Road Salt Pond


Site description (2013 baseline):

Site location and context
This large near-circular pond is the most recognizable wetland on Anguilla lying immediately to the west of the settlement, a popular beach among both local residents and visitors and port of Sandy Ground.  Best viewed from the southern ridge of Sandy Ground (South Hill), the settlement and pond together comprise perhaps the most iconic landscape on mainland Anguilla. 

The pond is bordered to the west by a dune system, now largely flattened and built upon.  To the north, east and south, some of the highest hills on Anguilla curve around the pond which forms a valley bottom at their base.  The hills are clothed in low dry forest scrub with scattered trees and create the predominant water catchment area of the pond. 

Over the years substantial infilling of the pond has taken place. Indeed – and most recently (1996-1997) - the pond’s southern catchment was filled to accommodate the raising and widening of the road as well as on the northern corner to upgrade a small track into a paved road. In 2005, the pond south-western corner of the pond was infilled to create parking space for shipment trailers. The pond is now closely bordered by a ring road although on the eastern side; this is set back behind fringing vegetation, a truck park and a sports field.  In addition to the settlement directly within Sandy Ground, significant residential housing and villas line the North and South Hill slopes and ridges. 

Dating back to the settlement period of the Amerindians, Road Pond has been used as a source of salt. Saltworks infrastructure in the form of rock walls and dams within the pond still line its inner perimeter. Artefacts and images preserving, celebrating and recognising this place of Anguillian history and heritage can be found at a bar and restaurant that used to be the Salt Factory Pumphouse. 


Key biodiversity
This is a spectacular pond for wetland birds and over the course of a year it will attract the widest range of species of any site on Anguilla. While average bird numbers on this pond per year fluctuate annually, they tend to fluctuate around a low average of just over 500 birds and a high of about 750 birds.

Breeding species include Green heron, White-cheeked pintail and Common moorhen around the edges of the pond and littoral vegetation. Pintails tend nest when water levels are high and have been seen with ducklings in most months.  Wading birds including Killdeer, Wilson’s plover and Black-necked stilt nest in drier areas and on the saltworks. In recent years least terns have been recorded breeding on the salt pond walls.  The dry forest and scrub that surround the pond hold breeding populations of most of Anguilla’s resident land birds including Mangrove cuckoo and restricted range species, Caribbean elaenia and Lesser Antillean bullfinch.  In the period May to August, Antillean nighthawks can be seen over North Hill village.

Several species of seabirds will visit the pond to feed, bathe, and/or roost on these salt pond walls.  These include Brown pelicans, Magnificent frigatebirds and Royal, Sandwich and Least terns.  Regionally important numbers of Laughing gull arrive in April, gathering on salt pond walls to roost before dispersing to breeding sites on the outlying cays.  

Herons and egrets are seen year round but highest numbers are present in the winter months when they will roost in bushes on the eastern shore.  

A mixture of extensive areas of shallow water and muddy edges attracts large numbers of migratory waterbirds with a peak of over 1700 birds present in September 2008, including a flock of over 700 Semi-palmated sandpipers.  Over 30 species of waterbirds have been recorded here and it is among the best places in the Eastern Caribbean to see breeding species from the Arctic such as Stilt sandpipers, Semi-palmated sandpipers and Pectoral and White-rumped sandpipers.  Many of these species stay throughout the winter months.  The high numbers of birds present on passage and in winter provide prey for Peregrine falcons and Merlin while Osprey will catch fish in the bay and the pond. 


Habitat and land use
Main Habitats: The shoreline vegetation is poorly developed on all but the eastern shore because of built development, the ring road, and the on-going vegetation maintenance that borders both the pond and the road.  The pond also suffers heavy grazing from free-roaming and tethered goats and sheep.  On the northern side, the road has left a narrow strip of bushes and shore-line vegetation which appears to be heavily managed thereby leaving little cover for birds.  

The western shore holds areas of grassland and some emergent vegetation which are scarce on Anguilla.  Species include the spike rush Eleocharis mutata.  There are also sandy areas with some remnant dune vegetation.  There has also been some planting of introduced ornamental plants in the north-west corner. A narrow strip of vegetation on the southern shore drops down a steep bank to the water’s edge. 

Land Use: The Pond was formerly the centre of Anguilla’s salt industry with the pond being used for salt harvesting until the 1970’s when it became unprofitable.  The former pump-house was restored as a bar and restaurant in 1995 and this is now a low-key museum as it retains part of the industrial heritage including scales, grinding equipment and the first diesel engine on Anguilla. 

The grasslands on the western side are grazed by tethered and free-roaming goats and the latter will wander onto the salt pond walls when water levels are low. 
The site is used for eco-tourism through guided bird watching walks and the rich natural resources are also used for educational field studies.  Young children have also used the pond to race miniature boats.

The pond also provides habitat for the Least tern, a species considered to be  endangered in the countries along its migration route. The pond is used for research on the population trends of this bird as well as all others observed during the Anguilla National Trust’s Monthly Bird Monitoring Programme. Results of monitoring activities are published in biennial status reports.  


Pressure/threats to key biodiversity
There has been significant in-filling in the past particularly on the seaward side at Sandy Ground.  A large pond on the western side of the road, that was once presumably connected to the main pond, was filled in for a truck park in 2005.  There is still some evidence of rubble and vegetation being tipped on the edges of the pond in the north-west corner. 
 
Fringing vegetation continues to be cleared especially on the northern shore.  
The quality of water in the pond is unknown.  An increase in residential and commercial development within the catchment area could result in increased sedimentation from run-off or eutrophication from septic tank overflows.
 Surrounding vegetation is heavily grazed by free-roaming goats and sheep.  These may disturb waterbirds on the salt pond walls.  Feral dogs may also disturb waterbirds round the pond edges. 

A proposal has been submitted to re-establish salt works operations within the pond. The project proposal, to date is only at outline level and the developer has agreed to complete an Environmental Impact Assessment (EIA). If permission is granted to allow the project, major changes would be made to perimeter of the pond which is the most active area for bird life.
