awareness of the need for good vegetation management"many sections of the
northeast and especially the midwest have still to recognize and employ ecologically
sound techniques.
SUMMARY
1) On a 15001 easement crossing the Connecticut Arboretum a right-of-way
demonstration area has been established exhibiting sound vegetation
managementprinciples.
2) A seleotive approach is recommendedinvolving the removal of only undesirable
vegetation, thereby preserving low shrub and herbaceous cover
direoUy under the lines and taller shrubs and low-growing trees along
both sides,
3) Over forty spray plots have been established using various teohniques
and employing knapsack as well as comercial power spr'ayers.
4) The basal .. root collar, and stump teohniques result in the most effective
root-kill and are most selective, These are highly recommendedfor use
in right-of-Way management.
5) Stem-foliar app1ioations result in a higher percentage of resurge
especially when more resistant species are present. It is also the
least selective of techniques employed. This technique should be used
only where other more selective treatments are not feasible.
6) Possible faotors relating to species susceptibility are discussed.
7) Along with the many conservation values derived from this selective
approach, the shrub borders preserved appear relatively stable with no
apparent tree invasion after seven years, In contrast, tree invasion
is conspicuous where shrub cover has been reduced.
