Abstract: Automatic 3D extraction of building roofs from remotely sensed data is important for many applications including city modelling. This paper proposes a new method for automatic 3D roof extraction through an effective integration of LIDAR (Light Detection And Ranging) data and multispectral orthoimagery. Using the ground height from a DEM (Digital Elevation Model), the raw LIDAR points are seperated into two groups. The first group contains the ground points that are exploited to constitute a ' ground mask ' . The second group contains the non-ground points which are segmented using an innovative image line guided segmentation technique to extract the roof planes. The image lines are extracted from the grey scale version of the orthoimage and then classified into several classes such as ' ground ' , ' tree ' , ' roof edge ' and ' roof ridge ' using the ground mask and colour and texture information from the orthoimagery. During segmentation of the non-ground LIDAR points, the lines from the latter two classes are used as baselines to locate the nearby LIDAR points of the neighbouring planes. For each plane a robust seed region is thereby defined using the nearby non-ground LIDAR points of a baseline and this region is iteratively grown to extract the complete roof plane. Finally, a newly proposed rule-based procedure is applied to remove planes constructed on trees. Experimental results show that the proposed method can successfully remove vegetation and so offers high extraction rates.

Keywords: Home garden trees, Artocarpus heterophyllus, Ailanthus triphysa, Tectona grandis, Volume tables.
Abstract: Teak (Tectona grandis Linn.), jack (Artocarpus heterophyllus Lamk.), anjily (A. hirsutus Lamk.), matty (Ailanthus triphysa Dennst.) and mango (Mangifera indica Linn.) trees are commercially and economically important tree species in home gardens of Kerala. Different types of volume prediction equations were developed for each species through regression analysis, using data on diameter (m) at breast-height level (1.37 m from ground) of sample trees before felling and corresponding volume (m?) of commercial timber measured after felling. Volume of a tree refers to that under-bark of logs or billets with mid-girth (over-bark) 40cm and above, in case of teak, matty and mango trees. It refers to that under-sapwood (volume after removing sapwood) of logs with mid-girth (over-bark) 60 cm and above, in the case of jack and anjily trees. Using the best fitted equation selected from the set of 27 equations estimated for each species, volume estimates were predicted for those values of diameter corresponding to different values of girth at breast height from 60cm upwards with an interval of 5cm. Tabulating the girth in cm and volume in m?, volume tables were prepared for each species. The tables provide volume estimates corresponding to different values of girth at breast-height of trees which can easily be measured at site. The tables are useful to tree growers and purchasers, for obtaining an estimate of volume in a tree by referring the tables without felling the tree.

Abstract: The present study deals with breaking the seed dormacy by various physical and chemical agents and establishment of seedlings of Adansonia digitata and Cochlospermum religiosum. In A. digitata, pre treatment with concentrated sulphuric acid for 12hrs exhibited 68% germination which was further enhanced up to 90.67% by post treatment soaking in 0.1M glucose solution. C. religiosum exhibited 32% germination with pre treatment of sulphuric acid for 25min and with post treatment soaking in 0.1M glucose solution showed 54.67% germination. Seedling survival was also found to be more in the combination treatment of sulphuric acid and 0.1M glucose solution (A.digitata-81.33%) than pure sulphuric acid treatment.

Abstract: Rock types, soil profile and nutrient status and the vegetation study carried out in degraded area of Aravalli selecting five villages along the hill in a stretch of about 40km. Calc amphibolite gneiss, quartzitic schist, granitic gneiss, calc schist, garnetiferous mica schist, bar conglomerate schist and pegmatite were the dominant rock types in the area. Under the process of weathering these rocks provided sandy loam soils. The rainfall and wind facilitated erosion and the soil transported and deposited in the pediment area resulted in an increased soil depth. Desertification also occurred at some places. Degradation pattern shows less availability of vegetation cover and needs to rehabilitate these hills. In deeper soil layers, increased soil pH was associated with sensitive sandy soils which might be responsible for basic characters of these soils. The soil content and depth increased with different rocks VIZ: calc amphibolites gneiss<quartzitic schist<garnetiferous mica schist< bar congiomerate schist<feldspathic schist<granitic gneiss supporting herbaceous vegetation.

