Free
access by humans to occupied bear habitat increases the
chance of contact between man and bear. These contacts may
lead to the harassment or destruction of bears under certain
conditions. Managing the area and timing of access to bear
habitat is one strategy for minimizing this occurrence.
On
most privately owned land with black bear habitat, some type
of access management program has already been implemented by
the landowners or their lessees. For example, most
properties are legally posted and patrolled to prevent
trespass by unauthorized individuals. In some cases, access
points to private property are controlled with a system of
locked gates and limited-use roads. Access to abandoned
roads is often further restricted with gates and other
barriers such as trenches, mounded dirt, and felled trees.
Landowners wanting to develop an access management plan for
their property can use these same techniques to their
advantage.
Access
to publicly owned properties is usually addressed in
operational plans developed by the responsible
land-management agency. Each agency abides by its own set of
policies and regulations, such as limitations on the use of
off-road or all-terrain vehicles. Therefore, each should
review its access management plans to determine how these
can be adapted to maximize benefits to bears. Agencies
should also develop and implement appropriate access
management plans if none currently exist.
Bears
are often killed by motor vehicles as the animals cross
highways, especially on roads that traverse travel corridors
historically used by bears. Highway and natural resource
management agencies should work to identify these corridors
and install overpasses or culverts under roadbeds. Drift
fences can direct bears to culvert entrances and facilitate
movement beneath the roadbed. In addition, management of
vegetative cover can help reduce bear-vehicle collisions.
Crossings
may be reduced through removing vegetative cover from
roadsides at more dangerous areas and increasing vegetative
cover around underpasses to encourage use of these areas.
Collisions between bears and vehicles may
also result in human injury or death. Some accidents could
possibly be avoided if drivers were educated about the
potential for bears to cross in particular areas.
Informational billboards and brochures, bear crossing signs
and reduced speed limits at appropriate locations could be
used to alert drivers to the potential presence of bears
along certain highways. |
