Hydrilla

Hydrilla is a freshwater flora. The Hydrilla will grow to the waters surface from a depth of up to 20 feet. Hydrillas are a familiar marine plant and can grow in a variety of peculiar water sorts. 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 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. The underwater stems of the Hydrilla can be as long as twenty five feet. 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 oftentimes yellow or off-white in color. }There are many ways a Hydrilla can reproduce. Fragmentation, seeds, tubers and turions (auxiliary buds) are the primary ways the Hydrilla propagates.
 
The Hydrilla has many advantages when equated to other floras. Only one percent sunlight is need for the Hydrilla to grow. Hydrillas absorb a great deal of nutrients from the water leaving little for the native floras. Hydrillas can grow very quickly, competing with the indigenous species, and that’s why it is believed a noxious pest. Hydrilla is especially dangerous because it can almost entirely take over a body of water before appearing on the surface. When it covers a big area, all the marine floras that fall under it die due to the lack of sunshine or nutrition. When Hydrilla encompasses a large area, all the other aquatic floras fail because the do not receive enough sunlight or nutrients.
 
Millions of dollars are spent each year on weed killers and harvesting devices in an attempt to keep this floras growth under control. Individuals can’t fish in areas where Hydrilla is found because it so adversely burdens the other plant life in the area. Hydrilla slows down the water flow and totally chokes irrigation and flood-control canals. Hydrilla impedes swimmers, boaters and fishers alike. When a lot of Hydrilla grows together, it can totally take down that areas water oxygen level.
 
Elodea and Egeria are often mixed up for Hydrilla. The aquatic plants Elodea and Egeria are frequently thought to be Hydrilla. Hydrillas have one or more teeth 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 plant. The blossoms the Egeria create are also larger than the Hydrilla. 
 
Macro and micro invertebrates feed on Hydrilla. Upon dying, these micro and macro organisms disintegrate and become food for other land and aquatic wildlife. When Hydrilla dies naturally, they are decayed by bacteria and fungi and the end result is “detritus” a food for several marine invertebrates. Ducks oftentimes 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.
