Project summary

Edit project overview to modify the project summary.


Reedbed creation, profiling of river bank, tree management, installation of eel passes and stocking of fish in adjacent ponds at Hampton Court Palace, Home Park Paddocks. Main reasons for enhancement were habitat creation, landscape and aesthetics. Riverbank enhancement, and potential to demonstrate traditional management methods with modern knowledge and technology to show improvement to flood meadow function and water quality.

The final part of the Home Park project completed using funding from CPAF15/16 was partnership working between Thames Landscape Strategy, Thames21, and Historic Royal Palaces. Three new eel passes were constructed and installed on the Longford River to enable the passage of elvers from the Thames into ponds on site, with urther marginal planting installed on the Long Water Canal.There was the use of Shire Horses, cutting of bankside vegetation and extraction of timber for senestive land mangement practices, and the removal of a number of self-set Norway maple trees from the banks of the Longford River to reduce shading of the river system and to allow marginal vegetation to establish,and restocking crucian carp.

The project involved local communities and volunteers to help with monitoring the success of the project, and promote awareness of the Maidenhead to Teddington Catchment.

Monitoring surveys and results

Edit project overview to modify the Monitoring survey and results.


Monitoring of nitrates and phosphates and surveying of wildlife on going. To be undertaken by Historic Royal Palace Staff, local conservation groups, volutneers, and local community trained by Thames21.

Lessons learnt

Edit project overview to modify the lessons learnt.


Project timing is essential to maximize benefit. When to cut vegetation, when to plant, what time is best to carry out re-profiling to limit disturbance,when it is best to work with local communites, schools in particular and those with more fixed schedules, and the fact that projects must be allowed to be flexible enough to alter perimeters should the need arise within these timings.
