STATE FOREST RESEARCH INSTITUTE

Forest research in Tamil Nadu commenced in 1918 and the first Annual Research Report was published in 1919. Since then research activities are mainly focused on various thrust areas based on field requirements from time to time. Research Unit in Chennai formed much before Independence had carried out Research in the cultivation of important trees like Teak, Jack, Terminaliatomentosa, Terminaliapaniculata, Dalbergialatifolia, Gmelinaarborea, etc.

The thrust of current forestry research activities is on reducing pressure on natural resource by increasing productivity through genetic and silvicultural improvement, making available technical know-how for agro forestry, wasteland development, eco-restoration and conservation of forest eco-system.

With a view to increase availability of high quality planting material of economically important tree species for afforestation and reforestation of degraded forest and take up large scale tree cultivation in private lands, the research wing has established seed production areas, clonal seed orchards, seedling seed orchards and hedge stool in various research centres in Tamil Nadu.

Micro and macro propagation for economically important and fast growing species like teak, sandalwood, silver oak, Melia dubia, Ailanthus excelsa, Eucalyptus, Casuarina has been standardized and propagules are being given

It is essential to select different candidate plus tree species for different characteristics. Seedlings raised from these species will have superior genetic characteristics. Seeds are being collected from the plus trees to raise high quality seedlings. Work of marking GPS location of each CPT was continued and about 500 CP trees thus identified with reference to different species.

BIO-DIVERSITY CONSERVATION

More than 30 plus trees were selected in Tamil Nadu which had high  heartwood,  oil and santalin content, during genetic combing of sandalwood in the year 1982-83 Germplasm bank consisting of 35 plus tree of sandalwood was established at Salem Research  Centre during 1983-84.  This is one of the very first Sandal Clonal Bank establishedin India.

Improvement of Sandal through grafting and creating Sandal Germplasm Bank

The heart wood being the most valuable part of sandal wood  clonal Germplasm Bank of sandal wood were established by taking scion from identified plus tree having high proportion of Heart wood, oil and santalin  content  and grafted seedlings were raised for establishing clonal germplasm  bank of sandal.

Mass multiplications of medicinal plants which are in high demand are as follows:-Bixaorellana, Caesalpiniasappan, Cissusquadrangularis, Santalum albumandWithaniasomnifera.

 

Cissus quadrangularis                                   Withania somnifera

 

Research on Coastal area afforestation :

            Tree species suitable for coastal areas as bio-shields were identified as Acacia auriculiformis, Erythrinaindica, Casuarinaequisetifolia, Casuarinajunghuhniana, Hibiscus tiliaceus, Cassia siamea, Kaya senegalensis, Salvadorapersica could be produced in forest nurseries.  These can be used to form plantation in coastal areas for wind breaks and increasing greenery. Prosopis has been tried for afforestation in lantana infested (now removed) coastal areas during 2014-15 by planting Thespesiapopulnea, Dalbergiasissoo, Hibiscus teliaceous, Borassusflabellifer, Tecomellaundulata, etc. in coastal area at Thangachimadam (R) Centre of Rameswaram (R) Range.

 

Research on Sand dune stabilization:

            For stabilization of sand-dunes and to improve the quality of soil, suitable tree  species like Bassialatifolia, Derris indica, Polyalthiapendula, Eucalyptus species, Coccolobauvifera, etc. were planted.  The same programme is being continued.

 

Research on afforestation of problem site:

            Experiments have been laid with various species in problem sites viz. saline-alkaline soil, sheet rock and bouldary sites, magnesite mine dumps, etc. and the suitability of various species is being assessed. Work of afforestation in sheet-rock and boulder areas mostly with Ficus species was continued in different areas both inside and outside research centres. Appropriate species and techniques for problem soil afforestation especially rocky areas, mine-spoil areas, etc. will be identified for transfer of technology to the Forest Department.

