IUCN ‘Guidelines for Conserving Connectivity through Ecological Networks and Corridors’
By Rachel Caldwell
Conservation Program Officer, Center for Large Landscape Conservation
CCSG will soon release the first-ever IUCN Guidelines for Conserving Connectivity through Ecological Networks and Corridors. The main objective of these Guidelines is to clarify and standardize consistent practices for the effective design, governance, and management of larger conservation networks of protected and conserved areas that are connected by designated ecological corridors.
What Is “Ecological Connectivity”?
As defined by the UN Convention on Migratory Species in February 2020, “ecological connectivity is the unimpeded movement of species and the flow of natural processes that sustain life on Earth”. This definition demonstrates the importance of connectivity conservation solutions, and everything they protect, including invaluable resources like water and nutrient cycling, pollination, seed dispersal, food security, and disease resistance.
About the Guidelines
The Guidelines are the culmination of over two decades of effort by the IUCN, and the result of contributions from more than 100 experts in 30 countries. When complete, they will provide managers, policymakers, and experts across the globe with insights into the science, definitions, and principles for planning and managing for ecological connectivity, as well as 25 case studies illustrating projects around the world.
Why It Matters
Connected ecosystems are more resilient. They support plants, animals, and biological processes and permit them to persist in an increasingly human-dominated world. However, more than half of the planet is now developed and this is threatening human well-being, accelerating species loss, and limiting nature’s ability to withstand the impacts of climate change. Safeguarding ecological connectivity is a proven conservation measure, and the Guidelines bring together the most current knowledge and proven practices to lead a new global effort to combat habitat fragmentation and protect intact ecological networks for conservation.
National parks are in dark green and protected areas are in light green. The Kavango-Zambesi area includes sections of Angola, Zambia, Zimbabwe, Botswana and Namibia and is also home to approximately 2 million people!
Sound ecological management requires careful planning aimed at ensuring corridors for wildlife moving throughout these multi-jurisdictional landscapes. Using the guidelines, complex areas like this can access and apply globally-agreed-upon standards and best practices for promoting connectivity within protected areas, increasing ecological health across the world.
