In the present study various phytosociological attributes like frequency, density and abundence of woody vegetation were analysed along the disturbance gradient in tropical dry deciduous forest of Hastinapur region of North west Uttar Pradesh, India. Three sites were analysed for floristic composition, distribution pattern, species diversity and dominance (i.e. Hillock,Block-1 and Block-2)Hillock was highly disturbed, while Block-1 and Block-2 were moderately and least disturbed sites respectively. Maximum number of tree, seedlings and saplings were recorded for Block-2 and minimum for Hillock. Number of shrub species was maximum on Hillockbecause of open forest canopy due to disturbances, which provide favourable conditions for growth of shrubs and other weeds. Most of species except shrubs were regular followed by random in distribution pattern. The value of CD and H’for trees 0.01 on Block-1 to 0.035 on Hillock and 0.00 on Block-2 to 0.014 on Hillock respectively. These low values clearly indicate aridity of the area and habitat destruction. Phytosociological study of this area indicates that there is an urgent requirement of conservation practices

Disturbed Stand

Different parameters of Soil and vegetation analysis were carried out in Tropical dry deciduous forest of Hastinapur region of Uttar Pradesh. Vegetation of present study sites showed effects of various anthropogenic disturbances. The highly disturbed stand I showed low tree density while less disturbed stand III showed high tree density and good regeneration pattern. D-D curve were also drawn on the basis of the IVI of different species. Population structure of different tree species was drawn to understand the regeneration pattern. The most characteristic feature of the forest is dominance of xerophytic species and open forest canopy due to disturbances. Overgrazing and other biotic factors are making the area poor both in nutrient and top soil, which will eventually result in desertification of the Hastinapur in long run.

Declining Species

The dry tropical ecosystems are among the world's most threatened, and the dry deciduous forest of northern India is being progressively converted to scrub, savannah and grasslands through industrialization, agriculture, fuelwood collection, lopping of trees for fodder and severe grazing/browsing. This habitat destruction threatens the survival of many species. This study examined the demographic instability of tree species in 3-ha permanent plots: at five sites differing in the degree of disturbance. Based on the proportion of seedlings of a species in its total population (seedling + sapling + adults), about 52% of the total 65 species exhibited local demographic instability, and at one or more sites a single individual represented 10 species. The increase in the proportion of declining species with increase in disturbance intensity indicated that local anthropogenic pressure is responsible for the depletion. Apart from stronger protection measures, it is necessary to encourage fuelwood plantations, develop village pastures and reduce livestock numbers.

A New Species

A new species of Lophopogon (Poaceae), L. prasannae is described from dry deciduous forest of Ananthapuramu district, Andhra Pradesh, India. This new species shows morphological similarities with L. tridentatus and L. kingii but differs in certain characters, which are discussed below. A detailed description, photographs and taxonomic key are provided for easy identification of the species.

Dry Deciduous Forest

The specific gravity of 220 woody species, half of them from a tropical rainforest, half from a tropical deciduous forest was measured. The two groups were compared using a Student t-test. The results show highly significant differences in specific gravity between the species from the two areas: woods from the dry deciduous forest tend to be much heavier than those from the rainforest.
