True or false? Wine grapes may soon be growing around Yellowstone National Park in Wyoming. Wines from New Jersey are statistically indistinguishable from French wines. A little over a century ago, Algeria was the world’s largest wine exporter. China is the world’s fastest growing wine-producing country.
As it turns out, all of these statements are true — and each has an important lesson for conservation….
The area north of Yellowstone will be one of the areas with the greatest increase in suitability for growing wine grapes in the next 50 years. The reason is climate change. Temperatures are warming, and suitable lands for wine grape growing are moving north.
This shift may have a big conservation impact on the Yellowstone to Yukon Conservation Initiative (Y2Y), an innovative attempt to connect wildlife habitats between Yellowstone and Canada’s Yukon Territory. Vineyards would be a major impediment to this connectivity. They provide poor habitat for wildlife, and would probably have to be fenced to avoid bears snacking on the grapes.
These changes in North America are symbolic of changes happening across the globe. Wine suitability is moving toward the poles. In South Africa, Chile and Australia, there is little land left in the direction of the South Pole, and suitable area for vineyards is declining. In the north, there is a lot of high-latitude land, and area suitable for vineyards is expanding. This will result in a global redistribution of wine-producing regions, with some serious consequences for ecosystems and wildlife habitat.
