About Mammal Web

Why monitor mammals?

Mammals can be very elusive. Often coming out at night, and not in great numbers, it is hard to monitor their populations, where they are distributed, and how they behave. However, knowing these things is very important not only for conservation, but also for knowing how to develop our natural landscape sustainably.


What is camera trapping?

One way to keep track of wild mammals is the use of motion-sensing "camera traps" (they don't actually catch the animals!), which detect and photograph any animal moving in front of them. Camera traps are great because they are relatively easy to set up, and cause less stress to animals compared to the traditional method of capturing and tagging them. If done well, we will not only learn about what and how many animals there are, but also the timing of important events such as when they reproduce. These battery powered camera traps can be left in the wild taking pictures for months, so you don't need to constantly check on them. However, when we deploy many camera traps across a large area, regularly downloading images from them and identifying the animals captured in thousands of photos can become a big operation!


Where citizen scientists (you!) come in 

Since there are thousands of photos, we need the help of volunteers like you to identify the animals in them. This is a type of "crowdsourcing" that has been demonstrated to work on websites like Zooniverse. What makes Mammal Web different, however, is that we would like to take this a step further, and let you set up your own camera traps, and upload the pictures you get with them! The Spotter page lets you identify animals in photos, and the Trapper page allows you to sign up your own camera traps and start uploading.


The team

MammalWeb was created in a collaboration between the Durham Wildlife Trust and a team of scientists at Durham University. We hope to improve the state of mammal monitoring in the UK, and to engage the public in this endeavour.



Durham Wildlife Trust


Durham Wildlife Trust (DWT) is a major organisation helping to manage and conserve Durham’s natural heritage. DWT will use the results of this programme to help to inform proposals for biodiversity planning in the County, as well as responses to planned development.

Pen is a PhD student in the Department of Biosciences at Durham University.


Dr Philip Stephens


Phil is an ecologist in the Department of Biosciences at Durham University. He will be working with Pen to oversee the project and ensure that it delivers information that is useful for local conservation and decision-making.

Dr Steven Bradley


Steven is a computer scientist at the Department of Computer Science at Durham University. He has been helping on all aspects of the project but, particularly, to develop our website, making it user-friendly, functional and fun!

Prof. Russell Hill

Russell is an ecologist in the Department of Evolutionary Anthropology at Durham University. He has lots of experience with camera trapping in exotic parts of the world and is bringing that expertise to bear on this project, so that we get as much as possible out of the initiative.

Prof. Mark Wittingham

Mark is an applied ecologist in the School of Biology at Newcastle University. Mark has lots of expertise in research focused on managing Britain’s wildlife and is also helping to make this project as useful as it can be.



We need your help to look at amazing pictures of wild animals caught on camera, and to take your own camera trap photos!
