asm for plantation forestry. How-
ever, the need for plantation
forestry within municipal areas,
under synonyms such as urban
forestry, environmental forestry,
sustainable forestry and multiple
use, is self-evident. There is the
need to protect watersheds, nat-
ural habitats, aesthetic land-
scapes as weil as provide recre-
ational areas, fuel wood, timber-
all of which generate employ-
ment directly and indirectly.
There are many traditional, quasi-
commercial silvicultural systems
that have been practised with
success for centuries in densely
populated countries. Principal
among them is shelterwood silvi-
culturewhich may be well suited
to plantation forestry within
municipal boundaries.
Shelterwood silviculture de-
scribes unobtrusive silvicultural
systems that can produce a virtu-
ally perpetual source of wood
while preserving the integrity of
the forest landscape. From a
purely productive standpoint, the
main advantage of shelterwood
systems is that they are a good
foundation upon which to estab-
lish a long-term program to refur-
bish forests in denuded areas.
PART 8: CULTIVATED TREES
There is, unfortunately, a dicho-
tomy between forestry and
arboriculture. In the context of
tree planting the dichotomy is
artificial because the skills re-
quired for one specialty are com-
plimentary to the other. One
need not look any further than
the wide-range planting habits of
the Boy Scouts of Canada. The
Scouts make no distinction as to
whether their tree planting is in a
forestry or arboricultural context.
A more salient reason for closely
linking Forestry and arboriculture
has to do with the fact that:
a) forestry concentrates on a very
small number of tree species

usually for one purpose in mind;
whereas b) arboriculure is much
more eclectic in its choice and
use of not only broad range of
tree species but also an even
wider range of shrubs.
This provides an insight into
the broad range of tree species
cultivated on the Avalon Penin-
sula and how they fit into the
urban landscape. What is more
important, the potential of cer-
tain species and how they are
mixed in a landscaping context
can be adapted to plantation
forestry, for energy conservation,
environmental protection and
aesthetics in the context shelter-
wood silviculture as part of an
overall municipal forest manage-
ment plan.
