“Think of [the list] as not so much an inventory as a catalogue leading to compelling and interacting stories.” 
Conservation designations: their borders aren’t marked by posts or buoys, but they are marked by lines on maps, and by co-ordinates and words in documents.
Native and migrant wading birds don’t know about the borders, but they know that this great seascape of changing tides and rich mudflats and saltmarshes is where they want and need to be. Burrowing crustacea, worms and bivalve molluscs, samphire, sea-kale and pink thrift, the millions of microscopic animals and plants and algae that make up the densely-interwoven life of the Solway Firth – their lives depend on the intricacy and uniqueness of their three-dimensional surroundings.
The sea and estuaries and the many types of coastal ‘edge-lands’ that form this large crooked finger of water that reaches deep into the borderlands between Scotland and England, form a ‘soup’ of acronyms. The Firth and its surrounds are protected from human exploitation and ‘re-arrangement’ by layers of statutory – that is, legally-enforceable – conservation designations. You can investigate their virtual boundaries yourself on the interactive maps on MagicMap : I have included screen-shots here (having enquired of MagicMap whether I might do so).
‘Safe areas’ along the Solway
The large, main, protected area that comprises the Upper Solway Flats and Marshes unites the two countries around the coasts and across the water. This is a Ramsar site – designated as important wetlands under The Ramsar Convention on Wetlands, an inter-governmental, ie international, treaty which ‘provides the framework for national action and international co-operation for the conservation and wise use of wetlands and their resources.’
Exactly the same area is designated under EU legislation as a European Marine Site (EMS). This is quite complicated and I quote from the Solway Firth Partnership’s website: “A Special Protection Area (SPA) is a site designated under the Birds Directive. These sites, together with Special Areas of Conservation (SACs), are called Natura sites and they are internationally important for threatened habitats and species. Natura sites form a unique network of protected areas which stretch across Europe [my italics]. The inner Solway Firth … is designated as an SAC and SPA and is collectively known as the Solway Firth European Marine Site. The [separate] Solway Firth SAC designation reflects the importance of the site’s marine and coastal habitats including merse (saltmarsh), mudflats and reefs. The Upper Solway Flats and Marshes SPA designation recognises the large bird populations that these habitats support, particularly in winter.” 
It is also a Site of Special Scientific Interest (SSSI) under UK statutory protection, overseen by Natural England & Nature Scot, respectively. So this multi-layered protected space is not trivial.
And note that a proposal to extend the SPA is still under consideration (the decision has of course been delayed, due to the Covid19 outbreak and Brexit negotiations – we might finally hear this summer, 2020).
Although not strictly within the Firth, there are other international Ramsar sites along the adjacent coasts: the inner part of Luce Bay, and the Duddon and Morecambe Estuaries (again, on the basis of being internationally important wetland areas). They – and the coast at Drigg near Sellafield – are also Special Areas of Conservation, SACs, under EU statutes.
(The Solway’s importance for birds – so many species, both residents and migrants, and in such numbers – is also recognised by the UK charities the Wildlife & Wetlands Trust with their big wetland and coastal reserve at Caerlaverock, and by the RSPB’s coastal and wetland reserves at Campfield and St Bees’ Head.)
Over the past few years, DEFRA has designated parts of the English and Irish seas and coast as Marine Conservation Zones (MCZs). The Cumbrian Coast MCZ stretches along the shore from St Bees’ Head to Ravenglass, and Allonby Bay MCZ pushes out into the Solway, recognised especially for its important honeycomb-worm (Sabellaria) reefs. The Solway Firth MCZ around Rockcliffe Marsh and the mouth of the R Eden is mainly for the protection of sparling (smelt, or cucumber fish) as they migrate upstream to spawn.
MCZs are designated under the UK’s Marine & Coastal Access Act, which in turn was set up in response to the European Marine Strategy Framework Directive.
Parcels of protection
The sea, estuaries, mudflats and saltmarshes of the Solway Firth have been parcelled, here and there, into places of protection for our ‘natural capital’ – which, in reality, means the vast numbers and species of other residents of our own land- and sea-scape.
But the Solway’s estuaries and coasts are not solely a product of the sea and the mouths of the many rivers that flow into the Firth because they are also influenced strongly, both in geological time and the short-term, by what happens inland.
If we move inshore, a little deeper into the edgelands, we find dunes, then peaty raised mires (the ‘Mosses’) and areas of carr and wetland where water is retained. Many of these places are special, too, for their appearance and ‘feel’, the colours, the smells, and the very different plants and animals and fungi that live there. And luckily for us – and them – many are under statutory protection.
