Introduction
Together with the adjacent Seaforth Docks complex (now Liverpool Free Port), Crosby Coastal Park was reclaimed from the Mersey Estuary in the late 1960s. The section studied here extends south from Crosby Baths to the Freeport fence (Fig. 1). It has an elongated triangular shape about 1.6km long with a maximum width of 0.8km at its southern end; a central National Grid Reference is SJ314980. The study site has an area of about 54ha, of which 26ha is occupied by a large Marine Lake, while a much smaller (1.4ha) boating lake lies to its north. A concrete promenade bounds the western edge of the site, beyond which lies a broad beach providing a source of wind-blown sand for dune ridges 30-80m wide that extend roughly north-south on either side of the promenade. These have formed since reclamation and represent the southernmost sand-dunes on the Sefton Coast. The northern section of the eastern ridge was largely removed in 2011 to provide 30,000 tonnes of sand for a coastal defence scheme at Hightown. There are two large fixed dunes north of the boating lake, these having been created artificially during the construction of a pumping station in 1995/96. Most of the rest of the site consists of sandy grassland, some areas being waterlogged in winter. A large proportion is regularly mowed and used for informal recreation by many visitors, some of whom are attracted by the Another Place art-work by Antony Gormley, consisting of 100 cast-iron statues on the adjacent shore. In the south-east corner of the Marine Lake is a small (2ha) nature reserve created in the early 1990s, consisting of marshy grassland surrounded by wet-woodland with two shallow excavated ponds. A nature trail on about 400 m of trackway was established here in 2016.
Designations
The Park and nearby intertidal zone has long been recognised for its wildlife interest. The foreshore and dune ridge west of the promenade lie within the Sefton Coast Site of Special Scientific Interest (SSSI). This is also a Special Area of Conservation (SAC) under the EU Habitats Directive and a Special Protection Area (SPA) under the EU Birds Directive. SACs and SPAs together form the Natura 2000 network of protected nature sites across Europe. The foreshore is also part of the Ribble and Alt Estuaries Ramsar Site, a wetland of international importance. The Park, including the dunes east of the promenade, is not statutorily protected but the 400ha Crosby Marine Lake, Park and Shore was designated in 2001 as a Site of Local Biological Interest, now a Local Wildlife Site under the Sefton Local Plan. The citation describes relict sand-dune habitats with a coastal lagoon, forming part of the coastal corridor for over-wintering and passage bird populations. Botanical interest was represented by an inventory of 170 plant species, of which one was Nationally Rare, one Nationally Scarce, nine regionally important and 10 locally rare.

Botanical surveys
Many reports and published articles have been written on the botany of the Coastal Park, these being summarised below. Other records have been obtained from data submitted to the vice-county vascular plant recorder since 2004, together with casual observations. Nomenclature follows Stace (2010) and subsequent amendments.
Edmondson et al. (1988) studied the Park in 1988 as part of their comprehensive UK National Vegetation Classification (NVC) survey of the Sefton Coast but, unfortunately, did not include a species list. They found that little natural vegetation survived between the recently constructed sea-wall and residential areas but described new dunes forming in places to the west of the promenade and “climbing over” the sea-wall into the open space beyond. The outer dune ridge was mapped at about 450m long. Both ridges supported SD4: Elytrigia juncea foredune and SD5: Leymus arenarius mobile dune communities. Most of the open space was managed as short-mown amenity grassland, its vegetation being mapped as MG7: Lolium perenne ley, a seeded sward which they describe as “botanically uninteresting”. Some Red Fescue swards were found around the Marine Lake, having affinities with both MG7 and SD8: Festuca rubra-Galium verum fixed-dune. The area immediately south of Crosby Baths consisted of a mosaic of bare sand with SD4 and SD5 communities. Only small areas of scrub were found, comprising a few stands of Sea Buckthorn (SD18), Japanese Rose and Tree Lupin (for scientific names of species see Appendices).
