The term "invasive species" may not sound very threatening, but these invaders, both large and small, can and do have devastating effects on wildlife and communities across the world.
Invasive species are one of the most threatening problems to native wildlife, with approximately 42% of endangered species at risk as a result of invasive species. Endangered species aren't the only things that are at risk due to invasive species, however, with economies and human health also susceptible to feel the effects. The impact that invasive species have on our natural ecosystems and economy cost billions each and every year, with many of our recreational, agricultural and commercial activities heavily reliant on healthy native ecosystems.

Salt is very versatile - it can make virtually any meal taste better - but sadly, there are some problems that salt can't solve.
You may have heard that salt can be used to kill garden weeds, and there is some truth to that. Applying salt to an unwanted plant can cause the plant to dehydrate and ultimately die.
But should you actually try this? The RHS don't recommend it: "The use of bleach or salt to kill weed on paths and drives is strongly discouraged, as this can cause pollution and damage plants."
Besides, Japanese knotweed is no run-of-the-mill garden weed. It takes a lot to eradicate this invasive species once and for all - a mere sprinkling of salt just won't do it!
