Habitat loss is the major phenomenon threatening species in boreal forests. One example of a threatened affected by habitat Siberian flying squirrel (Pteromys volans). We used mark-recapture data from 1992 to 2004 for 3 populations estimate demographic parameters these populations. Average adult survival was 0.43–0.53, and probability surviving staying near natal territory through first winter 0.23–0.30 different These values are low compared estimates presented literature other Sciurid species. The estimated population growth rates indicated decline all areas. In one areas, we found rate during study. This demonstrated be linked ongoing due logging. Low emigration probabilities suggest that likely sinks. highlights need ensure dispersal between remaining patches suitable successful conservation this associated with old-growth situation worrisome as studied situated an area where densities have traditionally been high.
