DRAFT
Dear Maplewood Residents,
Background information on the Dog Exercise Area Issue:
The Maplewood Parks Commission has received many requests over the past several
years for an off-leash dog exercise area and has been working to find a way to address
the needs of the community. A group of University of Minnesota students did a survey
of people concerning Parks as part of a Capstone project that they did for Maplewood.
The survey revealed that the Four Seasons Park neighborhood was one of the areas in
Maplewood that people were requesting and could potentially support a dog exercise
area.
The Maplewood Parks Commission set up a subcommittee that looked at dog exercise
areas throughout the Twin Cities to see what worked and how they were designed.
They also looked at many different locations in the City of Maplewood. After many
months of work, the committee is recommending a trial run for a Dog Exercise Area in
the Four Season’s Hockey Rink. This Dog Exercise Area would be done on a trial basis
and only be open when the rink is not being used for skating in the winter.
Meeting Information:
th
The neighborhood meeting is scheduled for Wednesday, April 20in the Maplewood
City Hall Council Chambers and will be a part of our regular Parks and Recreation
Commission Meeting that begins at 6:30pm. There will be a brief presentation on the
proposed dog exercise area after which we will open things up for discussion.
If you have questions or concerns, please call the Parks and Recreation Department at
651-249-2007. We hope to see you there!

MEMORANDUM
TO: Parks and Recreation Commission
FROM: Ginny Gaynor, Natural Resources Coordinator
SUBJECT: Emerald Ash Borer Plan
DATE: March 9, 2011 for March 16, 2011 Commission Meeting
INTRODUCTION
In Spring 2009, Emerald Ash Borer (EAB) was discovered in St. Paul, Minnesota. Communities
throughout Minnesota are developing plans to manage this pest. In Fall 2010, Maplewood City
Forester presented information on EAB to the Parks and Recreation Commission and gathered
commissioners’ input for managing EAB in Maplewood parks. At the March 16, 2011 meeting,
commissioners will review the proposed EAB plan.
DISCUSSION
Emerald ash borer is a non-native beetle that causes widespread decline and death of ash trees.
The larval stage of EAB feeds on the tissue between the bark and the sapwood, disrupting the
transport of nutrients and water in the tree. EAB has destroyed millions of ash trees in other states.
In 2009, EAB was found in St. Paul, MN. Since then communities have been developing plans to
respond to EAB infestation. At the October 20, 2010 Parks Commission meeting, the city’s
contracted forester, Andy Hovland, presented background information on EAB and gathered input
from commissioners.
Mr. Hovland and city staff have prepared a draft EAB plan (Attachment 1). The plan recommends
using a combination of management strategies including inventory, inspection, strategic removal,
possible use of insecticide and biological control. At the March 16 meeting, commissioners will
discuss the plan and make recommendations. In particular, we ask commissioners to consider the
following:
1. Do you support pre-emptive removal of park ash trees based on health? (page 3)
2. Do you support pre-emptive removal based on area? (page 3)
3. Do you support the use of insecticides on park ash trees? (page 4 and 5)
4. Is there anything you disagree with in the plan?
5. Is there anything missing from the plan?
The Environmental and Natural Resources Commission will review the proposed plan at their March
21, 2011 meeting. Staff will present the proposal to city council in April or May 2011.
RECOMMENDATION
Staff requests that the Parks and Recreation Commission provides input and recommendations on
the proposed Emerald Ash Borer Management Plan.

Appendix D: Biological Control
The following text is from the Minnesota Department of Agriculture website, 3/4/11:
Biological control (biocontrol) is the best option for cost-effective, long-term EAB population reduction. A
variety of insecticides are available to treat individual, high-value ash trees. Cost and logistical
considerations make these treatments impractical on a large scale. Biocontrol, already used successfully to
fight some weed and insect pests in Minnesota, is considered the only feasible large-scale tool for combating
EAB. Biocontrol reunites a target pest with the insects or diseases that control the pest in its native range. In
this case, tiny, stingless wasps that control EAB in Asia are released to reduce EAB damage. Prior to their
use, biocontrol organisms are thoroughly tested to ensure they will not harm humans, native plant and
animal species, or the environment.
USDA rears three species of wasps as biocontrol agents for EAB. Two species kill EAB larvae. Tetrastichus
planipennisiadults find and insert their eggs into EAB larvae. Spathius agrili behaves similarly except that
the wasp eggs and developing wasps are attached to the outside of the EAB larvae. The developing wasps
feed on and eventually kill the EAB larvae. Egg parasitoid, Oobius agrili, adults insert their eggs into EAB
eggs on ash bark. The developing wasps feed on and destroy the eggs.
