You've done a big, ambitious partnership project to deculvert a section of urban stream, but now the civil engineering contractors have gone to their next job. The site is left to mature...what next? Very seldom does this kind of project have any budget for ongoing ecological monitoring (which is a frequent and justified criticism of habitat improvement works - the lack of ecological effect data).
The same can be said for general "husbandry" of the site - whether it be litter or invasive plant control; or even fairly substantial running repairs...
Step in SPRITE (Sheffield Partnership for Rivers in Town Environments) whose site you can check out on http://www.sheffieldsprite.com, the Sheffield Trout in the Town group and a supporting donation of pre-established planted coir products from Salix River and Wetland Ltd. (with their site here: https://www.salixrw.com)
You can see SPRITE talking about their aquatic invertebrate monitoring and see their repair and site care works in action in the embedded video below:
