At the same time, we studied population dynamics of seed-eating rodents in the autumn and the following spring. The results showed that, without enclosure protection, most of the seeds were predated due to high predation pressure in the autumn. The emergence rate of seedlings of all the studied species significantly increased under autumn protection, complete protection, and 1-4 cm burial under soil covered by litter. Effects may reflect the seasonal dynamics of rodent abundance and the characteristics of the seeds. We conclude that taking effective measures such as enclosure protection and seed burial according to seasonal dynamics of rodent population would promote survival after direct seeding. %K direct seeding %K enclosure protection %K seed burial %K rodent abundance %K forest regeneration and restoration
