The present paper deals with the detailed study of a degraded miscellaneous forest of Manikpur village forest committee of Mandla district of Madhya Pradesh, India by examining various socio-economic needs of people, documentation of plant diversity of the area in both qualitative and quantitative terms, regeneration behavior of various timber and non timber species, phyto-sociological structure of ground vegetation including herbs, shrubs and grasses, biomass production, fertility status of soil, identification of different land use zones for obtaining optimum productivity through their effective utilization etc. Innovative site specific eco-silvicultural options encompassing social, economic, cultural, spiritual, ecological and institutional aspects of management, were prescribed to ensure multi-product flow of forest resources, optimum utilization of various land use zones through collaborative efforts of Ministry of Environment and Forests (MOEF) and Ministry of Agriculture, ecological balance or homeostasis of ecosystem through maintaining ecological processes like nutrient cycling and energy flow, and ultimately the prosperity of forest dependent communities.

Buchanania lanzan Spreng (common name - Char, Chironji) belonging to family Anacardiaceae. This plant was first described by Francis Hamilton in 1798. It is a non wood tree species found in deciduous forests throughout the greater part of India and generally attaining a height up to 18m and girth 1.5m. In Madhya Pradesh, it is a common associate of teak, sal and mixed forests. It is used for environmental conservation and in 'agroforestry system'. It is used as a fuel, fodder specially buffaloes alternative host Kusmi lac insect, and its oil for cosmetic items and soaps. Its oil is also used by tribal as edible oil. Seeds/kernel of Buchanania lanzan are nutritional, palatable and used as a substitute of almonds in confectionery. They yield a fatty oil known as Chironji oil and substitute for olive and almond oils in both confectionery and indigenous medicine used for glandular swellings of the neck (CSIR, 1986). Fruits are laxative and used to relieve thirst burning of body and fever. Kernels of fruits are used as ointment in skin diseases (Das and Agrawal, 1991). Tree of Buchanania lanzan flowers from January to March and fruits ripen in the month of April-June (Troup, 1986). Fruits become red after ripening. The fruit collection take place from April to June. Early harvesting results into low fruit/ seed quality and poor germination potential. In most parts of M. P., fruits of Buchanania lanzan are harvested before ripening. With the result, it fetches low price in the market because of small seed size and low seed quality. In natural forests, its regeneration is vary scanty due to unscientific and pre-mature harvesting of its seeds and site degradation on account of growing biotic pressure. Keeping above in views, there is a need to find out the best harvesting period of Chironji fruit/seed with special reference to seed size, seed weight, biochemistry and germination potential of seed. The present communication deals with morphological, physiological and biochemical study of Buchanania lanzan seed harvested at 7 days interval during its various developing stages from April to May. The fruits were collected from forests of Kundam range in Jabalpur forest division for the present study. The best results in terms of seed size, seed weight, germination percent, oil content etc, were obtained in the fruits harvested in the 2nd week of May. Source

Studies were undertaken to assess the extent of genetic divergence among the progenies of eighty-eight plus trees selected from the entire distributional range of Pinus wallichiana in Kashmir Himalaya at the age of one year to identify the promising selections for use in future improvement programmes. The study resolved the eighty eight plus tree progenies into ten clusters using Mahalanobis D2 statistics. Cluster IV was largest with 21 genotypes (plus tree progenies). The inter-cluster distance was highest (9.901) between cluster IX and VII. Clusters mean indicated that cluster VIII was the best in respect of seedling height (12.82 cm), collar diameter (9.62 mm), needle length (5.76 cm), needle diameter (0.38 mm) and number of needles per seedling (17.44). The superiority of cluster VIII allows use of Arthnari and Seer plus tree progenies for operational plantation purposes. © International Society for Tropical Ecology. Source

Strychnos nux-vomica belonging to family Loganiaceae. Carbohydrate, protein, oil, steroid, alkaloid, resin, strychnine and brucine were detected in phytochemical screening. It is anticipated that lipid peroxidation may provide scientific rationale for the use of S. nux-vomica as an antidiabetic plant. There is a need to develop bio-technological approach for raising nursery plants of S. nux-vomica as per International Union for Conservation of Nature and Natural Resources (IUCN) criteria. Different concentration of growth hormones to break seed dormancy, four pre treatments, different size of polythene bags, root trainer, and impact of potting mixture on the growth were adopted to determine the best treatments. The results indicated that the seed dormancy was broken when seeds were treated with 40 ppm concentration of GA3 or 100 ppm concentration of IBA hormones and soaking with warm water, the best size of polythene bag was used as medium size of polythene (25x11 cm), the best size of root trainer was used as medium cup root trainer (187 cm3), and the best potting mixture was found to be farm yard manure (FYM) with soil and sand in ratio of 1:1:1. Statistical analysis was also adopted to determine of significance levels. © 2015 SERSC. Source

Shorea robusta is threatened these days due to sal borer attack, sal mortality, poor regeneration potential, edapho-climatic changes and various biotic interferences. No systematic attempts were made to understand dynamism of its natural regeneration and to suggest management inputs to encourage its regeneration. The present study deals with the natural regeneration of sal and its associates in Satpura Tiger Reserve, India. The results indicated that the average number of regeneration of sal seedlings per hectare worked out to be 6372 ha-1, which are quite adequate. The distribution pattern of individuals of Shorea robusta trees in different girth classes was also seemed to be uninterrupted in most of the stands studied. This trend of uninterrupted distribution of sal in different growth phases with plenty of established regeneration is the healthy sign of establishment and growth of Shorea robusta crop in the past in this area. Other associates showed different growth patterns. © 2013 SERSC. Source
