Study Notes
Forest Formations in the Philippines
- The presentation covers different forest formations found in the Philippines
- A variety of tropical forest types exist; including those over ultramafic rocks, limestone, peat swamps, and more
- These formations vary based on factors like elevation, climate, soil type, and water availability.
Nature of Tropical Forests
- Tropical forests exhibit high biodiversity, holding a large number of species per hectare (up to 10,000)
- These forests are high in biomass, net primary productivity (NPP), and nitrogen (N) uptake.
- Tropical forest soil layers are thin.
- Nutrient cycles in tropical forests are short.
- The structure of the forest is multi-layered, going from emergent trees, to upper canopy, understory, and forest floor.
- Unique plant growth forms, like epiphytes, lianas, climbers, and stranglers, are common.
- The microclimate is generally humid and warm.
Factors Affecting Forest Distributions
- Shifting winds and typhoons are influential in shaping the distribution of rainfall across the archipelago.
- The Kuro-siwo current affects the rainfall patterns, particularly along the eastern coast.
- The varied topography (numerous mountains) contributes to the diverse mix of ecosystems.
- Geographic locations influence the forest formations, such as the Northern Sierra Madre containing large tracts of rainforests.
Specific Forest Types
- Beach Forest:
- Narrow woodland along sandy/gravelly beaches
- Plants adapted to disperse seeds via water
- Some prominent species include Cocos nucifera (coconut), Terminalia catappa (almond), and others.
- Mangrove Forest:
- Occurs along clayish seashores and tidal zones; merging into beach areas
- Soils are usually a mix of sand and coral limestone
- Dominant species include Rhizophora spp., Bruguiera spp., and Avicennia spp.
- Brackish-water Forest:
- Occurs along the inland edge of mangrove forests and tidal limits of estuaries
- Dominated by the Nypa fruticans palm
- The area where soil is wet and/or regularly inundated.
- Freshwater Swamp Forest:
- Regularly or occasionally inundated with mineral-rich water from rivers
- Metzoxylon sagu is dominant within this formation.
- Peat Swamp Forest:
- Found in areas with a water table higher than the surrounding areas, possessing peat (50 cm deep)
- Soil is typically acidic, and incoming water is from rainfall
- Only known in Leyte and Agusan marsh areas
- Tropical Lowland Evergreen Rainforest:
- Ranges from coastal plains to 1200m elevations
- Best found where rainfall is relatively uniform throughout the year
- Characterized by richness in arborescent flora and dominated by dipterocarps.
- Tropical Semi-evergreen Rainforest:
- Experiences yearly water stress, making it distinct
- Contains decidous subtypes, such as yakal-lauan and lauan-apitong
- Found on the western side of the islands, including dry regions like Palawan
- Tropical Moist-deciduous Rainforest:
- Found where water availability is limited
- Found on the western Luzon areas, Palawan, and Mindoro
- Deciduous dipterocarp subtypes are common to this forest type
- Tropical Upper Montane Rainforest(Mossy Forest):
- Located in mountains above 1,000 m elevations
- Characterized by varied topography, steep ridges and moisture
- Dwarf trees and increased prevalence of mosses, liverworts, and ferns.
- Subalpine Rainforest:
- Found on mountain summits with shallow, acidic, and nutrient-poor soil.
- Predominantly comprised of small woody dicots, distinguished from vegetation of other high elevation mountains.
Forest over Ultramafic Rocks
- Growing on soil rich in heavy metals
- Vegetation is sclerophyllous and relatively stunted, ranging from 2-5 meters tall.
- Found in Northern Zambales, Northeastern parts of Mindanao, Dinagat Island, and Northern Leyte.
- Notable plant species include Scaevola, Leptospermum, Brackeridgea, Exocarpus, Gymnostoma, Poutheria, and certain ironwood species.
Forest over Limestone
- Found in low limestone hills, potentially along coastlines or bordering valleys
- Soil is thin, primarily crystalline limestone
- Characterized by a mixture of large trees, smaller trees, and various types of bamboos
- Prominent species include Vitex parviflora and other leguminous trees, often with short-boled and irregularly shaped trees.
Additional Information
- The presentation includes various images and some notes about particular tree species found within specific Philippine forest formations.
- A summary of the classification of specific trees within each formation, and details about their taxonomy.
- References to particular websites and publications are provided throughout the document.
