Philippine Dipterocarp Forests
- This study provides a detailed description of Philippine dipterocarp forests, including details on climatic conditions and composition in the first pages. Page 430 has a table of natural stand regeneration studies of a range of plots (natural and cut over), listing seedling numbers and size class distribution of 5 species in “virgin Negros rainforest” (Table 3); 7-10 species of Bataan are listed on p. 433-437 (Table V-VII), 6 species in Laguna are listed on p. 438-441 (Table VIII-IX), and multiple species of Mt Maquiling are listed on p. 444-450 (Table X-XII).
- Succession pathways on cleared land are described starting on p. 451.
- Methods and data on growth of a range of forest species are given starting on p. 466. Table XVI-XXXVIII on p. 471-512 includes growth by diameter class in the different forest tracts. Seasonal and annual diameter growth are given starting on p. 517.
- The effect of cutting on dipterocarp forests is described starting on p. 533, including a review of selective logging and diameter limits, which the authors consider unsustainable.
- Planting is described starting on p. 541. The authors do not think large-scale planting of dipterocarps is feasible or economic in the Philippines, neither in grasslands nor in secondary forests.
- General considerations of management are given starting on p. 544.
