AN EXCLUSIVE SYMPOSIUM ON RESIN EXTRACTION METHOD AND LANATANA ERADICATION METHOD

4. Introduction
Started in 1606 as a Novel stores Industries in America .
America used resin for sealing the crack hole in the boat.
India started Tapping work in 1896.
Earlier European and Asian Countries where practiced “Lip
& Cup” Method.
Later an improved method commonly known as “Rill
Method” standardized at Forest Research Institute ,
Dehradun to overcome the Lip & Cup Method.
As per Rill Method the yield is 25% more per Tree per
Season compared to other methods.

5. Different methods of Resin tapping
1.French cup & lip method 2.Rill method 3.Bore hole method
Resin is obtained by tapping standing Pinus roxburghi.
There are 3 different methods of tapping-

6. Bark Shaver
Blaze frame
Spray Bottle
Marking Gauge
Hammer cum Nail Puller
Groove Cutter
Collection Can
Pot Scrapper cum groove cleaner
Tools used for Rill Method

Steps for Resin Tapping using
Rill Method

8. Preliminary Procedure – Resource Collection and Data
Collection of Pine Trees –Data analysis and report
preparation – Area Selection and Environmental Study.
Tree Enumeration– Procedure of counting the Tappable
Trees. This work is repeated in every 05 years.
Blocking- Blocking the Pine forest average 10,000 trees
are kept in one compartment and each block divided into
sub block ,one sub block is provided for one worker for
tapping.

9. Bark Shaving– The loose and rough bark over a surface
area about 45cm x 30cm above 15cm from the ground is
removed with the bark shaver leaving 02mm thickness.
Marking the Position of Blaze and Groove – The Blaze
frame is vertically fixed on the bark shaved surface leaving
15cm above the ground and position of the blaze frame
marked with the marking gauge.
Cutting the Central Groove- A central groove 4mm
deep and 7-9mm wide is made with the help of central
groove cutter.

the rill method

11. Tapping rills calculation
One week = 01 rill
One month =04 rills
One season(08 months) =32 rills
 After two years tapping the blaze reaches a
height at which it is not possible to pull the
freshening knife upwards.
 The blaze can be extended up to 04 years
during the fifth year the height will be beyond
the reach of the tapper.
 During the sixth year a new blaze is made at
the bottom of the tree in the same manner as
in the first year and continued this process
upto 20 years

13. Fixing the Lip and Resin Pot– Lip should be fixed
properly with nails & iron wires and ensure that proper flow
of resin into the pot
Freshening – Tapper should stand near the tree on one side
of the blaze and hold the freshening knife at the lowest
point of the central groove .Average width b/w consecutive
rills is 6 to 7 mm and depth 2mm.
Treating the Blaze with Stimulant - A chemical
Stimulant used is a mixture of 1:1 ratio (20% dilute sulphuric
acid and dilute nitric acid) should be sprayed on the freshly
cut rill through sprayer .

14. Live Demonstration of Rill Method Tapping
Tapping Season-
start on 15th March to 15th October (07 months in colder localities )
and
upto 15th of November (08 months in Warmer localities )

15. Collection of Resin & Cleaning the Groove
Remove resin pots from
trees and thoroughly
removed resin from the pot
with the help of scrapper
and collected in the
collection can .
Central Groove is cleaned
after each collection with
groove cleaner to facilitate
smooth running of fresh
resin to the pot.

16. Benefits of Rill Method
Minimum Cutting that save heart wood from the
damage and does not reduce the economic value of
wood.
Fast healing of blaze reduce the tapping cycle and
increase tapping life of tree and forest.
Provide safe from the fire and wind comparatively.
It generates more employment due to 08 months
tapping period and then transportation period .

18. Introduction
Family – Verbenaceae . Local name – Panchphuli.
Lantana Camara is native to the Tropical & Sub-Tropical
regions of Central & South America .
In India it was introduced in the early 18th century as an
ornamental plant in Coorg , Dehradun and Kolkata.
Now 3.2 million hectares besides forests and fallow land is
fully covered with this weed Lantana Camara

19. Lantana Infestation – a growing problem
One of the world’s 10 worst invasive species –
declared a problematic weed in about 60 countries
 Introduced in 1807 as an
ornamental plant
 Infests 44% of forest area
(about 3,00,000 sq. km.)
In India
 About 2354.9 sq. km. area infested
with Lantana
 Mostly found in subtropical forests
below 1000m altitude
In Himachal Pradesh

20. Challenges for Managing
Seeds extremely viable – can remain dormant for 10s of
years.
Extremely versatile – adapts to climatic and edaphic
conditions.
No natural competition.
Produces large amount of seeds every year.
Has good coppicing ability.
Ability for vegetative propagation from root stock, air
layering.

21. Kudali (Hoe)
Y- shaped Stick or
Bamboo
Gainti (Pickaxe)
Tools used for CRS Method

22. Involves cutting the main tap root of the Lantana plant
below its coppicing zone.

24. Live Demonstration of lantana eradication

25. Precautions before Removing Lantana
 Simultaneously clear all the small/new Lantana plants.
 Not to break the branches .
 Strike the base of the root by kudali as close as possible
to avoid soil disturbance.
 Other desired species should not be damaged.
 If there is large birds perching trees, clear the Lantana
periodically from such sites.

26. In three seasons:
July-August
October-November
March-April
Good Time : After First
Summer Rain Showers in July-
August
The soil becomes soft
Easier to cut the root stock
Right Time to Remove Lantana

27. Demonstration of removal of
Lantana by CRS method

28. Putting clumps of grass in the pits.
Manual grass propagation. Preferably
fast growing shrub/grass.
Broadcasting seeds by dibbling or
pellets.
Planting of native species.
Restoration of Lantana
Cleared Areas

29. Uses of cleared lantana
 As fuelwood – dried Lantana can also be used to
charcoal making
 Production of handmade furniture such as stools,
chairs, mats etc.
 Use of dried leaves as mulching agent
 Biogas production

30. Benefits of CRS method
Uprooting exactly below the
transition zone (4 inches) eliminate
the possibility of reproduction
capacity.
Minimum disturbance of soil.
Minimum damage to other flora and
flora species .
About 60% less manual efforts
compared to cutting/slashing.
