Title of the project

Triangle counting of game species

Description

The triangle counting of game species is a basis of national game population estimating system.

1600 permanent triangles.
Once a summer (in October) and once a winter (in Jan/Feb) the triangle lines (4km each) are searched.
In summer observations of following species are reported : grouse species, capercaillie, black grouse, hazel grouse, willow grouse, hare, woodcock and all observations and findings of bears.
In winter snow tracks of following species are reported: hare, brown hare, red squirrel, Siberian flying squirrel, American/European beaver, muskrat, grey wolf, red fox, arctic fox, raccoon dog, brown bear, stoat, least weasel, American mink, polecat, pine marten, wolverine, badger, otter, lynx, wild boar, white-tail deer, moose, Finnish forest reindeer and roe deer.
All sight observation of the following species will also be reported: capercaillie, black grouse, hazel grouse, Grey partridge, pheasant, northern goshawk and raven.
Data are analysed giving estimates of the densities of different areas’ populations.
Results improve the knowledge of game species populations, their development and trends. They also give information on how hunting affects them, the interaction between predators and prey, between the habitat and prey/game and the diversity of game fauna.
Results are used for setting the hunting quotas and making conservation actions necessary.

Monitoring mainly done by hunters but not coordinated by the Association