A follow-up NVC survey of the Park was carried out seven years later by Edmondson (1995), again without a species list. She found that the conservation value of the amenity grassland had increased by the greater occurrence of sand-dune and maritime species, such as Bird’s-foot-trefoil, Red Fescue and Buck’s-horn Plantain, a particular feature being the spectacular flowering of Dandelion in spring. The dune ridges had increased in height and length, the outer ridge now being 750m long. The effect of trampling on dune vegetation was noted, though apart from a few pressure points there seemed little threat of erosion. However, there was a potential for blown sand to impact adjacent housing. Sea Holly appeared to have increased since 1988 but Edmondson did not find Isle of Man Cabbage, despite the fact that it had been introduced in 1992 during a conservation exercise (see below). A variety of wetland communities was recorded in the fenced-off nature reserve by the south-east corner of the Marine Lake. Garden waste dumping was noted as a cause of eutrophication and a source of non-native plants. Target notes listed introduced species associated with the interface between housing and the Park grassland, eighteen of these not found during later surveys being tabulated in Appendix 5. Another negative factor was heavy use of the Park by dog-walkers, leading to fouling near carparks and access points. She recommended relaxing the mowing regime in places to allow structural diversity and a wider range of species. A further suggestion was the introduction of native plants, though many of those listed have subsequently appeared by natural colonisation.
A third NVC survey of the Coastal Park took place in 2004 (Gateley & Michell 2004). By this time, coastal dynamism was affecting the managed swards. Thus, south of Crosby Baths, sand-blow had created a line of SD5 and SD6 dunes that had continued to grow, widen and mature. East of the mobile dune ridge, Gateley & Michell mapped an SD8 fixed-dune community, giving way to amenity grassland further south. In 2004, almost constant use of a tractor was needed to clear blown sand from the promenade. The area around the Marine Lake and boating lake had a run-down appearance with little diversity of sand-dune communities. However, the nature reserve now supported a range of orchid species, while drifts of marsh-orchids also occurred along the western edge of the Lake. The latter were lost when a footpath was constructed around the Lake in 2005. Areas of scrub had increased, with Sea Buckthorn, in particular, prolific to the west and south of the Lake.
Smith (2005) conducted a detailed botanical survey of the dune ridges and adjacent dune grassland in spring and summer 2005, identifying all the vascular plants and recording their relative abundance (Appendix 1). He also noted topography, land-use and habitat condition. Most of his study area consisted of undulating mobile (yellow) dunes dominated by Lyme-grass, Marram and Sand Couch. There was a local abundance of Sea Holly and Sea Spurge. The back-slope of the eastern ridge, with a gradient of 30 – 45o, consisted of semi-fixed dunes with a high plant species-richness. Similar vegetation occurred on an area of low, undulating semi-fixed dunes which extended for about 400m south from Crosby Baths. This habitat was maintained by moderate trampling, Rabbit-grazing and a rain of blown sand from the mobile dunes and foreshore. Frequent sandy footpaths ran east-west through the eastern dune ridge but blow-out development was quite limited, indicating that public pressure was not excessive at that time, as noted earlier by Edmondson (1995).
The more recently formed ridge on the foreshore west of the promenade was steep-sided, susceptible to trampling damage and quite unstable with vegetation (mainly Lyme-grass) largely confined to the crest. Typical fixed (grey) dune vegetation was largely restricted to two reprofiled mounds north and south of the pumping station. The southernmost section of the eastern dune ridge, from the Marina sluice to the Free-port boundary, had also been reprofiled in the past to produce a plateau-like area of heavily Rabbit-grazed semi-fixed dunes with patches of Marram. North of the sluice were several large clumps of Sea Buckthorn.
Smith’s (2005) survey identified a total of 141 vascular plants (Appendix 1). Only 31 (22%) of these were non-native or introduced native taxa. Nine regionally or nationally notable plants were found. The Nationally Rare Dune Wormwood occurred as a single flourishing specimen just south of the pumping station (Fig. 2). Discovered in 2004, it was thought new to Britain (Smith & Wilcox 2006) until a second site in South Wales was reported (Twibell 2007). Both Twibell (2007) and Clement (2006) argued that this sub-species was native in Britain, having been overlooked or previously recorded as “alien”. The Crosby plant was subsequently joined by three smaller individuals that had evidently grown from seed (Smith 2008; 2010a). Prof. Joan Vallés-Xirau of Barcelona University made a visit to see this small population in September 2008, collecting (with permission) some samples for his genetics research. He wrote to Sefton’s Coast & Countryside Service (Vallés-Xirau in litt. 2008) detailing the botanical interest and condition of this dune area and emphasising the importance of its future conservation. In 2015, the Millennium Seed Bank at Kew requested a sample of seed from this population.
