The document discusses biodiversity, including its definition and benefits. It notes that biodiversity includes genetic, species, and ecosystem diversity. Biodiversity provides ecosystem functions and services like clean air and water. It also discusses threats to biodiversity like habitat loss and overharvesting. The document recommends protecting biodiversity through establishing protected areas, implementing sustainable practices, and enacting laws like the Endangered Species Act.
(See notes below) Four hundred years ago, the Chesapeake Bay that the English colonists found here was lined with huge oyster reefs that grew up from the bottom in waters both deep and shallow. Those reefs provided the base for much of the life in the Bay and its rivers, from worms and barnacles through mud crabs and tiny fish to big blue crabs and predators like sheepshead, drum, and rockfish (striped bass).
The oyster reefs weren’t as “pretty” (to us humans) as the coral reefs further south, but in terms of ecosystem richness, they were just as important. One key to their strength was their three-dimensional structure, which successive generations built gradually on the shells of their predecessors over several thousands of years. The structures placed the oysters up in the water column, away from gill-choking bottom sediments, where dissolved oxygen was plentiful and currents brought food in the form of algae cells seeking sunlight.
This PowerPoint presentation, developed by the Chesapeake Bay Foundation’s Fisheries Program Director Bill Goldsborough, tells the story of those reefs and what has happened to them over the past four hundred years. It is not a pretty story, but it offers a hopeful conclusion, as we learn more each year about how to restore these essential elements in the Chesapeake ecosystem.
Anglers have as much to gain as anyone in restoring the Chesapeake’s oysters. The presentation closes with suggestions for how to get involved in oyster restoration, and how to incorporate the restoration reefs into your 2015 angling season.
