Abstract

A survey was conducted in 150 agricultural fields where agroforestry has been followed. Five main multiple plantation patterns of agroforestry systems were followed which includes 2 to 6 plant species. It made 30 different crop geometries (CGs). In each pattern, there were several types of CGs mainly categorized on the basis of number of plant species grown in the central part of the agricultural field (1, 2, 3 or 4 species). All these types were usually followed by the farmers as per the local need, market demand of their product and financial gain to the farmers. The C : B ratio of various multiple plantation patterns has proved this fact.

Abstract

Occurrcnce of frequent fire is one of the reasons for degradation of forests in the country/ elsewhere in the world. The forest fires affect (a) standing vegetation, (b) soil, (c) productive capacity of the forest, (d) productive value of the forest, (e) wildlife and (f) recreational. Or scenic values. An attempt has been made to map the fire-prone areas of a part of Junagadh District of Gujarat. IRSIB, LISS-II data were visually classified to ascertain the vegetation status of the study area. The roadnetwork and the huts/settlements were mapped through the Survey ofIndia (SoI) topographical map. Finally, to begin with, these three parameters out of many, which may have direct/indirect influence over the occurrence of fire, were integrated using Geographic Information System (GIS) approach resulting in a 'fire-prone' map of the area.

Abstract

Sardar Sarovar Project (SSP) is multistate multipurpose river valley which is expected to benefit and aid in development of four states namely Gujarat, Madhya Pradesh, Maharashtra and Rajasthan. The catchment area of Narmada river above Sardar Sarovar Dam, is 88.000 km² of which 1676 km² area is part of Maharashtra State. The area is predominantly forested and tribal in nature and social and economic life of the people is totally dependent on forest for food, fuel, fodder, timber and medicines. This needs for up-to-date and reliable information on current status of land utilization for important planning processes such as catchment area treatment (CAT). At the instance of Maharashtra Forest Department a detailed microlevel catchment area treatment package was evolved using remotely sensed satellite data (IRS-LISS II and SPOT) and the recommendation for five categories of CAT has been made to preserve forest and biodiversity in the catchment area along with development of tribal community by way of massive afforestation programme coupled with soil and water conservation. Five years phasing of CAT plan with annual target of 20% area under various treatments have been recommended. The total cost of the CAT plan has been worked out around 2801.40 lakhs with an employment generation of 64.39 lakhs man days. Based on this CAT plan using remotely sensed data the implementation of the CAT has been started from Oct, 1993 with an opening of four new Watershed Management Division by the Maharashtra Forest Department.

Abstract

Two abnormal seedlings, One of Pinus caribaea Morelet var hondurensis proveanance 43/71 and the Other of P. oocarpa Sahiede Proverance 9/70 were obaerved during a study of seed and sedling characteristics of various provenances or these species in relation to their geographical parameters Aboormalities Were similar in both the seedlings and several possible hypotbetical explanations Have been given in this note for these abnormalities.

Abstract

Observations on the relative growth performance of seedlings over a 100 day period suggested strong relationships of seed weight with several growth factors in the early development of some selected provenances of Pinus oocarpa Schiede. Significant degrees of correlations of seed weight with height, dry weight, ischolar_main collar diameter and ischolar_main length of the seedling were apparent. Presumably seed weight can be used as a parameter for predicting seedling growth rates in nursery phase of development and for a short period in field establishment too. Relationships were found to exist in the seeds of different geographical areas.

Abstract

The present deals with the study of aerial biomass of 3 dominant forest tree species of Sagar i.e. Anogeissus latifolia, Tectona grandis and Terminalia tomentosa of about 20 years in age. In this investigation it bas been observed that the total biomass of all the plant parts in the above species is approximately equal (80-83 kg). On the whole it has been estimated that about 55% of the aerial biomass is removed from the forest ecosystem as timber, about 25% is used as fuel or coal while the remaining 20% of the crop which is of no use for the forest contractors is left inside the forests. This coasists of twigs and leaves and gets decomposed subsequently. 8% of the biomass falls in the from of leaf litter every year if such a forest is left uncut. On an unit volume basis the weights of wood and bark of Terminalia are the largest. There is a positive correlation between the leaf dry weight and its area while the percentage of bark and the girth of trunk show a negative correlation.
