Extension - வன விரிவாக்கம்

According to National forest policy at least 33% of the total geographical area of the country should be under tree / forest cover to improve eco-system.  As there is no scope to increase forest area, thrust has been given to increase tree / green cover outside forests.  It is imperative to expand our tree resources outside the natural forest area to meet the ever-increasing demand of the forest produce. 


In Tamil Nadu Forestry Extension activities are being carried out through Forestry Extension centers established in all the Districts. These Centers are mandated to

  • Transfer the improved technology of tree cultivation to farmland, motivate the people to take up tree planting and provide platform for Eco-education.
  • To expand our Forest/ tree resources outside natural forests, thereby increase the tree cover to 33%of total geographical area of Tamil Nadu.
  • To increase the tree cover in urban and rural areas by massive tree planting to mitigate pollution.
  • To create awareness among the public, especially youth and school children, about the values and importance of trees and forests.
  • To generate employment opportunities among the educated youth and more particularly in rural people and thereby increase their economic status.

Forestry extension centres provide technical support for tree growing in rural areas through 30 forestry extension centres in Tamil Nadu. These centres provide quality tree seedlings like thornless bamboo, casuarina, teak, neem, Melia dubia, grafted tamarind, nelli, etc. to the farmers.  These seedlings were planted in private lands.  These lands have become demonstration plots.  During 2012-13, forestry extension wing was trifurcated it into three regions viz. Chennai (North), Salem (Central) and Madurai (South) functioning under the control of Chief Conservator of Forests.


The forestry extension centres in the districts were formed to interpret the planting techniques and uses of trees, medicinal plants, fodder and to create awareness about the importance of forests among the public.

Training on tree growing

  • Publicity and propaganda

Training has been organized for the farmers by the FE division personnel and by inviting resource persons/ subject matter specialists. During the training program, the farmer trainees have been made aware of various improved technologies of tree growing and post harvest technology practices and also motivated to take up tree planting. Hands-on training on various income generation activities like Tree cultivation, Medicinal plant cultivation, Vermi-compost and VAM production etc. have also been imparted to rural womenfolk and Self Help Groups.


Highlighting the importance of forests has been imparted to the youth and children.  Publicity boards, charts, posters etc., have been prepared and displayed at vantage points. Exhibitions have been organized by displaying models, charts, posters etc., in places of public gathering.

Demonstration (on farm trials):

Demonstration is an acknowledged method of sensitising people about the value of improved tree cultivation practices. Fast growing, high yielding and drought tolerant tree species like thornless bamboo, Casuarina junghuhniana, Ailanthus excelsa, Melia dubia etc. have been introduced to the farming communities through this activity. In addition to the above, high quality tree seedlings and grafts have been sold to public at 50% subsidised rates for planting in their fields.

 Vermi casting and VAM production

 Vermi-compost and VAM production structures have been established. The SHGs and the individuals interested in taking up Vermi-compost production as an activity have been given training on the various aspects of Vermi-compost production. The Vermi-compost and VAM produced in the Extension centers is being used for departmental purpose for time being.

Moreover, notices and brochures containing the details related to tree growing have been distributed to the public.  Publicity boards with the details related to tree growing have been also prepared and installed in highways to create awareness among the public about tree growing.        

Tree Growers Society

At present, the number of persons receiving technical support from the Forestry extension centres are kept increasing.  The Forest department is actively involved in formation of Tree Grower's societies in various districts.  Now, Tree Grower's Societies formed in Tiruvannamalai, Pudukkottai, Coimbatore, Cuddalore, Villupuram and Sivaganga districts are effectively functioning. 

            All measures have been undertaken to increase forest / tree cover of Tamil Nadu by involving local people in tree growing activities, vermi-compost production and environmental conservation through these forestry extension centres.
