林蛙生活习性（Rana chensinensis, living habits） In the life cycle of Rana chensinensis, it can be divided into the following three periods, that is, forest demand, hibernation and reproduction. (I) forest life Lin Wacheng frog, breed in the spring, after a short reproductive dormancy in early May began to enter into the summer mountain forest life, until late September, the temperature dropped to 10 degrees Celsius over the average. The forest frog and the frog and other frogs, summer must inhabit the forest, camp completely terrestrial life / in terrestrial life, never entered the river or pond. Forest type of forest frog, mainly broad-leaved forest. In the northeast of the main habitat in birch, oak, poplar, elm, basswood, maple trees of the forest; in the Changbai Mountain area, coniferous forest is the main forest forest habitat type. China Waxi China Rana not love habitat in coniferous forests, especially deciduous pine forest. This lack of shrub and herb layer, the ground is dry, plus special pine secretions, live in the forest frog is very difficult.

Spring has just entered the forest, the forest frog love perched on the sunny slope, and often in the forest edge, wilderness activities; to the summer season, many forest frog moved to live in shady slope, shady slope forest. The living places change, mainly due to climate change in the summer, the climate is as high as 30 DEG C, in this case, transferred to the sunny slope forest, low temperature, relatively cool, suitable for forest frog life. Therefore, in the summer season, the sunny slope forest frog Rana number decreased significantly. As long as love perched on a hillside, not love in the valley water or high mountain life. But in the slope of the place, or flat, peak or valley are distributed. Activities in the forest frog, there is a certain scope and rules. The scope of its activities is its hibernation and r
