Spaans Lagoen

Spaans Lagoen, which translates to "Spanish lagoon", is a coastal bay and wetland area of Aruba. Designated as a Ramsar site since 1980, [2] and in February 2017, it was included within the boundary of the Arikok National Park. [3] It is the only inner bay of Aruba and was formed during the last ice age. [4] This ecosystem features tidal mudflats and mangrove swamps, serving as a vital feeding and breeding ground for birds. [2] Spaans Lagoen is one of the highest biodiversity areas on Aruba. It is also adjacent to Arikok National Park. [5] [6]

Overview

Spaans Lagoen stretches approximately 2 kilometres (1.2 mi) in length and ranges in width from 200 to 500 metres (660 to 1,640 ft) wide, [6] covering an area of 70 hectares (170 acres). [3] Its distinctive tidal influence has given rise to a rare ecosystem, [4] with its shores covered by mangroves. This area plays a crucial role as a feeding and breeding ground for birds and a nursery for reef fish and crustaceans. [6] Palm Island is located at the mouth of Spaans Lagoen, with Frenchman's Pass located to the north. [4]

History

Settlement archaeology

Around 4500 BP, the ABC islands were frequented by fishermen and gatherers from the Venezuelan or possibly Colombian coast, drawn to the islands for their abundant shellfish, particularly Lobatus gigas. They set up temporary camps near mangrove areas and lagoons on Aruba, notably Spaans Lagoen. Evidence of human activity, including charcoal deposits, has been found in sediment layers at Frenchman's Pass (Spaans Lagoen) dating to around 1000 BC. [7]

Ecological environment

Habitats

Spaans Lagoen Bay

Spaans Lagoen has two main bodies of water: the channel and the lagoon. It serves as a vital area for recruiting and raising, supporting adult populations from surrounding ecosystems. Water birds, including birds of prey like Ospreys, use the bay as a feeding ground, often seen catching fish. [3]

Mangrove forest

The shores of Spaans Lagoen Bay, lined with mangroves, play a crucial role in preserving the region's biological diversity. Within this mangrove forest, four different mangrove species can be found: Red Mangrove ( Rhizophora mangle ), [8] Black Mangrove ( Avicennia germinans ), [9] White Mangrove ( Laguncularia racemosa ), [10] and Buttonwood ( Conocarpus erectus ). [11] These mangroves serve as vital nurseries and sanctuaries for numerous reef fish and crustaceans. Additionally, the mangroves act as breeding and roosting sites for a variety of migratory and non-migratory bird species, providing support for wintering and foraging wetland birds, including various Sandpipers, Egrets, and Herons. [3]

Mudflats

The mudflats in the inland section of the Spaans Lagoen border the mangrove forest and experience daily tidal inundation. Numerous bird species come here during the day to search for food. The drier sections of the mudflats serve as ideal habitats for Aruban Burrowing Owls ( Athene cunicularia arubensis ), which create their burrows. Additionally, during the rainy season, land crabs can be observed crossing the mudflats in search of water to lay their eggs. [3]

Rooi

The mudflats are connected to three dry river creeks or Arroyo, known as rooi in Papiamento. These roois only have water after heavy rainfall. Two of them, Rooi Bringamosa and Rooi Taki, are part of the Arikok National Park, extending from the northeastern to the southwestern coast of Aruba. The third rooi is Rooi Frances (Frenchman's Pass). Roois often feature fertile soil and a high water table, making them ideal for fruit trees like Sweet Tamarind and Spanish Lime. Shaded areas within roois can retain water for longer periods, serving as oasis for land animals like Eastern Cottontail Rabbits and supporting diverse aquatic life, including various species of Dragonflies and the Colombian Four-eyed Frog. [3]

Aruba Lava Formation

The northeastern border of the Spaans Lagoen extends from the volcanic rock and sediment typical of Arikok National Park. Similar habitats are found here, featuring various types of cacti and iconic endemic species like the Aruban Rattlesnake ( Crotalus unicolor ) and Brown-throated Parakeet (Eupsittula pertinax). [3]