Also present in Smith’s study area was the Isle of Man Cabbage, a Nationally Scarce British endemic largely confined to Northwest England coasts. The Crosby colony on the central section of the inner dune ridge originated as a translocation in 1992 from a relict population about to be destroyed by development at Blundellsands (Smith 2007). It was monitored regularly and increased to about 650 plants in 2011. In the latter year, the dunes occupied by the Isle of Man Cabbage were removed for the Hightown coast protection scheme mentioned earlier (Fig. 3). Before works commenced, volunteers transplanted many small rosettes to the outer dune ridge in a rescue operation. During the 2011/12 winter, large quantities of sand from the extracted inner ridge were blown across the Park (Fig. 4). Despite heavy human trampling the remnants of the ridge slowly and partially re-vegetated over the next few years. An unexpected event was the appearance of large numbers of Isle of Man Cabbage plants, presumably from long-buried seed. By 2015, these totalled 1361 individuals, perhaps the largest population in Britain (Smith & Lockwood in press) (Fig. 5). The translocated colony on the outer ridge also increased, reaching 211 plants by 2015 (Smith & Lockwood in press). The disturbed ground of the inner ridge was also re-colonised by large populations of Sea Holly and Sea Spurge, both being regionally notable species. The Nationally Rare coastal form of Groundsel and the uncommon coastal grass, Rush-leaved Fescue, also appeared.

Smith (2012) conducted a botanical survey of the 2ha nature reserve in the south-east corner of the Marine Lake. Several major vegetation types were identified as follows:
- Wet woodland dominated by Alder up to 10m tall, with occasional Broad-leaved Osier, Grey Willow and Goat Willow, etc.
- Marshy grassland with Red Fescue, Creeping Bent, Yorkshire-fog, Creeping Buttercup, False Fox-sedge and several rush species. Southern Marsh-orchids occurred sporadically and some areas supported Marsh Helleborines. The eastern fringe was being invaded by dense Sea Buckthorn and scattered Alder
- Tall-herb communities on spoil excavated from the scrapes and ponds, comprising Great Willowherb and Reed Canary-grass, together with patches of Creeping Thistle, Dotted Loosestrife, Michaelmas-daisy, Japanese Rose, etc.
- Brackish-water communities on the lake fringe characterised by dense stands of Sea Club-rush with patches of Sea Milkwort, while transition zones with the marshy grassland supported much Parsley Water-dropwort.
- Ponds with spreading marginal vegetation consisting of Bulrush, with Sea Cub-rush, Soft Rush and Tufted Forget-me-not, etc.
A total of 101 vascular plants was identified (Appendix 2), plus eight additional taxa recorded during visits in 2004/05. Most of the plants recorded are common in Sefton, only six being listed as regionally or nationally notable. Nevertheless, this was quite high biodiversity for such a small area. Of particular interest was the presence of four orchid species and several indicators of brackish-water conditions, such as Parsley Water-dropwort which is quite localised on the Sefton Coast.
Smith & Lockwood (2010) studied the frontal dune ridge west of the promenade in 2010. The developing ridge was estimated to be 800m long, up to 30m wide and covered about 2.2ha. Only 30 vascular plants were recorded, two being regionally notable (Appendix 3). Where present, the vegetation was dominated by the dune-forming grasses, Sand Couch, Marram and Lyme-grass, the back-slope of the central region being a little more sheltered and stable with a wider range of species. An incipient strandline along the dune frontage consisted largely of scattered Sea Rocket. The ridge was subject to heavy and uncontrolled informal recreation, leading to loss of vegetation, severe wind-erosion and the deposition of large amounts of sand on the adjacent promenade. This required frequent mechanical clearance and had broken down the promenade railings in several places (Fig. 6).

Most recently, Smith et al. (in press) reported the discovery of Sea Couch in July 2016 on dunes to the west of Crosby baths (Fig. 7). This coastal grass was thought extinct in South Lancashire, Crosby being perhaps the only locality in Northwest England north of the Dee Estuary. Its hybrid with Sand Couch was already known from the southern part of the Park.
Casual observations in recent years have revealed other interesting native plant species in the Park including, in some years, dozens of Bee Orchids, especially on the lower parts of the two fixed dune mounds. Here, is also a large population of Rough Hawkbit, otherwise rare on the Sefton Coast. A marshy area adjacent to the boating lake supports important concentrations of Slender Spike-rush (Smith 2010b) and Southern Marsh-orchid, while the boating lake itself has dense growths of Fennel-leaved Pondweed (Appendix 5).

