Marshland in the context of "Hula Valley"

Aquatic plants, also referred to as hydrophytes, are vascular plants and non-vascular plants that have adapted to live in aquatic environments (saltwater or freshwater). In lakes, rivers and wetlands, aquatic vegetations provide cover for aquatic animals such as fish, amphibians and aquatic insects, create substrate for benthic invertebrates, produce oxygen via photosynthesis, and serve as food for some herbivorous wildlife. Familiar examples of aquatic plants include waterlily, lotus, duckweeds, mosquito fern, floating heart, water milfoils, mare's tail, water lettuce, water hyacinth, and algae.

Aquatic plants require special adaptations for prolonged inundation in water, and for floating at the water surface. The most common adaptation is the presence of lightweight internal packing cells, aerenchyma, but floating leaves and finely dissected leaves are also common. Aquatic plants only thrive in water or in soil that is frequently saturated, and are therefore a common component of swamps and marshlands.

Archaea (/ɑːrˈkiːə/ ar-KEE-ə) is a domain of organisms. Traditionally, Archaea included only its prokaryotic members, but has since been found to be paraphyletic, as eukaryotes are known to have evolved from archaea. Even though the domain Archaea cladistically includes eukaryotes, the term archaea (sing. archaeon /ɑːrˈkiːɒn/ ar-KEE-on; from Ancient Greek ἀρχαῖον arkhaîon 'ancient') in English still generally refers specifically to prokaryotic members of Archaea. Archaea were initially classified as bacteria, receiving the name archaebacteria (/ˌɑːrkibækˈtɪəriə/, in the Archaebacteria kingdom), but this term has fallen out of use. Archaeal cells have unique properties separating them from Bacteria and Eukaryota, including: cell membranes made of ether-linked lipids; metabolisms such as methanogenesis; and a unique motility structure known as an archaellum. Archaea are further divided into multiple recognized phyla. Classification is difficult because most have not been isolated in a laboratory and have been detected only by their gene sequences in environmental samples. It is unknown if they can produce endospores.

Archaea are often similar to bacteria in size and shape, although a few have very different shapes, such as the flat, square cells of Haloquadratum walsbyi. Despite this, archaea possess genes and several metabolic pathways that are more closely related to those of eukaryotes, notably for the enzymes involved in transcription and translation. Other aspects of archaeal biochemistry are unique, such as their reliance on ether lipids in their cell membranes, including archaeols. Archaea use more diverse energy sources than eukaryotes, ranging from organic compounds such as sugars, to ammonia, metal ions or even hydrogen gas. The salt-tolerant Halobacteria use sunlight as an energy source, and other species of archaea fix carbon (autotrophy), but unlike cyanobacteria, no known species of archaea does both. Archaea reproduce asexually by binary fission, fragmentation, or budding; unlike bacteria, no known species of Archaea form endospores. The first observed archaea were extremophiles, living in extreme environments such as hot springs and salt lakes with no other organisms. Improved molecular detection tools led to the discovery of archaea in almost every habitat, including soil, oceans, and marshlands. Archaea are particularly numerous in the oceans, and the archaea in plankton may be one of the most abundant groups of organisms on the planet.

Gouda (Dutch pronunciation: [ˈɣʌudaː] ) is a city and municipality in the west of the Netherlands, between Rotterdam and Utrecht, in the province of South Holland. Gouda has a population of 75,000 and is famous for its Gouda cheese, stroopwafels, many grachten, smoking pipes, and its 15th-century city hall. Its array of historic churches and other buildings makes it a very popular day-trip destination.

In the Middle Ages the Van der Goude [nl] family founded a settlement at the location of the current city and built a fortified castle alongside the banks of the Gouwe River, from which the family and the city took their names. Locals long called the settlement Ter Goude, or Tergou or Tergouw [nl] for short.The area, originally marshland, developed over the course of two centuries. By 1225, a canal was linked to the Gouwe and its estuary became a harbour. In 1272 Floris V, Count of Holland granted the city city rights.

The Marais Poitevin (pronounced [maʁɛ pwatvɛ̃]) or Poitevin Marsh is a large area of marshland in the former province of Poitou in western France.

A riparian forest or riparian woodland is a forested or wooded area of land adjacent to a body of water such as a river, stream, pond, lake, marshland, estuary, canal, sink, or reservoir. Due to the broad nature of the definition, riparian woodlands have a huge diversity of characteristics including but not limited to soil composition, microclimates, and vegetative structures. However, among the varied range and landscapes, one factor stays constant: a high rate of primary productivity. This makes riparian forests hugely important centers of nutrient recycling.

A floating island is a mass of floating aquatic plants, mud, and peat ranging in thickness from several centimeters to a few meters. Sometimes referred to as tussocks, floatons, or suds, floating islands are found in many parts of the world. They exist less commonly as an artificial island. Floating islands are generally found on marshlands, lakes, and similar wetland locations, and can be many hectares in size.
