Wildlife detected

Following a (slight) theme of hi-tech solutions comes a report from the LA times last week about a system in Denver Colorado that detects deer and elk crossing the road and warns motorists. The system, which covers a mile of highway on US160, detects changes in the earth's electromagnetic field caused by the presence of large animals. When large animals are detected the system flashes warnings to motorists. Obviously the impetus behind this is more road safety than wildlife conservation but if the costs fall this might be a useful tool. Currently the system costs about $1 million for a mile of coverage.