Non-native plants
Crosby Coastal Park has long been renowned for a wide variety of non-native plants, many having their only location on the Sefton Coast. At least 133 taxa have been listed since 2004 (Appendix 4), new ones being identified almost every year. Edmondson (1995) recorded an additional 18 taxa not seen subsequently. A high proportion of these plants originate from adjacent gardens and from the dumping of garden waste along the eastern boundary of the site. A few are of transient occurrence, though many have persisted for a decade or more. Of particular interest is the presence of at least five taxa of Evening-primrose (Oenothera). Originating mainly from North America in the 19th century, these include the rare hybrid O. ×britannicum (Large-flowered × Small-flowered Evening-primrose). First seen in 2005, it was not identified until July 2016 when specimens were submitted to the national expert on this group, Rosemary Murphy. This striking plant (Fig. 8) is known from only about eight hectads in Britain (BSBI maps).

Fig. 9. Triplet Lily near Crosby Baths, June 2016
One of the garden escapes, the attractive Triplet Lily, is particularly rare nationally (Smith & Wilcox 2006), having been recorded in the wild at only one other locality. It was first noted in 2004 and was still present twelve years later (Fig. 9). It is important to note here that only two non-native species, Sea Buckthorn and Japanese Rose, have become invasive and problematic in the Park area.
Assessment
Crosby Coastal Park supports a remarkably high diversity of vascular plants. The Appendices list 200 native taxa, together with 159 non-native plants, making a grand total of 359 (44% alien). This is more than twice the number of plants mentioned in the LWS citation. However, it is likely that several species were missed as few visits were made in spring and common plants were not always recorded. Although the proportion of non-native taxa seems high, this is comparable to the 40% figure for the coastal zone as a whole (Smith 2015). Twenty-two (11%) of the natives are regionally or nationally notable (Table 1). This is a much smaller proportion than the 28% for the entire Sefton Coast (Smith 2015), probably because of the paucity of dune-slack vegetation which supports many notable species coastwide.
All coastal sand-dune habitats are listed on Annex 1 of the EU Habitats Directive, with fixed (grey) dunes afforded Priority Status. While much of the Sefton Coast sand-dune system is presently considered to be in unfavourable or unfavourable-recovering condition, the Crosby dunes probably qualify for favourable condition status, due to their immaturity, relative mobility, lack of scrub and high plant species-richness. Nevertheless, both dune ridges have been severely damaged by sand-extraction and uncontrolled recreational pressure, leading to sand-blow inland and the formation of blow-outs. However, the open nature of the habitat creates opportunities for a range of pioneer species, including the British endemic Isle of Man Cabbage, for which this is probably now the best site in the country (and therefore in the world). The Park is also nationally important as one of only two British localities for Dune Wormwood.
Although a high proportion of the Park’s area is amenity grassland, this has become markedly more species-rich over the last few decades, this increased diversity being assisted by relaxation of mowing frequency in some areas (Fig. 10). The wetland habitats associated with the boating lake and the nature reserve also contribute a wide range of additional plants, including several notable species.

Conservation management
Much of the Park grassland is managed by regular mowing for recreational purposes, which restricts the variety of plantlife. However, as previously noted, the mowing regime has been relaxed in some areas in recent years, resulting in more varied vegetation (Fig. 9). About 0.4ha of sandy dune grassland 150m south of Crosby Baths was fenced off about a decade ago, leading to a diverse open sward with Evening-primroses and other duneland flora.
Sea Buckthorn and Japanese Rose scrub seem to be increasing and control of these invasive species, as elsewhere along the coast, is justified. The recently discovered population of Sea Couch near Crosby Baths is directly threatened by a spreading canopy of Sea Buckthorn.
Smith & Lockwood (2010) described an urgent need for active management of the frontal dune ridge at Crosby, including fencing the ridge with delineated routes from the promenade to the shore to reduce trampling pressure. They also suggested use of brushwood fencing to trap sand, coupled with Marram planting, the aim being to promote dune development westwards and reduce sand-blow onto the promenade which has required frequent mechanical clearance for many years. This problem might best be tackled through an integrated management plan for the Coastal Park which could also address similar issues affecting the inner dune ridge, including blow-out development in the northern section and sand-blow into the Marine Lake further south. Such management would also create more amenable surroundings for tourists visiting the Another Place artwork.
Further studies of the Park’s habitats and species seem justified. In particular, an update of the NVC survey is now long overdue, having last taken place in 2004.
