Footprint Identification Technique (FIT) / Feed

Footprints are everywhere, and are perhaps the most overlooked source of data on the planet.  WildTrack's Footprint Identification Technique (FIT) can identify species, individuals, sex and age-class to a high level of accuracy from simple images of footprints taken to a standardized protocol. This technique has the benefit of being non-invasive, cost-effective and draws on the strengths of community-skills such as tracking and observation. Our WildTrackFIT community is composed of users in >20 countries and we have FIT species algorithms developed for a range of species from big cats to Pachyderms, bears, mustelids, and even small mammals.If you see footprints as part of your fieldwork, or in another capacity, we'd love to hear from you!

So interesting, thanks for sharing! It's always really helpful for the community to hear about the trial and error that goes into fieldwork. I also never realized that heat-sensing camera traps don't work on certain animals like otters, really curious to learn more - are there strategies to deal with that problem?? Maybe someone from our camera trap group could chime in on that aspect?

Hi Ellie,

thanks for your interest. So I have two possible explanations why the camera traps I used did not release, even though I found otter droppings directly in front of my camera (and later my happy face that I must have gotten them this time even though it was not the case).

I. The Cameras I used in that specific campaign where quite old and I am not too experienced in using them so maybe I did not set them up correctly. This is something I will try to overcome with newer cameras and more training in my next field campaign whenever COVID allows me to travel again...

II. Otters are very well insulated having more than 70k of hair per cm2. I found some fabulous infrared images in a book from Irene Weinberger that showed how little heat otters actually emit and that otters only differed significantly from the background radiation at there feet and nose. So another explanation of mine is that unless these bodyparts are captured by the camera's sensor the camera won´t release.

I will try new Cameratraps the next time I will have the opportunity to do fieldwork in Portugal and will let you know how it went. Until then I will try to work my way around it using footprints :-).

Hi Santhosh, welcome to the FIT community, we're glad you joined!

Karin has explained very nicely the difference between the footprint identification technique (FIT) that we use and the old 'pugmark' technique. I'd say that every technique, FIT included, has strengths and weaknesses. FIT, for example, will not work in an area where footprints can't be found. The pugmark technique was very reliant on expert assessment and was prone to inaccuracies for that reason, but on the plus side it could be rolled out over a huge area and engaged the traditional ecological knowledge that is part of India's cultural heritage. The camera traps that replaced it have had their fair share of problems (difficulties arranging the traps for optimal sampling, cameras being stolen, cameras are expensive etc). Our belief is that using several different non-invasive techniques for any one survey yields the most reliable results. I hope this helps.

Upper level undergraduates

Dear Zoe,

I wonder whether FIT would be good for species-level (rather than individual level) identification of small mammals. We use track tunnels to get prints of dormice (3 species) on carbon soot (metal surface covered by soot). We do have bibliographical reference of those species (Glis glis, Dryomys nitedula, Muscardinus avellanarius) and other "usual suspects" (e.g. Apodemus sp.). Fom some of them, we also have some tracks from captive animals (although not as many as you describe you need in the videos, but we could arrange for more in the future...once the dormice wake up again in the Spring). Is this something worth exploring? We can manually do the id for our current project, but I am interested in developing know-how for the future as well (and use the current project to achieve this).

Alternatively - and equally interestingly for us - we could work on individual level identification of animals of a small Dryomys nitedula population that we have within our research institute's ground (and hence we can easily do lots of field tests etc.)  - ideally involving an undergraduate student in the process as well (come Spring 2020). Would this be something that we could work on, with some guidance - collaboration for you - with the intent of getting a model out for peopel to use across Europe?

Maybe we could discuss sometime? My email is [email protected]
