Abstract

Forestry Sciences Policy and Administration
One of the major constraints in scaling up the production of high quality seedlings of native timber trees in private and government nurseries is the scarcity of information about the distribution and phenology of superior mother trees. There is also a lack of knowledge among seedling producers and seed collectors about the ideal characteristics of superior mother trees resulting in the collection of germplasm from low quality sources. A survey to identify the location and phenology and also assess the phenotypic quality of mother trees of native timber species on Leyte Island was carried out as part of the implementation of the ACIAR Q-seedling Project. The locations of mother trees were recorded using the Global Positioning System and phenologies were determined through local knowledge of seedling producers. The phenotypic quality was assessed using the method developed by the Department of Environment and Natural Resources. A total of 502 mother trees belonging to 32 species were identified. However, almost half of the identified mother trees assessed were of low physical quality - with bent, forking and eccentric stems. There is a need for an information campaign on the importance of germplasm quality and capacity building to encourage seedling producers to adopt the germplasm collection protocol to increase the collection and use of high quality germplasm. The implementation of a forest nursery accreditation policy will provide financial benefits to tree owners and communities, and thus promote the protection of the identified superior mother trees.
