Hoveton Wetlands Restoration Project Hoveton Marshes Breeding and Non Breeding Birds Survey Method Statement

Overview Natural England is currently leading a project to carry out lake restoration at Hovetori Gr<^at Broad aTicJ" Hudson's Bay on the River Bure. These Broads are situated within the Bure Valley, downstream of Wroxham, Norfolk. They form part of the Bure Broads and Marshes SSSI, which in turn is a component Site of Broadland SPA, The Broads SAC and Broadland Ramsar Site. They also form part of the Bure Marshes NNR.

Both Broads are currently assessed as being in 'unfavourable no change' condition and are failing to meet 'good' ecological status, as defined under the Water Framework Directive (WFD), despite significant improvement in the water quality of the adjoining river Bure. Assessment of historic water quality data suggests that in-lake cycling of nutrients is the main reason for the poor condition of these waterbodies. The outline proposal is therefore to remove the majority of nutrient-rich sediment from both Broads. It is hoped that this will in turn significantly reduce total phosphate concentrations. The lakes will then be isolated from the river and dyke networks and biomanipulated to 'flip' them back into a clear water macrophyte-dominated state.

As part of this we received planning consent for the creation of a boat trail through Hoveton Marshes.

In approving this application the Broads Authority have imposed a condition which we are now looking to satisfy:

Condition 14.* Prior to the first use of the canoe trail hereby permitted, the results of two calendar years of breeding and non-breeding bird surveys of the proposed route and adjacent habitat (defined as the area 25m either side of the route) shall be submitted to and agreed in writing by the Local Planning Authority. Reason In the interests of protecting the ecology of the site in accordance with Development Management Policy DPI.

This report details the method statement which will be used for the non-breeding and breeding birds survey.

Survey Methods

All surveys will be conducted for two calendar years as required by condition 14.

Non breeding bird survey The survey method will be based on that used by the national annual Wetland Bird Survey (WeBS). WeBS is a partner scheme of the British Trust for Ornithology (BTO), Wildfowl and Wetlands Trust (WWT), RSPB (Royal Society for the Protection of Birds) and JNCC (Joint Nature Conservation Committee) and relies on a network of several thousand volunteers who survey most estuaries and inland water bodies once a month on set dates autumn through winter.

The survey will be conducted in the morning using one visit per month from September to March on predetermined dates to coincide with the national WeBS. Where visibility is significantly reduced by bad weather survey visits will be postponed but still conducted as close to the pre-determined WeBS date as possible. Additional survey may be conducted during any period of harsh weather in order to identify if this affects the distribution of birds in the area.

The proposed routes of the boat trail will be the primary focus for survey and all bird activity noted within 25m of the routes will be recorded on a map. Bird activity in the wider area will also be recorded when the species involved may be likely to also use the route habitats.

The survey will involve observations from a canoe paddled through the relevant ditches and vantage point counts from adjacent dry land and from the top of the old Didler's Mill building on the eastern side of the route. Binoculars and/or a telescope will be used for detailed observation of birds and their behaviour.

Breeding Bird Survey The breeding birds survey approach is not a generic methodology but is specific to the proposed boat route and the range of important species that could breed within the habitats to be affected. The methodology has been produced in consultation with staff at the RSPB and using guidelines set out in Bird Monitoring MethodsV

The survey will be conducted over eight daytime surveys and two nocturnal surveys. In addition should marsh harrier be identified as possibly breeding within the survey area an additional two surveys will be conducted to confirm the presence of fledged young later in the summer. It is important to note that surveyors have a high probability of disturbing schedule 1 species such as marsh harrier, bittern or bearded tit and will be licensed accordingly.

During any survey all bird activity observed within 25m of the proposed boat route will be recorded on a map of the area. Bird activity in the wider area will also be noted when the species involved may be likely to also use the route habitats.

Daytime Survey Daytime surveys will be started an hour after dawn and will finish no later than 11am. Each survey will involve observations from a canoe along the boat trail route and vantage point counts from adjacent dry land and Didler's Mill. The order of survey from these locations will be altered between surveys to avoid bias resulting from the time of day.

There will be three visits In April, three in May and two in June. If marsh harrier is identified as possibly breeding, two additional visits will be conducted in July to identify the presence of any fledged young

Nocturnal Survey Nocturnal surveys will be conducted from land adjacent to the proposed boat route and will begin at dusk, survey duration will depend on levels of bird activity but will be approximately two hours. There will be a nocturnal survey in April and another in May. Additional nocturnal visits are not considered necessary as most crepuscular species will also be observed around dawn when survey will commence.

Results The maps produced during survey will be collated and refined and will be used to identify the species using the proposed boat route area and approximate population sizes. These details will then be provided in a report with the maps appended.
