    Wild Track is an organization that aims to protect endangered animals like rhinos. They use a computer program that runs photos of animal track through an algorithm (演算法).Then the program makes the same observations as a tracker would, allowing scientists to know where individual animals go. However, the program itself needs “training”.

It starts with collecting good photos of prints from endangered animals in captivity  ( 圈养）.As people send in photos of tracks from animals in the wild, the FIT program can compare it to tracks from animals it “knows”. As the program becomes more accurate, Wild Track hopes it will become a major tool for monitoring any endangered species.

Anyone can help Wild Track by taking images of tracks and sending them to a partner organization called naturalist.org. The only tool you need is a digital camera or cellphone. After finding a clear track, place one ruler along the bottom of the footprint and another along the left side. Below the footprint, place a note containing your exact name and the date. Holding the camera or cellphone directly above the track, take a photo showing the footprint, rulers and note. Later, visit naturalist.org and follow the instructions on the site to send your photo.

Wild Track needs photos of footprints made not only by animals in captivity but also those living in the wild. In wild places, you should take care not to disturb animals in their natural environment. If you intend to photograph in a wild area that is unknown to you, then you should not go there alone. Instead, go with someone who is familiar with the region and experienced at tracking.
