RESEARCH INSTITUTE OF WOOD INDUSTRY (CRIWI) CHINESE ACADEMY OF FORESTRY (CAF) 1.The rubber tree planting and rubberwood resources ● Generally rubber tree is just suitable to be planted between 10 degrees southern latitude and 15 degrees northern latitude in the tropical region. ● The total rubber planting area is more than 9 million ha in the world, and more than 90% of which is in Asia, ● Mainly including Thailand, Indonesia,Malaysia, India, Vietnam, China, Sri Lanka, Philippines, Burma and Cambodia.

RESEARCH INSTITUTE OF WOOD INDUSTRY (CRIWI) CHINESE ACADEMY OF FORESTRY (CAF) 1.The rubber tree planting and rubberwood resources 1.1 The geographical distribution of rubber plants in China ● China has a successful precedent to plant rubber trees in the area of northern latitude degrees. ● The rubber plantations : Hainan, Yunnan, Guangdong, Guangxi and Fujian etc total rubber plantation area is about 776,000 ha.

RESEARCH INSTITUTE OF WOOD INDUSTRY (CRIWI) CHINESE ACADEMY OF FORESTRY (CAF) 1.The rubber tree planting and rubberwood resources ● The total natural rubber yield in 2006 is 537,000 dry ton. ● Hainan province: about 402,000 ha Yunnan Province : 334,000 ha ● The crude rubber yield : Hainan % Yunnan %

RESEARCH INSTITUTE OF WOOD INDUSTRY (CRIWI) CHINESE ACADEMY OF FORESTRY (CAF) 1.The rubber tree planting and rubberwood resources 1.2 The area of rubber plants ● The annual consumption of crude rubber in China is more than 2,000,000 ton, ● More than 70% of the total demand relies on import. ● The increasing potential in crude rubber production in China will be very limited only 1 million ha, which is less than 5% of the national territory area, is suitable for rubber tree planting.

RESEARCH INSTITUTE OF WOOD INDUSTRY (CRIWI) CHINESE ACADEMY OF FORESTRY (CAF) 1.The rubber tree planting and rubberwood resources 1.3 Rubberwood logging ● The rubber trees to be cut for renewal State-owned trees :25-30 years Private rubber trees: years The average proportion of renewed rubber trees is 1.5-2% each year. ● The renewed log production for the diameter more than 5 cm Hainan province: 4-5 m 3.per mu Yunnan province:10-12 m 3.per mu. (note: 1ha.=15 Chinese mu)

RESEARCH INSTITUTE OF WOOD INDUSTRY (CRIWI) CHINESE ACADEMY OF FORESTRY (CAF) 1.The rubber tree planting and rubberwood resources ● The total annual rubberwood yield in China : 800,000 m 3 -1,900,000 m 3 (Based on a 20 years of renewal period) ● Annual rubberwood yield: 800,000 m 3 in recent years Hainan rubberwood Yunnan rubberwood

The influence and status of wood supply 1)The renewal quantity of the old rubber trees, 2)The renewal quantity of existing rubber trees for new rubber species and new introduced forest management technique, 3)The cutting amount of rubber trees due to typhoon, insects attack and freeze harm, 4)The influence of heavy rain in harvest season on the cutting and transportation of rubberwood trees The marketing related factors that influence the rubberwood supply include the change of crude rubber price and the change of wood market condition.

RESEARCH INSTITUTE OF WOOD INDUSTRY (CRIWI) CHINESE ACADEMY OF FORESTRY (CAF) 2. The influence and status of wood supply 2.1 The influence and situation of natural rubber price Some aged rubber trees which should be renewed are still serving for rubber harvesting because of their quicker and higher profit, as a result, the rubberwood logging is postponed. These cause the decreasing of rubberwood yield in the long term.

