Ham Wall is of value for its habitat and water treatment potential, but methods to cost diffuse water pollution treatment are not available. Other values, such as for otter, bittern or fish habitat have not been included, even if they could be calculated. Planting time was estimated at 540 person hours ha -1 at this density. Stems Costs were that of personnel to cut, transport and plant reeds. Working in pairs is best.
Costs are for dumper truck and bucket excavator hire, plus personnel time.
150 rhizome loads took 38 person hours, costs are based upon this rate of work. This is very hard to estimate for costing due to variable seed viability, however, for 1 ha, it is estimated that 800,000 seeds are needed. Personnel time required is approximately 7 h to collect and treat the seed and 1 h to sow 1 ha. The development of reedbed systems at both sites was challenging and exciting and mainly successful in achieving the objectives set. Both reedbed systems perform well in different respects and both appear to be capable of providing long term benefits to their local environment.
