Recognising the potential of bamboo, and its contribution to economic growth and socio-economic conditions of the rural poor, a National Bamboo Mission was formulated by the Planning Commission and now stands approved by the Government. Department of Agriculture & Cooperation, Government of India will implement the Centrally Sponsored Scheme of National Bamboo Mission, for the holistic development of the bamboo sector in the country with an outlay of Rs. 568.23 crores. The National Bamboo Mission (NBM) programme in West Bengal started during 2007-08 and is continuing through 2008-09 and 2009-2010. The NBM funded programme has been undertaken with an objective to increase the coverage of area under bamboo with suitable species to enhance yields, as well as to generate employment opportunities. In the forest areas of West Bengal the bamboo programme has been undertaken through the Forest Development Agencies and the Joint Forest Management Committees (FPCs) to establish nurseries to raise bamboo seedlings and to raise high-yielding bamboo plantations. In the present Monitoring & Evaluation report, survival and growth of the bamboo plantation raised in 2007-08 in five Forest Divisions, one in North Bengal [Darjeeling Division] and four in South Bengal [Purulia, Kangsabati-I, Durgapur & Panchet Soil Conservation Divisions] West Bengal has been shown. The % composition of different bamboo species has been shown in each cluster of bamboo plantation. Also the Nurseries of respective bamboo species have been inspected and evaluated in terms of the fixed norms and the results tabulated in the report. This report is the result of the hard work put up by Dr. Kana Talukder, IFS, Conservator of Forests, Monitoring Circle, with the support and suggestions of other officers as well as that of the staff of Monitoring Circle. My sincere thanks and acknowledgement are due to all of them. Sd/ D. Biswas, IFS Chief Conservator of Forests, Monitoring, Evaluation & Soil Conservation, Government of West Bengal. Bamboo Monitoring Report 2007-08 3 Overview: Bamboos were planted over 30 hectares on forest land in five divisions of West Bengal during 2007-08 under the aegis of National Bamboo Mission (NBM). After more than one year, it was found that the survival percentage of these plantations ranged from about 32% to 100%. Also, during 2007-08 Central bamboo nurseries were raised in five Forest Divisions with nine species of bamboos as recommended by the NBM. Plants were either of seed-origin, or were raised from rooted nodal cuttings or from the rhizomes. For the first time the Monitoring Wing of the Forest Directorate, Government of West Bengal undertook a 100% species-wise survey in respect of survival and growth of these bamboos. This Report presents the synopsis of the findings along with a few recommendations. A model format for record keeping in bamboo nurseries has also been provided for reference. Economic Importance of bamboo: Bamboo is an important Non Timber Forest Produce (NTFP) of West Bengal. Bamboo has versatile uses as building material, paper pulp resource, use in making scaffolding, agriculture implements, fishing rods, weaving material, and as substitute for rattan, plywood and particle board manufacture. Pickled or stewed bamboo shoots are edible and are regarded as delicacies. Bamboo is a good soil binder owing to its habit of clump formation and presence of fibrous root system and hence also plays an important role in soil and water conservation. Bamboo roots, leaves, sap and ash have use in Ayurvedic health care system. It is grown like any other horticultural crop by tilling the land and is harvested annually, when grown commercially. The major user of bamboo in India is the paper industry, which consumes sizeable proportion of the total annual bamboo production. India has the second largest bamboo reserve in the world after China but exploits only one-tenth of its potential. A National Bamboo Mission has been formed to promote the growing and processing of bamboo. National Bamboo Mission Programme in West Bengal: The National Bamboo Mission (NBM) programme in West Bengal started during 2007-08 and is continuing through 2008-09 and 2009-2010. The NBM funded programme has been undertaken with an objective to increase the coverage 4 Bamboo Monitoring Report 2007-08 of area under bamboo with suitable species to enhance yields, as well as to generate employment opportunities. In the forest areas of West Bengal the bamboo programme has been undertaken through the Forest Development Agencies (FDAs) and the Forest Protection Committees (FPCs) to establish nurseries to raise bamboo seedlings and to raise high-yielding bamboo plantations. The main objective of plantation development component of the programme