Lowland Dipterocarp Forest

In lowland dipterocarp forest in Sabah, Malaysia, most primary forest bird species were present in areas selectively logged eight years previously. However, certain taxa, notably flycatchers, woodpeckers, trogons and wren-babblers, became comparatively rare. In contrast, nectarivorous and opportunistic frugivorous species were significantly more abundant. Few species appeared to change foraging height, but netting rates suggest that the activity of some species had increased, or that some birds ranged over larger areas after logging. Although there is still much to be learned about the survival of birds in logged forest, large areas of this habitat are important for bird conservation. However, the susceptibility of logged forest to fire, and our present incomplete understanding of bird behaviour and population dynamics in logged forests mean that they should not be considered by conservationists as alternatives to reserves of primary forest.

Detailed Work

The Meathop Wood Project involved the study of a deciduous broad-leafed forest in Lancashire and an attempt has been made to obtain an energy balance for the community and to elucidate carbon and mineral cycling. Measurements have been made of radiation, rate of photosynthesis by the major components of the forest and their productivity. The rate of litter fall, sub-divided into the various components such as eaves, bracts, branches, etc., root productivity and the death of the roots and the addition of organic matter to the soil from this source were measured. The decomposition of the soil litter was followed, and the soil populations of the animals, fungi and bacteria were examined. The mineral uptake by various plant species was followed by monitoring the incoming rain, the through-fall in its passage through the leaf canopy, the trunk-flow and run-off and the leaching of the litter and soil. The processes involved have been summarized in a general energy flow diagram for the forest. Because of the detailed work undertaken by members of the Nature Conservancy staff, much of which was begun before the I.B.P. started, it was possible with the aid of additional workers from universities and the Liverpool Technical College to fill many of the gaps in the original work. Similar but less complete studies were made jointly with the I.B.P. Committees of Japan and Malaysia on a virgin tropical lowland dipterocarp forest situated in Negri Sembilan in central Malaya.

Dispersal Events

The natural seed shadow created by gibbons (Hylobates mulleri×agilis) in Central Kalimantan, Indonesia, was monitored over 11 mo to discern the role of gibbons and post-dispersal events in the spatial pattern of seed germination. Variability in the content and distribution of 183 scats was used to determine which, if any, scat characteristics influenced seed fate. Nine scat characters were evaluated: (1) seed number; (2) number of seed species per scat; (3) scat weight; (4) seed load; (5) rainfall; (6) scat density; (7) distance to nearest fruiting tree; (8) ripe fig abundance; (9) non-fig fruit abundance. More than 99% of monitored seeds were killed, removed, or had germinated during the monitoring period. Vertebrates killed or removed most seeds (86%) and the probability of them moving seeds was highly dependent on non-fig fruit abundance at the time of deposition; factors (2), (6) and (7) also influenced seed removal/predation by vertebrates, depending on whether seeds were deposited in peak or non-peak times of consumption. Insect predation (2% of seeds) occurred mainly in scats that were deposited in months of high ripe fig abundance, while the actual chance of a seed germinating (11% of seeds) was influenced by non-fig fruit abundance at time of deposition and number of species in the original scat. The gibbon-generated seed shadow was profoundly altered by post-dispersal events and variation in the characteristics of the shadow had little lasting impact on the probability of seeds germinating.
