Control Privet in Mature Hardwood Stands

"Chinese Privet (Ligustrum sinense) is one of the most widespread non-native invasive plants within hardwood and pine forests throughout all ecoregions of Georgia (Harper 2009). It aggressively invades, spreads and eventually dominates many forested understories, completely displacing native flora. This field trial by the Georgia Forestry Commission evaluated one technique (previously untested) for removing a privet-choked understory in a hardwood bottom within the piedmont region."Click here to read the paper.

Spreading the Right Messages About Invasives

Excerpt from article in Diversity and Distributions invasive bush "honeysuckle disproportionately impacts birds of conservation concern and acts as an ecological trap even for generalist species. Although there is a real need to fully consider both positive and negative consequences of invasive species, if such research is not placed within the proper ecological context, we risk sending distorted or mixed messages to managers."

What Is in Your Backyard?

What is in your backyard?

Do you know how many different kinds

 of invasive plants are lurking in your yard? 

Here is a way to find out:

1. First find the list of invasive plants for your state or region. Click on this link to the National Exotic Pest Plant Council, then choose the EPPC in your region to find your list. It could also be called an Invasive Pest Council or something similar.

2. Next click on this link to EDDMapS and choose your county to get a list of the non-native plants which have been reported in your county. Please note that all of the species listed may not be a problem in your county, but are exotic to the U.S. and are listed as a problem somewhere in the U.S.

3. Take the two lists and a highlighter and walk around your yard. Highlight every plant on the lists that you find in your yard.

4. Let's see what everyone finds. Show us your results on the Bugwood Facebook page.

If you need help to check that a plant on the list is what are you seeing in your yard...go to www.Invasive.org. Click on the Plants tab then find the plant you want to check out from the 1576 plants listed there. Click on the plant name and you can see basic information, management information and pictures of the plant which you can compare to the plant you have in your yard.

6th Annual Southeastern Bioenergy Conference

The 6th Annual Southeastern Bioenergy Conference will be held in Tifton on August 9-11. This is a great opportunity to meet the key players and learn what is going on.  

This Conference is really hard to beat for content and impossible to beat for value. This year, NASCAR driver Kenny Wallace will help kick the Conference off, followed by a group of Bioenergy experts from Europe, China, Brazil and the U. S. Innovative research, financial support, regulatory oversight, and long-term renewable fuels contracts will be the subject of our speakers from DOE, USDA, EPA and the Air Force.   

As with last year, Dr. Craig Kvien, the conference organizer, we will cover the registration for County Extension personnel. But please register so they will have a good count for meals.

Texas Invasive Plant and Pest Conference

Announcing the 2011 Texas Invasive Plant and Pest Conference

November 8-10, 2011

The Lady Bird Johnson Wildflower Center

Austin, Texas 

This November, the Texas Invasive Plant & Pest Council will be hosting the fourth statewide conference on invasive species at Lady Bird Johnson Wildflower Center in Austin, Texas. Building off the 2005, 2007 and 2009 conferences, the 2011 conference will be a professional level meeting including keynotes, concurrent sessions, posters, field trips and symposia. 

This conference is designed to serve scientists, land managers, state and federal agencies, local governments, the green industry and other stakeholders interested in invasive species issues in the state of Texas.

To learn more about the Conference Program, Call for Papers, Abstract Submission, or Sponsors and Exhibitors, visit the 2011 Conference Website at http://texasinvasives.org/professionals/conference11.php.

Nonnative Invasive Plants of Pacific Coast Forests

A recent press release: The Pacific Northwest Research Station/U.S. Forest Service recently released, Nonnative Invasive Plants of Pacific Coast Forests: A Field Guide for Identification.  It is a concise and well-illustrated field guide for novice botanists and managers alike.
“Nonnative plants affect the composition and function of natural and managed landscapes. They can have a large economic effect on landowners and local governments through eradication costs and lost or degraded land use,” according to lead author and Forest Service research ecologist Andrew Gray.
The 91-page color guide provides detail on each plant in nontechnical language and photos of different stages of plant development are included to allow reliable identification in the field at different times of the year. Information was synthesized from various national, regional, and state lists, assessments, and botanical guides.
“Our final list was designed to capture species believed to be most prevalent or problematic for use in strategic forest inventories like the Forest Service’s Forest Inventory and Analysis Program,” adds Gray.
Little comprehensive information exists on the abundance, distribution, and impact of nonnative plants. The lack of identification guides with sufficiently specific descriptions and detailed images makes collecting information on the impact of invasives difficult. Gray and his colleagues, Katie Barndt, an instructor at North Seattle Community College, and Sarah Reichard, professor at the University of Washington’s School of Forest Resources, designed a study to prioritize a list of nonnative invasive plants affecting forest lands in the Pacific coastal states. This field guide is the result of their study and covers California, Oregon, and Washington.

Mid-Atlantic Invasive Plant Conference

Invasive Plant Conference: Tools and Techniques
for Mapping, Managing and Mending Invaded Lands
Wednesday and Thursday, August 3 and 4

National Conservation Training Center, Shepherdstown, West Virginia

The eighth Mid-Atlantic conference will provide you with the tools you need to accomplish your invasive plant management objectives. You will learn how to map the invasive species on your site, develop a site plan, select appropriate control methods, and ultimately, achieve restoration to a site dominated by suitable native plant species.
