The AudioMoth is an inexpensive, energy efficient acoustic device that was developed in the UK (collaboration of University of Oxford and University of Southampton) recently. Interestingly, it has the capability – with the approriate detection algorithms – to detect in real-time sounds of interest, in addition to the alternative of recording continuously.
A new article was just published by the AudioMoth research team at Methods in Ecology and Evolution describing the capabilities and potential of this autonomous recording unit (ARU). Do take time to read it – link to the article provided below.

We are happy to inform you that our project’s publication presenting our first results from the passive acoustic monitoring project at Korup National Park was published recently (Issue 5 / June 2017).
“Passive acoustic monitoring as a law enforcement tool for Afrotropical rainforests”
If you don’t have access to the journal online, please use this website’s “Contact” page to email us requesting a digital copy.
Read a post by our project’s member Peter Wrege at the official blog of the “Methods in Ecology and Evolution” journal, featuring some results from our study. Enjoy!
You can interactively visualize and explore the gunshot data from Korup NP by following the link provided in the Data/Results tab of this website.
We have now included in the Data/Results tab of the website a link to the standalone gunshot detection algorithm we used in our project. We look forward to hearing from you about projects that you used the algorithm. We would be glad to share a link to your project on this website. Happy data scanning!
From Nov. 2014 to Nov. 2015 we monitored wildlife and gun hunting activity within the Rumpi Hills Forest Reserve (southwest region of Cameroon). The project was funded by the USFWS (E14AP00503) and coordinated by Joshua Linder (James Madison University), with co-PIs Christos Astaras (University of Oxford), and Peter Wrege (Cornell University). The goal of the project was to demonstrate how the passive acoustic monitoring protocol (PAM) developed in Korup National Park (just a few kilometers away) could be “exported” in new sites, providing insight on wildlife status and human activities within protected areas which are currently totally unmonitored, so as to help develop the momentum needed to make these “paper parks” actually managed/monitored.
You can read our final report to USFWS below. Importantly, we managed to detect the species-characteristic male Preuss’s guenon “boom” call in several sensors, confirming the persistence of the endangered primate within RHFR. We are currently developing an automated detection algorithm for the species that will facilitate rapid acoustic surveys in other forest fragments within the historical range of the species in Cameroon and Nigeria. Our acoustic data also showed that RHFR is under significant gun hunting pressure, and that – especially if the Wildlife Sanctuary status considered for the site is to be pursued as discussed for years now – some level of patrolling and monitoring needs to be introduced at the site.
We will be developing a series of management and monitoring recommendations – as per the project plan – to share with our colleagues in Cameroon and specifically the regional delegation of the Ministry of Forest and Wildlife (MINFOF).
