Computers on Track of Rat Pests

Researchers from New Zealand have written software that enables a computer to recognize rat footprints from those of other wildlife, and tell the difference between species of rats.

AUCKLAND, New Zealand - Auckland university researchers have written software that enables a computer to recognize rat footprints from those of other wildlife, and tell the difference between species of rats.

"By identifying rat species we can understand patterns of invasion on predator-free islands, or detect new species entering New Zealand," biologist James Russell said.

The software can be used to read cards left on either side of an inkpad that pests walk over in tunnels placed in vulnerable sites such as predator-free islands or cargo crates.

Footprint cards are a cheap method of identifying animals, particularly ones present in low numbers, or difficult for human observers to find.
