Designing a wildling collection strategy to support production of planting materials for green offsets in Southern Mindanao

摘要

Wildlings or naturally germinated seedlings typically collected from forest areas are widely used in the Philippines for production of planting materials for dipterocarps and other native tree species, due largely to the scarcity of seed of these species, because of their irregular fruiting and short viability period of seed. Where large-scale planting of native species - and particularly use of endemic germplasm – is required, it becomes necessary to develop a carefully planned wildling collection strategy. This paper examines components of such a strategy, from a supply chain perspective. Important steps noted are assessment of the availability and locations of wildlings, organization and training of a wildling collection teams, with scheduled with availability of recovery chamber s in nurseries, and closely coordinated the planned timing of outplanting.