RESEARCH INSTITUTE OF WOOD INDUSTRY (CRIWI) CHINESE ACADEMY OF FORESTRY (CAF) 2. The influence and status of wood supply 2.2 The influence and status of the timber market 1. Wood demand It is estimated that in 2015, the total wood demand will be 460 million m 3 and the gap will be 170 million m 3. That will be helpful to make full use of rubberwood. 2. The trend of wood importation To use more located plantation wood resource and wood based materials will be a good complementary way. 3. The fluctuation of wood price The rubberwood price increased by about 100 yuan/m 3 compared with that in last year.

RESEARCH INSTITUTE OF WOOD INDUSTRY (CRIWI) CHINESE ACADEMY OF FORESTRY (CAF) 3. The status of rubberwood utilization ● The utilization of rubberwood began in 1950's. ● Different specification and grade of the preservative sawntimber can be acoordingly used for furniture, finger-joint glue lumber, blockboard, wood modeling, decorated veneer and handicraft product etc. ● The small size logs or branches are used for particleboard and MDF. ● The annual rubberwood production value reaches to 2 billion yuan.

RESEARCH INSTITUTE OF WOOD INDUSTRY (CRIWI) CHINESE ACADEMY OF FORESTRY (CAF) 3. The status of rubberwood utilization 3.1 The processing and usage of rubberwood sawntimber ● The size of the log: dia. ＞ 5cm ， used as timber or wood based panel materials. ● The method of processing: live saw with only a specific thickness, sawntimber length depends only on the size of the log. ● The size of Sawntimber: thickeness 3.5/4.5/5.5/6.5/7.5cm length 1-2.2m, the width is not specified.

RESEARCH INSTITUTE OF WOOD INDUSTRY (CRIWI) CHINESE ACADEMY OF FORESTRY (CAF) 3. The status of rubberwood utilization ● The price of the sawntimber could be as high as 1.8 times which depends on its thickness. ● Short timber are usually finger jointed or to be made into blockboard and furniture small parts.

RESEARCH INSTITUTE OF WOOD INDUSTRY (CRIWI) CHINESE ACADEMY OF FORESTRY (CAF) 3. The status of rubberwood utilization ● The rubberwood processing is a kind of high labor intensive processing------suitable for its small diameter and bend shap of rubberwood. ● The recovery rate of sawntimber is about 60%.

RESEARCH INSTITUTE OF WOOD INDUSTRY (CRIWI) CHINESE ACADEMY OF FORESTRY (CAF) 3. The status of rubberwood utilization 3.2 The distribution of rubberwood sawntimber ● The distribution way: wholesell or retail in trade market, directly from factory ● The trade of rubberwood sawntibmer is measured by the weight of wood. ● The non-dimmension rubberwood sawntimber is packed and classified by the thickness rather than its length and size.

RESEARCH INSTITUTE OF WOOD INDUSTRY (CRIWI) CHINESE ACADEMY OF FORESTRY (CAF) 3. The status of rubberwood utilization ● The price of Yunnan sawtimber is yuan/m3 higher than that from Hainan province’s. ● The imported rubberwood in China market are mainly dimension timber, which is 37% higher in price than domestic rubberwood timber.

RESEARCH INSTITUTE OF WOOD INDUSTRY (CRIWI) CHINESE ACADEMY OF FORESTRY (CAF) 4. Strategies for the promotion of rubberwood industry development ● Rational allocation of resources to ensure sustainable supply of rubberwood----. Besides the yield of latex, the yield and quality of rubberwood should also be considered ● The management and processing techniques. should be strengthened, and the different processing scales should be supported. ● Promoting the production of dimension timber

RESEARCH INSTITUTE OF WOOD INDUSTRY (CRIWI) CHINESE ACADEMY OF FORESTRY (CAF) 4. Strategies for the promotion of rubberwood industry development ● The improvement in rubberwood preservative treatment techniques and sawntimber quality. ● Established rubberwood products brand as a kind of wood with uniform and elegant color. ● The rules or standard of rubberwood products should be made.
