AGENDA ITEM: X. B. Tree Inspector Report
TO: Advisory Parks Commission
PREPARED BY: Gregg Hove, City Forester
BACKGROUND/HISTORY:
The primary responsibilities of the seasonal tree inspector include coordinating the shade tree disease
program, administering the buckthorn removal assistance program, responding to customer concerns and
general questions, participating in public education initiatives, and assisting with forestry staff projects.
During the 2013 season, the tree inspector responded to 161 customer requests for site visits, detected
489 diseased trees, and coordinated 227 buckthorn pickups. Following is the 2013 tree inspector report
which details the progress of the shade tree disease program, buckthorn assistance program, and other
emerging issues of concern such as two-lined chestnut borer and emerald ash borer.
2013 TREE INSPECTOR REPORT
The City of Eagan shade tree disease program has been administered by the Parks and Recreation
Department Forestry Division since the early 1970’s and was originally established as a response to Dutch
elm disease. Now, the program includes the detection and management of oak wilt as well as Dutch elm
disease and is enforced by City of Eagan ordinance Sec.10.20 (Shade tree disease control and prevention).
Through this program, the City of Eagan strives to suppress devastating shade tree diseases in order to
maintain the valuable urban forests and natural landscapes that enhance the quality of life for people in the
City of Eagan.
The most effective strategy for managing shade tree diseases is through prevention. In the City of Eagan,
promoting the prevention of further spread of Dutch elm disease and oak wilt is only possible through
effective detection, public education, and execution of control methods.
The City of Eagan forestry staff work diligently to detect most of the Dutch elm disease and oak wilt on public
and private property. The City must also rely on private property owners and residents to help in detection;
therefore, educating and engaging residents is imperative. Opportunities to educate the public about shade
tree diseases include everyday direct contact with Eagan residents, the City of Eagan website, newsletters
and other publications, school visits by the City Forester, Arbor Day, Be Green Eagan Night at Market Fest,
and Eagan television (E-TV) broadcasts. Through these various methods of public education, residents
become aware, informed, and hopefully genuinely concerned about shade tree diseases and as a result may
take an active role in detection and control efforts.
Records are kept in yearly field notebooks and also in an ongoing Access database, recording Dutch elm
disease and oak wilt infected trees on both public and private property. The following statistics are based on
the collected data.

Advisory Parks Commission January 16, 2014 Page 8
DUTCH ELM DISEASE
Dutch elm disease is a vascular wilt that grows in the cambium of most elm trees, resulting in a wilt that
eventually kills the host tree. American elms have a low resistance and are the most susceptible to Dutch
elm disease, rock and slippery (red) elms have moderate resistance, and Siberian elms have high
resistance.
The fungus can spread in two ways – overland and underground. The overland, or aerial, spread is most
common and requires a vector. The vectors are native and European elm bark beetles. The beetles breed
in/on diseased elms which are dying or already dead and pick up Dutch elm disease fungus spores. The
beetles fly to healthy elms to feed, and in the process deposit the Dutch elm disease fungus spores.
Underground spread of Dutch elm disease is not as common and occurs through shared root systems of
elms in close proximity.
The most widely employed method used to control Dutch elm disease is sanitation, which the City of Eagan
promotes and utilizes. Sanitation involves the removal and proper disposal of infected dying and dead elm
trees which reduces beetle populations and sources of the fungus.
Under the sanitation method, once a tree is detected with Dutch elm disease, the City of Eagan requires the
property owner to remove and properly disposed of the tree within 20 days of official notification. Early
detection is critical as the first step in the removal process.
2013 Dutch Elm Disease Detection Data
During the 2013 season, a total of 287 Dutch elm disease infected trees were detected in the City of Eagan.
The tree inspector detected 265 (92% of the total amount) Dutch elm disease infected trees across 153
locations, or infection centers, located on both private and public property. The City of Eagan forestry staff
detected 22 (8% of the total amount) Dutch elm disease infected trees in 7 Eagan parks.
Compared to 2012, both the number of detected trees and the amount of infection centers decreased.
However, the annual difference in the number of detected trees and infection centers is dependent upon
many factors (such as recording methods, seasonal change in tree inspector, the amount of residents
engaged in detection, and environmental fluctuations) and should not be considered the true trend of the
spread of Dutch elm disease in the City of Eagan but rather an indicator of progress in detection.
The total amount of detected Dutch elm disease infected trees from 1997-2013 is 5,193 with an annual
average of 305 (fig. 2). The total amount of detected Dutch elm disease infection centers from 1997-2013
is 1,490 with an annual average of 88 (fig. 1). Also, the overall average number of infected trees per
infection center from 1997-2013 is 3.49 trees.

