Biological Spectrum with some other ecological attributes of the flora and vegetation of Shamlaji Forest, Gujarat, India.
Based on the current available information on the flora and vegetation of the Shamlaji Forest, spectra on life form and some other ecological attributes were analyzed and reviewed in different sub-ecosystem of the investigated area. The floristic list consists of 346 species belonging to 85 families of 74dicotyledons and 11 monocotyledons. Fabaceae and Asteraceae were dominating family in the study area. According to the Raunkiaerian life form therophytes (49.42%) followed by phenerophytes (42.77%) were dominant in the area. Contribution of Cryptpphytes(3.47%), Hemicryptpphytes(0.87%) and Chaemophyts(3.47%) is very less in the establishment of vegetation structure in the area. Deciduous vegetation is characterized by the largest percentage of therophytes and it falls under the category of therophytic type of phytoclimate. In this region, the vegetation expression was predominantly deciduous, although the tree flora has few elements of evergreen species. Physical climate of the area is arid and dry with three main seasons, monsoon, winter and summer. On average there are 40 rainy days in a year .Average rainfall is 760mm(10years) with a wide range of variation year to year. Temperature varies as per the season and the seasonal variation is very wide .Humidity is generally high during monsoon, otherwise dryness prevails. Soil in General observed sandy with varying proportion of loam and redish brown to grayish brown in colour. The dominance of phanerophytes appears to be due to sufficient rainfall, high temperature and low biotic pressure. However, the population of therophytic species is increasing in highly grazed and eroded areas.Keywords: Shamlaji Forest, Biological Spectrum, Phytoclimate
