This project explored the possibility of harvesting marketable foliage stems in addition to producing timber from plantations of Larix leptolepis, Cupressus macrocarpa ‘Goldcrest’ and Tsuga heterophylla. Data recorded from trial sites included both growth parameters, in the form of height and diameter increments, and production parameters in the form of foliage stem yields. Results varied with species and site type. In many cases, results achieved appear to have been influenced more by the biology of the trees than by the treatments alone. Trials were also established to investigate methods of managing old or over grown Abies procera Christmas tree plantations for forest foliage production. Shelf life testing and market research into the domestic trade of forest foliage were also conducted over the course of the project. Recommendations for managing forest plantations for foliage production as well as a general discussion on the industry are presented in this report.

The sterile castes of Ibitermes inflatus sp. nov. from Rio Tinto, State of Paraíba, Brazil are described and illustrated. This is the first record of a species of Ibitermes from the Brazilian northeast and from the Atlantic Forest biome. The absence of ridges in the molar plate of the left mandible and the presence of granules of sand and silt mixed with organic matter in advanced stage of decomposition in the digestive tube of workers suggest that the species is a typical humus feeding termite.
