PINE TAPPING INSOUTH AMERICA

1. Why crude gum production is different in South America.

2. Where crude gum is produced.

3. How crude gum is produced.

4. What we are doing to improve the “tapping technique”.

5. ... and what about the future of “pine tapping” in South America.

NATURAL FOREST vs. PLANTED FOREST

1. Why crude gum production is different in South America.

FARMER vs. PINE TAPPING COMPANY

2. Where crude gum is produced in South America.

TROPIC OFCAPRICORN

Tropical pines:P. car. var. caribaeaP. car. var. hondurensisP. car. var. bahamensisP. oocarpa

Subtropical pines:P. elliottii

3. How crude gum is produced = CUT ONTO CAMBIUM

• CUT (STREAK) MADE EVERY 15 / 21 DAYS REMOVING BARK, PHLOEMA AND CAMBIUM.

3. How crude gum is produced = STIMULATION

• CHEMICAL STIMULANT APPLIED IN PASTE FORM.

• STIMULANTS: CEPA and SA.• DEVELOPING STIMULANTS

WITHOUT H2SO4.

5. What we are doing to improve the “tapping technique”.

• USE LESS TREE SURFACE

5. What we are doing to improve the “tapping technique”.

• PLANTING SELECTED SEEDLING FOR BETTER WOOD AND PINE GUM YIELD

5. What we are doing to improve the “tapping technique”.

• PLANT WITH A WIDER SPACING TO GROW STRONGER TREES AND OBTAIN BETTER SUN ILUMINATION.

6. ... and what about the future of “pine tapping”in South America.

• Based on big forest owners.• Supported by medium size forest owners (100 to 1,000 hectares).• Short forest rotation (< 15 years?).• Better understanding of how the pine tree produces crude gum (oleoresinosis).• Less intervention. • Planting exclusively for crude gum production (?).• Mechanization.
