The lands at Dowth include a broad range of habitats, from grasslands (including improved agricultural, amenity, dry and wet species-rich grasslands), native woodlands and conifer woodlands, and mature hedgerows, to freshwater swamps, reed bed and river courses. Part of the lands are designated Natura 2000 sites, including the River Boyne and River Blackwater SAC (designated for alkaline fens, alluvial forests, river lamprey, salmon and otter) and River Boyne and River Blackwater SPA (designated for kingfisher). These lands support kingfisher and some of the designated habitats. A recent biodiversity survey of the lands reported 54 species of birds, five of which are of high conservation concern, including a population of red-listed and highly threatened native Grey Partridge which is supported by a captive breeding population on site as well as Woodcock, kestrel, swifts, yellowhammer and grey wagtail. Foxes, badger, rabbits, hares, shrews and red deer have also been recorded here along with eleven species of butterfly, eight species of bat and seven species of bee. Foxes, badger, rabbits, hares, shrews and red deer are also present on the lands.
