Assessment of air pollution sensitivity of some selected tree species of busiest roads of Lahore city

The research includes Air Pollution Tolerance Index (APTI) of commonly occurring tree of Mall road and Jail road of Lahore, Pakistan. In order to find out APTI, four species were selected i.e. Alstonia scholaris (L.) R.Br., Callistemon citrinus (Curtis) Skeels, Ficus religiosa L. and Morus alba L. The experiment was carried out by taking four […]

Comparative leaf morphometrics of two urban tree species: an assessment to air pollution impacts

Leaf-size indices of two urban tree species namely: Pterocarpus indicus forma echinatus Willd. and Sweitenia macrophylla King growing in polluted and non-polluted areas of Cagayan de Oro City, Philippines were compared to verify if air pollution could directly affect leaf morphology.  The streets with the heaviest influx of vehicles per day were considered as the […]

Tree Species Composition, Richness and Diversity of the Mount Matutum Protected Landscape (MMPL), Philippines

Forest trees assemblage and distribution were assessed through Plot Method across disturbed and undisturbed habitat gradients (500-1712 masl) representing lowland, montane and mossy forests of Mount Matutum Protected Landscape (MMPL). Species diversity through composition, richness and distribution along with endemism and conservation status was also determined. 1349 stems (≥10 cm DBH) were recorded; resolved into […]

Diversity and regeneration status of tree species in the sacred groves of central western Ghats, India

Tree species diversity and their regeneration status were investigated in three sacred groves of Somwarpet, Central western Ghats using the random quadrat method. A total of 114 arboreal species was identified belonging to 40 families among three sacred groves. Relatively a higher density of 463.44 – 853.44 individuals per hectare and a higher basal area […]

Population structure and traditional management patterns of two threatened medicinal tree species (Garcinia lucida and Pausinystalia johimbe) in the southern humid forest of Cameroon

Garcinia lucida and Pausinystalia johimbe are two medicinal tree species well-known in southern Cameroon as they provide non-timber forest products. Particularly, their barks and sometimes fruits, seeds and leaves of G. ludica are used to cure many ailments in local communities. Unfortunately, natural stands of both species are seriously threatened in Cameroon. The objectives of […]

Effect of leaf litter on seed dormancy, germination and seedling survival of three tropical forest tree species in Ghana

The exact role of leaf litter and its interaction with irradiance in tree species regeneration is still poorly understood. We conducted a three – factor full factorial plant house experiment to determine the effect of leaf litter and irradiance (with particular interest in their interaction) on germination and seedling survival of three tropical tree species, […]

Natural regeneration potential of key livelihood tree species under different land use types within Omo Biosphere Reserve, Nigeria

Impact of land use change on the natural regeneration potential of key livelihood tree species in Omo biosphere reserve was examined by evaluating soil seed banks under the Strict Nature Reserve (SNR); three chronosequences of arable farmland – AF1, AF2 and AF3, reflecting short, medium, and long period of cultivation respectively; Nuclea diderrichii Plantation (NDP), […]

Diversity and distribution of tree species in the hills of Chittagong Metropolitan Area, Bangladesh

Chittagong City is surrounded by several hills which were abundant with biodiversity but continuously destroying now due to high population pressure and development. To explore current status of species diversity and distribution, we conducted this study from November, 2013 to October, 2014 in Chittagong Metropolitan Area (CMA). Wherein 780 trees belong to 65 species were […]

Characterization of diameter distribution of some tree species from Gilgit-baltistan using weibull distribution

Forty stands were sampled to investigate the overall diameter size classes of four dominant tree species of some forests from Gilgit-Baltsitan. On the basis of overall density of individuals of a species the size class structure was derived. Pinus wallichiana A.B.Jacks .occupied 128±21.1 mean stems ha-1, Picea smithiana (Wall.)Boiss. attained 121±5 mean stems ha-1 ,Betula […]

Using selected biophysical parameters and remote sensing in tree species diversity and size monitoring in natural woodlands under non-rainfall limitation conditions

This study assessed the feasibility of using selected biophysical parameters (Slope, altitude, aspect, soil pH, phosphorous, nitrogen and carbon) and remote sensing to monitor tree species diversity and size in an example of natural woodlands in a non-rainfall limitation region. The assessment was done across three different land use systems namely communal, old resettlement and […]
