Bracken - fronds uncurling
Have you ever seen a bracken leaf uncurling? Well down in the wood you can!
There are concerns about the spread of bracken because it contains a chemical, ptaquiloside, that if it enters the water supply could cause digestive problems or even cancer. This chemical is tested for by our water company, Welsh Water, on a routine basis.
It is ok for bracken to be growing in the woods, but it will cause illness in horses and cattle so we need to ensure it does not spread too far into the fields!
Still I think the plant is amazing to see at this time of year!
