The new method of the flying squirrel census by means of excrement presence registration on test plots is offered. Its detailed description and the first results of application in various regions of Fennoscandia are resulted. In Finland in 2003–2006 it has been surveyed more than 10 000 test plots from which 10.3 % have appeared are occupied by flying squirrels (about 11 pairs per 1000 ha). In Karelian isthmus from 707 surveyed plots populated there were 9.3 % (10 pairs per 1000 ha). In the territory of Karelia in 2004–2008 from 927 put and surveyed plots, animals have been found out in 15.7 % (17.5 pairs per 1000 ha). In all investigated areas considerable spatial variability of number of flying squirrels is noted.
