Seedlings of Secondary Forest Tree Species of East Kalimantan, Indonesia = Semai-semai pohon hutan sekunder di Kalimantan Timur, Indonesia

Non-timber forest products (NTFPs) and some forest tree species are an important source of livelihood to communities. Unfortunately, their potential and uses are much unknown by the population or organization responsible for conservation. It is for this reason that this study was carried out in the village of Minko’o to assess this potential, and to show their importance. A socio-economic survey was carried out in the village and GPS coordinates of the identified NTFPs and forest trees was recorded from the farms/plantations and forest visited. A total of 20 households were surveyed in order to identify the different NTFPs and their utility for the population. Our findings revealed that 50% of the harvest of NTFPs and forest species is done by picking and 45% by collection. Some NTFPs and forest products were known and used by the people. Some of these resources were not known and therefore under exploited. It is the case of Cola (Cola nitida), Soursop (Persea muricata), Akom (Terminalia superba), Mfo (Enantia Chlorantha), Kassimang (Spondias purpurea). Most of NTFPs were grown by the populations and the preferred NTFP was the avocado tree. The forest tree species are mainly used for medicinal purposes. Other trees were used for construction.

Pioneer Plants

Although two studies (Loubry 1994, Sabatier 1985) have been conducted on the phenology of primary forest tree species in French Guiana, there exists little synthetic information on the phenology of a forest dominated by pioneer species. Charles-Dominique (1986) conducted zoological observations at ARBOCEL between 1981 and 1985, where he indicated the fruiting periods of certain species. However, stands of early pioneer plants such as Solanum spp. and Cecropia obtusa Trécul 9Cecropiaceae) have reduced in number or have completely disappeared from the study area since then (Larpin 1989, Toriola et al. 1998).

Syzygium Guineense

AbstractThis study examined the mechanisms of facilitation and importance of seed dispersal during establishment of forest tree species in an Afrotropical woodland. Seedling survival of Syzygium guineense ssp. afromontanum was monitored for 2.5 years at four different microsites in savannah woodland in Malawi (southeastern Africa) under Ficus natalensis (a potential nurse plant), Brachystegia floribunda (a woodland tree), Uapaca kirkiana (a woodland tree), and at a treeless site. The number of naturally established forest tree seedlings in the woodland was also counted. Additionally, S. guineense ssp. afromontanum seed deposition was monitored at the four microsites. Insect damage (9% of the total cause of mortality) and trampling by ungulates (1%) had limited impact on seedling survival in this area. Fire (43%) was found to be the most important cause of seedling mortality and fire induced mortality was especially high under U. kirkiana (74%) and at treeless site (51%). The rate was comparatively low under F. natalensis (4%) and B. floribunda (23%), where fire is thought to be inhibited due to the lack of light-demanding C4 grasses. Consequently, seedling survival under F. natalensis and B. floribunda was higher compared with the other two microsites. The seedling survival rate was similar under F. natalensis (57%) and B. floribunda (59%). However, only a few S. guineense ssp. afromontanum seedlings naturally established under B. floribunda (25/285) whereas many seedlings established under F. natalensis (146/285). These findings indicate that the facilitative mechanism of fire suppression is not the only factor affecting establishment. The seed deposition investigation revealed that most of the seeds (85%) were deposited under F. natalensis. As such, these findings suggest that in addition to fire suppression, dispersal limitations also play a role in forest-savannah dynamics in this region, especially at the community level.
