Ontario
Forest

(NWO
FEC)
has
provided
a
tool
for
boreal
forest
site
classification.
Unfortunately
its
Held
application
requires
considerable
expertise
and
frequent
referral
to
field
manuals
for
determination
o
soil
properties
and
identification
of
species
of
trees,
shrubs,
herbs,
mosses,
and
lichens.
An

Expert
systems
have been
used
in
many
fields,
including
medicine,
engineering,
agriculture,
and
forestry.
The
NWO
FFCis
essentially
a
well
defined
diagnostic
tool
requiring
the
user
to
determine
certain
soil
and
vegetation
characteristics
,n
order
to
classify
them
into
specifically
defined
groups.
This
makes
it
suitable
for
automation
using
expert
system
principles.
FEXPERT
is
designed
to
facilitate
the
application
of
the
NWO
FEC
system
by
computerizing
the
essential
contents
of
its
field
manuals
and
classification

so
that
the
user
may
have
immediate
access
to
the
necessary
information
lor
quick
consistent,
and
accurate
classification.
FEXPERT
should
prove
valuable
to
,he
novice
by
providing
extensive
help
in
the
form
of
text,
diagrams,
pictures,
profiles,
etc.,
for
proper
classification.
