Beavers are large, semiaquatic rodents of the Northern Hemisphere. There are two existing species: the North American beaver and the Eurasian beaver. Beavers are the second-largest living rodents, after capybaras, weighing up to 50 kg (110 lb). They have stout bodies with large heads, long chisel-like incisors, brown or gray fur, hand-like front feet, webbed back feet, and tails that are flat and scaly. The two species differ in skull and tail shape and fur color. Beavers can be found in a number of freshwater habitats, such as rivers, streams, lakes and ponds. They are herbivorous, consuming tree bark, aquatic plants, grasses and sedges.
A herbivore is an animal anatomically and physiologically adapted to eating plant material, for example foliage or marine algae, for the main component of its diet. As a result of their plant diet, herbivorous animals typically have mouthparts adapted to rasping or grinding. Horses and other herbivores have wide flat teeth that are adapted to grinding grass, tree bark, and other tough plant material.
Typha is a genus of about 30 species of monocotyledonous flowering plants in the family Typhaceae. These plants have a variety of common names, in British English as bulrush or reedmace, in American English as reed, cattail, or punks, in Australia as cumbungi or bulrush, in Canada as bulrush or cattail, and in New Zealand as reed, cattail, bulrush or raupo. Other taxa of plants may be known as bulrush, including some sedges in Scirpus and related genera.
Cyperus papyrus, better known by the common names papyrus, papyrus sedge, paper reed, Indian matting plant, or Nile grass, is a species of aquatic flowering plant belonging to the sedge family Cyperaceae. It is a tender herbaceous perennial, native to Africa, and forms tall stands of reed-like swamp vegetation in shallow water.
Saururaceae is a plant family comprising four genera and seven species of herbaceous flowering plants native to eastern and southern Asia and North America. The family has been recognised by most taxonomists, and is sometimes known as the "lizard's-tail family". The APG IV system assigned it to the order Piperales in the clade magnoliids.
Sagittaria latifolia is a plant found in shallow wetlands and is sometimes known as broadleaf arrowhead, duck-potato, Indian potato, or wapato. This plant produces edible tubers that have traditionally been extensively used by Native Americans.
Iris pseudacorus, the yellow flag, yellow iris, or water flag, is a species of flowering plant in the family Iridaceae. It is native to Europe, western Asia and northwest Africa. Its specific epithet pseudacorus means "false acorus", referring to the similarity of its leaves to those of Acorus calamus, as they have a prominently veined mid-rib and sword-like shape. However, the two plants are not closely related. The flower is commonly attributed with the fleur-de-lis.
Aristolochia californica, the California pipevine, California Dutchman's-pipe, or California snakeroot is a perennial woody vine of western North America.
Nuphar lutea, the yellow water-lily, brandy-bottle, or spadderdock, is an aquatic plant of the family Nymphaeaceae, native to northern temperate and some subtropical regions of Europe, northwest Africa, and western Asia. This species was used as a food source and in medicinal practices from prehistoric times with potential research and medical applications going forward.
Sium suave, the water parsnip or hemlock waterparsnip, is a perennial wildflower in the family Apiaceae. It is native to many areas of both Asia and North America. The common name water parsnip is due to its similarity to parsnip and its wetland habitat. The alternate common name hemlock waterparsnip is due to its similarity to the highly poisonous spotted water hemlock.
Hydrocotyle vulgaris, the marsh pennywort, common pennywort, water naval, money plant, lucky plant, dollarweed or copper coin, is a small creeping aquatic perennial plant native to North Africa, Europe, the Caucasus and parts of the Levant.
Pontederia cordata, common name pickerelweed (USA) or pickerel weed (UK), is a monocotyledonous aquatic plant native to the Americas. It grows in a variety of wetlands, including pond and lake margins across an extremely large range from eastern Canada south to Argentina. A few examples include northern rivers, the Everglades and Louisiana.
Peltandra virginica is a plant of the arum family known as green arrow arum and tuckahoe. It is widely distributed in wetlands in the eastern United States, as well as in Quebec, Ontario, and Cuba. It is common in central Florida including the Everglades and along the Gulf Coast. Its rhizomes are tolerant to low oxygen levels found in wetland soils. It can be found elsewhere in North America as an introduced species and often an invasive plant.
Scirpus ancistrochaetus is a rare species of flowering plant in the sedge family known by the common names barbedbristle bulrush and northeastern bulrush. It is native to the northeastern United States from New Hampshire south to Virginia. It used to be found in Quebec but it is now thought to be extirpated there. It was also believed extirpated from the state of New York, but at least one population has been rediscovered in Steuben County in 2010. It is threatened by the loss and degradation of its wetland habitat. It is a federally listed endangered species.
Typha minima, common name dwarf bulrush or miniature cattail or least bulrush, is a perennial herbaceous plant belonging to the Typhaceae family.
Arundinaria gigantea is a species of bamboo known as giant cane, river cane, and giant river cane. It is endemic to the south-central and southeastern United States as far west as Oklahoma and Texas and as far north as New York. Giant river cane was economically and culturally important to indigenous people, with uses including as a vegetable and materials for construction and craft production. Arundinaria gigantea and other species of Arundinaria once grew in large colonies called canebrakes covering thousands of acres in the southeastern United States, but today these canebrakes are considered endangered ecosystems.
A cypress dome is a type of freshwater forested wetland, or a swamp, found in the southeastern part of the United States. They are dominated by the Taxodium spp., either the bald cypress, or pond cypress. The name comes from the dome-like shape of treetops, formed by smaller trees growing on the edge where the water is shallow while taller trees grow at the center in deeper water. They usually appear as circular, but if the center is too deep, they form a “doughnut” shape when viewed from above. Cypress domes are characteristically small compared to other swamps, however they can occur at a range of sizes, dependent on the depth.
Typocerus lugubris is a species of flower longhorn in the beetle family Cerambycidae. It is found in North America. It has been observed mating on Saururus cernuus, with the female consuming pollen from the plant.
Strangalia luteicornis is a species of flower longhorn in the family of beetles known as Cerambycidae. It is found in North America. It has been observed mating on Hydrangea arborescens and Saururus cernuus, with the female consuming pollen from the latter plant.
Juncus marginatus is a species of flowering plant, it is a type of rush with the common names of margined rush and grass-leaf rush.
