Project details

Project title: Population research on small rodents (Rodentia) and screws (Soricidae) in Steinkjer Municipality – Norway; 1996 – 2017 based on systematic catches with ordinary mouse traps in traplines
Personnel: Bjørn-Roar Hagen, Pål F. Moa
Funding: The main funding is by Nord university as this is part of a education/Class program. Processing the data is partly funded by The Norwegian Ministry of Climate and Environment.
Study area descriptions/descriptor: Transect 3 is a new cut area of lowland boreal - spruce dominated forest. Due to succession porocesses traps have been put out on different clearcuts in the vicinity to keep trapping at a grass/herb dominated secondary, young succsession stage.
Trancect 4 was in an old, mature spruce forest near to transect 3 and with same vegetation type.
Design description: Given in "Description"

Methods

Method step description: Rodents and screws are protected species in Norway and trapping in nature is only permitted for scientific and/or pedagogical purposes. Permits are given for this research by The Norwegian Ministry of Climate and Environment. 
The Method is in itself simple and decribed earlier.
Study extent description: The collection of data is done once a year in september. Purpose is partly to teach students the methods and ability to identify mouse species, but also as a part of a long term population cycle study for the region.
Sampling description: Given before.
Quality control description: The species and sex is controlled by students and verified by the teachers in cooperation.
