The more diverse an ecosystem, the more resilient it is in the face of adversity. This is among the firmest precepts of biodiversity, and is without doubt one of my favourite. The more intact our wilderness, the more of its native species remain alive and well and active in the workings of ecology, the more prepared we will be for the incursion of invasive species plaguing North America, for the apocalyptic consequences of unfettered climate change, for the policies of regressive administrations which seem only too common these days. It’s as strong an argument for conservation as any I’ve ever heard, allowing us not only to maintain the functionality of the world which sustains us, but the beauty inherent within.
Point Pelee has always been unique among Canada’s national parks. It was the first to be established for primarily conservation purposes in 1918, its importance to the migratory songbirds of North America made evident by local ornithologist Jack Miner and others. Because it jutted so far south into Lake Erie from southern Ontario, it offered birds flying north their first opportunity to make landfall in Canada, sharing unorthodox company on this 15 square kilometre spit of land for a few weeks before scattering across the Canadian north.
Joel Salatin of Polyface Farm, Virginia, was featured in both the New York Times bestseller The Omnivores Dilemma and the documentary Food Inc. for his farm’s unique and holistic management, servicing more than 5,000 families, 50 restaurants, 10 retail outlets and a farmer’s market with organic beef, pork, poultry and forestry products. What’s more, he’s published 12 books.
The Eastern hemlock is a force of nature in Nova Scotia by virtue of its age. Foresters past and present have ignored it in favour of more valuable spruce, pine and myriad hardwoods, allowing hemlocks to become the oldest member of our enduring forests, accounting for almost all of our remaining old growth.
The entire global population of Atlantic whitefish is restricted to a single watershed in southern Nova Scotia, and in the minds of many, even this haven is no longer safe.
I was caught off guard recently when someone assured me that invasive species are no big deal; that, when it comes to the mass extinction we humans are driving forth, taking a couple thousand species from one unique ecosystem and plunking them in another won’t matter much in the long run.
It was the 18th of August when I gained the summit of Mont Jacques-Cartier, an alpine peak of shattered stone and meager vegetation some 1,270 metres above Quebec’s Gaspé Peninsula. Several stones were organized into mounds marking the trail all visitors were obliged to follow, and just beyond them, lounging in no-man’s-land with a mountainous backdrop, were the very last of the Atlantic caribou. Here was the end of a very long pilgrimage, for me, but more so for them.
The entire global population of Atlantic whitefish is restricted to a single watershed in southern Nova Scotia, which is as alarming a statement as I am capable.
There was a time when American beech commanded much of the Maritimes, growing to tremendous sizes with porcelain smooth bark, a generous abundance of seed and autumn beauty to rival any hardwood. But that’s not the American beech we’ve come to know, seeing instead a tree corrupted by black rot, its bark twisted and cankered beyond recognition, stunted and with very few seeds. In little over a century this species fell from canopy heights, now a leper among plants.
The concept of biodiversity is relatively new to the mainstream, proposing that ecosystems can be appraised, so to speak, based on the variety of organisms they support. It states simply that a healthy forest cannot contain solely Balsam fir, nor a healthy river exclusively Atlantic salmon.
