The poulation cycles of small rodents and shrews in Lierne Municipality, Trondelag county in Norway have been followed during the years 2018-2021. Population index based on the same traplines and 3 times a year is investigated for the species: The Bank Vole (Myodes/Chletrionomys glareolus; The Grey-Backed Vole (M. rufocanus), The Field Vole (Microtus agrestis, The Wood Lemming (Myopus schisticolor) and Lemming (Lemmus lemmus). Here is presented the data for 2018-2021. Data also includes catches of the Common Shrew (Sores araneus), Pygmy Shrew (S. minutu) and Water Shrew (Neomys fodiens).

Lierne Municipality, Norway. The trap-lines are placed in North-boreal spruce dominated forest - one line in an oldgrowth, natural blueberry spruce forest - mixed with birch. The other line in a young, planted spruceforest after clearcutting, partly at the egde of minerotrofe herb-dominated bogs. Altitude approx. 540 masl.

座標(緯度経度) 南 西 [64.4, 13.813], 北 東 [64.41, 13.83]


The catches are aimed on small rodents (Rodentia) and shrews (Soricidae). Main species will be: The Bank Vole (Myodes/Chletrionomys glareolus), The Grey-sided Vole, (M. rufocanus), The Field Vole (Microtus agrestis), The Wood Lemming (Myodes schisticolor), The Lemming (Lemmus lemmus), The Common Shrew (Sorex araneus), The Pygmy Shrew (S. minutus) and The Water Shrew (Neomys fodiens).

Order Rodentia (Rodents)
Family Soricidae (Shrews)


生成(収集)期間 2018 - 2021


The Research collect data on small rodents and shrews in this forested area to follow populations dynamics through the years 1988 - 2021. This part is a follow up research for the years 2018 - 2021 for the same area and traplines.

Study Area Description The study area is in a Northern Boreal Spruce (Picea abies) dominated forest about 540 m-a.s.l. One part of the trapline is in Old-Growth Spruce forest, the other half is in young succession, planted spruce forest after a clearcut from approx. 1960. Vegetation types is given in the dataset but mainly blueberry forest in the oldgrowth and more herb-dominated in the young, cultural forest.
研究の意図、目的、背景など(デザイン) Trapline with50 mouse traps sat at approx. 5 m. distance, staying out for 2 nights. See: Sampling methods

Ordinary mouse traps (for killing mouse) have been put out with 5 m. distance through the two traplines, each with 50 traps, bated with raw potatoes. Traps are with few exceptions out for 2 nights and 3 times a year: Mid June, late July/early August and September/October. The same traplines and trap spots have been used all years.

Study Extent The study was conducted from 1988 through 2021 and will continue for another year with collection of more detailed data. The approximate coordinates for the trapsites is: N64.24.20 - E13.49.00 in Lierne municipality, Trondelag county, Norway. Habitat is Northern Boreal Spruce forest. One trapline is placed in natural old-growth blueberry-dominated forest. The second trapline is placed in younger succsession cultural spruce forest, edging a richer vegetation and wet, rich minerogen mire. The traplines are located approx. 540 m.a.s.l..
Quality Control Mouse and shrew species are visually determined on spot, aged as adult, subadult and juveniles, weighed and sexed whenever possible.

Method step description:

  1. The results give a total and species specific, population index calculated as Number/100 Catch-Nights. The results will give an comparable index for population cycles over a 35 years period for this area.
