The Scary New Math of Warming

Posted in Library, News & Publications on 02/8/12

Toronto Star, The Scary New Math of Warming; published 21 November 2009 by Peter Gorrie A recent environmental summit set ambitious new targets for reducing greenhouse gasses. If new environmental campaigns take hold, you'll hear a lot about two numbers during the next few months. If they succeed, you could find yourself living, and thinking, differently. The numbers are 350 and 50. The first is a target for reducing the...

Conservation Beyond Crisis Management

Posted in Library, News & Publications on 02/8/12

Conservation Beyond Crisis Management: A Conservation-Matrix Model A Discussion Paper for the Canadian BEACONs Project In many regions of the world, failure to plan effectively for conservation of biological diversity has led to irretrievable losses of ecosystem structure and function or, at least, a need for expensive and risky restoration efforts. In relatively intact systems, planning pro-actively for biological conservation requires a systems approach that integrates the fields of conservation...

Conservation Targets: Do They Help?

Posted in Library, News & Publications on 02/8/12

Conservation Targets: Do They Help? By Michael E. Soulé & M. A. Sanjayan; Science, New Series, Vol. 279, No. 5359. (Mar. 27, 1998), pp. 2060-2061. The most irreversible environmental problem of this era is the projected rapid loss of biodiversity, including the disappearance of up to half the world's species. In response, many international commissions and nature conservation organizations have called for the near-term protection of at least 10 or...

How Much is Enough?

Posted in Library, News & Publications on 02/8/12

Center for Large Landscape Conservation; Literature Review on Select Topics in Landscape Conservation; May 27, 2010 How much is enough? What is the minimum area required to ensure the maintenance of biodiversity in an area? A 10 percent (or 12%) conservation target of land area in each nation (Myers 1979, Miller 1984, Soule and Sanjayan 1998) is frequently cited and has been recurrently used in setting policy, though with little...

The A-Z of Areas of Biodiversity Importance

Posted in Blog, Library, News & Publications on 07/7/11

The terminology of conservation can be confusing.  Endless acronyms and very specific terms that only the 'specialists' can decode.  For Nature Needs Half, we use the protected area categories as defined by the International Union for the Conservation of Nature (IUCN).  The IUCN categories define protected areas according to the management objectives, but don't always mesh with in-country or local definitions and terminology. There are many other terms to define important biodiversity...

Why “interconnected” is important

Posted in Blog, Library, News & Publications on 06/2/11

Sarah Kuck recently wrote a great article for YES! Magazine about why wildlife needs room to roam and why connecting protected areas is important.  She highlights issues such as global climate shifts, loss of natural predators and the need for conservation to include economic opportunities for local communities.  Her dialog very clearly and concisely summarizes the need for large, protected areas that are interconnected - in essence, why Nature Needs...

Nature News: Marine protection goes large

Posted in Library, News & Publications on 05/31/11

As the creation of giant reserves gains momentum, some fear such areas don't always conserve the habitats most in need. The past five years has seen a spurt in the creation of giant marine protection areas, including a 320,000 sq km marine reserve announced earlier this month in Australia. "Now we have a competition for politicians to see who can have the biggest one," said Daniel Pauly of the University...

Boreal blues - In the frigid north tension grows between conservation and development CANADA’S vast boreal zone contains the world’s largest intact old-growth forest and has more fresh water than the Amazon. Its flora help to slow climate change and it is a breeding ground for 3 billion migratory songbirds. Only 12% of the region is now formally protected, well below the 50% scientists say is necessary to save its...