is to increase productivity with commercially important bamboo species to supply shoots on regular basis to processing units for manufacture of more value-added products. For raising the high-yielding plantations of bamboo, it was envisaged that a sizable quantity of quality planting material of recommended species of bamboo would be necessary. In the forestry sector centralized nurseries have been set up, established by the West Bengal Forest Directorate. Land is being identified each year for raising bamboo plantations in government forest lands. Planting scheme is to be chosen taking into consideration the size and growth habit of the selected species. The total cost of planting bamboo in one hectare of government forest land was worked out to be Rs 25,000 (including third year maintenance) while Rs 2.73 lakhs (one-time grant) was sanctioned per centralized nursery for raising planting materials in forest areas. Monitoring criteria Different criteria were fixed for monitoring of central nurseries and of bamboo plantations. Criteria for Monitoring of the nurseries: 1. Whether Bamboo species raised conformed to the list suggested by the NBM? 2. Whether the total number of plants per nursery unit was 50,000 per year? 3. Species-wise number of plants raised, disposed and remaining in stock. 4. Mode of bamboo propagation, whether 2-node cuttings, rhizomes or from seeds? 5. Status of nursery journals and other deficiencies, if any. Bamboo Monitoring Report 2007-08 5 Criteria for monitoring of bamboo plantations: 1. Whether the species planted were as per selected list given by NBM? 2. Species-wise survival percentage. 3. Species-wise growth. 4. Status of plantation journals and deficiencies, if any. Monitoring methodology & data calculation: Field monitoring works were undertaken during the period from December, 2008 to March, 2009. In this regard knowledge of the field staff and FPC members relating to the local vernacular names of the bamboo species were relied upon and cross checked with available records for ascertaining the Latin names. In nurseries, the beds and plants in stock were counted and cross checked with the records. In plantations, all the surviving bamboo plants were counted (total enumeration) and cross checked with the plantation journals. Data was tabulated species-wise and percentage composition of the surviving population was calculated. It was found that by and large bamboo was planted at a spacing of 4 metres x 4 metres which works out to 625 plants per hectare. However, the prescription as recommended by the NMB guidelines was 4 metres x 6 metres, which means 417 plants/ ha. This has been decided to be adhered to 2008-09 onward. In this Report the Survival Percentage (SP) of the overall plantation has been reported as actually found in field, vis-à-vis stocking of 625 plants/ ha being taken as 100%. 6 Bamboo Monitoring Report 2007-08 Monitoring constraints: This is the first time a species-wise monitoring on bamboos has been undertaken by the Monitoring Wing. The work involved in identification of bamboo species is a very specialized job and requires considerable taxonomical and morphological knowledge. It was also noticed that there is much confusion and variations in local names of the same bamboo even between neighbouring districts. Identification has been restricted to gross morphological characteristics of individual bamboo species. Utmost care has been taken to segregate data specieswise, but the possibility of human error in identifying the species in the field can not be ruled out. Accumulation of dust on bamboo leaves in roadside plantations, such as in Riyang-5 of Darjeeling Division, also interfered with species identification. In the current survey there was no scope of taxonomic identification based on advanced methods such as DNA analysis. The whole of South West Bengal in general and Purulia in particular has reported drought–like conditions with no rainfall occurring since last monsoon. This has induced high mortality. Though it is possible that the bamboo rhizome is still surviving, lying dormant underground, the portions of the shoots above ground were found to be often leafless and brown. In such cases determination of SP is prone to errors. The guidelines of the NBM necessitated evaluating the number of FPCs and Self Help Groups (SHG) formed as well as their details of beneficiaries, genderwise membership and the extent of participation in the trainings. Such information in the manner as required by NAM was not available with the Monitoring Wing. Such committees and groups were formed with wider scope. However the concerned territorial divisions may be requested to compile such data for future years. The format is available in the end of this Report.

