Comments sought on state invasive species management plan

(Released by Minnesota DNR on September 3, 2009)

A draft Minnesota Statewide Invasive Species Management Plan (PDF) is now available for public review and comment until Sept. 22.

The plan was developed by the Minnesota Invasive Species Advisory Council, co-chaired by the Minnesota’s departments of Natural Resources (DNR) and Agriculture.

It is designed to provide a framework for addressing both aquatic and terrestrial invasive species issues in Minnesota.

The plan includes strategies and actions to address the main issues related to invasive species: prevention of new introductions into the state; early detection and rapid response to new introductions; containment of populations; and management of established populations to reduce their harm.

This draft plan reflects several years of work by many organizations from the local, state and federal government levels and a number of nongovernmental organizations.

“It will be a good framework for addressing the invasive species issue,” said Jay Rendall, DNR invasive species prevention coordinator. “However, we want to have more input on strategies and actions that could be taken in the future.”

Comments from individuals and organizations will be used to refine and expand the actions identified in the draft plan. When completed, the plan will also provide opportunities for improved coordination and partnerships between federal, state and local governments, tribes, conservation organizations and others working to minimize the impacts caused by invasive species in the state.

The draft plan and information about submitting comments is available on the DNR Web site. Printed copies can be requested by calling 651-259-5100. Written comments can be submitted in writing to Invasive Species Program, Minnesota DNR, 500 Lafayette Road, St. Paul, MN 55155, or by e-mail.

Just wanted to let you know about a new tree resource. With the help of Cyndy Ash Kanner, and reviews from Joe O’Brien of the USDA Forest Service and Jim Walla of NDSU, we now have a new publication on diseases of spruce trees including photos, id info, biology and management. The spruce diagnostic tool will be coming soon and will link directly to this pub for management info.

Emerald ash borer discovered in St Paul, MN

The Minnesota Department of Agriculture has announced that EAB has been discovered in St Paul, Minnesota.  There’s a news conference at 3:30 today at Hampden Park in St Paul.  (via @mnagriculture on Twitter).  We’ll provide updates as we’re able.

Extension’s EAB page has links to help Minnesota landowners and citizens prepare for EAB.

Update: MDA has a press release on the Minnesota EAB discovery here.

EAB discovery prompts Houston County ash quarantine

On April 22, the Minnesota Dept. of Agriculture announced a state quarantine on firewood, ash trees, and ash tree products in Houston County. The precautionary measure is designed to prevent the spread of emerald ash borer, a highly destructive tree pest recently discovered just across the Mississippi River from Houston County. Read the full announcement here.

MDA and DNR officials urge all Minnesota citizens to take several steps to help keep EAB from spreading:

  • Don’t transport firewood, even within Minnesota. Don’t bring firewood along on a camping trip.
  • Don’t buy or move firewood from outside Minnesota.
  • Watch for signs of infestation in your ash trees. If you suspect your ash tree could be infested by EAB, visit www.mda.state.mn.us/plants/pestmanagement/eab.htm and use the “Do I Have Emerald Ash Borer?” (PDF) checklist on the MDA’s EAB web page.

For more on the recent discovery, see the announcement and many links in our April 7 post: EAB discovered in Wisconsin, a mile from Minnesota.

EAB discovered in Wisconsin, a mile from Minnesota

The following information was sent out by the Minnesota Department of Agriculture (MDA) on April 7.  We’re developing information to help Minnesota woodland owners plan for the expected widespread ash mortality. Meantime, see the many links below and post your thoughts here or on the discussion board.

Emerald ash borer (EAB) has been discovered in Victory, Wisconsin. Victory is approximately 1 mile south of the Minnesota border along the Mississippi River.

This discovery was made only last week and confirmation was made on Monday, April 6. The Wisconsin Departments of Agriculture and Natural Resources have released the news of this find today, April 7. Although Wisconsin has not had much opportunity to evaluate the scale of this infestation, their initial assessment was that this was a significant infestation.

Due to the proximity of this infestation to Minnesota and Iowa, it is possible that the infestation extends into one or both states. The Minnesota Department of Agriculture, along with our partners at the Department of Natural Resources, USDA APHIS Plant Protection and Quarantine and USDA Forest Service are already investigating the southeastern portion of Houston County to determine if the infestation extends into Minnesota. We expect these initial surveys to last up to four weeks. If emerald ash borer is found in Minnesota, we will activate our EAB Response Plan (PDF).

Whether or not this initial round of survey discovers EAB in Minnesota, we will be intensifying survey and outreach efforts in southeastern Minnesota during 2009.

The complete press release that is being issued in Minnesota is here. Some key points to remember about the situation are:

  1. EAB has not yet been found in Minnesota, but state and federal authorities are investigating the area.
  2. No quarantines have been established in Minnesota. A federal quarantine will be imposed in Wisconsin on the infested area.
  3. At this time we are asking the public to voluntarily not move ash wood out of Houston County. A quarantine could be placed on Houston County by Minnesota Department of Agriculture in the coming weeks.
  4. For Minnesota beyond Houston County the situation has not changed. People should be vigilant as to the condition of their trees and report suspected infestations to MDA. Movement of untreated firewood over long distances should be avoided in any part of the state.

If you have questions, please direct them to MDA’s Arrest the Pest hotline.

“Arrest the Pest” Hotline:  651-201-6684 – Metro Area or 1-888-545-6684 – Greater Minnesota. Or email Arrest.The.Pest@state.mn.us.
