Pre-restoration appraisal including electric fishing survey, macroinvertebrate sampling and fixed point photography on the River Ash in Middlesex. Where possible we try and build in pre and post monitoring for our river restoration schemes to build up a sound evidence base for future works. We’ll be back in twelve months to evaluate the success of the scheme.
We’re looking forward to the 2016 River Restoration Conference, an Annual Network Conference which this year is being held at the Imperial Hotel, Blackpool on the 26th & 27th April. Come and find us at the Five Rivers Environmental stand.
We are one week into a ten week turf translocation project to move 8ha of unimproved mesotrophic grassland in the Midlands, the donor can be seen on the right at the end of the rainbow. Due to ground conditions considerable resource has gone into installing a haul road using over 1000 tonne of stone and 300 bog mats that will ensure we can work in all weathers. This investment early on in a project ensures smooth delivery for habitat translocation projects, and mitigates for constant risk of poor environmental conditions delaying works. Get in touch to discuss the habitat translocation services we offer.
We have recently had a team out starting a river habitat improvement project on the River Ash near Shepperton. Phase one involved notching a concrete weir to improve fish passage and longitudinal connectivity. Today we are building a oak control structure to maintain levels in connected lake, then we’ll be back in August to restore an historic mill leat into a fish by-pass channel. Weir notching is quick and simple procedure that can have massive benefits to a catchment, this is one of many fish passage solutions we can offer. Contact us for more details.
We have been busy carrying out enabling works in centre of Salisbury prior to replacement of 180m oak revetment with a mixture of soft, semi-soft and hard revetments. This will increase bank protection and improve habitat for a wide range of species that utilise this important marginal zone. These sympathetic tree works will allow more light in to the river edge, and allow the range of native marginal plants we install to thrive and hold the banks together. This site is in a Conservation Zone, and Special Area of Conservation so careful consultation has taken place with all stakeholders over the last twelve months. We are looking forward to getting back in the summer and finishing the works, especially working so close to home!

Five Rivers have been busy carrying out clearance of natural regeneration and invasive woody species at multiple sites in the New Forest over the last couple of months, what a great place to be working!
Habitat restoration work is undertaken for the Forestry Commission (FC) to maintain these important habitats in good condition, which is necessary for continued Special Area of Conservation (SAC) designation.
Signal crayfish Pacifastacus leniusculus remains found in Otter spraint at Breamore on the Hampshire Avon. By looking at prey remains in river otter spraints ecologists are able to gain valuable insights into the diet of this enigmatic mammal. This otter had been feeding on perch, small pike and small mammals as well as the non-native invasive signal crayfish.
Signal crayfish have been in the Hampshire Avon for a number of years now but are yet to reach the numbers found in other catchments such as the Kennet and Lee. North American crayfish species carry a fungus like organism known as crayfish plague which has decimated our native crayfish populations across the UK. Five Rivers are able to provide Natural England licenced ecologists to survey for White-clawed crayfish Austropotamobius pallipes, please get in touch to discuss how we can help.
Making the most of the sunshine today, a few members of the Five Rivers team popped down to the river to help Mel with her Riverfly Monitoring.
With a BSc degree in Wildlife and Countryside Management Mel enjoys an active role in protecting the health of the local rivers by monitoring riverfly populations. Five Rivers offer a macroinvertebrate sample collection and analysis service. Contact us for more details.
On a recent walk along the banks of the River Nadder we found this hen fish whose long migratory journey has ended abruptly but not in vain; providing a food source for a thriving river Otter population.
Its great to see so many Salmon in the river this year – lets hope its a good sign for the future.
We’d like to wish all our customers a happy new year, and we look forward to working with you all again in 2016. We’ve got interesting projects lined up over the next couple of months including River Restoration and Forestry works. This week we’re busy in the New Forest helping clear natural regeneration from the Heath. This forms part of our wider work for the Forestry Commission to protect and enhance the important habitats found in the New Forest.
