Alaska’s lakes, streams and forests are, in many cases, much as they were before the industrial age, with the same species of trees, plants, fish and animals that would have been found here centuries ago. That’s all in danger of changing. Invasive plants on land and water can spread rapidly. It has already happened elsewhere in the US, often with devastating impacts on natural ecosystems. Here, there is more of a chance to snip the problem in the bud before it spreads too far. Weeds entering a new system are something like viruses, or cancers, that can be dealt with relatively easy in the early stage, but become unmanageable if they go too far. The hopeful news is that Alaskans are tackling this challenge, and it is not too late to make a difference. We’re learning about invasives on this episode of Outdoor Explorer.
