The Skimmer on Marine Ecosystems and Management

Editor's note: The link between watershed management and marine EBM is no better exemplified than in the case of Chesapeake Bay, on the east coast of the US. Significant efforts to improve the health of the Chesapeake over several decades have focused largely on reducing upstream pollution. So far, however, those efforts have been unsuccessful in returning the bay to good health (see box at the end of the following essay).

Many areas of the ocean are off-limits to human activity for reasons other than conservation. Zones around coastal military bases may be completely closed for security purposes. Waters around oil platforms often restrict fishing or access in general. Anchoring is forbidden around undersea cables. These restrictions, by the fact that they limit some human impacts on these ocean sites, provide a degree of protection for the ecosystems there. For this reason, they are sometimes referred to as "de facto marine protected areas" - meaning MPAs in practice but not in law.

Last month's MPA News described how endowments can help provide sustainable financing for MPAs. To establish such endowments requires money. The Nature Conservancy and other international NGOs and institutions have helped finance several MPA-related endowments in recent years. Below, Bill Raynor and Trina Leberer of The Nature Conservancy's Micronesia Program offer advice for MPA practitioners on how to approach potential donors for endowments:

There are multiple sources of financing for MPAs, including domestic government budgets, international assistance, visitor fees, and more. While each source plays a vital role for sites worldwide, it can also be subject to fluctuation. Domestic budgets can be cut. International donors can change their area of interest. Tourism rates can rise and fall. These variations create instability for MPA management.
