Recognition of habitats and conditions of species presences in differentsituations can be effective in proper utilization of vegetation. Little is known about thevegetation composition of Boralan Mountain region located in North West of Iran in theborder of Turkey and Azerbaijan with the altitude range of 800-2000m. The aim of thisstudy therefore was to investigate the floristic composition qua...

In 1998, a revolutionary system of angiosperm classification, the Angiosperm Phylogeny Group system was published. Meanwhile, another new system of classification of angiosperms, the eight-class system was proposed by C. Y. Wu and colleagues based on long term work on the flora of China. The Flora Reipublicae Popularis Sinicae project was initiated in 1959 and completed by 2004. It is the large...

Oceanic archipelagos often hold very specialized floras with high degrees of endemism. These floras are frequently highly vulnerable to disturbance by natural causes and human intervention. The Juan Fernandez Islands (Chile) in the Pacific Ocean are a small archipelago of only three islands. Since discovery in 1574 by Juan Fernandez, human activities have altered floristic composition and survi...

The floristic composition and structure of the Dry Afromontane Forest at Bale Mountains National Park was studied from July 2003 to June 2004. A total of 90 plots were established at three sites (Adelle, Boditi and Gaysay) at an altitudinal range of 3010–3410 m. The cover abundance values, density, and diameter at breast height and list of species were recorded in each plot. About 230 species b...

One of the main steps in road and railway embankment restoration is the spreading of previously removed topsoil, which provides an input of seeds, organic matter and microorganisms and encourages the establishment of a vegetation cover, essential to stabilise the embankment and blend it with the landscape. However, topsoil is a scarce resource, prompting the search for economic alternatives wit...

(Floristic composition, diversity and structure of the “cerrado” sensu stricto on rocky soils in northern Goiás and southern Tocantins, Brazil). The “cerrado” sensu stricto is a savanna woodland physiognomy which occupies most of central Brazil, with the degree of canopy cover varying from 10% to 60% at a site with trees reaching up to seven meters high. It occurs mostly on deep and well-draine...

The Kashmir Himalaya, being nestled within north-western folds of the Himalaya, harbours a rich floristic diversity of immense scientific interest and enormous economic potential. Though scientific studies on the floristic diversity in the Kashmir Himalaya have been started about two centuries ago, yet they fall short of the requirements needed urgently in the post-Rio Summit. In fact, at the s...