Infilling had been done with node cuttings from Balarampur nursery. The area is hilly, drought prone and subject to erosion. Soil is generally poor. There is also high termite infestation which is resulting in high seedling mortality. Uprooting of some dead seedlings showed that termites had completely eaten away the fibrous root system before attacking the core of the bamboo culm. Repeated pest control measures need to be adopted. Height varied from 0.3 metres to 3.5 metres. 22 Bamboo Monitoring Report 2007-08 Status of Purulia plantation: Species # of plants of rhizome origin # of plants of seed origin # of plants of node-cutting origin Total # of plants % composition B. balcooa 0 0 0 0 0 B. bambos 0 0 0 0 0 B. nutans 0 0 0 0 0 B. vulgaris 0 0 0 0 0 D. hamiltonii D. strictus 0 0 0 0 0 1032 0 0 1032 100 M. baccifera Total 0 0 0 0 0 1032 0 0 1032 100 Critical Analysis of Bamboo Plantations Raised during 2007-08: (1) There have been reportedly no rains since last monsoon. This has adversely affected the survival percentage. Soil, particularly in Purulia district, is generally poor in nutrient contents and is also subject to erosion. In addition there is some termite infestation. It is believed that these may have contributed to some extent towards the low overall survival percentages in Purulia and Kangsabati North Divisions. (2) Additional pest control measures repeated periodically need to be adopted in places where termite infestation is high. NBM guidelines allow fund provision for pest and disease management in plantations. Suitable proposals may be initiated in this category. (3) Soil conservation measures are required to be undertaken well in time to stop further depletion of top soil and damage to plantations. (4) During monitoring tour the undersigned found that survival and growth of seedlings raised from nodal cuttings is generally better than that of rhizome or seed origin plants. (5) Rhizome availability and collection was reported by the DFOs to be somewhat erratic and also substantially expensive. Existing bamboo clusters, whether in villages or in forests, are damaged during collection of rhizomes and hence this practice is not recommended. Bamboo Monitoring Report 2007-08 23 (6) B. balcooa has performed excellently in Durgapur Division and Panchet Division, where all of the surviving plants attained height of more than 150 cm in 2 years. B. vulgaris also performed well, majority of the surviving plants reaching a height greater than 150 cm in 2 years. In the more arid Purulia and Kangsabati North Divisions, D. strictus seems to be currently the viable option. (7) Bamboos are seen growing naturally in the hills of districts of Purulia and Darjeeling. A survey is needed to identify the bamboo species occurring wild locally, so that efforts may be made to propagate them for raising plantations in future. (8) Survival percentage is very high for Darjeeling Division. However it is also evident that spacing had not been maintained as per prescription. According to the DFO Darjeeling Division, infilling had been carried out after some mortality was noticed. Resultant plantation has very high crop density but erratic spacing. (9) In Panchet Division also the spacing is not exactly as per prescription. According to the DFO Panchet Division, advance work in field had aimed for a 3 m x 3 m spacing, which was later modified to accommodate the bamboo model. (10) The First Working Plan of Burdwan which includes Durgapur Social Forestry (SF) Division is ending in 2009 and it is understood from D.F.O. Durgapur SF Division that the first Preliminary Working Plan Report (PWPR) has been submitted. The First Working Plan (valid from 1989 to 2009) had recommended a rotation of 4 years for bamboo (ref. pg 15 of volume 2) planted in blocks under Development Working Circle. In the new working plan bamboo harvesting schedule should also be clearly specified. (11) The current Working Plan for Purulia which include Kangsabati North Division & Purulia Division (2nd revision of 1st Working Plan valid from 2008-09 to 2011-12) recommends that “bamboo should be given priority at the time of raising plantation” (ref. pg viii of Volume 2) in Development Working Circle. However, no harvesting schedule has been specified which needs to be taken up with appropriate authorities in view of the large scale bamboo plantations being envisaged under National Bamboo Mission. 