such as the restoration of traditional farm buildings. All Higher Level Stewardship (HLS) agreements must be underpinned with basic management from an ELS or OELS agreement, but in contrast to these schemes the agreement lasts 10 years. All agreements start at one of four start dates at three-monthly intervals through the year. The first HLS agreements started on 1 February 2006. There was a delay in the launch of HLS as a result of problems with the department's computer system, "Genesis", built by Atos Origin. The application procedure is basically the same as for ELS but, due to the added complexity and competitiveness of the scheme and its highly targeted nature, a visit from a Natural England advisor is required. The payment received for HLS agreements is dependent on the precise options chosen, rather than a flat rate. Upland Entry Level Stewardship Is a new scheme following the same format as the entry level stewardship schemes. It was launched in 2010, with the first agreements running from 1 July 2010. It replaced the 'Hill Farm Allowance Scheme', a DEFRA and RPA run scheme. Management options covered by the ELS, OELS, HLS and UELS schemes Hedgerow maintenance options. Important for wildlife as shelter and a food source for animals, for example small birds, dormice. A historic and cultural landscape feature, acting as a barrier to livestock. Hedgerows can also act as pollinators for orchard trees, the nectar and pollen also being of benefit to invertebrates such as bees. The management options encourage the practice of trimming the hedgerows less frequently, to allow them to grow, thicken, and bear fruit. There are other requirements such as not trimming during the bird breeding season so that the nesting birds are not disturbed, and not applying fertiliser or pesticides within 2 metres of them, to encourage wildlife biodiversity. The growth and protection of hedgerow trees is also encouraged under these options. Dry stone walling maintenance options. Important for similar reasons to hedgerows, including habitat for lichen, mosses and ferns. In field trees. Important habitat for animals, lichen etc. Even if the tree is dead it can offer habitat for birds and bats. Management options include not cultivating under the canopy of the tree, which helps to protect its roots. Woodland. Options to encourage structural diversity within and at the edges as many wildlife cannot tolerate a simple structure. Also options to let light into
