Automate invasive species recognition for New Zealand camera trap images

Addax Data Science has been asked by the Department of Conservation (DOC) to develop a species recognition model to differentiate between 17 species or higher level taxons present in New Zealand. It was trained on a set of approximately 2 million camera trap images from various projects across the country.

The model has an overall validation accuracy, precision, and recall of 98%. When tested on an out-of-sample test set, the model scored 95%, 96%, and 94%, respectively. The model was designed to expedite the monitoring of New Zealand’s invasive species (deer, possum, pig, cat, rodent, and mustelid). It is published open-source and can be deployed through our camera trap analysis desktop application, EcoAssist.

Continuous real-time monitoring and deterring system for wolves

After 150 years of extirpation, the wolf has returned to the Netherlands as a protected species. The fragmented Dutch landscape and densely populated countryside, however, poses challenges. The high number of roads increases the risk of collisions, whereas the wolf poses a threat to the abundantly present livestock.

Addax Data Science, in collaboration with Kim Hendrikse, investigates the feasibility of a 24-hour monitoring system to continuously check for the presence of wolves. This real-time detection system, capable of deterring the animals with sounds or light flashes, aims to reduce human-wolf conflicts. By addressing potential encounters and protecting both wolves and livestock, this initiative can contribute to the sustainable coexistence of humans and wolves in the Netherlands.

Study to investigate influence of tree cover on carrion partitioning

Carrion plays an important role in maintaining ecosystem stability and provides feeding opportunities for numerous scavenger species around the world. Vertebrate scavengers are responsible for the large majority of carrion consumption and compete with each other for these resources. The aim of this study was to investigate the partitioning among avian and mammalian scavengers. We examined the influence of ambient tree cover, carcass openness, and repeated use of carcass provision sites on i) the relative and absolute number of scavengers, and ii) time-to-detection, time-to-first-scavenging and time-to-depletion by monitoring the exploitation of large ungulate carcasses with motion-triggered cameras. We found that the proportion of vertebrates scavenging from carrion and their ability to detect it were strongly associated with tree cover. Read the full article here.

Species recognition model for the Namib Desert biome

Desert Lion Conservation is a small non-profit organisation dedicated to the conservation of desert-adapted lions in the Northern Namib. Their main focus is to collect important base-line ecological data on the lion population and to study their behaviour, biology and adaptation to survive in the harsh environment. They use this information to collaborate with other conservation bodies in the quest to find a solution to human-lion conflict, to elevate the tourism value of lions, and to contribute to the conservation of the species.

Addax Data Science has been asked to develop a species recognition model to differentiate between 25 species or higher level taxons. The model can be deployed through our camera trap analysis desktop application, EcoAssist. Learn more about the project here.

Database management system to track cash grant payments

Inclusion foundation contributes to eradicating extreme poverty worldwide by distributing cash grants via mobile money. Through their basic income projects, they want to help people directly and develop an effective, scientifically tested approach. In order to do so, they need a reliable automated method to manage the payment information.  

We have created a software management system that can track transactions, expenses, participants, households, family relationships, statuses, phone numbers, and other community demographics. The system calculates conversion rates, transactions and destinations for all participants and keeps track of administration. The information is exported to the desired format to be sent to the financial department. 

Desktop application for automatic species detection in camera trap analysis

EcoAssist is an application designed to streamline the work of ecologists dealing with camera trap images. It’s an open source AI platform that allows you to analyse images with machine learning models for automatic detection, offering ecologists a way to save time and focus on conservation efforts. EcoAssist is a collaboration between Addax Data Science and Smart Parks to support open-source projects in nature conservation. 

The software has the open-source MegaDetector model incorporated, which can filter out images containing animals, people, and vehicles. It also supports the deployment of custom project specific species recognition models to be used in conjunction with MegaDetector.