Most of the UK’s remaining raised mires are around the Solway’s upper end, and the three South Solway Mosses – Wedholme Flow, Glasson Moss, Bowness Common – plus Drumburgh Moss, on the English side, are Special Areas of Conservation (SACs) protected by European legislation . So too is Kirkconnell Flow near Dumfries.
Then there are the National Nature Reserves (NNR), protected by UK legislation: on the English side, the South Solway Mosses, Drumburgh Moss, Walton Moss and Thornhill Moss; on the Scottish side Caerlaverock and Kirkconnell Flow.
We have the Solway Coast Area of Outstanding Natural Beauty, the AONB, 50 km of coastline stretching from Maryport along the dunes and saltmarshes to Rockcliffe, managed in statutory compliance  with the Countryside & Rights of Way Act 2000 (CroW) and overseen by the three local councils, and Natural England; the AONB incorporates SSSIs too.
And there are many SSSIs, both sides of the Firth, along the coast and inshore; they too are under UK statutory protection through the Wildlife & Countryside Act 1981 and CRoW, and managed by Natural England and Nature Scot. Amongst them, I’ve already mentioned the Upper Solway Flats & Marches – but there are also, for example, the SSSIs of the South Solway Mosses, Finglandrigg Wood, Silloth Dunes and Mawbray Banks, Maryport Harbour, St Bees’ Head, Drigg Coast … and on the Scottish side, Kirkconnell Flow, Auchencairn and Orchardtown Bays, Abbeyhead Coast, Brighouse Bay, Wigtown Sands and the Whithorn Coast…
I haven’t yet mentioned the many GeoConservation Sites (formerly known as RIGS), such as exposures of the submerged forest near Beckfoot, and Birkham’s red sandstone quarry above St Bees’; although some of these are SSSIs and therefore under statutory protection, many are not. And I’m not going to consider the few Local Nature Reserves such as Siddick Pond.
‘Too much information?’
I’ve gathered this information here
firstly to understand how, and to what degree, the Solway Firth and its edgelands are protected from human intervention, whether from carelessness or from major construction projects;
and secondly, to try to dispel my own despair over lists of acronyms by considering what these ‘designated areas’ mean in real-life terms.
Let’s turn again to Richard Fortey: “Think of [the list] as not so much an inventory as a catalogue leading to compelling and interacting stories.” He persuades us to think beyond the check-list of ‘species found’: to pause, and take time to examine the life-habits of those species.
But his suggestion could equally apply to the list of designated conservation areas along the Solway. SAC? Tick. SPA? Tick. SSSI? Tick, tick, tick … What is the reality of these places on the ground?
Some of these ‘acronyms’ stories’ are elsewhere on this blog.
But what if their story-book gets torn, or if a group of people decide the books are merely clutter and should be thrown out?
If you carry out dredging operations on Ramsar mudflats, place gas-gun bird-scarers on an SAC, drag a trawl across the bottom of an MCZ, or set fire to the heather on a SSSI – who has the power to stop you? Will you get a ‘talking-to’ or be taken to court? And if you are to be prosecuted, under which laws, and in which court and where – a local magistrate’s court, a Crown court… The European Court of Justice will soon have no powers of legislation in the UK. At the time of writing this, we’re waiting on the progress of the new Environment Bill which makes provision for a UK Environmental Court.
The answers to any questions regarding legislation are, as you might expect, very complicated (and might lead you on to further questions such as ‘So, who does own the foreshore of the SAC?’ – and the answer to that depends on which foreshore …).
It also depends whether the damage is done by you, as an individual and therefore ‘third party’ (when you might be answerable to, for example, Natural England  and petty crimes might be prosecuted in local courts), or whether the damage occurs because one of the statutory organisations – such as the Marine Management Organisation (MMO), Natural England, Nature Scot – have failed to fully protect or manage a designated site. More serious infringements could well require lawyers expensively well-versed in international environmental law.
After looking into this, and asking questions of my friends and contacts in the relevant organisations, I realised this section could stretch to several pages. So, happily, I can point you to the Marine section of the excellent website , ‘Law & the environment, a plain guide to environmental law’
Also, there is a government website solely concerned with legislation. From the page on Marine Strategy regulations you can, if you wish, click on Section 2, Enactments, and can keep following and clicking (here, for example, is how the MMO has power to bring legal proceedings). And so on, and on, until you forget which question you wanted answered, and need to escape to watch videos of ‘dogs doing silly things’ on YouTube.
Instead, it’s often worthwhile to pause and try to imagine what those acronyms stand for in the real world of the Solway Firth and its edgelands – and feel positive about the future.
