Section 3: Changing Attitudes
Wildlife Density and Safety
Studies suggest that roadside management practices have little
influence on roadkill. The main factors are the types and conditions
of habitats on adjacent lands and associated wildlife population densities
on those lands. Deer prefer established travel corridors. Their
movement patterns are based on the available cover and the juxtaposition
of favored habitats. A greater frequency of road crossings will
occur where a highway intersects these preferred habitats. Other
species of wildlife that typically use established corridors include
raccoons, skunks, opossums, squirrels, coyotes, bobcats and some
songbirds. These animals are likewise vulnerable to roadkill. Road
crossings at creek and river drainages are good examples of this
relationship. A greater frequency of auto collisions would occur
in this situation
regardless
of the roadside
vegetation management practices.Consider placing signs to warn motorists at known or expected
wildlife-vehicle collision locations.
Public Perceptions of Unmowed Roadsides
An interview of motorists conducted at a rest stop along an
interstate highway in North Dakota in 1971 (Oetting and Cassel)
provided some insight into public perceptions of unmowed roadsides. The
rest area was at the end of a segment of highway featuring both
mowed and unmowed roadsides. Most of the motorists (82 percent)
did not notice any difference between the areas. When interviewers
pointed out the two conditions, 72 percent stated they preferred
the mowed strips, because they were neater. However, when briefed
on the effects the mowed roadsides had on wildlife, many respondents
wanted to change their answer, because of their positive feelings
toward wildlife.
This research suggests that publicity programs and highway
signs can increase support of roadside management programs.