OAK WILT
Oak wilt is a tree disease caused by the fungus Ceratocystis fagacearum and has the potential to infect and
eventually lead to the death of all oak species present in the City of Eagan. Oaks in the red oak family,

including northern red and northern pin oaks, have a much lower resistance to oak wilt than oaks in the
white oak family, including bur and white oaks.
The fungus can spread in two ways – overland and underground. The overland, or aerial, spread requires a
vector. The vectors are sap beetles in the Nitidulidae Family. These beetles visit wounds on both infected
and healthy oak trees; collecting and depositing oak wilt fungus spores in the process. Underground spread
is common and occurs through shared root systems. Oaks of similar species and in close proximity often
share common root systems. Most new oak wilt infections are caused by the passing of the fungus from the
sap beetles; expanding infection centers through grafted roots.
Currently, there are four ways to control and prevent oak wilt. First is through sanitation which helps prevent
overland spread of oak wilt and involves the removal and proper disposal of infected trees that may produce
oak wilt spores. Second is by pruning oaks only during the months of November through March. Not
pruning or wounding oaks during the high and low risk periods (April-October) reduces the possibility of
introduction of the fungus by active vectors onto healthy oaks and helps prevent overland spread of oak wilt.
The third way is through mechanical/physical barriers – mechanical barriers (such as a vibratory plow) sever
root connections between infected and healthy trees and in effect helps prevent the common underground
spread of oak wilt. The fourth method is through chemical barriers which can help prevent both the overland
and underground spread of oak wilt. Chemical barriers, such as systemic injections of Propiconazole, can
act as a treatment for early infected white oaks, and as a prophylactic against the oak wilt fungus for both
red and white oaks.
The City of Eagan forestry staff has employed all four methods of control and prevention on various public
properties throughout Eagan over the years. The method, or methods, employed at each site has been
dependant on time of detection, location and quality of tree(s)/site, and availability of resources.
To help Eagan residents with the costs associated with oak wilt, the City of Eagan implemented the oak wilt
suppression cost share program. The program offers some financial assistance and monetary incentive to
encourage Eagan property owners to help in the control and prevention of oak wilt in Eagan.
2013 Oak Wilt Detection Data
During the 2013 season, a total of 224 oak trees across 115 locations, or infection centers, in the City of
Eagan were detected as being infected with oak wilt. Of the 224 trees, 221 (99%) were in the red oak family
and 3 (1%) were in the white oak family. Compared to 2012, the number of detected trees and infection
centers increased incrementally. However, the annual difference in the number of detected trees and
infection centers is dependent upon many factors (such as recording methods, seasonal change in tree
inspector, the amount of residents engaged in detection, and environmental fluctuations). A midsummer
wind storm was a contributing factor in the Oak Wilt losses in 2013.
The total amount of detected oak wilt infected trees from 1997-2013 is 2,585 and an annual average of
152 (fig. 3). The total amount of detected oak wilt infection centers from 1997-2013 is 1,241 with an
annual average of 73 (fig. 4). Also, the average number of infected trees per infection center from 1997-
2013 is 2.08 trees.

Oak Wilt Suppression Cost Share Program
In an effort to provide some support to property owners in the often costly management of oak wilt, the City
of Eagan allocated a $7,000 budget toward the oak wilt suppression cost share program for the 2013 fiscal
year. Residents are reimbursed on a first come first served basis, and applications for cost share
reimbursement submitted after current funds are depleted are carried over to the next year. Because of the
overwhelming participation of oak wilt management by private property landowners, and subsequent
requests for cost share funds, $5,000 was added (from the tree mitigation fund) to the forestry budget in
October 2013 to fulfill current oak wilt cost share requests.
Through this program, property owners may be eligible to receive up to 25% ($500.00 maximum)
reimbursement for each treatment action that may have been recommended or required by the City of
Eagan, such as root graft disruption (vibratory plowing), fungicide injection, or removal of potential spore
producing red oak trees.
In 2013, fifty-two Eagan property owners requested cost share reimbursement and together had spent a
total of $50,212 toward either one or more oak wilt control methods (fig.5). The City of Eagan paid out
$11,872 in cost share eligible expenses (25%).
Most of the total amount spent by property owners was spent on fungicide injections and tree removal.
The total amount that has been reimbursed by the City to Eagan to property owners from 2001-2013 is
$77,967 (fig.6).