Abstract: Sloth bears inhabits different habitat types accross Indian subcontinent and lives in varied sized dens made up of big boulders. The present survey recorded 109 active denning sites in Pendra and Marwahi ranges of North Bilaspur Forest Division. Most of the bear denning sites were located around Ficus virens, F. tinctoria, Bauhinia sp. Diospyros melanoxylon, Boswellia serrata and Lannea coromandelica trees. All dens were recorded from degraded forests. Water availability for bears was plentiful and most of the denning sites had accessibility to water at a short distance. Similarly, most of the denning sites were located at a reasonable distance from the nearest human habitation. Majority of recorded dens faced south followed by southeast and northeast directions. Interestingly, other animals were also observed sharing denning sites. Occasionaly sloth bears were seen shifting their sites. The sloth bear preferred to come out from their dens early in the evening but seen waiting until dark to commence before going for foraging. Sloth bear also relax for 30-45 minutes outside the dens before entering into it. Majority of observed bears entered into their dens early in the morning much before human starts entering into forests. Annual outside mean temperature as well as inside mean temperature of dens varied significantly during day time.

Abstract: An experiment was conducted to assess the effect of solid content of urea formaldehyde (UF) adhesive on the compression parameters of finger jointed sections of Eucalyptus wood. Three concentrations designated as UF1, UF2 and UF3 had solid contents of 36.8%, 44.9% and 57.6% respectively. All three concentrations showed good efficiency under compression parallel to grain when small sections were joined with finger jointing. The study illustrated that a UF concentrations at 36.8% to 57.6% solid content range can perform equally well when eucalyptus sections are joined with the finger profile used in the study.

Abstract: Spermoplane micro flora of teak (Tectona grandis) seeds were recorded in the inflorescence, immature and mature stages of fruits. During the seed setting process Fusarium sp. shows systemic infection. Simultaneously some seed boring insects like Pagyda salvalis, Dichocrosis punctiferalis and D.pendamalis were also found associated with the teak fruits. Due to attack of these pathogens and insects, the fruiting in TSO ' s and SPA ' s are very less. One field experiment, using biopestcides (Baccillus thuringiensis, B.amyloliquefaciens), insecticides (Monocrotophos), fungicide (Bavistin), trace elements (Rallis tracel-2) and growth harmone (Planofix) in different combinations were applied in 16 years old TSO in Nandigram, Seoni, M. P.. The result of the experiment showed maximum number of fruits and weight of teak fruits in the treatment of Monocrotophos (0.05%)+Bavistin (0.2%), the insect and fungal damage was also less in the treatment. Whereas other treatment does not show significant result. Therefore, application of Monocrotophos (0.05%) + Bavistin (0.2%) in the month of July and 2nd dose during 1st week of August can enhance fruit productivity in TSO ' s.

Abstract: Phyto-mass/carbon of under-storey vegetation play a significant role in carbon dynamics, wildlife habitat quality, biodiversity, soil conservation, soil organic carbon, soil fertility, etc. Above ground phyto-mass/carbon of under-storey vegetation consisting of components like shrubs, herbs, litter, and humus of sal (Shorea robusta) forest has been assessed using ground observations and these contribute (0)1-3% in total above ground phytomass. This assessment is based using satellite remote sensing data for characterising forests for homogeneous stratification map based on forest type, forest density and physiography. Above ground phytomass in shrubby layer varied from 1.76 t/ha in ' sal-teak mixed ' (Tectona grandis) with 60-80% density to 5.16 ?SE 1.78 t/ha in ' pure sal ' with >80% density. Phytomass in herbaceous layer was almost nil in the case of very high canopy density (>80%) in ' pure sal ' forest, ' sal teak mixed ' and ' sal mixed ' forests. The highest phytomass 1.93?SE 0.17 t/ha is reported in the ' pure sal ' (10-40% density) followed by ' hill sal ' (10-40% density) 1.49?SE 0.03 t/h and 1.27?SE 0.01 t/ha in ' hill sal ' with 40-60% density. The open (10-40% density) to moderately degraded (40-60%) ' pure sal ' forests have high potential for carbon sequestration. The carbon density in shrubs, herbs, and litter- humus layer showed variable trends with different forest density strata except litter-humus in ' pure sal and sand mixed ' forests. The phytomass contribution of exotic shrub such as Lantana camara in the degraded forests would be useful for management planning.
