The initial plantings were on the site of logged rainforest, the remaining trees of which were poisoned with arsenic. Pine has been planted in this way at various times along the valleys of the Navai, Nadala and Nukunuku and along the top of the escarpment south of Fig. 1. Map showing the study areas 1-6. The shading on the small map of Viti Levu indicates the area covered by the large map. In addition pine has been planted on dry-grasslands where the Nukunuku joins the Sigatoka river and on the steep slopes of the escarpment leading down from Nadarivatu to the coastal plains. I chose 4 major categories of pine: young plantations under 2 m in height in rainforest and on grassland; and mature pine more than 7 m on the same 2 vegetation types. On poisoned rainforest the young pine had a rich under- storey of herbs, bushes and seedlings; the mature forest had a closed canopy and the understorey was much shorter and less diverse. On the dry land, both immature and mature pine had an understorey of grasses and shrubs. The natural vegetation surrounding these plantations is described fully in Gorman (1975). Methods The locations of the 6 study areas, covering the 4 categories of pine planta- tion and areas of natural grassland and rainforest are shown in Fig. 1. Each area was visited for a total of 31 days between November 1970 and May 1973. On each visit I walked irregularly through the area, from 6 to.
