Abstract/Summary:
Seed predation and desiccation present major limitations to the use of direct seeding as an efficient forest restoration technique. The study was designed based on the premise that scarifying seeds before sowing them in fields cleared of weeds would shorten seed dormancy to decrease the time available for seed predation to occur and that burial conceals seeds from potential predators. Therefore, the effects of four treatments (scarification, burial, application of mulch and scarification with burial) were tested on seed germination of four native forest tree species, sown in abandoned agricultural land in an upper watershed in Doi Suthep-Pui National Park, northern Thailand. For certain suitable species, this technique could offer an effective, cost-efficient alternative to outplanting nursery-raised seedlings for forest restoration projects, particularly in montane areas.
