Hydrilla
Hydrilla is a flora found in fresh water. It is a flora that matures up to the surface in water of about 20 feet deep. This very familiar water plant can be found in all types of water: rivers, lakes, marshes, springs and the like. Hydrillas can grow only a few inches in water, but they can also grow to about 20 feet deep underwater. This plant can grow in either oligotrophic (low nutrient) or eutrophic (high nutrient) water.
The tolerance temperature level of a Hydrilla is 20o C to 27o C; so, it can’t stand harsh climates. This freshwater plant, Hydrilla, branches copiously and when it reaches the surface, it spreads its branches and forms dense mats. The underwater stems of the Hydrilla can be as long as 25 feet. The Hydrilla roots, also know as Rhizomes, are ofttimes than not off-white or yellow in color. | The roots or Rhizomes of the Hydrilla are often yellowish or off-white in color. }There are many ways a Hydrilla can reproduce. Fragmentation, from seeds, from tuber, and turions (auxiliary buds) are ways how this pest procreates.
When compared with other plants the Hydrilla has several advantages. The Hydrilla only needs 1% sunlight to grow. native floras in the same area as a Hydrilla get insubstantial amounts of foods because of the Hydrillas absorption rate. Hydrillas can grow very quickly, competing with the indigenous species, and that’s why it is believed a pestilent pest. Hydrilla is especially dangerous because it can almost entirely take over a body of water before appearing on the surface. Hydrillas will often choke out native marine plants because they take up so much surface area absorbing the sunlight and nutrients.
Each year, millions of dollars worth of herbicides and mechanical harvesters are used to keep this horrific pest under proper control, so that it doesn’t cross the limit. Individuals can’t fish in areas where Hydrilla is found because it so adversely burdens the other flora life in the area. Slowed water flow and blocked up irrigation or flood control canals are as a result of Hydrilla over growth. Hydrilla impedes swimmers, boaters and fishermen alike. Oxygen levels in waters full of Hydrilla can frequently drop severely.
The Elodea and Egeria are oftentimes mixed up with the Hydrilla. In the case of a Hydrilla, there is one or more teeth located at the underside of the midrib. Elodea and Egeria do not have teeth present on their undersides. Neither Elodea nor Egeria has teeth on their bottom. Because of the teeth, Hydrilla will feel rough. Hydrilla will feel rough due to the presence of the teeth on the underside of the plant. Also the Hydrilla has smaller flowers than the Egeria.
Hydrilla turns into food for macro and micro invertebrates. Species like ducks, fish, amphibians and reptilians will consume the decayed remains of the micro and macro organisms that fed on the Hydrilla. Bacteria and fungi decompose Hydrillas that die naturally and then produce a food called rubble, which many marine creatures eat. Ducks frequently eat Hydrilla turions and tubers, but this is not a substantial source of food. Ducks will frequently feed on the tubers and turions of Hydrilla, but they don’t make a great diet.
