Hydrilla is a fresh water flora. This plant grows to the surface of the water from a depth as great as 20 feet. Hydrillas are a common marine flora and can grow in a variety of peculiar water types. Hydrillas can grow in as little as a few inches of water or in as much as 20 feet of water. The Hydrilla can flourish in either oligotrophic (low nutrient) or eutrophic (high nutrient) water conditions.
The Hydrilla is suited to more mild climates as it will only tolerate temperatures between 20 C and 27 C. Upon extending to the surface, the Hydrillas full branches spread out to form a thick mat. It might have stems as long as 25 feet underwater in water! Rhizomes, another name for the roots, are off-white to yellowish in color. off-white or yellowish in color. | The roots or Rhizomes of the Hydrilla are often yellowish or off-white in color. } The Hydrilla has numerous ways of reproduction. Fragmentation, seeds, tubers and turions (auxiliary buds) are the primary ways the Hydrilla propagates.
The Hydrilla has many advantages when likened to other plants. Only one percent sunshine is need for the Hydrilla to grow. These plants also take up the rich nutrients from its place so that the other native sources can’t get it. Hydrillas are marked as a pestilent pest because of their fast growth rate that makes them a threat to other native plants. 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. When it covers a big area, all the aquatic plants that fall under it die due to the lack of sunshine or nutrition. When Hydrilla encompasses a large area, all the other aquatic plants fail because the do not receive enough sunshine or foods.
Millions of dollars are spent each year on weed killers and harvesting devices in an campaign to keep this floras growth under control. Since it harms the flora around it, people can’t even fish around areas these grow. Slowed water flow and blocked up irrigation or flood control canals are as a result of Hydrilla over growth. Bathing, yachting and angling can not be properly done in areas when Hydrilla has taken hold. Mass amounts of Hydrilla can seriously lower the oxygen levels of the water it is growing in.
The Elodea and Egeria are ofttimes confused with the Hydrilla. In the case of a Hydrilla, there is one or more teeth located at the undersurface of the midrib. Elodea and Egeria do not have teeth present on their undersides. Neither Elodea nor Egeria has teeth on their undersurface. Due to these teeth, we feel the roughness of these plants when we rub over from its base to the tip. The blossoms the Egeria produce are also larger than the Hydrilla.
Hydrilla turns into solid food for macro and micro invertebrates. Species like ducks, fish, amphibians and reptilians will consume the decomposed remains of the micro and macro organisms that fed on the Hydrilla. When Hydrilla dies naturally, they are decomposed by bacteria and fungi and the end result is “detritus” a food for several marine invertebrates. 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.
