Bog at Close Sartfield

Bog, meadow and curragh at Close Sartfield

At Close Sartfield, areas that people may think of as “bog” are part of a wider wetland landscape shaped by water, peat and seasonally wet soils. Around the bird hide and across parts of the reserve, humid grassland merges into wetter curragh habitat, creating conditions that support a rich variety of plants, insects and birds.

These wet grasslands are very different from improved farmland. Waterlogged, peaty soils limit vigorous grasses and allow moisture-loving wildflowers, sedges and rushes to thrive. Wet conditions also create shelter and feeding habitat for insects and spiders, including wolf spiders hunting amongst low vegetation and mossy ground.

At MWT Close Sartfield Reserve, the bird hide looks out across this wetland mosaic. Wet grassland and boggy ground can support high numbers of insects and other invertebrates, attracting birds to feed and shelter. A hide also allows people to quietly experience the wetland without disturbing wildlife as easily in this open landscape, where birds can quickly spot movement.

Close Sartfield lies within the Ballaugh Curraghs, the Isle of Man’s largest wetland system. The reserve is both an ASSI (Area of Special Scientific Interest) and part of the Ballaugh Curraghs Ramsar Site, recognising its national and international importance for wildlife and wetland habitats.

A Ramsar Site is a wetland recognised under an international convention for its importance to nature and biodiversity. ASSI designation helps protect areas of special scientific and ecological value.

MWT Close Sartfield is not comprised of one single habitat, but a connected mosaic of orchid meadows, wet grassland, boggy ground, willow curragh woodland, pools and peat-forming wetlands. Water links these habitats together. Seasonal flooding, high water tables and peaty soils shape the plants that can grow here, which in turn support wider food webs of insects, birds, bats and fungi.

At Close Sartfield, MWT manages the reserve through traditional hay cutting, grazing and willow coppicing. Meadows are cut after flowers have set seed, helping maintain the diversity of orchids and wildflowers. Coppicing willow creates a changing pattern of light and shade within the curragh, supporting different species at different stages of growth.
