Launch of new “MPA List” email discussion list

Dear reader, I am very pleased to announce the launch of a new email-based discussion list for the marine protected area community: the MPA List. Created by MPA News, the MPA List provides a simple way for managers, researchers, and others to share knowledge, discuss...

Global study finds conservation success increases dramatically when MPAs have five key features

A study of 87 marine protected areas worldwide has found that conservation success – as indicated by fish biomass – improves exponentially when an MPA has five key features.  Those recurring characteristics are:

  • No fishing allowed;
  • Well-enforced;
  • More than 10 years old;
  • Relatively large in area (larger than 100 km2); and
  • Isolated from fished areas by habitat boundaries, such as deep water or sand.

The emerging concept of marine biodiversity offsets and their potential uses with MPAs

Several presentations at IMPAC3 addressed a relatively new concept in the ocean management realm: marine biodiversity offsets.  A biodiversity offset is a way to demonstrate that an infrastructure project is implemented in a manner that results in "no net loss" of biodiversity.  If the installation of a proposed offshore oil drilling platform, for example, is anticipated to have certain negative impacts on benthic habitat, an offset could involve protecting similar habitat elsewhere, or fostering new habitat, to balance the habitat loss at the platform site.  (If a project has already been implemented, an offset could involve restoring any habitat that has been degraded in the process.)

Such offsets, sometimes referred to as compensation, have existed in land management for a while.  But the idea has only become more common in ocean management as industries such as petroleum exploration, renewable energy, and seabed mining establish a greater marine presence.
