Forestry In Sri Lanka
Sri Lanka exhibits a remarkable biological diversity and is considered to be the richest country in Asia in terms of species concentration. In 2019 a total area of 16.5% of Sri Lanka was forested. In 2010, it was 28.8% (and 32.2% in 1995.) 9.0% of Sri Lanka's forests are classified as primary forest (the most biodiverse form of forest and the biggest carbon sinks on Earth). Sri Lanka's forests contain 61 million metric tons of carbon in living forest biomass (in 2010). Between 1990 and 2005 alone, Sri Lanka lost 17.7% of its forest cover. History Sri Lanka continental separated from the south eastern tip of peninsular India by the more than 20 m deep Palk Strait. There had been repeated land connections with India across this strait during successive glacial periods, the last being between 10,000 and 20,000 years ago when the sea level was about 120m below the present level creating a 140 km wide land bridge. Notwithstanding these intermittent land connections with Indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sri Lanka
Sri Lanka, officially the Democratic Socialist Republic of Sri Lanka, also known historically as Ceylon, is an island country in South Asia. It lies in the Indian Ocean, southwest of the Bay of Bengal, separated from the Indian subcontinent, Indian peninsula by the Gulf of Mannar and the Palk Strait. It shares a maritime border with the Maldives in the southwest and India in the northwest. Sri Jayawardenepura Kotte is the legislative capital of Sri Lanka, while the largest city, Colombo, is the administrative and judicial capital which is the nation's political, financial and cultural centre. Kandy is the second-largest urban area and also the capital of the last native kingdom of Sri Lanka. The most spoken language Sinhala language, Sinhala, is spoken by the majority of the population (approximately 17 million). Tamil language, Tamil is also spoken by approximately five million people, making it the second most-spoken language in Sri Lanka. Sri Lanka has a population of appr ...

Sri Lanka Montane Rain Forests
The Sri Lanka montane rain forests is an ecoregion found above 1,000 m in the central highlands of Sri Lanka. Owing to their rich biodiversity, this region is considered to be a super-hotspot within endemic hotspots of global importance. These forests are cooler than lowland forests and therefore they have ideal conditions for growth of cloud forests. These forests classifications tropical sub montane forest, tropical sub-montane and tropical upper montane. Half of Sri Lanka's endemic flowering plants and 51 percent of the endemic vertebrates are restricted to these forests. More than 34 percent of Sri Lanka's endemic trees, shrubs, and herbs can only be found in this ecoregion. Twisted, stunted trees are a common sight in these forests, together with many varieties of orchids, mosses and ferns. The trees of montane rain forests grow to a height 10–15 meters, shorter than the lowland rain forest trees. These high altitude forests are the catchment area for most of Sri Lanka's ...

Fungus
A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as one of the kingdom (biology)#Six kingdoms (1998), traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or Protozoa and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of motility, mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 spe ...

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 (WWF). 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 forests are home to more species than any other terrestrial ecosystem on Earth: Half of the world's species may live in these forests, where a square kilometer may be home to more than 1,000 tree species. These forests are found around the world, particularly in the Indo-Malayan Archipelago, the Amazon Basin, and the African Congo Basin. The perpetually warm, wet climate makes these environments more productive than any ot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Savanna
A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) biome and 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. Four savanna forms exist; ''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 forests.Manoel Cláudio da ...

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. '' Manilkar ...

Dryland Farming
Drylands are defined by a scarcity of water. Drylands are zones where precipitation is balanced by evaporation from surfaces and by transpiration by plants (evapotranspiration). The United Nations Environment Program defines drylands as tropical and temperate areas with an aridity index of less than 0.65."Millennium Ecosystem Assessment, 2005. Drylands Systems". Chapter 22 in: ''Ecosystems and Human Wellbeing: Current State and Trends'', Volume 1. Island Press. Drylands can be classified into four sub-types: * Dry sub-humid lands * Semi-arid lands * Arid lands * Hyper-arid lands Some authorities regard hyper-arid lands as deserts (United Nations Convention to Combat Desertification) although a number of the world's deserts include both hyper-arid and arid climate zones. The UNCCD excludes hyper-arid zones from its definition of drylands. Drylands cover 41.3% of the Earth's land surface, including 15% of Latin America, 66% of Africa, 40% of Asia, and 24% of Europe.

Tropical And Subtropical Dry Broadleaf Forests
The tropical and subtropical dry broadleaf forest is a habitat (ecology), 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 millimeters 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 (forest), 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 ever ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