Limestone cliffs and terraces

Limestone cliffs and terraces encircle the Spaans Lagoen from nearly all directions. These areas exhibit low vegetation and a xeric landscape, creating a distinct contrast within the site. They are dominated by different species of Aloe, remnants of the former Aloe plantations. Crested Caracaras are often spotted perched on the cliffs, keeping watch for their next meal. [3]

Environmental impact

The lagoon is located halfway between the Queen Beatrix International Airport and the town of San Nicolaas. In 2016, the Green Corridor was constructed to provide better access to San Nicolas, including the construction of a bridge over Spaans Lagoen. [4] During the bridge construction, a section of the mangrove forest was damaged. To address this, an S-shaped canal was created to compensate for the damage and facilitate mangrove regeneration.

The Magdalena-Santa Marta mangroves ecoregion covers the mangrove forests along the coast of Colombia on the Caribbean Sea, from Gulf of Urabá in the west at the Colombia-Panama border to the Guajira Peninsula in the east. The region is relatively dry, with low precipitation and high evapotranspiration, so the mangroves depend for water and nutrients on the rivers flowing across the estuarine plain from the Sierra Nevada de Santa Marta mountains to the east. Efforts are currently underway to restore mangroves degraded by development and road building from the 1950s to 1980s.

<span class="mw-page-title-main">Mexican South Pacific Coast mangroves</span>

The Mexican South Pacific Coast mangroves ecoregion covers the mangrove sites along the coast of the Pacific Ocean coast of Mexico, across the states of Michoacán, Guerrero, and Oaxaca. These mangrove forests are mostly around lagoons, typically those fed by rivers from the interior in the Sierra Madre del Sur Mountains. The ecoregion is small: collectively, it covers only 1,295 km2.

<span class="mw-page-title-main">Moist Pacific Coast mangroves</span>

The Moist Pacific Coast mangroves ecoregion covers a series of disconnected mangrove sites along the Pacific Ocean coast of Costa Rica and Panama. These sites occur mostly on coastal flatlands around lagoons, particularly where rivers from the inland mountains reach the sea, bringing fresh water to the coastal forests. The area is in a transition zone from the drier coastline to the north; rainfall in this ecoregions is over 2,000 mm/year, and reaches over 3,600 mm/year at the southern end.

<span class="mw-page-title-main">Rio Negro–Rio San Sun mangroves</span>

The Rio Negro-Rio San Sun mangroves ecoregion covers a series of small of discontinuous mangrove forests on the Caribbean Sea coast of Costa Rica, from a small portion inside the border with Nicaragua in the west to the border with Panama in the east. The coast on this stretch is a flat, alluvial plain, and mangroves are only a small part of a diverse patchwork of local habitats including swamps, mixed rainforests, coastal lagoons, sea grass beds, and sandy beaches. Much of the territory is "blackwater river" in character - slow-moving channels in wooded swamps with water stained by decayed matter. These mangroves are periodically damaged by hurricanes, such as in 1988 from Hurricane Joan, but are able to regenerate.

The Trinidad mangroves ecoregion covers the separate mangrove forest areas on the coast of the island of Trinidad, in the country of Trinidad and Tobago. The character of the mangroves is affected by the large amount of fresh water flowing out of the Orinoco River and Amazon River to the south, which flow northwest around the island. The mangroves of Trinidad are found on all coasts, and are usually in the estuaries of rivers, but also found in coastal lagoons.

<span class="mw-page-title-main">Usumacinta mangroves</span>

The Usumacinta mangroves ecoregion covers the mangrove forests ont the Gulf Coast of Mexico, around the margins of the Laguna de Términos. The "Ends" in the name refer to the mouths of the rivers that empty into the lagoon, including the Usumacinta River. This region, which is due south of the mouth of the Mississippi River across the Gulf of Mexico, receives an estimated one-third of the wintering birds migrating on the Mississippi Flyway. It is estimated that the lagoon supports 90 endangered species.
