Situated in south-west Scotland, the Silver Flowe-Merrick Kells biosphere reserve is composed of two separate sites.

Contents

Silver Flowe is a unique bog formation and one of the least interrupted undisturbed mire systems in Europe. Its high value is principally due to the landscape pattern of an assemblage of discrete mires. It is also a breeding site for the rare Azure Hawker dragonfly. Silver Flowe is also designated as Ramsar site.

Silver Flowe Protected area of peatland in southern Scotland

Silver Flowe is an area of patterned blanket mire in the Galloway Hills, in Dumfries and Galloway, Scotland. Located around 16km north northeast of Newton Stewart, it forms part of the Galloway Forest Park. An area of 620 hectares has been designated as a Ramsar Site.

Bog wetland that accumulates peat due to incomplete decomposition of plant leftovers

A bog or bogland is a wetland that accumulates peat, a deposit of dead plant material—often mosses, and in a majority of cases, sphagnum moss. It is one of the four main types of wetlands. Other names for bogs include mire, quagmire, and muskeg; alkaline mires are called fens. They are frequently covered in ericaceous shrubs rooted in the sphagnum moss and peat. The gradual accumulation of decayed plant material in a bog functions as a carbon sink.

Mire wetland terrain without forest cover, dominated by living, peat-forming plants

A mire is a wetland type, dominated by living, peat-forming plants. Mires arise because of incomplete decomposition of organic matter, usually litter from vegetation, due to water-logging and subsequent anoxia. All types of mires share the common characteristic of being saturated with water at least seasonally with actively forming peat, while having its own set of vegetation and organisms. Like coral reefs, mires are unusual landforms in that they derive mostly from biological rather than physical processes, and can take on characteristic shapes and surface patterning.

Merrick Kells contains three habitats of European interest: blanket bog, montane acid grasslands, and wet heath with cross-leaved heath. There are mires supporting various communities, and the area has a wide variety of species but low population levels. There are nationally important breeding bird populations, and important invertebrate populations. The site is the largest remaining unafforested area of upland in Galloway.

Blanket bog

Blanket bog or blanket mire, also known as featherbed bog, is an area of peatland, forming where there is a climate of high rainfall and a low level of evapotranspiration, allowing peat to develop not only in wet hollows but over large expanses of undulating ground. The blanketing of the ground with a variable depth of peat gives the habitat type its name. Blanket bogs are found extensively throughout the northern hemisphere - well-studied examples are found in Ireland and Britain, but vast areas of the Russian and North American tundra also qualify as blanket bogs.

Heath shrubland habitat

A heath is a shrubland habitat found mainly on free-draining infertile, acidic soils and is characterised by open, low-growing woody vegetation. Moorland is generally related to high-ground heaths with—especially in Great Britain—a cooler and damper climate.

Invertebrate Animals without a vertebrate column

Invertebrates are animals that neither possess nor develop a vertebral column, derived from the notochord. This includes all animals apart from the subphylum Vertebrata. Familiar examples of invertebrates include arthropods, mollusks, annelids, and cnidarians.

Both sites are surrounded by commercial coniferous forestry. The management of Merrick Kells and Silver Flowe is mainly carried out through non-intervention, apart from areas where extensive livestock grazing is practised in order to manage vegetation.

Proposals made in the periodic review for extending this reserve to meet the Seville criteria are being considered.

Major habitats & land cover types

The mire is dominated by Trichophoreto-Eriophoretum including Sphagnum plumulosum , Drosera anglica , Pleurozia purpurea and Campylopus atrovirens ; submontane vegetation including Molinietum and damp Callunetum ; rocks with grassy cover supporting Nardus spp. and Juncus squarrosus.

<i>Drosera anglica</i> species of plant

Drosera anglica, commonly known as the English sundew or great sundew, is a carnivorous plant species belonging to the sundew family Droseraceae. It is a temperate species with a generally circumboreal range, although it does occur as far south as Japan, southern Europe, and the island of Kauaʻi in Hawaiʻi, where it grows as a subtropical sundew. It is thought to originate from an amphidiploid hybrid of D. rotundifolia and D. linearis, meaning that a sterile hybrid between these two species doubled its chromosomes to produce fertile progeny which stabilized into the current D. anglica.

Cairnsmore of Fleet is a mountain in the Scottish Lowlands, on the edge of the Galloway Forest Park. The mountain forms an unafforested granite massif, whose highest point is about 10 kilometres (6.2 mi) east of Newton Stewart. It is the highest of the "Solway Hills", and the southernmost of Scotland's 219 Grahams. The view to the south takes in the Cree Estuary and Wigtown Bay, and extends as far as the Lake District, the Isle of Man and Snowdonia. The highest summits of the Galloway Hills can be seen to the north, and Ireland is in the view to the west.

The two lochs are separated from Loch Valley and Loch Naroch to the north by the Rig of the Jarkness.
