The Utah Department of Natural Resources found an extremely invasive mussel under a dock at Utah's Sand Hallow Reservoir. State officials want the public to know that this is bad news, is very serious and the public needs to help take action to keep contamination from spreading. Mussels are ecosystem killers because they clog dams and waterways, cut people's feet when they attach to rocks and kill fish by sucking up nutrients.

Water Hyacinth is an invasive, free floating, aquatic plant that is problematic in the southeastern United States. Native to South America, the plant affects water traffic, water quality, water use, biodiversity and infrastructure for pumping and hydroelectric operations. Water Hyacinth also lowers oxygen levels which kill fish and increases populations of vectors of human and animal disease. Scientists have released an insect called Megamelus scutellaris to help control the water hyacinth. These insects feed on the sap of water hyacinth and their population increases rapidly, which will enable them to quickly impact the invasive population.

Jacob Schindler, a sixteen year old at Lowndes County High School, may have the key to breaking kudzu's long hold on Southern terrain. The junior uses helium to eradicate kudzu with a device he designed that allows him to drill into the ground with a small tank of helium and evenly distribute it to the kudzu. All of this happens without harming other plants. What started out as a science fair project when we was only in sixth grade, may have turned into an entrepreneurial endeavor that could change agriculture (and his life) forever.

Seattle's first bioblitz kicked off on Friday along the trails of Washington Park Arboretum. A bioblitz is an intense, 24 hour effort to identify as many species in an area as possible. Botanists stayed up all night identifying flora, insects, fauna, bats, spiders, eagles, salamanders, stinging ants and the list goes on. Nearly 400 species were identified on GPS devices which will become a part of the NatureMapping Program. This program attempts to chart biodiversity in the states.

Kudzu has taken over 7 million acres of land in the United States. With this huge number, scientists thought it was time to take a closer look. They found out that kudzu not only invades landscapes, but might also increase ozone pollution by more than one third in the future. What exactly does this mean? Kudzu grabs nitrogen from the air and puts it in the soil. Microbes then convert the nitrogen into nitrous oxide, which is one of the pollutants that comes from automobile exhaust. The gas escapes from the soil and into the air and undergoes reactions that lead to the creation of ozone. This could lead to more summer days with the ozone in excess of EPA standards.

Emerald Ash Borer has continued its spread into Pennsylvania and has now been detected in Bedford County. This pest has been devastating the native ash trees as it has spread from the orignial introduction in Michigan. The Pennsylvania Department of Agriculture is again urging campers not to move firewood since it is the primary way that this pest is spread. See the PA Department of Agriculture website for the full news release.
A team of scientists discovered in only a few short weeks at least a dozen new reptiles, mammals, insects, birds and amphibians in the rain forests on the island of New Guinea. Some of the new species include an imperial pigeon, a Pinocchio-like frog and the world's smallest wallaby. Many of these new animals were found in the mountain tops of the Foja mountains, whose inaccessibility has allowed species to evolve in isolation (hense the nickname: The Lost World).

An invasive species called Didemnum vexillum has been discovered along Oregon's coast. The jelly like organism can smother docks, shellfish beds, coat boat hulls, and water intakes. Native to Japan, the colonial tunicate is on the list of 100 worst invasive species to keep out of Oregon. Oregon scientists have an eradication effort planned for this summer which they hope will be successful. Click here to read more.

Scientists have developed a weed calculator to help land managers calculate the economic impact from invasive weeds on their property. For example, the calculator tells ranchers how many more cows they can raise if they eliminated one or two widespread invasive plants. This new invention is based on a computer model that utilizes data from 30 weed scientists to predict invasive plant impact on forage production. To read more on the weed calculator, click here.

In Central Florida, a Burmese python slithered underneath a woman's car in a parking lot and refused to come out. A wildlife officer was able to grab the four foot python from underneath the woman's car. The invasive species will be brought to a pet store or to someone who is licensed to have pythons.

DEET is a chemical found in most bug spray. It repels mosquitoes by mimicking plant chemicals. When female mosquitoes need to fertilize their eggs, they are on the lookout for blood not plants. Therefore, a DEET coated human does not smell like a tasty snack. Scientists have recently found DEET insensitive mosquitoes. This trait can be passed down genetically to their offspring.

The tegu lizard has four legs, sharp claws and can take down your Chihuahua. Native to South America, this invasive species has been found in South Florida and can reach three feet long. The tegu has become a problem because pet owners let them go into the wild. Scientists are trying to regulate the tegu lizard problem by putting them in zoos where they cannot do any harm.

Minnesota ranks second in the highest number of ash trees in the nation. However, an invasive species called the Emerald Ash Borer, is killing ash trees and is making its way throughout the state. This wood boring beetle is smaller than the size of a penny, but its damage is massive. The Emerald Ash Borer is one hundred percent fatal to every tree it encounters and experts worry about its spread. To read more about the Emerald Ash Borer, click here.

American farmer's use of the weed killer Roundup has led to a rapid growth of new tenacious weeds. These new weeds are Roundup resistant and to cope with the problem, farmers from all over the U.S. have to pull weeds by hand, spray more herbicides and do more labor intensive work. Experts say that such efforts could lead to lower crop yields, rising farm costs, higher food prices and more pollution to land and water. Click here to read more about the roundup resistant weeds.

Brad Elliot and his team from the Nature Conservancy are working together to root out Japanese knotweed and garlic mustard through the Winooski River floodplain forest in Richmond, Vermont. These two invasive species weaken the riverbank, lessening its ability to protect Richmond from severe flooding. The good thing about Japanese knotweed and garlic mustard is its edible and restaurants in the area use them as ingredients in their meals.

Aspen is the most widely distributed tree in North America and is also the most beautiful fall tree in the western United States. It ranges from Mexico to Newfoundland to Alaska and the states, Colorado and Utah, have the largest portion of aspen acreage in the world. However, this common tree is dying, in particular older, more mature aspens that exceed 80 years. Silviculturists do not know the exact cause of this die-back.

The Apiary Inspectors of America (AIA) and the USDA have completed the fourth annual census of winter honey bee colonies in the U.S. What they found was troubling. Thirty-three percent of all the colonies in the United States died last winter. But that's not all. Of those who completed the census, they lost over forty percent of their colonies. When looking at all the respondents to the census over the previous three years, researchers found a twenty-three percent increase in the average number of honey bees lost. The cause of this massacre...Mother Nature. Let's just hope she is a "better Mother" this season. Click here to read more about the dying honey bees.
