The graminaceous flora of Jabalpur district is represented by 121 species belonging to 67 genera. Among them, occurrence of Arthraxon quartinianus (A.Rich.) Nash, Elytrophorus spicatus (Willd.) A.Camus, Eulaliopsis binata (Retz.) Hubb., Heteropogon triticeus (R.Br.) Stapf ex Craib, Microchloa indica (L.f.) P.Beauv., Oropetium thomaeum (L.f.) Trin., Perotis indica (L.) Kuntze, Tragus roxburghii Panigrahi, is rare. The study revealed that various biotic and edaphic factors play an important role in determining the composition of grasses and modifying their sequence of appearance. Most of the grasslands were subjected to constant pressure of grazing and burning, and therefore did not reach the climax form in response to climate. However, in certain protected pockets, they developed into main type- Sehima- Dichanthium, while in the disturbed areas they were replaced by various subtypes like Sehima-Dichanthium, Chrysopogon-Bothriochloa and Aristida-Eragrostis subtypes, depending on the degree of disturbance. Grasses have major ecological role in reclamation of an area, owing to their fast regenerating capacity, tolerance to drought and arid conditions.Keywords

Indian Forester, Vol 139, No 6 (2013), Pagination: 530-537Abstract
Using the stochastic production frontier approach, the technical efficiency of splint and veneer industry of Kerala was analysed. Ailanthus triphysa, Bombax ceiba and Melicope lunu-ankenda (Gaertn.) are still the main raw material species. But the demand of rubber wood as an alternate raw material is now rising. The mean technical efficiency (TE) of this sector was only 0.6. This paper discusses the social and other industrial reasons for the low efficiency in this sector. A migrant, unskilled workforce is possibly bringing down the efficiency. Coupled with this, the employment of obsolete techniques and technologies are the main reasons identified for the low TE scores. However, there many industries within this cluster which had high individual TE scores. This reinforces the scope for improvement within this industry. The marked presence of educated, young entrepreneurs is a definite indication of this industry's continued potential to provide sustainable livelihoods in the future.Keywords

Phenology of trees was studied in a dry deciduous forest (Tadoba National Park) in Chandrapur, Maharashtra state during 1996 to 1998. Out of four species Syzygium cumini (L) Skeels, Mangifera indica L.; Glochidion zeylanicum (Gaertn.) Juss. and Bauhinia malabarica Roxb. were evergreen. Leaf shedding was highest (91.67%) from February to April in 48 tree species. Flowering was from March to May and maximum in April. Possible reasons for leaf fall and flowering in tropical plants during hot season, include day length, abrupt drop in temperature, moisture stress or decreased water availability and change in incident radiation. Leaf fall during the dry season would offer good conditions for seed dispersal. Two fruiting peaks were in February and July. Fruiting periodicity has strong correlation with seed/ fruit dispersal mechanism and viability. Leaf flushing was maximum during the period from April to June. Leaf emergence is not correlated with the onset of rainy season but rather precedes its onset, often coinciding with flowering.Keywords

Alappuzha is the only district in Kerala state without natural forests. Therefore, sacred groves of this region attract utmost attention as they are the only remnants of natural forests once present. An exhaustive survey carried out in Alappuzha district revealed the presence of 1128 sacred groves varying in extent. Plant species numbering 687 were recorded from the sacred groves covering an area of 83.55 ha of Alappuzha district. They belonged to 493 genera and 127 families. Many valuable medicinal plants and wild relatives of cultivated species have been recorded which are important in species improvement programmes. Twenty-seven species were found to be endemic to Western Ghats. Most of the sacred groves in Alappuzha were proved to be invaluable resource pockets of floristic diversity. Many sacred groves in the district face threat due to the dense human population and change in socio-economic status. Break up of ancestral joint family system to nuclear families is the major reason for deterioration of these valuable resources. 'Ulladans', the tribal community collect canes and firewood indiscriminately. Overexploitation of the resources by them has lead to its retrogression to a great extent. Removal of litter alongwith the seeds from the floor has also resulted in retrogression by hindering the natural regeneration process. Exotic weeds namely, Mikania micrantha, Lantana camera and Chromolaena odorata overgrow the native species and play a major role in degradation. A detailed database on important sacred groves containing all the vital information including soil type, nutritional status, flora, fauna, plant associations, population structure, cultural and religious aspects and management operations will help in prescribing site specific conservation strategy.Keywords

A preliminary investigation on macrobenthic insect larvae of the Sankosh River and its permanent headwater streams carried out during the period from 2009 to 2010 has revealed significant results on the assemblages of various ecologically sensitive insect taxa. Beatidae, Simuliidae, Hydropsychidae, Chironomidae and Heptageniidae were the dominant taxa among the total of 37 insect families and Ephemeroptera, Diptera and Trichoptera were the dominant taxa among the total of 9 insect orders. Order Trichoptera was the richly represented taxa with 9 insect families followed by Diptera with 6 families and Hemiptera and Odonata with 5 families each. The abundance (%) of Ephemeroptera, Plecoptera and Trichoptera (EPT) taxa which account for 60.70% than that of all the other taxa was highly significant. A fairly good Biological Monitoring Working Party (BMWP) Score with an average of 50.31 out of the total 1308 was obtained for the 26 sampling stations, indicating relatively good water quality of the river system. The study, therefore, revealed the importance of aquatic macrobenthic insect diversity and its monitoring for better management of the river ecosystem.Keywords
