Recreation (R)This
survey point should be as close to the geographic center of the high-use recreation zone
as possible, even if it falls within a non-forested part of the high-use area. The
high-use recreation zone is the area that is physically modified or disturbed to
accomodate recreational activities. This zone includes all structures, roads, camping, and
picnic sites. There should be a relatively clear delineation between this zone and the
surrounding undisturbed forest. Surrounding forest areas could include low-use areas with
recreation trails. To select point R, use your judgement and look for a spot that best
represents the most highly affected section of the recreation area, but where you can
conduct the BFL protocol with as little interference as possible.
Edge (E)This survey point
should be 500 feet (150 meters) outside the edge of
the high-use zone, within relatively undisturbed forest. If the high-use recreation zone
is small, the distance between points R and E may be less than the minimum distance
between survey points as stated in the Study Site Instructions (page 2.4 of the
manual).
Control (C)This survey
point is your control. It should be at least 1,500 feet (460 meters) but not more than 5
miles (8 km) from the edge of the high-use recreation zone and should be at least 500 feet
(150 meters) from the edge of the forest patch. Note that the control point must be within
the same forest patch as E and the habitat should be as similar as possible, controlling
for factors such as hydrology, elevation, and forest type. This survey point can be a
pre-existing BFL point if it fits the above criteria.
