Philippines

background

This study concerns the survival of 12 native pioneer species and one exotic species when directly sown into grasslands (Themeda triandra and Imperata cylindrica grasses). They were monitored for 16 weeks . The Authors note that direct seeding studies are important because direct seeding is cheaper and faster than nursery propagation.

background

This book chapter provides a description of the ecological effects of deforestation in the Philippines and a history of the failed social forestry programs that began in the 1970s.

• 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.

• This Bureau of Forestry authored document describes reforestation efforts to recover areas degraded by shifting agriculture. A forest nursery was established in 1910 to determine best forest tree species for “artificial reforestation of cogon lands” and in areas of “second growth of no commercial importance”- 600 species were experimented with.
