East Anglia ONE Offshore Windfarm Landscape Management PlanWork No 38 to 41
August, 2016
As required during dry spells for establishment only the intention is to create a sustainable grass sward not reliant on irrigation systems. If watering is required, due to unseasonably dry weather during the establishment period, then the contractor will need to arrange for a mobile water bowser or tanker to bring the required clean water to site.
6.5 Wet Grassland (G2) 88.
The aim is to create a healthy and full sward of wetland grass habitat (G2) within the SuDS Detention Basin. Details of the maintenance of the wetland grass areas are detailed in Table 6-4:
Table 6-4 Maintenance ofWetland Grass Wetland Grass Maintenance Cutting
1 Wetland habitats are characteristically quite variable in composition, reflecting local drainage and management. Conditions can vary and localized differences may require a targeted approach specific to the area in question.
2 First year management. Most of the sown species are perennial and will be slow to germinate. Avoid cutting in the spring and early summer if the mixture is autumn sown. Allow any annuals to flower, then in mid-summer cut and remove the vegetation.
3 In the second and subsequent years the grassland can be managed in a number of ways which, depending on soil fertility, will determine the character of the grassland. The best results are usually obtained by traditional meadow management based around a main summer cut in combination with autumn and possibly spring mowing.
4 Do not cut or graze from spring through to late July/August (to give the sown species an opportunity to flower). 5 After flowering in July or August cut to c 50mm. Leave the arisings to dry and shed seed for 1-7 days then remove from site. 6 Mow or graze the re-growth through to late autumn/winter to c 50mm and again in spring if needed. Weed Control Weed control will be undertaken as necessary to include spot herbicide treatment or manual removal. Watering
Unlikely to be required due to the type of grassland proposed (i.e. wetland grassland). However, should additional watering be required, then the contractor will need to arrange for a mobile water bowser or tanker to bring the required clean water to site.
6.6 Species Rich Grass Areas (G3) 89.
The intention of Species Rich Grassland areas (G3) is to create a healthy and full sward of species rich grassland to reinstate areas of former agricultural land disturbed by the construction and earthworks, or to create new grassland habitats on areas of land around the substation that will no longer be in agricultural use and are unsuitable for woodland planting, such as within the corridors of overhead electrical lines. The G3 seed mix is intended to assist with the introduction of grass species appropriate to the area and site conditions.
90. Details of the maintenance of the species rich grass areas are detailed in Table 6-5:
