Chromolaena odorata (Eupatorium odoratum), commonly known as Eupatorium, is an introduced weed which became a menace in plantations, forests, marginal lands and open areas in the Western Ghats region of Karnataka. The weed calls for effective control by applying suitable methods.

Orissa is one of the most backward states of India with 47 per cent of the population living below poverty line. Forests constitute 37 per cent of the state's geographical area and are the major sources of income for the poor, particularly tribals.

Forests provide a number of goods and services to the people. The dependence is very high especially amongst the tribals who live close to nature and collect food, fuelwood, timber, bamboos, medicinal plants and other non-wood products from the forests.

Lantana camara Linn. is a noxious weed posing a serious threat to the ecology. It demands concrete efforts for its management. L. camara was evaluated for its pulp and paper making properties. Data on chemical constituents, fibre dimensions, unbleached, bleached yield and physical strength properties of pulp sheets were obtained.

Of the diverse flora and fauna in an ecosystem, epiphytes in general and orchids in particular have a vital role to play in mutualism. By virtue of their sensitivity to the changes in the climate they provide a forewarning about the impending damages due to these changes and act as bioindicators. Epiphytes constitute ten per cent of the higher plants in tropical forest ecosystem.

Experiments were conducted to control Lantana camara in Shiwalik hills of Punjab through chemical treatment.

The present investigation deals with natural chemical reserves and physical characteristics of leaf litter of 35 dominant tree species of Nilgiri Biosphere Reserve and efficacious impact of leaf litter of a few selected species on physico-chemical properties of sodic soil.

The Niyamgiri hills in the South-Eastern parts of Orissa are a unique forest ecosystem harbouring rich floristic composition and vast natural resources.

The assessment of carbon storage potential has been difficult due to the lack of information on biomass compartmentation and carbon allocation in different species. For most of the species used for afforestation/reforestation, only the above ground biomass potentials are known but to have a picture of carbon storage potential species, the below ground biomass pattern are equally important.

Investigations were carried out in 26 sacred groves of the district of Bankura of West Bengal during 2006 to 2007. 114 plant species were recorded from those groves including 102 dicots and 12 monocots. The major tribal groups in those areas are Santals and Koramudis; others are Bedias and Mahalis. Main festival of Santals is 'Sarul' under the canopy of Shorea robusta.
