Abstract:
Today the world is on the brink of massive collapse of ecosystem and the species they contain due to deforestation fragmentation of habitats, insularisation due to developmental pressure and human population growth. Madhya Pradesh has been very rich in biodiversity since times immemorial. Achanakmar-Amarkantak Biosphere Reserve has a long tradition, respect, care and great concern for biodiversity and its conservation. As the tribal life is based on forest, hence these tribal people practice judicious use of the plant resources and conserve many plant species. The tribal of Achanakmar-Amarkantak Biosphere Reserve conserve 88 plant species. The principle behind this conservational atitude is based on their magico-religious faith, beliefs and their taboos and totems. Conclusively, as the tribal life is forests based hence, the tribal practice judicious use of the plant resources and conserve many plant species.
KEY WORDS: Conservation, Management, Biological diversity, Achanakmar-Amarkantak Biosphere Reserve.
INTRODUCTION:
Conservation of the biological diversity is one of the fore most issues in the present era. During the last 10 years, plans for biodiversity conservation have developed by WRI and the IUCN with support from World Bank and other institutions. Basically the conservation plan has holistic approach and encompasses whole spectrum of biota and activities ranging from ecosystem at macro level to DNA libraries at the molecular level. Conservation is the protection, preservation, management or restoration of natural resources. Through the conservation of biodiversity and the survival of many plant species and habitats which are threatened due to human activities can be ensured.
Today the world is on the brink of massive collapse of ecosystem and the species they contain due to deforestation fragmentation of habitats, insularisation due to developmental pressure and human population growth. Darwin published “Origin of species” in 1858 and today we are writing “The obituaries of species” in the form of Red Data Book. India is the second most populous country and therefore, any plan attending at conservation must consider socio-economic development as the mounting human pressure threatens the biotic resources of the country. Madhya Pradesh has been very rich in biodiversity since times immemorial. Achanakmar-Amarkantak Biosphere Reserve has a long tradition, respect, care and great concern for biodiversity and its conservation.
Green plants are all around us we are totally dependent on them for food; we cultivate them for our pleasure and we have used them in vast number of ways down the centuries to our advantages.Plants are our national heritage with global importance and India is endowed with a rich wealth of biodiversity. Madhya Pradesh is rich in plant resources used in various system of medicine as well as indigenous made of treatment.
The density of plants were gradually decline due to over harvesting and consequently poor regeneration in central India due to commercial demand and immense biotic pressure, most of the plants are in danger under wilderness. They also cautioned that if the present condition continues, these species will soon have completely vanished from the natural forests. The continuous exploitation of several medicinal plant species from the wild and substantial loss of their habitats during the past 15 years have resulted in the population decline of many high value medicinal plant species over the years.
Due to selective and excessive exploitation of few picked up species without proper management practices for their regeneration and due to simultaneous destruction of certain natural ecosystems, nearly a total extinction of a number of species results. Once such extinction of a particular species occurs, that gone, combination is lost forever. Concomitantly the disappearing species causes extinction of other dependent species of higher animals. Conclusively, the conservation of these plants species and resources is of almost important, not only to manage and conserve the biotic wealth but also restore the degraded ecosystem.
Excellent work has been done on composition, structure and floral diversity of forest communities of Achanakmar–Amarkantak Biosphere Reserve and its conservation implication are Saxena(1972),Tiwari et al.(1995), Singh et al.(2005),Bondyaet al.(2009), Agrawal et al. (2010),Singh et al. (2010),Kapale(2012),Ahirwarand Sandya(2015).
Consequently, useful information about conservation of biodiversity have been contributed by Alcorn(1996), Arora (1996), Balasubhrmanianand Prasad (1996), Kaul (1996), Prasadand Balasubramanian (1996),Ramkrishanaet al.(1981), Rana et al.(1996), Ravishankar(1996),Samantet al.(1996): Sinha (1996), Vartak(1996), Vedet al.(2001), Dubey et al. (2007), Mishra (2015,2018).
For the preservation of the endangered species the only measure suggested is the strict protection against poaching of plant resource. Today, a network in India of 668 protected Areas has been established, comprising 102 national parks and 515 wildlife sanctuaries, 47 conservation Reserves and 4 community Reserves covering an area about1, 61,22,157 sq.kms., constituting 4.90% of the total geographic area of the country, one fifth of the forest area. The protected area included 48 tiger reserve as well as 18 biosphere reserve. Achanakmar-Amarkantak Biosphere Reserve is one of the important conservation of vegetational flora. The tribal of Biosphere Reserve protect some plants due to their duties and they also forced by the Govt. management to protect plants.
