Sleep-walking into Flooding Fragility

In just one of many illustrative examples in his book "Antifragile - things that gain from disorder" author Nassim Taleb talks about the irony of sports-shoe makers touting that their most advanced models are those that most closely replicate the bare human foot. This is fascinating since it highlights that attempting to smooth out and cushion the shocks experienced during running actually had the effect of massively increasing muscular and skeletal injuries from running . In barefoot running, the toes and arches of the feet act as shock absorbers and - crucially - allows them to be exposed to the action of running that actually strengthens them in this function. By contrast, the attempt to eliminate those specific stresses resulted in humans striking the floor with their heels rather than their toes and the additional padding robbed our feet of the varied "training" that prevents things like fallen arches and plantar fasciitus. Another example favoured by Nas...

Sheffield Has a Formal Strategy for its Waterways; Incorporating its Urban and Rural Catchment areas

Some readers may have already seen the various pieces that I've contributed on managing surface water in urban and rural catchments (e.g. videos embedded at the bottom of this post) alongside the organisational role to Sheffield's first One Big River event. This was a week of activities focused on the rivers of the Steel City and was timed to coincide with both the River Restoration Centre's Annual Conference (held for the first time at Sheffield Hallam University: http://www.therrc.co.uk/rrc_conferences.php ) as well as the formal signing (and Cabinet adoption) of the Waterways Strategy. The various community and volunteer events that formed the week-long programme ( https://sites.google.com/site/sheffieldonebigriver/main-events-program included a family-day of riverside events run by the Sheffield branch of the Trout in the Town project (SPRITE) and the Wild Trout Trust. Everyone involved really enjoyed talking to local residents and visitors and showing them the l...

Sheffield Beneath The Waterline

Wildlife photographer and videographer Jack Perks visited Sheffield yesterday as part of his bid to document as many of Britain's freshwater fish species as he can. Some of these species face an uncertain or bleak future - and Jack's project ( http://www.btwlfishproject.com/ ) could be the last time that they are possible to document on film. On this, his first recce visit, I took Jack on a whistle-stop tour of a number of locations spread across the city; ranging from retail/city-centre areas, heavy industry zones and suburban sites. Jack's VLOG gives a snapshot of his visit below:  

Meeting United Utilities with Salford Friendly Anglers - part of the Trout in the Town family

Valuable proof that anglers and community interest groups can be taken seriously by large companies (as well as government bodies) was ably demonstrated yesterday during a meeting convened by the formidable Mike Duddy of Salford Friendly Anglers (centre of picture above). Discussions over the current (and future-planned) status of a range of Combined Sewer Outfalls on the Irwell system were held at Mike's offices in Salford. Presentations by network managers and external affairs representatives of United Utilities (the local water supply company) were combined with debate over conditions in and around the river. I'm pleased to have been able to support the group in getting to the stage in the discussions through some assistance in data crunching and interpretation that allowed the "priority" discharges affecting their rivers to be identified based on reported chemical discharge information. Coupled with detailed local knowledge from anglers such as Arthur Hamer o...

Detailed introduction to how Erosion and Deposition in rivers provides a home for wildlife

Perhaps topical given current examples of river-bed-transporting extreme flows happening in many parts of UK... In a striking similarity to the widespread lack of understanding of the impacts of dredging on flood risk - the problems caused by weirs that choke off the downstream progression of river gravels, cobbles, sands etc. are not widely appreciated. The presentation below gives a basic outlining of why everything that lives in our rivers depends on the capacity for river channels to continually transport (and periodically deposit) river bed material from the hilltops to the sea. If we work better with (rather than against) these processes it would be far better for both societal needs/costs and the natural world.

Universal nature of risks with Wild Brood Stock, egg-boxes and similar supportive breeding schemes

Although extremely counter-intuitive upon first sight; trying to help wild populations of (for example) trout by boosting their reproduction actually has many more chances to go wrong than to actually help. There is a lot of coverage devoted to the various aspects of this in some of our WTT guidance pages ( http://www.wildtrout.org/sites/default/files/library/Stocking_position_2012_final.pdf ) But as a really readily understandable example from the world of bird conservation; we can see just one of the prominent pitfalls of giving an artificial helping-hand to breeding success. The nub of it is that if the boosted numbers are made up of individuals that the natural environment would otherwise kill off; you risk actually pushing the population closer to extinction (or permanent reliance on human intervention). The story below and trout-specific research should give serious pause for thought to any club assuming that the best response to the Trout and Grayling Strategy (which will pr...
