SCOPE OF WORK: To conduct Biodiversity Research on the topic: “A Floristic and Associated Avian faunal Survey of the Forest areas of South West and North Bengal to monitor the changes in the population to initiate suitable conservation measures” by undertaking the following: 1. Identifying and demarcating representative monitoring plots through GPS 2. Preparing an inventory of trees, shrubs and herbs and associated bird species for each of the ‘monitoring plots’ for long term monitoring. 3. Elucidating various Indices from the inventory of the indigenous vegetation and bird species collected through the survey. 4. To compare this baseline/benchmark data with the available information to decipher the extent of changes taking place viz a vis the past. The terms of reference (ToR) is provided in Annexure 1A and the bill of quantities (BOQ) in Annexure 1B. Its implementation is coordinated by the Office of the Conservator of Forests, Research Circle and the Principal Chief Conservator of Forests, RMD through the following Divisional Management Units: a. DMU, Silviculture (South) at Medinipur, b. DMU, Silviculture(North) Siliguri and c. DMU, Silviculture(Hills) at Darjeeling. The background, objective, duration, tasks to be achieved, personnel requirement, expected outputs etc. are described in the Terms of Reference (Annexure 1A). 3. COVERAGE OF STUDY : Forests are among the most important repositories of terrestrial biological diversity which indicates the resilience of forest ecosystems to various pressures. Changes in climate affect the distribution of plant species and result in changes in forest composition. Changes in species composition may therefore affect several ecosystem properties. There is a strong connection between vegetation of an area and its avifauna. The indigenous species play a vital role in the ecosystem because they have evolved to be in this specific ecosystem and have a well-established role in the food web and the recycling of materials. Reduction in populations of even common indigenous species reduces overall genetic diversity of ecosystems and the ability of ecosystems and functional landscapes to adapt to future change It has been observed that some of the indigenous forest plant and bird species show gradual decline in population, both in southern and northern parts of West Bengal due to possible climate change, anthropogenic activities and other factors like pressure caused by invasive alien species, diseases etc. However, due to absence of any scientific study, it is difficult to address this issue or to quantify and enlist those declining species, though it is obvious that some level of degradation and population decline had already taken place. Hence, there is necessity to undertake a floristic and avian survey in representative forest areas Hence this study is proposed to prepare an inventory of trees, shrubs and herbaceous vegetation and associated bird species in the established ‘sample monitoring plots’ of South West Bengal, North Bengal Plains and North Bengal Hills for long term monitoring. 3.1. Selection of Permanent Sample Monitoring plots: It is intended to identify 38 Plots have been selected from representative forest areas of South West Bengal, North Bengal Plains and North Bengal Hills which are as follows.

It is well known fact that lianas and miscellaneous trees vanishes first in the case of biotic disturbances of climate change related impacts. Vegetation tends to shift to uphill due to climate change related effects. Hence analysis will be done on the relative abundance of new recruits of the species in the sample plots viz-a-vis the previous records. Lack of regeneration of trees can be attributed to increased biotic disturbances such as grazing, climate change related effects or edaphic characters prevailing in the area. Sampling for quantitative analysis will be done by taking five subplots of size, one hectare (100m×100m) quadrats in each plot of ten hectare (1000m×100m) size. The plot area (1000m×100m) will be ‘virtually’ demarcated with GPS. However, it should be noted that in hilly terrain it will be difficult to take plots of size 10 ha and therefore, the survey will be conducted in five subplots of 1 hectare each which may or may not fall within a single stretch of ten hectare. As for the shrub and herbs species, we use the standard ecological principles by way of adopting nestled plotsof size 50m x 50 m for shrubs and 10m x10 m for herbs. 3.2. Analysis of Data: Compilation of data for each tour and identification of species may be done simultaneously along with the field tours. An interim report shall be presented and based on the suggestions by the evaluating committee, additional tours (if any) may be undertaken for data clarification if required, preparation of maps, statistical analysis etc. Preparation of final report should be done during last three months. Following analysis may be done: 1. Species of vegetation listing location wise habit wise 2. Species of birds encountered location wise and habitat wise 3. Abundance, 4. Frequency & Relative Frequency, 5. Density & Relative Density, 6. Importance Value 7. Biodiversity Indices such as Simpson Index, Shannon-Weiner Index, Species richness, Species evenness, β -diversity indices( Sorrenson’s, Whittaker’s, Jacard’s etc). 4.
