Project Data

Ordinary Norwegian RAPP mousetraps are put out in a line - 5 meters apart at spots selected to be a good place to catch mouse. Traps are baited with pieces of raw potatoe. The normal number of traps have been 100 in each transcept, but deviation from this occur. Traps are our for 2 nights - approximate 40 hours. Catches are picked up every morning.

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
Identifier Ole Jakob Sørensen
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 Description 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.

Sampling Methods

Given before.

Study Extent 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.
Quality Control The species and sex is controlled by students and verified by the teachers in cooperation.

Method step description:

  1. 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.
