The Environment Agency has looked again at the question of trees in the Oxford Flood Alleviation Scheme (OFAS) – this is from their recent newsletter:
‘We have listened to local concerns about the impact the scheme will have on trees and recently conducted some additional tree surveys. Although trees will unfortunately have to be felled during the construction stage, we can confirm that our tree-planting proposals will ensure there will be more woodland within the scheme area after completion, than there currently is at present.
By surveying individual trees by eye, we estimate that 2,000 trees will need to be felled. To mitigate for this we will be planting around 4,325 trees. In addition, 15,000 smaller trees, such as hawthorn, hazel and elder, will also be planted, along with many more native shrubs such as dogwood, goat willow, dog rose and wild privet. Throughout the design process, our contractors, engineers and ecologists have worked together to minimise tree loss wherever possible. Once a contractor has been appointed we will work with them to further minimise losses of trees wherever possible.
Our aim is for the scheme to bring a true green legacy to the area. We are currently exploring options for the long term maintenance of the scheme to ensure it is not only maintained as a flood scheme, but continues to provide lasting environmental improvements well into the future.’

The Oxford Mail today carries an article about the Freshwater Habitats Trust’s (FHT) very positive involvement with OFAS:

Two letters in today’s Oxford Times.
One from us on the fact that extra capacity is simply not needed.
See too the recent parking spaces data in an earlier post.
Would not live signs on the ring road, showing availability at the park and rides be a good idea, optimising the usage of the substantial existing capacity?
Contrary to claims in the Application, our analysis suggests that, for traffic from the south, in terms of time taken to reach the car park from the A34, Redbridge (the bigger of the two) is almost always a quicker option than Seacourt.
The other letter is from Adrian Rosser on the extensive clearance that’s been going on on the site before the Planning Committee has even met to consider the application.

Common Blue Damselfly (Enallagma cyathigerum), female.
Attended an environmental update meeting yesterday, organised by the EA with a number of local environmental stakeholders attending. A lot of thought is going into making the most of possible environmental enhancements that the Scheme can bring.
Led by Penny Burt of the Environment Agency we covered surveys, ecological trial areas, archaeology, low-flows and existing watercourses, fish passage, Hinksey Meadow, trees and bridges, habitat creation and access. Also mentioned was future maintenance – we felt that the plans were not nearly long-term enough and this was discussed.
For our part we are working closely with the Freshwater Habitats Trust. The Oxford area is rich in freshwater species, though there is, nevertheless, a long term decline: this Scheme could help reverse that trend. We’d like to give the public, including school children, a chance to be involved, including with data collection in the field – sometimes called ‘citizen science’.
The damselflies in the photographs are closely associated with the freshwater habitat.
Talk on 29 June by Jeremy Biggs of the Freshwater Habitats Trust
Jeremy Biggs gave an interesting and inspiring talk, ‘Oxford and the Thames: a national hotspot for freshwater wildlife’, in South Hinksey yesterday; it was well attended by professionals and members of the public alike.
The overall message was that the Oxford area, including (but much wider than) the area of the OFAS channel, is of relatively high quality (on a national scale) for freshwater wildlife. Nevertheless, there have been local extinctions and a gradual decline over the last century. Clean, unpolluted water is vital to any attempt to reverse the decline.
A lively discussion followed.
To make the most of the possible environmental enhancements from the OFAS scheme more detailed proposals will be developed. More could be achieved if additional, separate funding could be obtained. Such work could make a contribution to reversing the gradual decline and enable lessons to be learnt as to how to do this best.