Research on Fuelwood :

            Around 30 species were selected and tried for production of biomass and fuel wood under different espacement and protective irrigation regime.  It was previously found that Casuarina, Albizziarichardiana, Hibiscus tiliaceous, Samaneasamanare suitable for energy production in gasifier. During 2014-15, Acacia auriculiformis, Acacia mangium, Leucenaleucocephala, Prosopisjulifloraetc. were tried for electricity production in bio-gasifier to see their suitability. Similarly different species (grass, bamboo, etc.) were tried for briquette making to see their efficacy in terms of calorific value, etc. During 2015-16 Morusalba, Azadirachtaindica, Albiziaamara, Acacia hybrid, Leuceanaleucocephala, etc. have been taken up with different espacement trials.

SOIL NUTRIENT MANAGEMENT

ANALYSIS OF FOREST SOIL

Any soil that has developed under the influence of a forest cover, commonly referred as forest soil.

Forest soil posses distinct characters than the normal soil even though they have developed from the common parent material and under same climatic conditions.

• Unique effects of deep rooting by trees
• Specific organism associated with forest vegetation
• litter layer and leaching promoted by the products of its decomposition of soil genesis

 

About 500 soil samples, collected from all the districts, were analysed for N, P, K, Ca, Mg and Micronutrients like Zn, Cu, Mo and Bo etc. The irrigation water samples sent by the farmers were also analysed for Electric Conductivity (EC) and Residual Sodium Concentration (RSC) etc. in Soil science laboratory, State Forest Research Institute, Kolapakkam, Chennai

SILVICULTURE

Introduction trials

            Research plots are there in various agro-climatic zones of Tamil Nadu. Plant species, which are not found in certain areas, have been raised in introduction trials in our research centres. Introduction trial of Prosopis cineraria, Adina cordifolia, Adansoniadigitata, Salvadorapersica, Brideliaretusa, etc. was taken up. Introduction of Thespesiapopulnea, Dalbergiasissoo, Hibiscus teliaceous, Borassusflabillifer,etc. has also been undertaken in coastal area infested with Prosopisjuliflora.

NURSERY EXPERIMENTS

Different culling methods, Bio-nutrient – Bio-fertilizer inoculation, juvenile – adult relationships were carried out in the nursery stages that paved way for ensuring enhanced bio-mass productivity.

RESEARCH ON BAMBOO

            45Bamboo species were identified for planting in Tamilnadu. Among these B.nutans, B.tulda, B.balcooa, B.vulgaris are found suitable for profitable cultivation. It is proposed to collect and assemble another 10 Bamboo species at the Bambusetum at Amravathi during 2016-17.

Bamboo setum at Amaravathy Research Centre

 

            Bamboo has been used as a reinforcement material partially replacing steel in cement concrete and structure is under evaluation for its strength and durability. Bamboo reinforced bus shelter using bamboo with RCC as also bamboo composites has been designed for new trial during 2014-15. The cost of various bamboo products is less than comparable products. To take an example for a ‘Slab’ of dimensions 90cm X 90 cm X 7.5 cm, Cost of slab with iron rods as reinforcement is Rs. 464 while that of bamboo is Rs. 386 (16.73% reduction in cost). Model eco-friendly bus shelter with bamboo has been erected showcasing use of bamboo to the public.

Research on species suitability for Timber, Plywood & Veneer   :

            Plywood and Veneer are in more demand due to their wide usage. It is better to use them rather than traditional timber species having long rotation period.  So experiments are being carried out with Acacia hybrid, Silver oak, Hopeaparviflora, Alstoniascholaris, Dysoxylummalabaricum, Kaya senegalensis, Ailanthus excelsa, Albiziafalcatoria, Heveabraziliensis, Ailanthusmalabaricum for profitable cultivation in Research Centres and in private lands. During 2014-15, immature timber of different species such as Anthocephaluscadamba, Gmelinaarborea, Albizzialebbeck, Pterocarpusmarsupium, Lanneacoromandelica, etc have been seasoned and are being tested for wood properties.

Further studies on wood properties, their suitability for wood products, plywood/ veneer, etc. was taken up with the assistance of organisations like IWST. Samples of Kaya senegalensis,Meliadubia, Lanneacoromandelica, Anthocephaluscadamba, Gmelinaarborea, Artocarpusintegrifolia, Albi
