Mangrove swamp in the context of "Semi-aquatic"

The parish of Christ Church is one of eleven in Barbados. It has a land area of 57 km (22 sq mi) and is found at the southern end of the island. Christ Church has survived by name as one of the original six parishes created in 1629 by Governor Sir William Tufton.

The parish contains the Sir Grantley Adams International Airport as well as the last remaining mangrove swamp in the country, the Graeme Hall Nature Sanctuary. Under Barbados's historic vestry, the main parish church was originally seated near Dover. After it and the courtyard were destroyed by flood in 1669, the main parish church moved to Oistins area, becoming the main town and former capital of the parish. The South Point Lighthouse is located in South Point, Christ Church, between Atlantic Shores and Green Garden, also in Christ Church.

The marine iguana (Amblyrhynchus cristatus), also known as the sea iguana, saltwater iguana, or Galápagos marine iguana, is a species of iguana found only on the Galápagos Islands (Ecuador). Unique among modern lizards, it is a marine reptile that has the ability to forage in the sea for algae, which make up almost all of its diet. Marine iguanas are the only extant lizard that spends time in a marine environment. Large males are able to dive to find this food source, while females and smaller males feed during low tide in the intertidal zone. They mainly live in colonies on rocky shores where they bask after visiting the relatively cold water or intertidal zone, but can also be seen in marshes, mangrove swamps and beaches. Large males defend territories for a short period, but smaller males have other breeding strategies. After mating, the female digs a nest hole in the soil where she lays her eggs, leaving them to hatch on their own a few months later.

Marine iguanas vary in appearance between the different islands and several subspecies are recognized. Although relatively large numbers remain and it is locally abundant, this protected species is considered threatened, primarily from El Niño cycles, introduced predators and chance events like oil spills.

The brown pelican (Pelecanus occidentalis) is a bird of the pelican family, Pelecanidae, one of three species found in the Americas and one of two that feed by diving into water. It is found on the Atlantic Coast from New Jersey to the mouth of the Amazon River, and along the Pacific Coast from British Columbia to Peru, including the Galapagos Islands. The nominate subspecies in its breeding plumage has a white head with a yellowish wash on the crown. The nape and neck are dark maroon–brown. The upper sides of the neck have white lines along the base of the gular pouch, and the lower fore neck has a pale yellowish patch. The male and female are similar, but the female is slightly smaller. The nonbreeding adult has a white head and neck. The pink skin around the eyes becomes dull and gray in the nonbreeding season. It lacks any red hue, and the pouch is strongly olivaceous ochre-tinged and the legs are olivaceous gray to blackish-gray.

The brown pelican mainly feeds on fish, but occasionally eats amphibians, crustaceans, and the eggs and nestlings of birds. It nests in colonies in secluded areas, often on islands, vegetated land among sand dunes, thickets of shrubs and trees, and mangroves. Females lay two or three oval, chalky white eggs. Incubation takes 28 to 30 days with both sexes sharing duties. The newly hatched chicks are pink, turning gray or black within 4 to 14 days. About 63 days are needed for chicks to fledge. Six to 9 weeks after hatching, the juveniles leave the nest, and gather into small groups known as pods.

Harrisia simpsonii, or Simpson's applecactus, is a species of cactus in the Trichocereeae tribe.

It grows in the state of Florida, in the Southeastern United States. It may be found growing on shell mounds, mangrove swamps or on high hammocks, and may be associated with buttonwood (Conocarpus erectus). It is threatened by collecting for horticulture.

Graeme Hall Nature Sanctuary occupies 42 per cent of the Ramsar wetland at Graeme Hall, in Christ Church, Barbados. It is currently managed by the Barbados Wetlands Trust and the Protector of the Trust is Anthony Da Silva. The Trust was formed by Da Silva in late 2024 and the property was purchased in December 2024.

The sanctuary is home to the Graeme Hall Swamp, a mangrove swamp which was a popular tourist attraction until about 2006. However, due to an ongoing dispute between the owner and the Barbados government over uncontrolled pollution, allegedly from bordering government-owned land, it has been closed to the public. Since about 2008 it has increasingly suffered from raids and poaching by locals about which the local police are reportedly doing nothing.
