Floods, Droughts and Invasive Species some we control others are uncontrollable 

As many Californians know we can not control the lack of rain and snow during a drought.  As many in Louisiana, Texas, Oklahoma, Kansas known we can not control too much rain in a short amount of time.  However, as outdoorsmen and woman it is our duty to protect or vital ecosystems from the things we can protect them from......invasive species.

What is an aquatic invasive species?

Aquatic invasive species (AIS) (sometimes called exotic, invasive, nonindigenous or non-native) are aquatic organisms that invade ecosystems beyond their natural, historic range. Their presence may harm native ecosystems or commercial, agricultural, or recreational activities dependent on these ecosystems. They may even harm our health.

People have helped spread species around the globe for centuries either intentionally or unintentionally. Intentional introductions involve the deliberate transfer of nuisance species into a new environment. An example of this would be someone who dumps the contents of their home aquarium into a lake. Unintentional introductions occur when invasives are transferred accidentally. For instance, zebra mussels can be spread when ballast water used for ship stability is exchanged.

In fact, aquatic nuisance species can be spread many ways including ships, boats, barges, aquaculture, aquatic recreation (fishing, hunting, boating, diving, etc.), water gardening, seaplanes, connected waterways and many other pathways. Through these and other means, thousands of terrestrial and aquatic invasive species have been introduced into our country, costing us billions annually.

Examples of Aquatic Invasive Species:

 

  1. zebra mussels,

  2. Chinese mitten crabs,

  3. hydrilla,

  4. Eurasian watermilfoil,

  5. nutria,

  6. sea lamprey,

  7. Asian carp, and

  8. New Zealand mudsnail.

Some of these organisms seem to have little impact while others are devastating. Here are two examples of harmful species:

Zebra mussels

Brought here from Europe in ships’ ballast water; zebra mussels were first discovered in the Great Lakes region in 1988. Zebra mussels have inflicted tremendous damage to native ecosystems and to facilities using water, like power plants and municipal water suppliers. Millions of dollars have been spent by water users, to control and eradicate zebra mussels. And, as zebra mussel populations in an area increase, native mussels decrease; a strong indication that zebra mussels are the cause.

European green crab

These crabs invaded eastern North America in the early 1800s and were discovered in California around 1990. Green crabs probably entered the east by boats and the west in packing material of bait shipments. Females can produce an impressive 200,000 eggs annually. The European green crab eats such things as mussels, clams, snails, worms, and even other crustaceans. This diet has hurt New England’s soft shell clam industry. And, because they compete for the same food sources, they could damage commercially important Dungeness crab, oyster, and clam fisheries on the west coast.

Exotic Animals as an Invasive Species

As we have seen with the Boa Constrictors and monitor lizards in florida, the lion fish along reefs in areas not seen before, the African bee in north america, whether on land or water non resident species can have huge effects on an ecosystem.  We who have the passion for the outdoors have an obligation to continue to do our best to help prevent and fight against unnatural species being transfered to areas they were not intended to inhabit.

Recently one of our members from Texas posted a photo of an Axis Doe he had the opportunity to hunt which got us thinking.  If you love to hunt and want a distraction from the usual game is there a potential answer in Texas?  Here is what we found to tempt ones mind at a fun hunting adventure at a reasonable price should you not want to afford a hunting guide or a hunting ranch (though there are many to choose from).  

The Wildlife Management Areas (WMAs) of Texas offer a unique opportunity for the public to learn and experience the natural part of Texas and the systems that support life. WMAs are operated by the Wildlife Division of Texas Parks and Wildlife. Today, they have 49 Wildlife Management Areas, encompassing some 769,242 acres of land. WMAs are established to represent habitats and wildlife populations typical of each ecological region of Texas. Today, nearly every ecological region in the state is represented, with the exception of the Cross Timbers and Prairies in north-central Texas.