24 Bamboo Monitoring Report 2007-08 (12) The current Working Plan for Bankura which includes Panchet Division (2nd revision of 2nd Working Plan valid from 2008-09 to 201112) recommends that “bamboo should be given priority at the time of raising plantation” (ref. pg viii of Volume 2) in Development Working Circle. However, no harvesting schedule has been specified which needs to be taken up with appropriate authorities in view of the large scale bamboo plantations being envisaged under National Bamboo Mission. (13) The Working Plan of Darjeeling (valid from 1997-98 to 2017-18) lays down rules for felling of bamboo (ref. pg 80 of volume II & IV). Only mature culms are to be felled and each clump of bamboo to be given a three years’ period of rest after each felling. It recommends that earth should be put in bamboo clumps to cover the roots and rhizomes in March. These rules as applicable may be practiced elsewhere also. (14) Since bamboo is considered to be an NTFP and it is technically a grass, it may be argued that existing JFM rules and regulations assuring royalty-free collection by FPC members legally apply to bamboo collection also. In this context reference is made to Clause 4 of Government of West Bengal, Forest Department, Forest Branch Resolution No.2759-For dated 17.4.2008 …“The members shall be entitled to collect following items free of royalty without causing any damage to forest/plantations (a) Fallen twigs, grass, fruits, flowers, mushroom seed (excluding cashew) etc and leaves”. Special order may be formulated relating to bamboo harvesting on the lines of collection of cashew, honey and bee-wax. (15) Efforts and progress made in bamboo propagation by different divisions may be dovetailed to share information and reduce duplication and redundancy. Bamboo Monitoring Report 2007-08 25 2.

Remarks: Nursery register was found to be maintained. Bamboo was collected from Matha Chulka, Bidhannagar and Dhupjhora villages. Bamboo cuttings with two nodes were raised in 78 layered mother beds. Cowdung manure, leafmould, NPK and vermicompost were used. In addition, naked rooted seedlings were raised in 10 beds. B. vulgaris responded to propagation by node cuttings. Attempts to raise B. balcooa through node cutting did not succeed. To enhance root growth and avoid mortality under prevailing arid conditions, the potted plants have been kept in the green house of the Chalsa Central Nursery located in the Range Office premises. Bamboo plants have not yet been disposed. 30 Bamboo Monitoring Report 2007-08 Status of Chalsa Nursery: Species # of plants of rhizome origin # of plants of seed origin # of plants of nodecutting origin Total # of plants raised B. balcooa 0 0 0 0 B. bambos B. nutans B. vulgaris 0 0 0 0 0 0 0 0 9000 0 0 9000 D. asper D. giganteus D. hamiltonii D. strictus M. baccifera Total 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 9000 9000 Table 2.3C: Division: Kangsabati South.

Nursery journal status: The nursery journal has been maintained in detail and reflects regular visits by officers concerned. All financial data have been entered and record maintenance is excellent. Format of the nursery journal as maintained at Taipu is given at the end of this Report to serve as a guide for other similar nurseries. Remarks: 155 nursery beds were made. Seeds were procured from Prem Nursery, Dehradun. Among the five nurseries created during 2007-08, this nursery alone has attained the target of producing 50,000 plants per year. The nursery staff is well conversant with the different species of bamboos in stock. Given that they have been able to proliferate through node-cuttings six species of bamboo, which is a highly technical job, it is suggested that 32 Bamboo Monitoring Report 2007-08 staff connected with this nursery may be used resource persons to impart training in this mode of propagation of bamboo in other nurseries.

