The present paper reports the emergence of sal heartwood borer, Hoplocerambyx spinicornis Newman (Coleoptera: Cerambycidae) and its infestation in Dindori Forest Division, Dindori, Madhya Pradesh, during the year 2012-2014.Out of the six sal forest ranges, viz. Bajag, East Karanjia, West Karanjia, Garasarai, North Samnapur and South Samnapur, sal borer incidence was recorded in five ranges, and there was no borer attacked trees noticed in sal forests of Garasarai range during the study period.The emergence of borer beetles started during the year 2012. The data on borer infestations revealed that a total of 699 sal trees were affected during the year 2012 in three ranges, viz. Bajag, East Karanjia, and South Samnapur, 6139 during 2013 in four ranges, viz. Bajag, East Karanjia, West Karanjia, and South Samnapur, 29382 during 2014 in five ranges, viz.Bajag, East Karanjia, West Karanjia, North Samnapur and South Samnapur. The average sal borer incidence was 0.02 tree/ha, 0.11 tree/ha, 0.45 tree/ha during the year 2012, 2013 and 2014 respectively. The maximum number of borer affected sal trees was recorded to be in Type T7 and girth class 121-150 cm GBH. The number of borer affected sal trees and sal borer incidence recorded during the study period was correlated with meteorological data, such as temperature, relative humidity and rainfall. The data on borer incidence when correlated with minimum, maximum, and mean temperatures, relative humidity and rainfall showed significant (P<0.05) negative correlation with relative humidity (r = -0.927), other parameters exhibited no conclusive (P>0.05) difference. Trap-tree operation was conducted during the emergence period (June-July) of sal borer beetles, in different affected compartments of Forest Ranges, for its collection. A total number of borer beetles trapped were 1285 during the year 2013, collected from three ranges, whereas during the year 2014 and 2015 beetletrapped was 4440 and 79186 collected from four and five ranges of the Division respectively. The collection of borer beetles reduced its incidence which reflects the efficiency of Trap-tree operation in management of sal borer. The results are discussed in the light of the present findings.

The study deals with the floristic diversity assessment and vegetation composition analysis in various forest types from Hosur Forest division situated in Eastern Ghats of Southern India, in the state of Tamil Nadu. The study recorded 468 species of plants belonging to 283 genera and 91 families, including Angiosperms (464 species), Pteridophytes (3 species) and Bryophytes (1 species). Of the total, 94 species are trees, 12 are lianas, 70 are shrubs, 34 species are climbers, 194 species are herbs, sedges 7, grasses 21, ferns 3 and 1 species of moss. The five most abundant families in Hosur Forest Division were Fabaceae (45 spp.), Poaceae (34 spp.), Acanthaceae (30 spp.), Euphorbiaceae (28 spp.) and Rubiaceae (25 spp.). The quantitative features such as density and important value index (IVI) varied greatly among forest and in different forest types. In the present study, the diversity index of shrubs and herbs were found to be higher than that of trees. The maximum species diversity was recorded in Southern dry mixed deciduous forest (SDMDF) followed by Southern Thorn Forest (STF) and Southern Thorn Scrub (STS). The species diversity (H) was recorded the highest for SDMDF (5.61) followed by STF (5.18) and the lowest for STS (5.12). The presence of large number of higher girth class tree species and low number of sapling and seedling indicates that the present forests investigated are old and exhibiting low regeneration.

AbstractNonnative invasive plants (NNIP) have far-reaching effects on native ecosystems worldwide. Understanding the role of generalist seed dispersers in spreading NNIP across the landscape is important to the conservation of native ecosystems and to the management of NNIP. We studied white-tailed deer (Odocoileus virginianus) as a seed disperser in a mixed maritime pine (Pinus spp.) forests on Parris Island, SC, with particular interest in the dispersal of Chinese tallowtree [Triadica sebifera (L.) Small], a highly invasive tree species in the southeastern United States, which is a management concern on Parris Island, SC. We collected deer scat pellet groups along transects in two forest types: those that had recently been treated with silvicultural timber harvest (thinned) and those that have not been so treated (unthinned). Using two pellet-treatment methods, directly planting or rinsing and sorting, we determined that, out of 25 species grown under greenhouse conditions, 28% (n = 7) were nonnative, small-seeded, herbaceous species. However, T. sebifera was not identified in either of the two treatment methods. Recent forest thinning significantly affected the number of species determined in deer pellet groups (F = 8.37; df = 1; P < 0.01), with more native plant species identified in unthinned (x̄ = 25 ± 11) than in thinned (x̄ = 3 ± 10) forest stands (F = 5.33; df = 1; P = 0.02). Our results indicate that white-tailed deer are actively dispersing nonnative seeds but not those of T. sebifera or other woody NNIP.

The relationship between vegetation and selected soil characteristics in different monoculture forest types was investigated as part of a landscape restoration project after brown coal mining. Six forest types were selected: alder (Alnus sp.), spruce (Picea sp.), pine (Pinus sp.), larch (Larix sp.), long-term deciduous forest (Quercus robur, Tilia sp.), and forest created by spontaneous succession. These stands were classified into two age categories (younger and older). The soil attributes, C/N, TC, TN, pH, and A horizon depth were assessed. The observed species were categorized into functional groups by life history, life forms according to Raunkiær, and affinity to the forest environment. C/N ratio, humus thickness, and canopy cover were the main soil parameters affecting plant communities. The highest C/N values were recorded in Pinus and Larix stands, which were significantly different from deciduous and succession stands. The highest diversity index was noted in younger stands of Alnus and the lowest in younger stands of Picea. Intermediate values of the diversity index were achieved in successional stands at both age levels and in Larix and Alnus stands. The species belonging to a functional group was not an important factor in these habitat types. The species composition and vegetation change over time in the Alnus, long-life deciduous, and Larix stands show that these species are more suitable for forestry reclamation than spruce or pine. The study also emphasizes the great value of spontaneous succession areas as full-fledged alternatives to forestry reclamation.

The present paper deals with the study conducted to know the floristic diversity assessment and vegetation composition analysis in various forest types of Dharmapuri Forest division situated in Eastern Ghats of Southern India in the state of Tamilnadu. A total of 352 species of 233 genera and belonging to 79 families were recorded. The quantitative features such as density and important value index (IVI) varied greatly among forest and different forest types. In the present study the diversity index of shrubs and herbs were found to be higher than the tree species. The presence of high number of higher girth class of tree species and low number of sapling and seedling indicates that the present forest is old and exhibiting the low regeneration.
