The present investigation was undertaken to characterize the floristic composition, structure, vegetation diversity and changes in physico-chemical properties of soil at different altitudinal zones of Shola forests in the Nilgiri hills of Western Ghat. The floristic composition revealed that the Shola forests of Brammagiri hills of Western Ghllt consist of 91 families belonging to 70 genera and 43 families. Vegetation structure showed that Cinnamomum perrottetii has highest density followed by Actinodaphne salicina and Microtrt.pis stocksii. However, highest basal area was for Ligusrtum perrottettii and Neolitzea zeylanica. In regenerating community, Actinodaphne salicina represents maximum regeneration followed by Bhesa indica. Plant diversity study indicated that Simpson's index was 0.94 and concentration of dominance was 0.06. Investigation on physico-chemical properties of soil revealed no remarkable variation in soil properties with increasing elevation.

A coppicing study done at College of Forestry, KeralaAgricultural University, Vellanikkars revealed that a,ll the four species selected viz., Macaranga peltata, Samania saman, Terminalia belerica, Albizia falcataria and four provenances of Dalbergia latifolia were having good coppicing power. Maximum number of coppices were produced by Terminalia belerica while provenances of Dalbergia latifolia produced sprouts of more length, girth and leaf production. In general, coppicing ability was found to be more when pruning was done at a height of 60cm.- Use of Municipal Garbage for the Production of Quality Swietenia macrophylla King (Mahogany) Seedlings

Domestic refuse and non-hazardous wastes such as commercial and institutional wastes are turning to become the major threats to the human health and environment. Municipal waste management is the most challenging issue since these wastes are dumped in open places and not being used or treated for any purpose. It has created a real threat not only to the living environment but also for the cultivation of crops as well as afforestation. The present investigation was conducted to study the influence of two weeks decayed or stored waste materials as component potting media on the growth and vigour of Swietenia macrophylla (mahogany) seedlings. The municipal waste, coir waste and tea wastes were mixed with sand and soil in different concentrations. At the end of the study, the growth and biomass production was higher in soil : partly decayed municipal waste in 1:1 (T2) and high quality seedlings were produce in control (soil, sand and cow dung in 1:1:1). Above ground and below ground biomass was maximum produced by soil : partly decayed municipal waste (T2) and control (T1) respectively. The physiological characters like number of leaves, specific leaf weight and chlorophyll content were highest in soil, the potting media of partly decomposed municipal waste : sand mixture (T5). Leaf weight and relative growth rate gave highest in soil : partly decayed tea waste : sand in 1:1:1 (T7). The present study revealed that potting media of partially decomposed municipal as well as tea waste in combination with soil and sand provided better performance in growth attributes. The present investigation reiterated that municipal or industrial waste will be a good alternative to the standard potting media which is widely used in the mass production of seedlings of mahogany in the nursery.Keywords

Kerala enacted the Kerala Forest (Vesting and Management o f Ecologically Fragile Lands) Act, 2003 to conserve ‘fragile ecosystems’ lying contiguous to reserve forests. As this Act led to several litigations and conflicts, the current concept of Ecologically Fragile Lands (EFL) was concept mapped among the different stakeholders, including ‘small and marginal’ farmers in the context of Wayanad district, Kerala. Several dimensions o f EFL, viz. ‘Ecological’, ‘Situational’, ‘Socioeconomic’, ‘Framework’ and ‘Better EFL’ were developed and debated to evolve a more acceptable EFL concept. The study also accentuates the relevance of public participation in conceiving socially inclusive forest laws and policies.Keywords
