It involves clearing a patch of forest land‚ but retaining useful trees and plant varieties‚ cultivating it for two to three years and then abandoning it for 10-20 years to allow the natural forest to grow back and the soil to regain its fertility. The cycle of cultivation‚ leaving it fallow and coming back to it for cultivation‚ is called the Jhum cycle. Traditionally‚ a village community owns/controls the forest land and decides on such rotational cultivation pattern. Thus the community cultivates

field and the deciduous forest are not too different from each other. However‚ the Plant Respiration (RP) in the forest is almost double that in the alfalfa field. What factors (physical‚ chemical‚ or biological) do you think might explain this difference? The difference would have to be the biological and physical factors. The reason for this is the cycle in deciduous forest goes through. Tree insects and diseases are most common in older forests. They help to rejuvenate the forest by decomposing

It shares its east with Deccan plateau and west with Banasura hills-part of Western Ghats. Wayanad is a precious land with huge diversity in butterfly life. I have participated in last two butterfly survey camps organized by the forest department of Kerala‚ in Wayanad wildlife sanctuary and Brahmagiri hills. The richness and diversity of butterfly species revealed that there must be some more varieties of butterflies present. Butterflies are organisms with a short

Hardwood contrasts with softwood. Hardwoods are not necessarily harder than softwoods. In both groups there is an enormous variation in actual wood hardness‚ with the range in density in hardwoods completely including that of softwoods;
