Hydrilla

Hydrilla is a plant found in freshwater. It is a flora that grows up to the surface in water of about 20 feet deep. This very standard 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 flora can grow in oligotrophic (low nutrient) to eutrophic (high nutrient) conditions in water.  
 
The Hydrilla is suited to more mild climates as it will only tolerate temperatures between 20 C and 27 C. The Hydrilla has ample branches that open out upon reaching the surface, shaping mats. The submerged stems of the Hydrilla can be as long as twenty five feet. The Hydrilla roots, also know as Rhizomes, are  often than not off-white or yellow in color. | The roots or Rhizomes of the Hydrilla are frequently yellow or off-white in color. }There are lots of ways a Hydrilla can reproduce. Fragmentation, seeds, tubers and turions (auxiliary buds) are the primary ways the Hydrilla propagates.
 
The Hydrilla has many positives on its side when likened to other aquatic plants. The Hydrilla only needs 1% sunshine to grow. Hydrillas absorb a great deal of foods from the water leaving small for the native plants. Hydrillas grow quickly, contending with indigenous floras, and are consequently believed a noxious pest. The greatest danger of Hydrilla is that it can grow out of control and undetected until it pops out at the surface at the last minute. Hydrillas will oftentimes choke out native aquatic plants because they take up so much surface area absorbing the sunlight and nutrients.
 
Millions of dollars are spent each year on herbicides and harvesting devices in an campaign to keep this floras growth under control. Hydrilla harms the vegetation in the immediate area making it near hopeless for fishermen to fish. Slowed water flow and blocked up irrigation or flood control canals are as a result of Hydrilla over growth. Hydrilla impedes bathers, boaters and fishers alike. When a lot of Hydrilla grows together, it can totally take down that areas water oxygen level.
 
The Elodea and Egeria are frequently confused with the Hydrilla. Hydrilla can be identified by the teeth found on the bottom 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 flora. Also, Egeria has bigger blossoms than the Hydrilla.
 
Hydrilla is consumed by macro and micro invertebrates. Species like ducks, fish, amphibians and reptiles will consume the decomposed remains of the micro and macro organisms that fed on the Hydrilla. Bacteria and fungi break up Hydrillas that die naturally and then create a food called rubble, which many aquatic creatures eat. Ducks ofttimes eat Hydrilla turions and tubers, but this is not a substantial source of food. Ducks will ofttimes feed on the tubers and turions of Hydrilla, but they don’t make a great diet.
