Information about game population states and hunting regulation are important prerequisites in ensuring the sustainability of populations. Voluntary game monitoring has a potential of being an important factor in addition to the monitoring made by professionals. The main method in the monitoring of many game species in Finland is the wildlife triangle scheme (WTS), providing abundance estimates of about 30 species. The WTS is largely carried out by voluntarily participating hunting teams. Regardless of the long traditions in the hunters' monitoring activity and hunting regulation, very little is known about the characteristics of the hunting teams that have been active in the WTS. To gain more insight into the characteristics of the hunting teams at a national and regional scale, we analysed quantitative questionnaire data on various activities of hunting teams collected by the Hunters' Central Organization. A typical team carrying out censuses has a large number of members and large hunting grounds, and its monitoring activity is also associated with the voluntary regulation of the hunting of grouse as well as other management actions. The findings indicate that especially large hunting teams are active in voluntary game monitoring in Finland, but also small groups of motivated individuals can successfully participate in the WTS.
