Growth data was obtained from 1640 saplings planted between 1999 and 2004 on seven reforestation plots. Survival rates were greater than 90% across most species. Growth rates of planted saplings were
significantly affected by species, site and interaction between species and site. A number of primary forest
species performed well in this study. In comparison, many of the secondary forest species had slow to medium growth rates. Of the 45 species tested, 19 had diameter growth exceeding 1 cm year-1 while seven had growth rates below 0.5 cm year-1. This study showed that many primary forest species can grow well in open conditions of deforested sites. The results also emphasized the importance of site-species matching and the region-specific nature of species performance. The approach of interplanting fast-growing native species with primary forest species was shown to be a viable forest restoration method. Continued monitoring will reveal more information on the long-term performance of these planted saplings and native forest
development in the restored forests.
Prestasi 45 spesies pokok asli yang merangkumi pelbagai jenis pokok daripada spesies sesaran ke spesies hutan primer dinilai dalam satu kajian penghutanan semula di atas tanah ternyahgred di Singapura. Data pertumbuhan diperoleh daripada 1640 anak pokok yang ditanam dari tahun 1999 hingga tahun 2004 di tujuh plot penghutanan semula. Kadar kemandirian melebihi 90% bagi semua spesies. Kadar pertumbuhan anak pokok dipengaruhi oleh jenis spesies, tapak dan saling tindakan antara spesies dan tapak. Sebilangan spesies hutan primer menunjukkan pertumbuhan yang baik dalam kajian ini. Sebaliknya banyak spesies hutan sekunder tumbuh dengan perlahan atau sederhana. Daripada 45 spesies yang dikaji, 19 mempunyai pertumbuhan diameter melebihi 1 cm setahun dan tujuh mempunyai kadar di bawah 0.5 cm setahun. Kajian ini menunjukkan bahawa banyak spesies hutan primer dapat bertumbuh dengan baik di kawasan terbuka di tapak yang terbasmi hutan. Keputusan turut menekankan kepentingan padanan spesies dan tapak serta ciri kawasan tentu bagi prestasi spesies. Pendekatan penanaman selang bagi spesies asli yang cepat tumbuh dengan spesies hutan primer terbukti merupakan kaedah pemulihan yang baik. Pemantauan berterusan akan memberi lebih banyak maklumat tentang prestasi jangka panjang anak pokok ini serta pembangunan hutan asli di hutan yang terpulih. | Item Type: | Journal |
