It’s National Invasive Species Awareness Week, February 22-28

National Invasive Species Awareness Week is being celebrated this week, February 22-28, 2015. Invasive species come in many forms—plants, animals, pathogens—and are found in all types of habitats—rivers, lakes, fields, forests, urban environments, yards, oceans, and so on.

UNH Cooperative Extension’s Forestry and Wildlife Program focuses a great deal of time and effort on educating landowners and communities about invasive species, and helping them figure out how to manage invasive species. Emerald ash borer, hemlock woolly adelgid, buckthorn, garlic mustard and burning bush are just some of the invasives that we deal with every day.

Everyone can play a role in managing invasive species. Here are some ways you can help.

A Post-Presentation Press Release Means Even More Promotion!

Kamal Nath (CC2006), a Speaking for Wildlife volunteer in Carroll County, recently presented the new SFW presentation - NHBugs: The Big Three - at the Effingham Public Library. A very engaged audience of 8 individuals attended the presentation, but even more were made aware of these invasive insects and the Speaking for Wildlife program, in general, when Kamal sent a post-presentation press release to be published in the Carroll County Independent. Kamal passed along a copy of his press release, so that we can all get an idea of how to continue to spread the word about Speaking for Wildlife, even after the presentation itself is over. Kamal also noted that newspapers like at least one picture to print along with whatever story and news you're sending their way. Thanks, Kamal!



There’s a shrub growing in a nearby field that has multiple stems coming from the base and red berries that birds seem to love. What is it and where can I get one for my yard?

Autumn Olive

Q. There’s a shrub growing in a nearby field that has multiple stems coming from the base and red berries that birds seem to love. What is it and where can I get one for my yard?

A. The plant in your photo, autumn olive, is indeed beautiful, but it’s also on New Hampshire’s invasive species list and therefore not available for sale. Autumn olive has escaped from cultivations and is progressively invading natural areas. It’s a particular threat to open and semi-open areas.

A Boon for Lowbush Blueberries

Long before Europeans settled in what is now northern New England, wild blueberries offered delicious, seasonal nourishment to Native Americans. Today, 20 percent of North America’s wild blueberry crop is grown in Maine, earning producers $69 million in 2012.

New Hampshire’s wild blueberry crop may pale beside that of its neighbor, but some New Hampshirites see a sunny future for Vaccinium myrilloides in the Granite State. Farmers from Eaton and Milton, towns that border Maine, have teamed up with UNH Cooperative Extension to promote the crop by first finding a better way to deal with its arch nemesis—a determined weed called Little Bluestem.

Attack of the Parasitic Wasps: Controlling Emerald Ash Borer with Natural Predators

On a cool, dreary, late May afternoon (the temperature in Concord was 48 degrees), eight hardy souls from the New Hampshire Division of Forests and Lands, UNH Cooperative Extension, and the New Hampshire Department of Agriculture, Markets & Food could be seen traipsing through a stand of ash trees in south Concord. Their mission? To deploy eight six-inch bolts containing parasitic wasp larvae. Their target? Agrilus planipennis…emerald ash borer.

New App to Zap Greenhouse Diseases

Greenhouse growers across New Hampshire have a new digital friend in an application designed by UNH Cooperative Extension’s Cheryl Smith and Brian Krug that will help in the fight against plant diseases.

The Greenhouse Disease Control Guide offers a very simple service: Using a pull-down menu, a grower selects the disease affecting his or her greenhouse crops from a list of the 15 most common disorders. The app then provides a list of the fungicides appropriate for fighting that disease.

Invaders from the East
