Local groups tackling invasive species CAN help global biodiversity

We trout in the town types occasionally come in for some snide comments regarding playing round the edges of things at a local scale when we do volunteer balsam bashes and contract knotweed stem injection work. Well, as our own experiences with recovery of native seedbank plant species following the removal of Himalayan balsam concur, there is also now peer reviewed published science that indicates Global plant diversity can hinge on local battles against invasive species. It also explains why some of the previous literature can, sometimes, give conflicting conclusions depending upon the scale at which studies measured diversity.

Why Presume to Remove Weirs? (with River Dove Case Study)

Weirs and the Backwards Ways that Rivers Work One of my favourite sayings on river restoration is a mangled quote from a movie "... boxing is an unnatural act. Everything in boxing is backwards: sometimes the best way to deliver a punch is to step backwards...but step back too far and you ain't fighting at all ". So my mangled version starts out "Everything in rivers is backwards...". Basically, I never seem to run out of new examples of "what SEEMS to happen in a river is actually the complete opposite of what really happens". The rest of this article looks at many of the "backwards" things about weirs and rivers - and finishes off with a real-world case-study that is playing out right now on the River Dove . One spoiler alert is that, from an ecological point of view, it is almost always safe to assume that: The best biological outcome for a river is the removal of some or all of an artificial weir.  Now, I don't exp...

World Rivers Day 2017 (Grantham)

I had the great pleasure of participating in a fantastic event in the lovely setting of Wyndham Park in Grantham on the River Witham for World Rivers Day 2017. As well as drawing attention (and deserved accolades) to the habitat improvement works carried out in partnerships between Lincolnshire Rivers Trust, Environment Agency and the good ol' Wild Trout Trust, it was a great chance for enjoyment and learning. Tons of stalls, tours of the habitat works, invertebrate samples in tanks, Model Rivers, Fly casting with Peter Arfield and Tenkara casting with myself - even an epic pooh sticks race off the bridge in the park. The weather was kind too. Many thanks go to Professor Scrubbington’s Emporium of Clean for supporting the WTT stand and making sure everyone went home sparkling clean! Throughout the day there was a steady stream of visitors either strolling through the park and becoming engaged in the activities or folks who had seen the social media advertising and...

The Wild Trout Trust: A Film by Chalkstream Fly

Here is a great short piece that captures what the work of the Wild Trout Trust is all about. It was made for (and broadcast on) the very first "World Fishing Day" - a 24hr live fishing programme created by FishingTV.com . It features TV personalities (and WTT President & Vice President respectively!) Jon Beer and Matthew Wright as well as Director of the Trust, Shaun Leonard. You can see more work by the film-makers on Chalkstreamfly.co.uk  and, of course, you can join the Wild Trout Trust here: WTT Membership Paul Gaskell (Trout in the Town Conservation Officer)
