Direct Seeding of Forest Trees in Grassland Communities of Carranglan, Luzon Island

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.

One Century of Forest Rehabilitation in the Philippines: Approaches, Outcomes, and Lessons

background

This chapter provides a review of reforestation efforts in the Philippines, beginning with small-scale forest rehabilitation efforts since 1910. Reforestation was traditionally implemented by government and private companies. Since the mid-1970s, international funders have driven these efforts.

Effect of Vegetation Restoration on Soil and Water Erosion and Nutrient Losses of a Severely Eroded Clayey Plinthudult in Southeastern China

Background

In this study, researchers compare erosion from reforested and degraded sites in subtropical southeastern China.

Goals & Methods

The objective of the study was to estimate the long-term influences of reforestation on soil and water erosion and nutrient losses in regions of southeast China that are characterized by severely eroded bare land derived from Quaternary red clay. The study examined surface runoff, soil erosion, and soil nutrient content.

Reforestation in the Philippines, Proceedings from the Fourth Pacific Science Congress, Java

  • 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.

Annual report of the director of forestry of the Philippine Islands for the period 1907-1913

background

This report contains a number of sections relevant to early reforestation activities in the Philippines, including research on succession pathways, restoration experiments on degraded lands, tree nursery operations, and native species.

conclusion & takeaways

This report provides the rare opportunity to look at the history of forestry and ecological activities in the tropics. These activities and projects can now be analyzed in the full context of the past 100 years, wherein the arcs of their success, failure, and learnings can be more fully understood.

Special Report of Captain George P. Ahern, Ninth U.S. Infantry, in Charge of Forestry Bureau, Philippine Islands, Covering the Period from April, 1900, to July 30,1901

background

This 139-page report outlines the state of the Spanish colonial Forestry Bureau at time of arrival of US forces in the Philippines (~1900), and reforms instituted by Captain Ahern. He describes the timber business in the Philippines including the state of the forested lands, species exploited, and volumes exported. At that time, 160 species of native trees were exported, but the Forestry Bureau knew of 665 native tree species. Ahern suggests trying to find a use for them to make timber extraction more profitable. Samples of 100 species were sent to the US for exhibition.
