Forestry In Sri Lanka
Sri Lanka is a relatively small continental island, it exhibits a remarkable diversity of forest types, which are among the biologically one of richest forests in Asia. In these forests plant species show extraordinary patterns of localized distribution. Sri Lanka's forest became one of highest density of species diversity in the world. (2.17 BioD index) Sri Lanka natural forest cover about 12,493 km2 (65,610 km2 total land area) 29.46% According to the National Red List said, Sri Lanka counts 253 land species, 245 species of butterflies, 240 birds, 211 reptiles, 748 evaluated vertebrates and 1,492 invertebrates. Forest coverage is about 70% tropical dry monsoon forests, 15% tropical moist monsoon forests and 5% tropical lower montane forests. By the dawn of the 19th century, Sri Lanka's forest cover was estimated at up to 70% of the total land area. Since then, the forest cover has decreased progressively over time. Significant loss of Sri Lanka's forest cover was first reporte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sri Lanka

Peninsular Malaysian Montane Rain Forests
The Peninsular Malaysian montane rain forests is an ecoregion on Malay Peninsula. It occupies the mountainous spine of the peninsula in Malaysia and southernmost Thailand. It is in the tropical and subtropical moist broadleaf forests biome. Geography The ecoregion occupies elevations above 1000 meters in the Titiwangsa Mountains, which form the mountainous backbone of the Malay Peninsula. It also includes ranges to the east in Kelantan, Terengganu, and Pahang states. The highest peak in the Titiwangsa Mountains is Mount Korbu at 2,183 meters elevation. Other peaks include Mount Tahan (2,188 m), the highest peak in peninsular Malaysia, and Mount Benum (2,130 m). The ecoregion is surrounded at lower elevations by the ecologically-distinct Peninsular Malaysian rain forests.Saw, Leng Guan. (2010).

Dry Grassland
The key characteristic of dry grasslands is that they have low-growing plants, causing the area to be quite open. They also have a mottled structure, which leads to a biome with sunny or semi-shaded areas. On top of that, their soil is relatively dry and nutrient-poor. There are, however, types of grasslands with a higher humus and nutrient content. The soil of these areas overlie acid rocks or deposits such as sands and gravels. Dry grasslands belong to different zones such as: the natural zonal or azonal/extrazonal vegetation and the semi-natural vegetation. Overall, there are 13 classes that fall under dry grasslands. Dry grassland areas are very important to biodiversity as they contain a wide range of plant and animal species. European dry grasslands have the highest small-scale species densities amongst plant communities. This is why conservation efforts have become vital for dry grasslands, to ensure the continuance of its vast diversity and to help the many endangered speci ...

Tropical And Subtropical Moist Broadleaf Forests
Tropical and subtropical moist broadleaf forests (TSMF), also known as tropical moist forest, is a subtropical and tropical forest habitat type defined by the World Wide Fund for Nature. Description TSMF is generally found in large, discontinuous patches centered on the equatorial belt and between the Tropic of Cancer and Tropic of Capricorn, TSMF are characterized by low variability in annual temperature and high levels of rainfall of more than annually. Forest composition is dominated by evergreen and semi-deciduous tree species. These trees number in the thousands and contribute to the highest levels of species diversity in any terrestrial major habitat type. In general, biodiversity is highest in the forest canopy. The canopy can be divided into five layers: overstory canopy with emergent crowns, a medium layer of canopy, lower canopy, shrub level, and finally understory. These forests are home to more species than any other terrestrial ecosystem: Half of the world's sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Savanna
A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. According to '' Britannica'', there exists four savanna forms; ''savanna woodland'' where trees and shrubs form a light canopy, ''tree savanna'' with scattered trees and shrubs, ''shrub savanna'' with distributed shrubs, and ''grass savanna'' where trees and shrubs are mostly nonexistent.Smith, Jeremy M.B.. "savanna". Encyclopedia Britannica, 5 Sep. 2016, https://www.britannica.com/science/savanna/Environment. Accessed 17 September 2022. Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in for ...

Sri Lanka Dry-zone Dry Evergreen Forests
The Sri Lanka dry-zone dry evergreen forests are a tropical dry broadleaf forest ecoregion of the island of Sri Lanka. Geography The ecoregion covers an area of , about 75%, of the island of Sri Lanka, with the exception of the islands' southwestern corner and Central Highlands, home to the Sri Lanka lowland rain forests and Sri Lanka montane rain forests ecoregions, respectively, and the northern Jaffna Peninsula, which is part of the Deccan thorn scrub forests ecoregion. The topography is generally low, and the landscape is dotted with isolated inselbergs. The highest of these inselbergs is Ritigala (766 meters), which lies north of the Central Highlands. Climate The ecoregion receives 1500–2000 mm of rainfall annually. Most rain falls during the December-to-March northeast monsoon season, and it is mostly dry the rest of the year. Flora The ecoregion has several plant communities. * Mixed dry evergreen forest is the most widespread plant community. ''Manilkara h ...

Dryland Farming
Dryland farming and dry farming encompass specific agricultural techniques for the non-irrigated cultivation of crops. Dryland farming is associated with drylands, areas characterized by a cool wet season (which charges the soil with virtually all the moisture that the crops will receive prior to harvest) followed by a warm dry season. They are also associated with arid conditions, areas prone to drought and those having scarce water resources. Process Dryland farming has evolved as a set of techniques and management practices used by farmers to continually adapt to the presence or lack of moisture in a given crop cycle. In marginal regions, a farmer should be financially able to survive occasional crop failures, perhaps for several years in succession. Survival as a dryland farmer requires careful husbandry of the moisture available for the crop and aggressive management of expenses to minimize losses in poor years. Dryland farming involves the constant assessing of the amo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical And Subtropical Dry Broadleaf Forests
The tropical and subtropical dry broadleaf forest is a habitat type defined by the World Wide Fund for Nature and is located at tropical and subtropical latitudes. Though these forests occur in climates that are warm year-round, and may receive several hundred centimeters of rain per year, they have long dry seasons that last several months and vary with geographic location. These seasonal droughts have great impact on all living things in the forest. Deciduous trees predominate in most of these forests, and during the drought a leafless period occurs, which varies with species type. Because trees lose moisture through their leaves, the shedding of leaves allows trees such as teak and mountain ebony to conserve water during dry periods. The newly bare trees open up the canopy layer, enabling sunlight to reach ground level and facilitate the growth of thick underbrush. Trees on moister sites and those with access to ground water tend to be evergreen. Infertile sites also tend t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
