Seed sourcing andgenetic aspects in restoration in Thailand Suwan Tangmitcharoen Forest Research and Development Bureau, Royal Forest Department suwantang@hotmail.com, Presentation for Capacity-building workshop for selected sub-regions of Asia on the restoration of forest and other ecosystems , Bangkok, THAILAND June 30, 2016 www.forest.go.th
OUTLINE OF THE PRESENTATION Introduction Genetic diversity of some important native species Seed source and Classification Lesson learned from experiences Approaches under Climate Changes: Options for future management
Forest cover in Thailand 32.62% of the country area 102,285,400 sq.km. North 23.97% 52.60% North-east 22.18% Central East 15.02% 32.86% South Year 2014
Major Forest Conservation Areas in Thailand in 2014 0.05% 0.04% 1.39% 4.10% National Park Wildlife Sanctuary Non-Hunting Area Forest Park 35.18% Botanical Garden 59.25% Arboretum Source: Department of National Park ,Wildlife and Plant Conservation (2014)
The target is to bring the forest cover to 40% of the country area Protected Forest Economic Forest 25% of the country area 15% of the country area FOREST AREA
Forest Biodiversity of Thailand > 2,000 species Number of species of Flora & Fauna 8% of the world flora & fauna endemic only to Flora : 10,000 THAILAND Fern : 658 Orchid: 1,140 Mammals: 302 Birds : 928 Reptiles: 350 Amphibians: 137 Fresh Water Fishes : 720 Marine Fishes : 2,100 Source: Thailand National Report on the Implementation of convention on Biological Diversity ( Report on 2009 )
Top Priority Species on Forest Genetic Resources of Thailand Dalbergia cochinchinensis Afzelia xylocarpa Dipterocarpus alatus Hopea odorata Pterocarpus macrocarpus Tectona grandis Sour: *Chantragoon et al., (2012)
Genetic Conservation First Era: tree introduction, species trail, botanical garden) Second Era: tree breeding (provenance trails, progeny test) Third Era: Linked with breeding & biotechnology – DNA Molecular) (Soekotjo 2001)
Genetic Diversity of SiammeseRosewood ( Dalbergia cochinchinensis) Geographic distribution can be categorized into 2 groups Yooyuen(2012) Soonhuae(1994)
Teak Seed Zone (GenecologicalZones) Graudal et al. 1997 Tectona grandis
Geographical grouping of teak populations in Thailand based on the results of the DNA structure analysis identified 6 regions and 1 admixture zone Saichat Pongkrawee & Hugo Volkeart, In preparation
Sources of Seeds Plantation Natural (Improve genetic materials ) • Difficult access • Easy access • Difficult seed • Easy collection collection • Cheaper • More expensive seed collection

Lesson learned from experience o Seed source from (improved) plantation is better than from natural forest. o Breeding strategies of (each) species should be developed. o Biotechnology help to enhance effectiveness and speed up of improved seed source establishment. o Seed exchange is necessary for effective genetic test.
Approaches under Climate Changes: Options for future management o Develop specific breeding program (well adapted to changing environment) o Ensuring quantity and quality of seed sources o Establish static conservation (Cryopreservation, cold storage freeze preservation of vegetative part) to preserve improved genetic materials
Development of cryopreservation techniques for long-term in vitro conservation of Siamese Rosewood ( Dalbergia cochinchinensis Pierre) Shoots from tissue culture Keep the shoots in Liquid nitrogen (-196 celcius) RFD
