On 6 September we had an excellent and informative presentation from Professor Steve Ormerod introducing the findings from his 40 years of work studying the streams and rivers of the Cambrians around Llyn Brianne.  The conclusions were encouraging: with enough care, many of the changes already caused by acidification and rising temperatures can be mitigated.  The number one remedy is planting broadleaves along the sides of streams to add shade and, through leaf fall into the waters, nutrients.  Watch the video of the webinar above, and for more detail, see the plethora of Professor Ormerod’s papers available for free online through researchgate.net.
