We provide practical advice, grounded in science, on how best to safeguard England’s natural wealth for the benefit of everyone. Our remit is to ensure sustainable stewardship of the land and sea so that people and nature can thrive. It is our responsibility to see that England’s rich natural environment can adapt and survive intact for future generations to enjoy. We work with farmers and land managers; business and industry; planners and developers; national, regional and local government; interest groups and local communities to help them improve their local environment. 1. Introduction Dozmary Pool SSSI is an ancient natural moorland lake, unique on Bodmin Moor in having shown very little natural succession to bog and marsh. It is the largest natural freshwater lake in Cornwall and is at an altitude which makes it without parallel in the south-west. The underlying granite yields a nutrient-poor soil which supports a mosaic of acid grassland and heathland in the surrounding areas. The lake is oligotrophic supporting a characteristically limited flora including nationally scarce species of higher plants. Phosphate levels in the lake are currently well above levels expected for upland oligotrophic lake (total phosphorus (TP) annual average should be 10 µg/l or less). We require a contractor to develop a nutrient budget (both P and N) for the lake by carrying out repeat water quality sampling where necessary to compliment routine data collected by the Environment Agency, hydrological analysis to understand the water budget and quantification of the main sources of nutrient inputs (primarily cattle, geese, fertiliser and septic tanks) through a combination of direct measurements where required and export co- efficient modelling. Cattle graze the adjoining heathland and spend time in the lake itself, while flocks of geese have been reported at intervals feeding on the shore. Remedial action will be required in the long-term to reduce phosphorus levels; this will require proportionate action on the range of different nutrient sources. Establishing a nutrient budget for the lake and catchment is a key step in determining where action is best targeted to reduce nutrient enrichment of the lake, and the benefits this might offer for water quality. In addition, this study should draw on the results of the nutrient budget to recommend any management actions required both on site or within the catchment to reduce nutrient levels. If further investigation is considered necessary before management action can be targeted, the further work required should be identified. 2. Objectives: The objectives of the project are to: 4 1. Establish a phosphorus/nitrate budget/source apportionment for the lake and catchment. 2. Produce an outline lake management plan incorporating the results of 1 and providing an evaluation of where reductions in phosphorus load will be required to meet the relevant phosphate target. Potential management actions should be prioritised in terms of their effectiveness in reducing phosphate inputs to the lake in the long-term. Detailed advice is required on the extent to which actions need to be implemented to bring down phosphate levels to the required levels over (eg excluding cattle from the lake year round or reducing numbers by 50% etc). If further investigation is required before management conclusions can be drawn in some areas, this should be specified and estimated costs for any extra work provided. Lake SSSIs do not currently have targets for nitrogen, but a recommendation for nitrogen load should be suggested based on keeping algal growth in check and in-keeping with this oligotrophic lake type. 3. Addressing Objective 1: Work Programme The main steps are as follows: 1. determine the current annual mean total phosphorus and nitrogen concentration for the lake using available information; 2. estimate the current phosphorus and nitrogen load to the lake from all sources (consented and unconsented point sources, diffuse sources, internal loading) 3. establish the critical phosphorus load that would result in the lake complying with the relevant phosphorus standard; lake SSSIs do not currently have targets for nitrogen, but a recommendation for nitrogen load should be suggested based on keeping algal growth in check and in-keeping with this oligotrophic lake type. 4. apportion the critical load between sources; and 5. recommend actions to reduce individual and overall loads to levels consistent with achieving the standard concentration. In many cases there will be inadequate data to inform all elements of the work (e.g. EA, MET office, published export coefficients). Therefore estimates will need to be made on the basis of both measured and modelled data. Detailed methodology Establishing the nutrient budget will require a collation of existing nutrient data & bathymetry data from the lake, data on catchment size, character, rainfall and land use and information on the hydrology of the lake (there are no inflowing streams). Other nutrient sources may need to be estimated ‘by difference’ or simple modelling. Where such estimates are used some indication of the confidence in results should be given. 1. Current TP concentration Compliance with the appropriate standard should be determined on the basis of a face value test using annual mean data (3+ years where available). The Favourable Condition Table for Dozmary Pool SSSI is currently being updated but the relevant section for water quality will follow the CSM standard guidelines closely (ie. The target is likely to be: Stable nutrient levels appropriate to lake type. Mean annual total phosphorus concentration less than target for appropriate
