCES) has released its 2007 Chesapeake Bay Health Report Card, a geographically based assessment of the health of the Bay examining conditions in 2007. The UMCES Report Card shows that 2007 ecological conditions in the Bay were slightly better than the previous year, but far below what is needed for a healthy Bay.
