Description
The dataset consists of classified images from small mammal camera traps. The images are processed using the semi-automatic workflow established by Böhner et al. (2023). We use a pre-trained machine learning algorithm to automatically classify all images. Images classified with low confidence or from species/species groups that are challenging are manually annotated. Abundance indices can be estimated following temporal and spatial aggregation of detection events following Kleiven et al. 2023.

Project
| Title | A national monitoring program for small rodents in alpine tundra |
|---|---|
| Description | Small rodents are a key species with strong impact on plants, herbivores and predators in the alpine tundra food-web. In 2023 the Norwegian Institute for Nature Research established a national monitoring program for small rodents based on camera trap in the Alpine Tunda on behalf of the Norwegian Environmental Agency. The program in based on the tunnel camera traps, developed specifically to monitor small rodents on the tundra year round. The trap is described in detail by Soininen et al. (2015). From the initiation of the program monitoring were established in Finse, Snøhetta, Børgefjell, Joatka and Komagdalen. In each mountain area we cover the most important habitat for small rodents (heath, hummock mire and snowbed) and two alpine zones (low and mid alpine zone). See Kleiven et. al. 2022 for further details about the monitoring program. |
