Just as leafy spurge looks harmless but is really an invasive species, purple loosestrife is another attractive-looking plant that can do more damage to the local environment. Purple loosestrife is a wetland invasive species that has taken over the river systems in Eastern Canada. While it looks like a beautiful flower, it is extremely aggressive and can wipe out cattails and other native flora. If its seeds spread, they can choke out wetlands. Purple loosestrife is native to Europe and Asia and was brought to North America in the early 19th century. It was likely introduced when its seeds were included in soil used as ballast in European sailing ships and discarded in North America.
Experts calling for watershed monitoring in the Columbia Basin amid climate change concerns
After a record-breaking summer of heat, drought, and fires, experts in the Columbia Basin are stressing the importance of water monitoring and watershed management to secure our water supplies. “Watersheds are complicated,” said Greg Utzig, a conservation ecologist based in the Columbia Basin. “There are lots of different pieces, and if we are going to understand how these watersheds react to climate disruption, we have to have a better understanding of how the various parts interact. This is where water monitoring comes in, by helping us understand how these systems work and how fast they are changing,”
Water stewardship group: groundwater levels lower this year in Columbia Basin
Non-profit water stewardship organization Living Lakes Canada (LLC) says that the hot, smoky and dry conditions experienced throughout the Columbia Basin over the past summer aren’t the only indicators of accelerated climate change, and that low groundwater levels have also shown a decrease in some aquifers from last year to now. Groundwater data is obtained from aquifers LLC monitors as part of their Columbia Basin Groundwater Monitoring Program. An aquifer is an underground layer of broken rock, gravel, sand or silt that contains groundwater.
