Carabus clathratus, rare beetle typical of peat bogs.
The National Park is managed by the National Parks and Wildlife Service (NPWS), part of the Department of Arts, Heritage and Gaeltacht, and encompasses approx 14,000 ha, including a recent consolidation of lands to the east of the Nephin Beg mountain range, which previously had been managed by Coillte Teoranta (Coillte) for commercial forestry. These lands, like many of the peatlands in Ireland, were viewed as ‘marginal’ lands in the 1950s and 1960s and of little economic use – so they were drained, modified and planted to create the monoculture of Sitka spruce and lodgepole pine that now dominates the landscape. These uplands have also been characterised by decades of overgrazing by sheep – a consequence of the broken subsidised system of the European Agricultural Policy in the 1980s and 1990s. This led to serious overgrazing in the hills, with soil erosion, siltation of the rivers and loss of biodiversity.
The Nephin forest plantation is approx 4,000 ha and fringes the entire eastern section of the National Park up to an altitude of 250m on the eastern slopes of the Nephin Beg mountain range. NPWS acquired these lands with the specific intention to rewild and to allow natural processes to become the dominant driver in shaping this highly modified landscape – where biodiversity is enhanced, functioning ecosystems restored and people have the freedom to engage with nature. A place where the visitor can experience solitude and reconnect with nature. We intend for this area to be the ‘honey pot’ for the National Park, where visitors will have an opportunity to explore the rewilded landscape along a network of trails. From here the visitor can venture further into the heart of the National Park along the Bangor Trail, where there are opportunities for primitive and challenging recreation in a wild and remote landscape, free from mobile phone coverage, free of houses and roads, free from the noise of a busy world. A place where time passes slowly.
The National Park lands are divided into primitive, semi-primitive and semi-developed natural zones. These zones will guide us on how to manage recreational access, with the overarching theme of a minimal tool approach. The National Park is also designated as a Dark Sky Park, a designation from the International Dark Sky Association. We have committed to maintaining our pristine, unpolluted skies from light pollution.
The rewilding project is ambitious for such a large, highly modified area – and with no budget secured yet for conservation initiatives, or extra staff, the challenges can seem overwhelming when you look at the project in its entirety. The invasive Rhododendron ponticuum is a notable concern, with significant mature stands in the south of the site – with the prevailing strong westerly winds, the seeds spread with vigour and wild abandon.
The first major step, though, has been to set out the vision for the rewilding project. A ‘Conversion Plan’ was completed in 2018 setting out a strategy for the next 15 years, the vision to move from a commercial forestry plantation to a place where the conditions have been prepared for nature to become the dominant force. Specific measures have been identified for forested and non-forested areas, as well as riparian and aquatic zones. Blocking drains and bog restoration is essential to mitigate against flooding, improve water quality, and enhance linkages and wildlife corridors.
Felling of conifers over the next five years will be significant, with the purpose of creating an open and diverse forest with improved connectivity between bog, mountain, lakes and rivers. Habitat conditions throughout much of the plantation are currently not suitable for native woodland, so the vision is to develop low-density forest which will allow old growth. Broadleaf cover with native tree species will be promoted on suitable soils, as well as introduced tree species of high ecological value (Monterey pine). We will focus planting of native trees along riparian zones and where soils are drier.
We have already started planting small trial plots of trees (aspen, Scots pine, birch and rowan) to monitor success rate in various site conditions. There are significant pressures from grazing animals (deer and sheep), but we have planted aspen on steep ground to avoid browsing animals. The aspen has been propagated from various locations in the west. We hope to have tree-planting events where local community groups, volunteer groups and schools can come and get involved in the rewilding process.
Deer management as well as rhododendron clearance and control will be essential to allow native trees to establish. The concept of long-term management may be at odds with the overall principle of rewilding, where nature is the dominant force. Without natural predators, though, these two invasive species become the overall dominant force and hinder the natural processes – so it is likely that management of deer and rhododendron will need to continue into the future. Many rewilding projects include the introduction of top predators or large mammals – beaver, crane, black grouse, wolf, lynx – to create a trophic cascade that will balance the ecosystem. It is indeed visionary to try and establish the trophic levels that would have existed here during the postglacial period. Is this a feasible option, though, in Wild Nephin National Park? The state, as landowner, cannot rewild this area without the enthusiasm and support of the local communities. We want to maximise benefits for people as well as the environment. Benefits in terms of environmental services, opportunities to grow ecotourism and ‘cottage industry’ initiatives.
Ballycroy National Park.
The National Park should not be a separate place to the local community; it needs to be part of the community. This landscape has been influenced by humans since the Neolithic period. Ancient human remains, discovered by a local hillwalker in a natural boulder chamber in Ben Gorm (part of the Nephin range) in 2016, date back to 3,600 bce. Research suggests that this site was used as a burial chamber for over 1,000 years. The large ring fort, Lios na Gaoithe (Fort of the Wind), in the northeast of the rewilding site, would have been sited at a strategic location (500–1000 ce) with clear views south and north along the river valley. These views were lost as the conifers grew – but with time and sensitive management this important fort can become part of the wild landscape again, reconnecting the past to the present.
The possibilities are endless, our ambitions and vision are evolving all the time – but with initial small steps and with many steps together, we hope that this place, Wild Nephin National Park, will become an integral part of the community, allowing connection to our past, present and a wild future. A place where peace is found and nature is protected.
Large heath butterfly.
Hundreds of birds create shadows across the landscape. It’s winter. Curlew, lapwing, whooper swan and a range of other birdlife have flocked to the Lough Boora Discovery Park, in the heart of Ireland, to make use of the wide range of habitats that spread across over 3,000 ha of this Irish Midlands refuge.
The Boora Bogs have been central to many changes over the course of their history. Up until the early 1900s most of this area of middle Ireland was a rich tapestry of sphagnum-dominated raised bogs, with associated streams, bog woodland, flushes and the odd human settlement in between. A tranquil place, with little or no industry. But those deep and wet bogs were to become the source of the highly-valued peat that fed the Ferbane power station in County Offaly, and the domestic fire places of families across Ireland. To mine the resource, the great bogs were taken on by Bord na Móna (the Irish Turf Board) in the 1930s, working with the local communities who were forging a living in an otherwise bleak time, for the nascent Irish Republic. And so, the wild bog became industrial bog, and СКАЧАТЬ
