Previous studies show that the successful regeneration of Korean pine forests present a “gap" pattern. Excluding the influence of environmental factors, such as light and temperature, will the scatter-hoarding behavior of squirrels (Sciurus vulgaris) play a key role in such a spatial pattern? In this study, by counting the Korean pine cones that squirrels held in their mouths for hoarding then discarded when they had finished the hoarding behavior, and measuring microhabitat Characters index in original Korean pine forest in the Liangshui national Nature Reserve of the Lesser Xing’an Mountains of Northeast China, we investigated the habitat selection and microhabitat utilization for hoarding behavior of squirrels. Results showed that hoarding behavior of squirrels exist selectivity. The squirrels selected habitat order by major vegetation types is as follows: first original Korean pine forest; second natural fir forest; third manmade fir forest; fourth mix-conifer leaf forest; fifth manmade fallen leaves pine forest; sixth mix-conifer-broadleaf forest; seventh mix-broadleaf forest; eighth birch forest; finally manmade Korean pine forest. Compared with the result, using cache spots as an index, the order of habitat selection changed, revealing that the latter research should include more factors, such as pilfering by other animals and second dispersal by the squirrels themselves or other species, and so forth.The Vanderploeg and Scavia selectivity index, Wi and Ei, were used to evaluate the microhabitat utilization of squirrels in the original Korean pine forest. Results indicated that the squirrels had a significantly micro-habitat utilization pattern: (1) Squirrels prefer to use the micro-habitat in original Korean pine forest with the high canopy, medium shrubby density, medium stub density, where pilfering animals are few (Ei＞0.2); (2) Squirrels did not like to utilize the micro-habitat in original Korean pine forest with a low slope degree, high density of fallen logs and stumps, high herbage cover and an abundance of pilfering animals(Ei＜-0.2), and they show dislike for a shaded slope (Ei=-0.5368). This kind of selectivity of microhabitat utilization for hoarding behavior of squirrels play an important role in the Korean pine seedling spatial pattern.
