BOTANY ALBERTA is planning their annual get-together for the weekend before BOTANY BC: August 3-5 in Lake Louise, AB. For costs and more information about this event check the Alberta Native Plant Council website http://www.anpc.ab.ca/ or contact Mari Decker at email@example.com . Accommodations for the Alberta meeting will be at the beautiful and reasonably priced Lake Louise Hostel and the Lake Louise campground for those who prefer to tent. Bonus Botanizing: There is also an opportunity to extend your trip by attending BOTANY BC 2013 and enjoying two botany weekends in a row!
This year Botany BC will be held in the spectacular Columbia Mountains near Revelstoke from the evening of Thursday August 8th through to Sunday August 11th: http://members.shaw.ca/botanybc/
Our main headquarters for Botany BC 2013 will be in the hall at the charming and centrally located Revelstoke Senior's Centre, 603 Connaught Ave. Revelstoke.
Both BOTANY ALBERTA and BOTANY BC will offer a number of hikes, including sightings of whitebark pine, limber pine, numerous other rare plants, bryophytes and lichens, and of course. incredible mountain views.
The idea that a balanced and diverse investment portfolio is important to preserve capital investments, promote growth and mitigate the risks of financial losses in a volatile economy has long been promoted as the best strategy towards financial health. A recent study published this week in Nature brings scientific validation to the long-held belief of ecologists that the nature works in this same way. Ecosystems are better able to recover from disturbances when biological diversity is high. Nature doesn't put all of its eggs in one basket either.
The 10-year study, conducted by researchers at the Department of Integrative Biology at the University of Guelph and the UBC Center of Biodiversity Research under the leadership of Dr. Andrew MacDougall tested the theory that even apparently healthy and productive natural areas around the world are vulnerable to sudden and catastrophic collapse if they lack the very thing that enables stability when adapting to rapid change: diversity (MacDouglal, A. & al. 2013 - see the Abstract below).
As a conservationist and a scientist, I am gratified to see hard scientific evidence that supports the basic mission of nature conservation organizations and partnerships around the world: to protect, restore and enhance biodiversity. MacDougall conducted his study on the Cowichan Garry Oak Preserve on Vancouver Island, a property owned by the Nature Conservancy of Canada (NCC). The Preserve is a rare remnant of Garry oak savannah that once was much more common in the Pacific Northwest. Today only about 5% of this habitat remains. The rest has been converted to agricultural, residential and urban land uses. Many of the plants and animals that once thrived in the Garry oak ecosystems are at risk of extinction. Some have already disappeared.
When NCC bought the Preserve in 2000, it was far from pristine. The bones of the old native ecosystem were there, but many of the open meadows were overrun with non-native, invasive plants like Scotch broom (Cytisus scoparius), Common Hawthorn (Crataegus monogyna), and Himalayan blackberry Rubus armeniacus). Using every conceivable technique from cutting, weeding and mowing the invaders to replanting and seeding native species to conducting prescribed burns we are slowly restoring the original habitat and, in so doing, enhancing native biodiversity in the area.
The partnership with Dr. MacDougall provides him with a real-life testing ground for his research while also fulfilling NCC's management goals for the Preserve. I have witnessed first hand the way the land has responded to fire, one of the key methods Dr. MacDougall used to disturb the ecosystem in order to test its resilience. In the areas of the Preserve where we have restored the Garry oak meadows, complete with native grasses and wildflowers, fire was like the equivalent of a tall drink of water. The spring wildflower bloom that followed was a spectacular display of myriad colours, textures and sounds with thousands of native bees and butterflies literally vibrating the ground we stood on.
In places on the Preserve where restoration had not yet taken place and the meadows had long ago been converted to healthy and productive hayfields fields with only a single species of agricultural grass, MacDougall's fire was devastating. Within one growing season, invasive shrubs had completely taken over. The hayfield was even further away from functioning as a native ecosystem, and was no longer any good for agriculture either.
