Tips for Battling Minnesota's Invasives

If we’re not careful, harmful insects and plants could leave scars on Minnesota’s environment. Here is some information from the Minnesota Department of Agriculture.

What is an invasive species? According to scientists, an invasive species is an organism (animal, insect, plant, pathogen, etc.) that is not native to a specific location and causes great harm to people and the environment because of the lack of natural controls in the new environment.

Smart Phone App Fights Invasives

A Michigan State University scientist has developed a smart phone application to help keep track of invasive species.

The free app is part of the Midwest Invasive Species Information Network developed by bio-geographer Amos Ziegler.

It enables people who think they’ve spotted an invasive critter or plant to photograph it with their phone, make some notes and alert state officials and scientists.

Ziegler says information such as the location, date and time of a sighting can help experts map the spread of unwanted species and develop  plans to stop them.

The 12 Worst Invasives in the United States

For some animals, there’s no such thing as a dog-eat-dog world. They rule.

Animals from around the world that stow away in airplanes, ships and the luggage of some smuggler become almost bulletproof when they make their way into the American wilderness as invasive species. Why? They’re new here, and they don’t have predators to keep them in check. Animals that should be afraid of a vicious predator aren’t. Invasive species eat like kings.

$2.5 Million War on Beetles

Much as the Asian long-horned beetle attacked maple and elm trees on the East Coast, the coconut rhinoceros beetle could devastate Hawaii's palm trees and move on to bananas, papayas, sugar cane and other crops afterward. Adult beetles burrow into the crowns of palm trees to feed on their sap, damaging developing leaves and eventually killing the trees.

At this point, eradication is still possible. and the urgency to address the problem is both cultural and financial. 

Green Team Takes On Invasives

In the last few years, a team of Vancouver Lower Mainland residents has yanked 74,500 pounds of invasive plants out of area parks, planting in their place 7,100 native trees and shrubs.

The cost to taxpayers for all that time and effort? Absolutely nothing.

Hawaii's Invasive Species

Hawaii's isolation has made the island state home to more invasive species than anywhere else in the U.S.

Little fire ants, coconut rhinoceros beetles, albizia trees, rats, mongoose, strawberry guava, coqui frogs, miconia, fireweed and invasive algae all share one common trait.  As invasive species, they provide examples of some of the worst offenders among the many plants and animals that pose what the state legislature has declared as "the single greatest threat to Hawaii's economy, natural environment and to the health and lifestyle of Hawaii’s people."

Mountain Pine Beetle Epidemic Wanes in Colorado and Wyoming

National forest officials in Colorado and Wyoming said Monday that they plan to reopen more campgrounds and change tactics as a massive outbreak of mountain pine beetles wanes.

Workers will now turn their attention more toward removing dead trees to prevent them from exacerbating wildfires, Medicine Bow-Routt National Forest Supervisor Dennis Jaeger said. Trees killed by beetles have largely been removed from popular recreation spots and near roads.

Prune Oak Trees in Wisconsin Now to Prevent Oak Wilt

Now is a good time for tree pruning, while temperatures remain cold, according to Wisconsin Department of Natural Resources tree health experts.

“The best time to prune trees in Wisconsin is during winter when a tree is dormant,” said DNR Urban Forester Don Kissinger. This is because insects and diseases that attack open wounds on pruned trees aren’t active in winter, and without leaves on the trees it is easier to see and prune broken, cracked or hanging limbs.

Nebraska's 54 Million Ash Trees Threatened by Emerald Ash Borer

It’s not a matter of if the emerald ash borer will reach Nebraska. It’s a matter of when.

That was the message delivered Thursday as members of the city’s parks department and tree board met with University of Nebraska-Lincoln Extension Educator Kelly Feehan and Laurie Stepanek of the Nebraska Forest Service to discuss the tiny insect that’s wreaking havoc across the eastern United States.

Tests Show Wheat Gene Increases Blight Resistance of Chestnut Trees

Researchers at the U.S. Department of Energy's Oak Ridge National Laboratory (ORNL), working collaboratively with scientists funded by The American Chestnut Foundation, have helped confirm that addition of a wheat gene increases the blight resistance of American chestnut trees.
