| Research Abstract |
Litter layers in parks and recreational forests are generally abandoned as plant waste, while those include many woody seeds and have some potential of-seasonal seed bank. This study presents early growth of woody seedlings, germinating out of litter layers, for the purpose of reusing them. Litters were gathered from campus parks and its forests, and then were laid out different centimeters thick on the experimental plots. Those litter layer plots were prepared on the forest floor and also in the open field. As results, the germination and seedling growth were affected by water content and temperature within litter layers, due to the difference of layer's thickness. A good growth of seedlings out of litter layers paved on the open field suggested, potential of revegetative technique reusing litter layers, It becomes clear that litter layers are a seasonal seed bank.
