Undesirable aquatic plants disturb the vital balance of nutrients and oxygen in the water body and can wreak havoc on outside activities. Lakes tend to be temporary features, geologically speaking, of the landscape; most are only 10-20,000 years old. Bogs support some of the most interesting plants in the United States (like the carnivorous Sundew) and provide habitat to animals threatened by human encroachment. Please be aware that lake or pond treatments are complex and require proper plant ID, accurate acreage and depth measurements, and sometimes multiple products for proper control. One of the best ways of bringing more wildlife into an area, ponds can be very diverse, supporting similar aquatic plants to lakes, and even more large invertebrates than rivers. Lakes and ponds are characterized by three main habitats: the pelagic zone, the littoral zone, and the benthic zone. Calmer rivers or streams may have emergent plants, or plants that are grounded to the waterway’s bed, but their stems, flowers and reach extend above the water line. Lake Tanganyika on the African continent is … Alkali wetlands are characterized by a pH above 7 and a high concentration of salts. Ponds with low nutrient concentrations are described as infertile and produce limited quantities of aquatic life. Aquatic plants serve an important purpose in an aquatic environment. Lake Baikal, in Asia, is the oldest at 50-75 million years old. Wisconsin Lake & Pond Resource […] Class VI - Alkali Ponds and Lakes are wetlands where deep water is typically not permanently present. Scientists that study lakes and ponds are known as limnologists. In this overview we hope to describe a few of the biotic (plant, animal and micro-organism) interactions as well as the […] Wildlife will use the pond and shoreline for watering, feeding and hiding from predators. Status of Bogs Bogs in the United States are mostly found in the glaciated northeast and Great Lakes regions ( northern bogs ) but also in the southeast ( pocosins ). Beneficial aquatic plants have many values including filtering nutrients and toxic chemicals, stabilizing shorelines and providing important fish and wildlife habitat. The best ponds for wildlife have shallow margins with a fringe of vegetation and nearby plant cover for amphibians and insects with terrestrial life stages. Algal production is limited in waters by the availability of nutrients, mainly nitrogen and phosphorus. Lakes are normally divided into 4 zones of freshwater aquatic communities: Littoral zone: The area adjacent to the shore of the lake where plants thrive Ponds and lakes. Lakes and Ponds represent a freshwater biome type that is generally referred to in the scientific community as a lentic ecosystem (still or standing waters). Ponds and lakes are sometimes referred to as lentil ecosystems, meaning they consist of standing or still waters. An abundance reproduction of the aquatic plants in your lake or pond can have harmful effect on its inhabitants. Essentially, the waters don’t flow like streams and rivers. They play a key component in maintaining and enhancing the ecological balance in ponds, lakes, wetlands, rivers, and streams. In large lakes, the pelagic zone makes up most of the lake's volume. Understand that native plants play a vital role in the lake and pond ecosystem and complete removal may have detrimental impacts. The dominant plants are generally salt tolerant and include red swampfire and spiral ditchgrass. These wetlands are especially attractive for shore birds. Dominant plants include crowberry, grass, sedge, cottongrass, moss, alder, and willow. The relatively few ancient lakes are of tectonic origin and occupy rift valleys. The pelagic zone is the open water area of lakes and ponds. Habitat in the Refuge consists of berry-producing, low-growing bush tundra interspersed with numerous lakes, ponds and streams; thickets of alder brush in discrete zones and in riparian areas; coastal marshes; and barren glacier-topped mountains. Permits may be required!! The littoral zone … Three types of plants usually live in rivers and streams: algae, mosses and submerged plants.
