|Project summary=The Test and Itchen River Restoration Strategy is a long-term project being carried out on these two world-renowned chalk streams in Hampshire. The Rivers Test and Itchen are legally protected as SSSI’s as they are two of the best remaining examples of chalk stream river types and associated habitats and species. However, condition assessments undertaken by NE of the riverine Site of Special Scientific Interest (SSSI) units in March 2006 on the River Test and March 2010 on the River Itchen, the outcomes showed that both the SSSI’s are in unfavourable condition. The key reasons for this include historical modifications to the physical structure of the channel, banks and riparian zone. The Wildlife and Country side Act 1981 and the Water Framework Directive (WFD) require the rivers are returned to favourable condition and good ecological status, respectively.
The aim of the T&I Strategy is to appraise the geomorphological condition of the rivers, identifying the condition of the rivers in relation to their ‘natural benchmark’. From this starting point river restoration, rehabilitation and conservation/ enhancement actions can take place to restore the SSSIs and bring them into favourable or unfavourable (recovering) condition. This includes the following specific objectives.
1. Determine the impacts of physical modification on the geomorphology and ecology of each river;
2. Provide an outline restoration plan for each river on a reach by reach basis;
3. Identify potential delivery mechanisms to help achieve this.
The focus of any restoration project within the T&I Strategy is to ensure the condition of the habitat rather than the preservation of the species directly, with the principle being that good chalk stream habitat is more likely to support characteristic flora and fauna. Although the Strategy is primarily aimed at in-river characteristics, it’s also recognised that land management adjacent to the rivers has the potential to affect the quality of the in-river habitat and has been given due consideration to this throughout the project.
The main objective of the T&I Strategy is to deliver the recommendations and aims above by working collaboratively with landowners and fishery interests.
The T&I Strategy was first initiated in 2010 then due to unforeseen and tragic circumstances stopped. It was then re-started again in 2012. Given the scale of the T&I Strategy it is expected, all going well, that it will continue over the next 20-30 years.
|Monitoring surveys and results=Surveys of macroinvertebrates, macrophytes, fish communities and juvenile salmonids are conducted by the Environment Agency before and after restoration work on some reaches. In some cases River Habitat Survey, HabScore, and MORPH surveys have also been carried out.
Extensive before and after surveys have also been carried out by external parties. For example, Southampton University PhD students have been monitoring some restored sites for several years (yet to be published) and Sparsholt College students have carried before and after fish surveys on the River Test.
One technique used to record change has been before and after photography. Images have the power to show dramatic change between before and after completion.
At one reach the Environment Agency asked anglers to complete a questionnaire which will be repeated to determine perceptions of the river before and after restoration. This is more than just a satisfaction survey, as it seeks to capture emotions and values.
Feedback from land and river-owners and river keepers is crucially important to evaluating the works and shaping future schemes.
To date all the flora and fauna survey work has shown the benefits of each restoration and that the goals and objectives of the strategy are being achieved.
|Lessons learn=Good communication with the numerous landowners on the Test and Itchen is key to the success of this project.

{{Measures
|Bank and bed modifications measure=This project took place on the River Test at Overton, Hampshire (SU50953 49769) in autumn of 2017. The report by Atkins in 2012 identified this stretch as needing restoration. The report had broken the river into reaches. Each numbered reach had the problems associated with that reach and the restoration actions needed to restore it. In the case of reach T009 an historic structure was impounding several hundred metres of channel to the detriment of the SSSI. The aims of the project were to improve 400m of river, restore the reach from a silty canal to a naturally flowing channel and provide fish passage by removing the structure while at the same time being sympathetic to the history of the site.
|Social measures=One of the most enjoyable parts of this restoration was working with and involving the local community. This came about because of the experiences gained in 2016. In 2016 given the location of the restoration through Overton village the owner and contractor where advised to let as many people know about the project so they knew what was happening. While this instruction was carried out many local people where still shocked as to the scale of works. Many non-indigenous tree where felled to allow light into a previously over shaded channel and consequently the view for many locals changed dramatically. Following local concerns Heb Leman the Project Officer gave a presentation to the local community on the background to the Strategy and consequently why the works where being carried out. After this the local community embraced what was being done and wanted to be informed of any future works. Once the landowner had agreed to continue the works upstream in 2017 and remove the structure a guided tour was arranged for residents. This showed them the already beneficial changes to the restored channel and informed them of what was going to happen in 2017. To involve them further it was decided that the Overton Biodiversity Society would carry out the water vole surveys prior to the work and that the community would be kept informed of the new works via the community Face Book page. The landowner also agreed that because of the historic and archaeological interest in the site that Overton Archaeological Society could also carry out a dig during the works. Consequently throughout the works local archaeologist worked alongside County archaeologist piecing together the history of the site. On completion of the works all the finds and the long history of the site where presented to the local community through an evening of presentations on the restoration itself and the history of the site. This event was attended by at least 120 people and was very well received. From this also came further potential restoration works with others wanting to be involved. The whole experience also engaged the wider community with the landowner for the benefit of all. Other external inputs came from colleagues specialising in fish passage. This was a technically challenging project and the finished project had to enable up and downstream fish passage. Their knowledge was invaluable in allowing this happen.
