Site description 

Rendezvous Bay Pond is a brackish pond located on the south western coastline of Anguilla. It consists of one main basin. The land to the north and east of the pond gradually increases in elevation with the distance. The land to the south and west is relatively flat. The pond is marl substrate on its northern side and sand substrate on its southern side. 

The western shore, within an area equalling to about half an acre, was infilled. It is separated from the pond only by a paved road which runs along western end of the pond. There is an unpaved, sandy road south of the pond along with access pathways/roads to the east and north. The Anguilla Great House Hotel and Old Caribe Restaurant are located behind the road on the western side of the pond. The abandoned Old Rendezvous Bay Hotel lined the southern road. The northern side of the pond has two villas and two residential homes. The eastern side of the pond is relatively undeveloped but its fields are used for animal grazing.

Vegetation is very sparse around the edges of the pond especially on its southern side and western end. The vegetation on the eastern end of the pond is heavily grazed by cows as well as by sheep and goats. The vegetation which is most dense on the eastern end of the pond is mainly scrub plants while buttonwood mangroves line the western end of the pond. The south side of the pond is mainly grasses as well as a few other salt tolerant plants, including the morning glory and cow bean vines.

The western end of the pond has been subject to some infilling and pollution, most recently for the provision of a parking lot for guests to the hotel and beach. This has resulted in a parking lot filled with pools of water during heavy rains. The material used to infill the pond was construction waste and pieces pieces of used steel, old fencing which is rusting and concrete has potential to affect the quality of water within the pond as well as harm those birds which particularly like this area for feeding.

Hydrological value:

This pond consists of a single shallow, brackish basin. The pond receives freshwater from rainfall and run off. Springs are also a source of freshwater for this pond. The pond has water within its basin year round. Its salt content can be attributed to the nearby bay with salt water seeping into the pond through the thin strip of sandy beach separating the pond and sea. Salinity levels, however, have not been monitored within the pond. 

There is a on rock wall which splits the pond roughly in half. The walls served to limit water movement into the salt producing part of the pond until the end of commercial salt harvesting in Anguilla in the 1970’s.

Currently, monitoring of salinity, phosphates, nitrates, phosphates, pH, turbidity, dissolved oxygen and other gasses does not occur.

Key Biodiversity 

Overview of bird interests:

Bird numbers on this pond remained steadily at slightly above the 20 birds between 2007- 2011 with the exception of 2009 where the number observed doubled.

During this period, an average of 21 species was observed. Of these species, the most abundant species were White-cheeked pintail, Black-necked stilt, and Killdeer.

The pond is most active during the spring and summer, coinciding with the spring and fall bird migration periods.

Overview of botanical interests:

Additional studies required.

Overview of other biodiversity interests:

The invasive Green Iguana has been seen in the vegetation surrounding the pond. The Lesser Antilleans Iguanas on the island have been mating with the Green Iguanas which result in sterile offspring. The Anguilla National Trust has completed a project in 2000 to investigate the distribution and population of the Lesser Antillean Iguana (iguana delicatisima), their threats, ecology and diet. Lesser Antillean Iguanas are listed as endangered within the IUCN’s Redlist of Threatened Species.
