MEDIUM FORESTS A subtype of this forest area with smaller trees of the same variety is found in places of slightly less altitude a foot or 2 lower and generally to the westward of the taller forest or in the south and north of the island and on Mouli island. These are generally on very rock areas and have a dense ground cover of ferns. All the lower types of scrub are proportionately stunted. The higher trees reaching 20-30 ft., lesser ones 15 and smaller only 4 to 5 ft. All are densely tangled with ropes and almost impenetrable without knives. This area forms a greater part of the island forest and is a large factor in the bird life such species as prefer this type of habitat being predominant (Pachycephala Myiagra, Gerygone, Myzomela etc.) Much of the vegetation produces seeds and berries and the ground with a heavy leaf fall and rotten food forming a suitable breeding place for insects and beetles. Stunted small leaved and fruiting banyans also are plentiful in the area. This area has been subject to much disease by cultivation for gardens and permanant coconut culture. Being closer to the areas of habitation and easier cleared than forest and promising a fair degree of fertility in pockets and small areas natives have used it much for cultural purposes. Here and there in the area in fairly extensive patches a thin layer of 3 or 4 inch soil has formed over an almost level unpotholed rock area of 3 and 4 acres and on this a low stunted hardwood scrub tree (Mori, the same as Erromanga N.H.) growing rarely above 10 ft. in height and very scattered, manages to exist,
