From: Lloyd A. Burkholder
Assistant Superintendent of Parks
Subject: 1972 Dutch Elm Disease Control Program Cost. '
Dutch Elm Disease is a fatal disease of elms caused by a fungus, and as yet no
cure has been found. It attacks all of our native elms and most European and
Asiatic elm species. The disease may be controlled only in the sense that it's
toll may be limited, and only within limited areas requiring substantial efforts
on the part of the local residents.
Elm population surveys in St. Paul show there are approximately 56,000 boulevard
elms ; 26,000 yard elms ; and an estimated 30,000 wild elms - a total of 117,000
� elm trees within the disease control area (55.44 square miles).
Since advent of the disease in St. Paul in 1961 , the city has had 786 confirmed
cases of Dutch elm disease. Approximately 50� of these have been wild elms. These
786 diseased elms represent .6 of 1� of the total elm population in St. Paul .
f�•1any cities that failed to initiate and carry out control programs have experienced
losses of 70% to 90% of their elm population over a similar period of time.
Des t�loines, Iowa for instance, has reported the loss of over 140,000 elm trees at
a cost of 13 (plus) million dollars to it's people. ,
St. Paul cannot escape the disease, but the control programs we have to this date
have kept us from suffering the ravages that the disease has caused in other cities
ti�roughout the country.
St. Paul 's Dutch elm disease control program as such, is designed to hold their
increased elm losses from reaching epidemic proportions, and allow for a controlled
transition of elms to a more diversified planting of other species. The program
must be flexible and offer alternatives to meet the differing needs within the
control area.
' Uu.�ch t I rn Di sease �'rogram Cost
In the past 4 years alone, St. Paul has removed 2,0:47 diseased, dead, or unhealthy
boulevard elm trees without replacing a single tree. Tree planting is now looked
upon as a part of a Dutch elm disease control program. Diversified tree planting
is an important factor in preventing epidemic disease and insect invasions within
a comnunity. A City's boulevard and park trees are an indispensable part of it's
environment and every effort must be made to preserve and enlarge this necessary
element for City living.
New methods of control are being tested and are reported from time to time in
various publications , as though the elm problem has been solved. However as of
no�v, the only proven and practical method of control is the same method we have
been using - intensified to meet our present situation. This includes prompt
detection and removal of diseased trees; elimination of all possible beetle
breeding material ; use of root graft controls where necessary; and the planting of
diversified tree species to provide the proper distribution of a variety of trees
in the community. Hopefully, research will provide several practical techniques
that, in the future, will be used singly or in combination for a safe, integrated
control program.
