    Written by Industry Experts Emily Mayer, Aquatic Biologist and Kate Arnao, seasonal team member 

    As its name suggests, mudmat (Glossostigma cleistanthum) is an invasive aquatic plant species that forms dense, green mats in littoral zones. The iconic bunny ear-shaped leaves of mudmat serve as a unique characteristic when identifying this species. The leaves grow in pairs along thin rhizomes, with narrowing stems at the base and widen into an oval shape at the tips.

    Mudmat can thrive both as a submerged and emergent plant depending upon the location within the waterbody. This species generally prefers oligotrophic conditions, consisting of high transparency readings, low pH, and low pond nutrients. They can form “carpet-like” mats along the bottom of waterbodies, averaging from 10,000 to 25,000 plants per square meter, and can reach depths of up to two meters.

    Misconceptions About Lake & Pond Nutrients

    by: SOLitude Lake Management   |   Oct 01, 2018

    lake management

    Written by Erin Stewart, Territory Leader & Aquatic Biologist

    Nutrients are required for all living things to survive. They are metabolized for energy or fuel so organisms can develop and grow. The nutrients humans and animals need are provided by the food we eat. When food is consumed and digested, it provides the fuel to synthesize or produce direct energy. Similarly, plants take up the nutrients they need from soil and the atmosphere through roots and leaves. In lakes and ponds, these nutrients are found suspended in the water and within bottom sediments. Aquatic plants absorb nutrients through roots down in the sediments or leaves. Submerged plants also absorb (CO2) from the water and sunlight that penetrates below the water surface.

    Hydro-raking 101: FAQs About Restoring Water & Prolonging Dredging

    by: SOLitude Lake Management   |   Sep 25, 2018

    hydro-rake

    Everything ages with time. When it comes to your lake or pond, time can take a toll on its health and functionality. Over the lifespan of your waterbody, sediment and organic matter will accumulate, nuisance plants will flourish, water quality will diminish and water depth will decrease. Luckily, you can reverse the aging process and help restore your waterbody back to health with one environmentally-friendly management tool: hydro-raking.

    Are you curious whether this is the management solution for you? Below are some of the most popular questions from our recent hydro-raking webinar hosted by industry experts Joe Onorato, Aquatic Specialist & Business Development Consultant; Jeff Castellani, Director of Mechanical Operations and Keith Gazaille, Aquatic Ecologist & Director of Lake Management for the North and Mid-Atlantic.

    Common Nuisance & Invasive Plants You May Be Mistaking for Waterlilies

    by: SOLitude Lake Management   |   Sep 04, 2018

    waterlily

    Yellow waterlily, white waterlily and watershield can play important roles in aquatic ecosystems when managed properly. 

    When you look out at your lake or pond, you may see some floating, broad-leaved plant species. The most common native species with floating leaves are yellow waterlily (Nuphar variegata), white waterlily (Nymphaea odorata) and watershield (Brasenia schreberi). Depending on region, waterlilies and watershield can be found inhabiting the shallow littoral zones of lakes and ponds, often covering the surface of these waterbodies with floating leaves and flowers. When managed properly, these species occupy an important ecological niche by creating habitat and providing food for aquatic organisms. However, several nuisance and invasive plants share physical characteristics with these beneficial species, making incorrect identification an easy—and potentially catastrophic—mistake. These nuisance and invasive plants rapidly out compete native species, can negatively impact the ecology of the aquatic habitats they invade and can drastically diminish the recreational and aesthetic value of your lake or pond.

    7 Tips to Prevent Harmful Algal Blooms in Your Community’s Waterbodies

    by: SOLitude Lake Management   |   Aug 14, 2018

    A common issue that many communities experience is the growth of pond algae in lakes and ponds used for recreation and drinking water. In community waterbodies, moderate amounts of algae can often signify the waterbody is in good health, but excess algae levels may indicate that the natural balance of the ecosystem has been compromised. Without swift and proper management, certain species of algae, like cyanobacteria, can begin producing harmful toxins.

    New Call-to-action

    Following exposure or digestion of these toxins, humans and animals can experience skin rashes, liver and kidney toxicity, nervous system problems, respiratory complications and even death. Exposure to cyanobacteria also has suspected links to degenerative diseases like ALS, Alzheimer’s and Parkinson’s.

    Invasive Species Highlight: Water Chestnut

    by: SOLitude Lake Management   |   Aug 06, 2018

    Water Chestnut

    Water chestnut has invaded waterways from Canada to Virginia along the East Coast since its introduction in the 1870s. Water chestnut can be identified by its triangular serrated floating leaves arranged in a rosette pattern, radiating from a central stalk. The stalk is rooted to the bottom substrate and covered in feathery submersed leaves.

    Written by Industry Expert Matthew Ward, Fisheries Biologist

    If you own or manage a body of water long enough, you will experience invasive vegetation and algae growth. This growth can be associated with bad smells and dead fish, converting an otherwise pristine waterbody into an ugly mess. Often, a manager’s first reaction is to identify the intruder, apply a fast-acting herbicide/algaecide and wash their hands of the matter. This strategy may work for a while, but unfortunately, growth returns time after time. Managers can eventually enter a cycle where the frequency and severity of invasive growth begins to climb out of control along with expenses. Enter Integrated Pest Management (IPM). IPM considers biological, mechanical and chemical controls alongside adjustments in cultural practices, enabling us to treat the problem, not just the symptoms.

    giant salvinia

    Written by Industry Experts Paul Dorsett, Fisheries Biologist, and Keith Gazaille, Director of Lake Management – North and Mid-Atlantic

    Flag Lake is a 664-acre lake located on Barksdale Airforce Base near Bossier City, Louisiana. The lake is relatively shallow, averaging less than four feet deep, and serves as a valuable aquatic resource to the base and the surrounding communities by providing excellent fish and wildlife habitat, as well as important recreational opportunities in the form of fishing, waterfowl hunting and wildlife viewing. Historically, Flag Lake has suffered from the excessive growth of a variety of plant species, but most notably, invasive hydrilla (Hydrilla verticillata), American lotus (Nelumbo lutea) and water hyacinth (Eichhornia crassipes). In recent years, however, giant salvinia (Salvinia molesta) has dominated the plant assemblage, reaching problematic conditions in 2017 with an estimated 500 acres of water covered in this invasive aquatic plant. To combat this invasive species, SOLitude employed a volumetric management approach that was fairly experimental for an infestation of this magnitude.

    Written by Industry Expert Eric Carnall, Environmental Scientist 

    Alligatorweed (Alternanthera philoxeroides) is a perennial plant native to South America. It was first reported in the United States in 1897. Listed as a prohibited aquatic weed in many states, its growth has caused significant economic and ecological damage throughout the Southern United States.

    Alligatorweed reproduces in North America primarily through vegetative propagation, but seeds have been found as well. Morphologically speaking, alligatorweed can be varied based on the surrounding environment; in fact, it has adapted to grow in both aquatic ecosystems and xeric (desert) habitats. Typically, this invasive plant can be identified by its
