  1. Estimated number of species of plants (including algae and fungi) currently known from the Philippines (data from Gruezo 1979; DENR-UNEP 1997; Villareal & Fernando 2000; Barcelona 2002) Fernando et al. (2006)

  2. Threatened plants of the Philippines (2005 assessment by the Philippine Plant Conservation Committee) CR – Critically Endangered; EN – Endangered; VU- Vulnerable; OTS – Other Threatened Species; OWS – Other Wildlife Species; PE – Possibly Extinct. Fernando et al. (2006)

  3. Conservation of the Philippine TeakTectona philippinensisBenth. & Hook. f. Amelita C. Luna Aileen S. Peria Marilyn O. Quimado Randy A. Villarin

  5. General Characteristics • Small tree up to 15 m tall, bole with a diameter up to 50 cm. • Leaves elliptical-ovate to ovate-lanceolate, 8-15 cm x 3-6 cm, glabrous or nearly so on the upper surface • Flowers nearly 8 mm long, calyx funnel-shaped, corolla white; • Fruit enclosed by a non-inflated calyx

  6.  Phytogeographical Distribution • Restricted distribution • Grows in highly vulnerable habitat: found in highly disturbed forest edge, surrounded by agricultural land and degraded forest • Confined to two areas in the Philippines: Batangas and Mindoro in Luzon Island ; restricted to limestone forest

  7. Why Philippine Teak? • Endemic • Endangered (IUCN Red List) • One of the only 3 known teak species in the world • Has potential as a genetic resource for future teak breeding programs • No biological and ecological study has been conducted

  8. Threats • Overharvesting/ Unsustainable logging • Land use conversion/ Shifting cultivation • Introduction of exotic species • Preference for immature trees for timber

  9. Economic Importance • Wood is used for heavy construction • Substitute for molave (Vitex parviflora); used for railroad ties

  10. Ecological Importance • Potential reforestation species in dry places like the northwestern part of Luzon.

  11. Studies conducted • Clonal propagation/mass multiplication through micropropagation or macropropagation • Castañeto • La Salle

  12. Act No. 315 and Republic Act No. 826 legislation related to biodiversity conservation and management for the benefit and enjoyment of the Philippine people Presidential Decree No. 705 provides major framework for the management, conservation and utilization of the forest resources in the country Executive Order No. 247, Bioprospecting Lawprescribes the guidelines and establishes a regulatory framework for bioprospecting of biological and genetic resources, their by-products and derivatives for scientific, commercial and other purposes Legislative and Policy Measures DENR Adm. Order No. 96-21 – use of dipterocarp and indigenous tree species in reforestation

  13. What conservation action is needed? • A conservation program is needed to re-establish a stable population in its known habitat. • A rapid assessment of species and long-term ecological research is required to determine the physical and biological characteristics of the habitat. • Couple it with a recovery and management program, public education, community consultation and resource stewardship, and policy initiatives.