Remarks: From the nursery register it was seen that 100 beds have been prepared for node cuttings which included 75 layered brick beds and 25 mother beds in which 11,400 seedlings were raised. In addition around 3,000 cuttings have been separated from the nodal clusters and raised in polypots. Watering is being done twice a day and no agro shed net is being used. The nursery supplied plants for 10 ha. of bamboo plantation raised by Panchet Division during 2008. 34 Bamboo Monitoring Report 2007-08 Status of Joypur Nursery: Species # of plants of rhizome origin # of plants of seed origin # of plants of nodecutting origin Total # of plants raised B. balcooa 0 0 4800 4800 B. bambos 0 0 0 0 B. nutans 0 0 0 0 B. vulgaris 0 0 1650 1650 D. asper 0 0 0 0 D. giganteus D. hamiltonii D. strictus 0 0 0 0 0 0 0 0 0 0 4950 4950 M. baccifera Total 0 0 0 0 0 0 11400 11400 Species-wise % composition of plants raised in bamboo nursery of Panchet Division D. strictus 44% B. balcooa 42% B. vulgaris 14% Critical Analysis of Bamboo Central Nurseries Raised during 2007-08: Bamboo Monitoring Report 2007-08 35 1. It was found that layered brick edged beds in nursery with watering twice a day lead to prolific root and rhizome production from nodecuttings. With some variations, the basic model of such a bed involves making the lowest layer of boulders with every succeeding layer being composed of finer materials finally topped with sand. The design facilitates rapid water percolation and prevents root rot. 2. Use of agro shed net, sprinkler irrigation or misting reduces seedling mortality in the nurseries located in more arid areas. 3. NBM guidelines envisage identification of a suitable Certifying Agency to ensure supply of quality planting material. This needs to be followed up for species / quality certification because considerable confusion exists in the field relating to correct taxonomic identification of bamboo being used in propagation. 4. Nursery journals were not maintained in the field during 2007-08 except in NTFP Division. Chief Conservator of Forests, Central has introduced a journal format for use in nurseries from 2008-09. A model bamboo nursery journal format based on these two journals is included at the end of this Report for reference for similar nurseries elsewhere. 5. Propagation by the node cutting method requires considerable technical expertise. During monitoring it was found that staff of Taipu Nursery (Sri D. R. Raha, FR, Range Officer Siliguri NTFP Range and local Head Forest Guard Sri D. Shah) has developed practical knowledge relating to node cutting of six bamboo species. Their expertise may be used to conduct training in propagation methods for these species. 36 Bamboo Monitoring Report 2007-08 Key Recommendations: 1. Monitoring data indicates generally excellent performance of B. balcooa and B. vulgaris in Panchet & Durgapur Divisions, and hence are recommended species for these areas. 2. Survey of bamboos in Purulia & Darjeeling hills needs to be undertaken for screening of suitable bamboo species to be raised locally in plantations to improve success rates. 3. Method of using layered brick edged bed in bamboo nursery is recommended for reducing root-rot and facilitating profuse rooting of node cuttings. 4. A model bamboo nursery journal format has been annexed to this Report for reference in record keeping in nurseries. 5. It is recommended that training in node cutting methods be conducted by resource persons from Taipu nursery who have already exhibited expertise in this sector. 6. Species / quality certification for supply of quality planting material used for propagation and plantation needs to be ensured. Suitable expertise within West Bengal exists outside the Forest Department including at the Botanical Survey of India and Bose Institute. These avenues need to be explored to increase productivity of the bamboo plantations. 7. Additional pest control measures need to be undertaken for termite infestation to prevent damage to plantations. 8. Current Working Plans prescribe plantation of bamboo in Development Circle. However, it needs also be considered for Sal Working Circle as an associate of sal where suitable to increase the coverage of area under bamboo as per provisions of the NBM. Necessary modification of prescriptions require to be undertaken. 9. Working Plans should fix specific harvesting schedule for bamboo extraction given the large tracts of bamboo plantations being created under NBM. 10. Since bamboo is an NTFP and technically a grass, status of collection of bamboo in view of existing JFM rules and regulations assuring royaltyfree collection by FPC members may need examination.
