2Introduction
- Forest plantation is the best alternative for
timber requirement of country. - Protection production and research are main
purposes in FP establishment. - Mahogany Jak mixed forest plantation plays mainly
production purpose. - Both species are an exotics, which are
naturalized later on . - Mahogany is introduced by Dutch in later part of
18th century, an avenue plant in Jaffna district. - Forest department used this species for
plantations mixed with Jak ,Teak,Mesua etc.
(Degraded Natural forest specially in
intermediate zone)

6- This plantations provide many direct indirect
benefits - Direct benefits
- Timber (Jak and Mahogany),
- NTFPs (Fuel wood, Medicinal plants,
Binding materials (Rottan Bata),Edible Fruits
(Jak,Goraka), Green Leaves) - Indirect benefits,
- Source for carbon storage ,
- Provide the habitat to fauna flora ,
- Responsible for microclimatic stabilization,
- Provide recreation purposes Scenic values,
- Reduce soil erosion,
- Increase rain water infiltration recharge
ground water table.

8- Main Objective
- Carry out a cost benefit analysis for Kotakanda
- Jak /Mahogany plantation.
- Other objectives.
- Estimate economic value of various products
provided by the forest plantation. - ( a) Estimate economic value of NTPFs the
adjacent community. (Local marketer price)
- ( b) Estimate of economic value of timber
benefits provided by the forest. (mainly
mahogany timber using by - CIF value)
-
9Methodology
- Collect primary and secondary data to estimate
economic benefits for Jak /Mahogany plantation. - Primary data
- Household survey on adjacent 4 GN Divisions
local market to forest plantation. (Pohonoruwa,
Handurumulla,Kaleliya Pallewela and Palmadagama)
Using a structured questionnaire. - Target group was 90 house holders. Sample was
selected by random sample method. - Gather expert opinions from
- F.D. (SDCF, DFO, RFOs, BFOs in Forest
inventory management) - STC other related parties( Divisional
secretarial, Grama niladary, Custom officers )
10Study area
Pohonoruwa
Handurumulla
Palmadagama
Kaleliya/ Pallewelaa
11- Secondary data
- ? Collected secondary data from Forest
Department, State Timber Cooperation relevant
agencies and published importations. - Yield table,
- Inventory manual,
- Mahogany management plans
- Custom Reports statistics
- Conversion factors
- Other published und unpublished
- eg. Research papers, Thesis, to
relevant this study
12- Data analysis
- Collected primary data
- Converted quantity of NTFPs components to
monetary values (Local market price). - Improved financial values to economic values
using conversion factors. - Converted timber volume to monetary values using
import parity price (CIF). - Analyzed all collected costs and benefits in a
CBA frame work using a 10 discount rate (NPV,IRR
and BCR). - Done sensitivity analysis (20 cost increased,
20 benefit reduced and both condition apply
together) -
13- Costs
- Plantation establishment cost (Enrichment
Planting cost) - Maintains cost (Nursery practices, Vacancy
Filling, Thinning, Creeper cutting) - Over head cost (FD)
- NTFPs extraction cost (Adjacent community)
-
- Benefits
- Direct - Timber (Mahogany )
- - NTFPs (Fuel wood, Medicinal
Plants, Green Leaves, Fodder,
Binding material, Fruits)

17Findings
- 9 GNDs are surrounding this Forest Plantation.
- (Henepola, Palewela/Kleliya, Handurumulla,
Hapitigama, - Pohonnoruwa, Lindara, Palmada Idiparape)
- More than 75 villages are extracts fuel wood
from plantation. - Other utilities- Jak fruits, fodder, medicinal
plants, binding material, water. - Local community use natural water by streams
origin from forest (for bath, washing
,agriculture and specially drinking purposes). - Main income depend on agriculture. 5 of house
holders are Government Private sector
occupations. - 68 sumurdi beneficiaries. Relatively low
income generators are there. - 99 house holders are directly or indirectly
depend on this forest plantation.
18- Annual direct net benefits
- The highest NTFPs utilizing GND is Palmadagama
and - Kalelliya Pallewela is lowest consume GND.
- Fuel wood is main consume NTFPs component.
- More than 90 adjacent community depending
natural water resources for their daily needs
from the forest plantation.

20Conclusion
- Annual NTFPs benefits is Rs 5,341 per ha per
family.56 of NTFPs provided from fuel wood and
21 Binding materials. - Annually Rs 518,633 conserve to country national
income by 1ha Mahogany plantation. - IRR(26) is grater than discount rate (10) in
economic analysis. - NPV is positive at different discount rates
(5,15 20) BC ratio grater than 1. - According to the present study can be shown
Kotakanda mix forest plantation provides high
economic efficiency.
21Discussion
- Issues of Methodology
- Obtained data may not be very accurate, due to
several reasons absence of elder people in
families and unwillingness to give real
information. - There may be seasonal variation of NTFPs. (survey
was done in March 2008.) - Increased accuracy of estimation adjacent 9 GNDs
are included in that sample. - Estimate NTFPs and timber benefits based on
several assumptions. - Estimate timber benefits used in CIF values.
- Estimate only direct benefits provided from the
forest plantation.
22Recommendation
- Policy reorientation.
- Empower forest dependent to adjacent people.
- Improve harvesting, storage, transport,
processing manufacturing methods to NTFPs - Improve technologies of utilization of NTFPs.
- Implement domestication and cultivation.
- Focus to research and development further
indirect benefits and total economic values. - Promote mix Mahogany plantations in small scale
on home garden and private land. - Enhance private sector involvement to planting
Jak/Mahogany mixed species.
