Abstract

With a view to study a possible correlation between occurrence and extent of fire and weather conditions, a case study was taken up in the forests or West Dehra Dun Forest Divison. Occurrence and extent of fire over a period of a decade (1968-1977) and weather conditions obtaining at the time of occurrence of forest fires, were critically examined. Mean temperature, average maximum temperature, precipitation, relative humidity, wind velocity etc. were the important weather parameters considered for analysis. The study indicates that a certain corelationship does exist between weather conditions and occurrance of fires. Based on the empirical knowledge, a Fire Danger Rating Index for the study area has been evolved.

Abstract

Reboisment of saline, alkali soils with useful tree species is engaging attention or investigators. Salinity tolerance testing of indigenous and exotic tree species is considered as a tool for the quick selection of suitable species. Australia, which has Pre-deminantly semi-arid-arid climate and has extensive saline-alkaline soils, is a potential source of suitable tree species. A list of promising Australian species for Northern India is provided. Quick appraisal through salinity tolerance at germinstion stage of Casuarina cristata, C. cunninghamiana, C. obesa and Melaleuca glomerata is described Acacia nilotied ssp indica, the indigenous species Which is highly recommended for salin areas, is evaluated for comparison. The trials indicate that Casuarina obesa and Casuarina cristata, are the most promising tree species Casuarina cunninghamiana and Melaleuca glomerata have limited scope. Further studies are recommended.

Abstract

During 1981 fire season field demonstrations-cum-studies on efficiency, suitability and economics of the Fire Rake ond Blowers were conducted in East and West Debra Dun Forest Divisions. It is found that the blower is more efficient and faster as compared to rake, but operation of blower being costlier than the rake blower be preferred in case of emergency only and not as a general practice. Maintenance of fire breaks by cultivation of evergreen shrubs may prove to be more economical and effective in comparison to mechanical process.