BUCKTHORN REMOVAL ASSISTANCE PROGRAM
Common or European buckthorn, and glossy buckthorn are two non-native invasive buckthorn species found
in the City of Eagan. European buckthorn was first brought to Minnesota from Europe in the mid-1800s as a
very popular hedging material. It has since become a nuisance plant that is threatening the vitality of
Eagan’s native landscapes, forming dense thickets in forests, yards, parks, and roadsides crowding out and
displacing native plants, shrubs and small trees.
The Buckthorn Removal Assistance Program (BRAP) was implemented in 2001 to encourage and assist
residential private property owners in the control of buckthorn on their own properties. The program is
offered at no cost to Eagan property owners and involves the City of Eagan forestry staff regularly picking up
and chipping buckthorn that has been cut and collected by program participants.
The program is popular and continues to see an increase in the number of new participants each year. In
2013, the tree inspector enrolled 70 new participants in the program making a grand total of 782
participant households in the program.
To be considered a participant in BRAP, property owners must complete a brief onetime site visit with the
City of Eagan tree inspector. During the site visit, the property owner and tree inspector identify and discuss
buckthorn and buckthorn control on the property and designate an area on the property where the
buckthorn will be picked up in the future. Once the property owner is considered a BRAP participant they
can contact the City and request pickups as needed throughout each season. The City of Eagan Forestry
Division dedicates each and every Monday during the months of May through November to accomplish the
buckthorn pickups.
As of November 22, 2013, the tree inspector conducted a total of 70 site visits and forestry staff completed
227 pickups, and approximately 212 cubic yards of buckthorn were chipped. Site visits and pickups ended
in mid November.
Lastly, it’s important to note that the City recovers some of the minor costs of administering BRAP. Chipped
buckthorn is collected and stored by the City for one year then it is used as mulch at various sites around the
City. As a result the City receives cost savings toward the expense of otherwise purchasing commercial
mulch products.
Emerging Shade Tree Issues of Concern in the City of Eagan
EMERALD ASH BORER
Emerald Ash Borer, a non-native invasive beetle, was discovered for the first time in Minnesota on May 13,
2009 near University and Raymond Avenues in St. Paul. Subsequent to this confirmed location; EAB has
been found in the Summitt neighborhood of St. Paul, Shorewood, and Winona and Houston Counties. This
summer was relatively quiet; one new site was reported in Superior, WI. Emerald Ash Borer (EAB) has
caused the death of millions of ash trees across Michigan, Ohio, Indiana, Illinois, Missouri, Pennsylvania,
Maryland, West Virginia, Virginia, Wisconsin, and now Minnesota. An infestation of EAB in Eagan could
cause extensive ash mortality throughout the City and ultimately lead to major changes in the composition
and quality of Eagan’s environment and natural landscapes.
Emerald ash borers cause the decline and death of ash trees through their tunneling activities, which are
similar to the two-lined chestnut borer. The tunneling activities under the bark hinder a tree’s ability to
transport life supporting water and nutrients. Adult beetles also feed on leaves but at this time it’s uncertain
what impact adult feeding has on tree health.
City of Eagan staff began receiving calls from concerned Eagan residents the very next day the EAB discovery
in St. Paul was announced. Since then, the tree inspector has conducted many site visits for EAB as
requested by residents and has also actively looked for and examined EAB suspect trees throughout Eagan.
So far no EAB has been detected in the City of Eagan.

City of Eagan forestry staff communicates with residents regarding EAB, creating an EAB info sheet and
webpage for the City of Eagan website.
Forestry staff has participated in workshops and meetings with other Twin City metropolitan municipalities
in an effort to stay informed and to communicate and collaborate on how to prevent, mitigate, and manage
what is considered a potential real imminent and devastating episode.
The most effective control methods for EAB are insecticide treatments and sanitation. Insecticide
treatments may be used to prevent EAB infestations, and sanitation involves the removal and proper
disposal of infested trees/wood to reduce EAB populations. In 2012, City of Eagan forestry staff completed
preventative EAB treatments with insecticide on high value ash trees located along some selected
boulevards and parks.
Conclusion
Shade tree diseases, such as Dutch elm disease and oak wilt, and invasive exotic species, such as
buckthorn and emerald ash borer, have been and will continue to be a problem that is worth managing in
the City of Eagan in order to maintain the highest quality natural resources and environment. The staff and
programs currently in place in Eagan work to educate and involve the public, and help to suppress the affect
of shade tree diseases and invasive exotic species on the City and its residents.