Role of tribal in plant conservation:
Analysis of the conservational values of a region by the tribal is one of the important aspects of ethnobotany. In respect of tribal population, Madhya Pradesh is the largest and highly tribal populated state of country. There are 46 recognized Scheduled tribes comprising 161 tribal sub groups in the state. Out of 51 districts of the state 32 district have tribal populations.About 21.1% of total population of tribes of the country lives here.About 95% of the total population of Dindori district is living in the rural area while roughly 5% are urbanized. In Dindori 65.33% of the area is tribal.Anuppur district have a population of 667,155 according to Census(2001).309, 624 people are from Scheduled Tribes and 48,376 are Scheduled Caste. According to report by the Govt. of India at least 34% are Scheduled Tribe 12% is Scheduled Caste. The Gond, Baiga, Panika,Bharia, Kanwar, Pao, Kol, Pradhan and Agariya are the largest tribal of Achanakmar- Amarkantak Biosphere Reserve.
The forest plays a vital role in the economy as well as daily needs of the tribal. The tribal people acquired knowledge of wild plants mostly on a trial and error basis. Tribal do not familiar with the thousands of plant species in their ecosystem, but also understand the ecological inter-relations of the various components of their resources base better than most foresters, Biologist, Ecologist and Agronomists.
The tribal societies and cultures are themselves disappearing and with them go their traditional plant lore, with the changing ecosystem the tribal are in a state of total disintegration. The habitat and the environment where the tribal experienced and learnt useful lore are also fast disappearing on account deforestation and intensive farming much of our present knowledge on plant resources has its origin in primitive cultures. The rich plant lore has been passing on by word of mouth and by tradition from generation in different parts of the world. There are still 72 primitive tribal groups in the India whose life style revolves round the forest. Their knowledge of the use of plants is often kept secret and passed on by verbal tradition only.
Tribal use a large number of plant species in their daily life as food, fiber, medicine, timber, fuel and dyes etc. for their subsistence. These sources are prone to become extinct if used continuously and non-judiciously. The so called increasing urbanization is also adversely affective these resources and thus they are becoming extinct. There is a burning need for the conservation of these plant resources.
In order to conservation of ethnobotanical resources three aspects need to be considered on priority, namely:
· Fragile nature of the habitat,
· Encasing regenerative ratios,
· Finding evolutionary tendencies adoptive to anthropogenic stresses.
Due to many reasons the habitat of several resources may get drastically changes or destroyed, thus leading to the loss of their sources itself. Sometime changing the habitat proves useful in regenerating the lost resources, but in majority of the cases it is not so as changing the habitat cause change in the ecotypes within a species and an ecotype differentiation many times proves unproductive. To prevent the damaging habitat, fast regenerative capacity is needed but thus cannot be obtained easily, thus the need to indulge into the doctrine of ‘Development through Conservation’ becomes pertinent. It will guide the developmental programmed of the primitive tribes of the region without causing any harm to the resourceful habitat leading to conservation.
The tribal are unaware of the modern views based on advance science for the preservation of forests, but depending upon their age long experiences they are fully aware of the importance of forest cover. The entire tribal are certainly maintain a patch of forest as sacred forest as their beliefs and sentiments are deeply attached to these forests and hence they avoid and do not cut or destroy these forests. This is the main reason for still extensive forest cover of the Biosphere Reserve as it has been saved from “Bewar” cultivation practiced extensively here.
Sometimes tribal protect even the individual plant species worked by them. Even some groups are named after the name of the plant. Tribal not only worship the plants of their groups and women of these groups even cover their faces by veils when they pass close from near those plant. They never harm such these plant species and these conservational attitudes are based on their magico-religious faith, beliefs and also on their social taboos. The information regarding the plants conserved by the tribal of region and justification.
The tribal of Achanakmar-Amarkantak Biosphere Reserve conserve the plant species. These conserved plant species are shown in table:

Due to the reason specified against each plant species mentioned on the Table. Plants are not exploited commercially or even at the community level by the tribal and hence, are collectively conserved with sacred touch. As the tribal life is based on forest, hence these tribal people practice judicious use of the plant resources and conserve many plant species. The tribal of biosphere reserve conserve 88 plant species.
