Ethnobotanical studies of plants of Charkotli Hills, Batkhela District, Malakand, Pakistan

A survey was conducted with the aim to document the indigenous information of Charkotli Hills, Batkhela District, Malakand, Pakistan. The area has rich vegetation and a high potential for ethnobotanical utilization. Information was collected on various traditional uses of 100 plants distributed over 49 families, of which 43 families were of dicot, 2 of monocot, 2 of pteridophyta, and 1 of gymnosperms. Most plants have more than one local use. Sixty-six plants were found to be medicinal species, 21 fruit and edible seed species, 11 furniture species, 18 fodder or forage species, 12 vegetable species, 12 fuel species, 11 thatching and building species, 5 hedge or fencing species, 5 timber wood species, 5 poisonous plants, 3 species used in ketchup, 2 fixed oil yielding species, 2 miswak species, 2 species for making sticks for cattle and defense purposes, 2 species cultivated for ornamental purposes, 2 species used as mehindi by girls, 1 irritant species, 1 species for the making of Salai (a little stick for applying ‘surma’ to the eyes), 1 species for tanning, 1 species used as refresher in milk pots, 1 species giving gum used as chewing gum, and 1 species used as insect repellent. The area is under heavy pressure of deforestation and overgrazing, which have reduced the regeneration of woody plants. Proper ecological management is required to protect the wildlife and ethnobotanical resources for the coming generations.

Avian Fauna of Khajjiar Lake, District Chamba, Himachal Pradesh, India

Avifauna of Khajjiar lake revealed the presence of 77 species of birds belonging to 62 genera, 12 orders and 31 families. In this area Muscicapidae is the most represented family with 22 species belonging to 15 genera followed by Accipitridae and Corvidae (six species each), Paridae, Phasianidae, Columbidae and Picidae (three species each). 20 species of birds were local and the rest 57 seasonal-local and long range migrants Of the 57 species, 35 were seasonal-local migrants, four were winter visitors and ten were summer visitors. Moreover, Khajjiar lake supported eight such species which showed winter and summer influx. Of these, six showed summer influx, whereas, winter influx was shown by two species only. Data on relative abundance showed that 25 species of birds were very common, 30 common, 21 uncommon and one rarely seen in the area.     

Phenological complementarity, species diversity, and ecosystem function

Increasing species diversity frequently enhances ecosystem function. Phenological complementarity, the asynchrony of species resource use and growth, may explain how species diversity influences ecosystem function but remains largely untested. We used an early successional plant community containing species with a variety of phenologies to test whether increasing species diversity enhances ecosystem function by increasing phenological complementarity. Over a two-year period, we increased environmental heterogeneity within an abandoned field with variation in disturbance, soil nutrients, water, light availability, and disturbance in 160 permanent plots, and measured percent cover of each plant species three times in each growing season. We did not manipulate species composition directly, and thus diversity and complementarity in each plot were the result of pre-existing conditions and responses of individuals to experimental treatments. Species diversity was measured in two ways, as the total number of species per plot and as the evenness of species abundances. Phenological complementarity was measured as the negative logarithm of the variance ratio. We tested whether the number of plant species per plot, species evenness, and their phenological complementarity in the first year predicted total annual cover in the second year. Total annual cover increased only moderately with number of species and evenness, consistent with studies that randomize species composition among replicate plots. Any effect that species number or evenness had on total annual cover, however, was not due to phenological complementarity. Rather, diversity was unrelated to phenological complementarity. These results indicate that naturally occurring variation in species diversity had little effect on whether phenological complementarity can enhance ecosystem function.
