Dartmoor is home to a vast array of rare and fascinating plants, from ancient oak woodlands to creeping heather and bilberry, but some of its tiniest plants might be the most fascinating of all. Bryophytes are non flowering plants which include hornworts, liverworts and mosses, that have adapted to thrive in a broad range of environments. Although they can be found almost everywhere, from lawns to sand dunes, they do particularly well in Devon’s mild and wet climate, with around two thirds of the 1,100 UK species of bryophytes present in the county.
Despite being small, these plants play an important role within Dartmoor’s environment. They hold water after rainfall, absorb carbon and help in the creation of peat bogs, which in turn offer vital habitat for microorganisms and other specialist plants. Being sensitive to air and water pollution, they’re also an indicator of a healthy environment, with a diverse selection of healthy bryophytes suggesting that the surrounding habitat is in good condition.
Key habitats for bryophytes include acidic peat bogs, mires and temperate rainforests, all of which can be found on Dartmoor. On DPA owned land at High House Waste we have a mosaic of these types of habitat and we’re working with our Ecologist, Albert Knott, to preserve and enhance biodiversity. Gaining a clear understanding of the type and spread of bryophytes we have present helps us to make decisions about land management, including in our humid Atlantic oak woodland, which provides ideal conditions for scarce oceanic bryophytes.
On the 16th of October Devon Bryophyte Group joined local DNPA ranger, the Natural England Senior Reserve Manager and Albert Knott for a visit to High House Waste and adjacent land in the river catchment. One of the aims was to visit the upper reaches of the Broadall Lake stream, which were not part of Sharon Pilkington’s earlier visit. The group were impressed by the presence, or interest, of bryophytes on willow dominated reaches. They also identified areas where possible management could be carried out, without affecting the interest.