The principle behind this conservational altitude is based on their magico-religious faith, beliefs and their taboos and totems.Out of which some of some plants likeAchyranthes aspera, Adina cordifolia, Anthocephaluscadamba,Boswellia serrata, Dendrocalamusstrictus, Ficusreligiosa,Ocimum sanctum andFicusbengalensisetc. are regarded as sacred plants in weddings, festivals and worshipped.On the other hand the parts of Cynodondectylon, Aegle marmelos, Buchananialanzan,Calotropis procera, Curcuma longa, Datura metal, Hibiscus rosa-sinensis,Mangiferaindica, Semecarpusanacardium, Sesamum indicum, Shorearobusta, Solanum surratenseand Thevetia peruviana etc. are used during worship in the form of twigs, leaves, flowers,fruits, seeds and wood.Oryza rufipogon,Musa paradisiaca, Madhucaindica, Datura alba etc. plants are used as praised during worship. In addition to above certain plants which have no substitute for medicinal, dye, food, fish poison, and agriculture implements plants are also properly conserved.
Many plant species are utilized by tribal in their different magico – religious ways, without affecting the conservational aspects as harvesting of root or whole plant will be descriptive in nature while the use of fruits, Bark and seed does not do so. Harvesting of leaves too may not be dangerous but the method, time and amount of leaves harvested has to be kept in mind. Thus, it can be concluded that recording traditional methods of harvesting and identifying resources is important for understanding the regeneration capacity and perpetuation possibilities of the plant species.Conclusively, as the tribal life is forests based hence, the tribal practice judicious use of the plant resources and conserve many plant species.
Conservational strategies:
Conservation biology is the science of the preservation of species and ecosystem, which includes the understanding of ecological principals of conservation, insularisation due to fragmentation of population and in situ and ex situ strategies of conservation. The World Commission on Environment and Development (WCED) constituted by the General congress of United Nations published its report in 1987, which provide a major boost and endorsement to the need for conserving worlds rich biodiversity, particularly that of the tropical regions.
Inspite of conflicting views among nations, abroad consensus was reached and 170 countries signed the Biodiversity Convention. One of the prerequisite tasks as expressed by the article 7 of the convention is theidentification and monitoring the components of the biological diversity. Article 12 calls for research and training and suggest programmes for identifications, conservations and sustainable uses of biodiversity. In context of country conservation of threatened species is essential not only to maintain the ecosystem but also to ensure the sustainable use of the species.
Each vegetation has particular forms of species and each form is specially adapted to a particular site where it grows. Differences between them can be identified and used for better management. Achanakmar-Amarkantak Biosphere Reserve is a tremendous storehouse of potential resources not only for taxonomical and ecological researches but also as a source of yet less known medicinal plants.
Some conservational strategies followed by the inhabitants of the Achanakmar-Amarkantak Biosphere Reserve are as below:
1. In-situ conservation:
Biodiversity at genetic, species and ecosystem level can be conserved on a long-term basis only in the nature. Unless plant population conserved in the wild area. That is natural habitats, in variable breeding population; they run the risk of extinction. In situ conservation, the conservation of species in their natural habitats, is considered the most appropriate way of conserving biodiversity.
Plant populations have large and often disjunctive area of distribution while some plant species are confined to a few pockets. Conservation of these plant species being done by the forest department with the participation of local people by raising stone wall fencing. By this process the naturally generated plant species would be increased. However, for a long term conservation and management of plants species in-situ network need to be integrated into regular forestry and wild life management. Essential training should be given to the local people to involve them in protection and management of the plant diversity. Around 4% methods of the total geographical area of the country is used for in situ conservation. Biosphere Reserves, National parks, Botanical gardens and Wild life sanctuaries are the presently used for in situ conservation.
2. Ex-situ conservation:
Ex- situ conservation is an essential step towards the protection of Plant diversity. Ex -situ conservation is supplementary to in-situ work, but can also play a vital role. This is where a species is conserved away from its natural habitats. This involves conservation of genetic resources as well as wild and cultivated species. The tribal and rural people adopted following ways for the conservation of valuable plant species. Many of the species which require ex situ conservation are those suffering extreme threats in the wild. Ex situ methods focus on species conservation in nurseries, home garden, gene bank etc.
(a) Home Garden:
Gardens are more favorable for ex-situ conservation of valuable or medicinal plant species. Though, the several botanical garden in India. The natural genetic wealth including wild relatives of cultivated plant species, rare, endangered and threatened plant species are not given priority over ornamental plants and other exotic plants in these gardens. These types of gardens are not available in the study area. However, the inhabitants raised their some own home garden where they grow and protect some valuable plants, which is used in routine. In addition to spice and vegetable plants, it is a sincere step towards the conservation of plant diversity by the rural people.
(b) Nurseries:
The most vitalrole in order to make sureinstant availability of plant species and planting materials to various uses groups like farmers, plant breeders, industry and to conservation organization is to promote and develop the network of plant species. Nurseries which will multiply all the regional specific plants that are used in current practice be source of plant materials.
The forest department, agricultural extension agencies, non government organization and some private enterprises are playing vital role in establishing these nurseries.
