Forest inventory is the systematic collection of data and forest information for assessment or analysis. An estimate of the value and possible uses of timber is an important part of the broader information required to sustain ecosystems. When taking forest inventory the following are important things to measure and note: species, diameter at breast height (DBH), height, site quality, age, and defects. From the data collected one can calculate the number of trees per acre, the basal area, the volume of trees in an area, and the value of the timber. Inventories can be done for other reasons than just calculating the value. A forest can be cruised to visually assess timber and determine potential fire hazards and the risk of fire. The results of this type of inventory can be used in preventive actions and also awareness. Wildlife surveys can be undertaken in conjunction with timber inventory to determine the number and type of wildlife within a forest.
The aim of the statistical forest inventory is to provide comprehensive information about the state and dynamics of forests for strategic and management planning. Merely looking at the forest for assessment is called taxation. (Full article...)

The station is located 40 kilometres (25 mi) from the mouth of the Alta River, and it receives most of its water from the great Finnmarksvidda plateau. Below the power station, the river has salmon, and is a good fishing river. The station consists of two generators, at 100 megawatts (130,000 hp) and 50 MW (67,000 hp), respectively. The station utilises a 185 metres (607 ft) fall from the dam at the end of the 18 km (11 mi) long reservoirVirdnejávri. From the 145 m (476 ft) tall Virdnejávr Dam to the end of the power station the river is dry for about 2 km (1.2 mi). It is the tallest dam in the country. (Full article...)
Kaptai Dam (Bengali: কাপ্তাই বাঁধ) is on the Karnaphuli River at Kaptai, 65 km (40 mi) upstream from Chittagong in Rangamati District, Bangladesh. It is an earth-fill embankment dam with a reservoir (known as Kaptai Lake) with water storage capacity of 6,477 million cubic metres (5,251,000 acre⋅ft). The primary purpose of the dam and reservoir was to generate hydroelectric power. Construction was completed in 1962, in then-East Pakistan. The generators in the 230 MW (310,000 hp) Karnafuli Hydroelectric Power Station were commissioned between 1962 and 1988. It is the only hydroelectric power station in Bangladesh. (Full article...)

The history of plant systematics—the biological classification of plants—stretches from the work of ancient Greek to modern evolutionary biologists. As a field of science, plant systematics came into being only slowly, early plant lore usually being treated as part of the study of medicine. Later, classification and description was driven by natural history and natural theology. Until the advent of the theory of evolution, nearly all classification was based on the scala naturae. The professionalization of botany in the 18th and 19th century marked a shift toward more holistic classification methods, eventually based on evolutionary relationships. (Full article...)
