Flora Of Pakistan
Pakistan's native flora reflects its varied climatic zones, which range from arid and semi-arid to temperate and tropical. For further details of habitats, see Ecoregions of Pakistan, Forestry in Pakistan and Wildlife of Pakistan. Distribution Northern highlands and valleys Pakistan has conifer forests in most of the northern and north-western highlands. These occur from 1,000 to 4,000 m altitudes. Swat, Upper Dir, Lower Dir, Malakand, Mansehra and Abbottabad districts of Khyber Pakhtunkhwa (formerly North-West Frontier Province) are the main areas covered with coniferous forests. Pindrow fir (''Abies pindrow'') and Morinda spruce ('' Picea smithiana'') occupy the highest altitudes, deodar (''Cedrus deodara'') and blue pine ('' Pinus wallichiana''), the intermediate heights, and chir pine (''Pinus roxburghii''), occupy the lower areas. Eastern plains and deserts In most of Punjab and Sindh, the Indus plains have many fluvial landforms that support various natural biom ...

Tree In Sant Nenuram Ashram
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, e.g., including only woody plants with secondary growth, only plants that are usable as lumber, or only plants above a specified height. But wider definitions include taller palms, tree ferns, bananas, and bamboos. Trees are not a monophyletic taxonomic group but consist of a wide variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some trees reaching several thousand years old. Trees evolved around 400 million years ago, and it is estimated that there are around three trillion mature trees in the world currently. A tree typically has many secondary branches supported clear of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pinus Roxburghii
''Pinus roxburghii'', commonly known as chir pine or longleaf Indian pine, is a species of pine tree Native plant, native to the Himalayas. It was named after William Roxburgh. Description ''Pinus roxburghii'' is a large tree reaching with a trunk diameter of up to , exceptionally . The Bark (botany), bark is red-brown, thick and deeply fissured at the base of the trunk, thinner and flaky in the upper crown. The leaves are needle-like, in fascicles of three, very slender, long, and distinctly yellowish green. The conifer cone, cones are ovoid conic, long and broad at the base when closed, green at first, ripening glossy chestnut-brown when 24 months old. They open slowly over the next year or so, or after being heated by a wildfire, forest fire, to release the seeds, opening to broad. The seeds are long, with a wing, and are wind-Seed dispersal, dispersed. Similar species ''Pinus roxburghii'' is closely related to ''Pinus canariensis, P. canariensis'' (Canary I ...

Reed Bed
A reedbed or reed bed is a natural habitat found in floodplains, waterlogged depressions and estuaries. Reedbeds are part of a succession from young reeds colonising open water or wet ground through a gradation of increasingly dry ground. As reedbeds age, they build up a considerable litter layer that eventually rises above the water level and that ultimately provides opportunities in the form of new areas for larger terrestrial plants such as shrubs and trees to colonise. Artificial reedbeds are used to remove pollutants from greywater, and are also called constructed wetlands. Types Reedbeds vary in the species that they can support, depending upon water levels within the wetland system, climate, seasonal variations, and the nutrient status and salinity of the water. ''Reed swamps'' have 20 cm or more of surface water during the summer and often have high invertebrate and bird species use. ''Reed fens'' have water levels at or below the surface during the summer and are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Indus
The Indus ( ) is a transboundary river of Asia and a trans- Himalayan river of South and Central Asia. The river rises in mountain springs northeast of Mount Kailash in the Western Tibet region of China, flows northwest through the disputed Kashmir region, first through the Indian-administered Ladakh, and then the Pakistani administered Gilgit Baltistan, Quote: "Kashmir, region of the northwestern Indian subcontinent. It is bounded by the Uygur Autonomous Region of Xinjiang to the northeast and the Tibet Autonomous Region to the east (both parts of China), by the Indian states of Himachal Pradesh and Punjab to the south, by Pakistan to the west, and by Afghanistan to the northwest. The northern and western portions are administered by Pakistan and comprise three areas: Azad Kashmir, Gilgit, and Baltistan, ... The southern and southeastern portions constitute the Indian state of Jammu and Kashmir. The Indian- and Pakistani-administered portions are divided by a "line of c ...

Riparian Zone
A riparian zone or riparian area is the interface between land and a river or stream. In some regions, the terms riparian woodland, riparian forest, riparian buffer zone, riparian corridor, and riparian strip are used to characterize a riparian zone. The word ''riparian'' is derived from Latin ''wiktionary:ripa, ripa'', meaning "bank (geography), river bank". Riparian is also the proper nomenclature for one of the terrestrial biomes of the Earth. Plant habitats and communities along the river margins and banks are called riparian vegetation, characterized by aquatic plant, hydrophilic plants. Riparian zones are important in ecology, environmental resource management, and civil engineering because of their role in soil conservation, their habitat biodiversity, and the influence they have on terrestrial animal, terrestrial and semiaquatic fauna as well as aquatic ecosystems, including grasslands, woodlands, wetlands, and even non-vegetative areas. Riparian zones may be natural ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Capparis Aphylla
''Capparis decidua'', commonly known as karira, is a useful plant in its marginal habitat. Description It is a small much-branched tree or shrub.

Tharparkar
Tharparkar (Dhatki language, Dhatki/; , ), also known as Thar, is a district in Sindh province in Pakistan, headquartered at Mithi. Before Indian independence it was known as the Thar and Parkar (1901–1947) or Eastern Sindh Frontier District (1860–1901). The district is the largest in Sindh, and has the largest Hinduism in Pakistan, Hindu population in Pakistan. It has the lowest List of Pakistani Districts by Human Development Index, Human Development Index rating of all the districts in Sindh. Currently the Sindh government is planning to divide the Tharparkar district into Tharparkar and Chhachro District, Chhachro district. History The name Tharparkar originates from a portmanteau of the words Thar (referring to the Thar Desert), and parkar (meaning "to cross over"). The Thar region was historically fertile, although it was mostly desertified between 2000 BCE and 1500 BCE. Before its desertification, a tributary of the Indus River was said to flow through th ...

Deserts And Xeric Shrublands
Deserts and xeric shrublands are a biome defined by the World Wide Fund for Nature. Deserts and xeric (Ancient Greek 'dry') shrublands form the largest terrestrial biome, covering 19% of Earth's land surface area. Ecoregions in this habitat type vary greatly in the amount of annual rainfall they receive, usually less than annually except in the margins. Generally evaporation exceeds rainfall in these ecoregions. Temperature variability is also diverse in these lands. Many deserts, such as the Sahara Desert, Sahara, are hot year-round, but others, such as East Asia's Gobi Desert, become quite cold during the winter. Temperature extremes are a characteristic of most deserts. High daytime temperatures give way to cold nights because there is no insulation provided by humidity and cloud cover. The diversity of climatic conditions, though quite harsh, supports a rich array of habitats. Many of these habitats are ephemeral in nature, reflecting the paucity and seasonality of avail ...

Tropical And Subtropical Grasslands, Savannas, And Shrublands
Tropical and subtropical grasslands, savannas, and shrublands is a terrestrial biome defined by the World Wide Fund for Nature. The biome is dominated by grass and/or shrubs located in semi-arid to semi- humid climate regions of subtropical and tropical latitudes. Tropical grasslands are mainly found between 5 degrees and 20 degrees in both North and south of the Equator. Description Grasslands are dominated by grasses and other herbaceous plants. Savannas are grasslands with scattered trees. Shrublands are dominated by woody or herbaceous shrubs. Large expanses of land in the tropics do not receive enough rainfall to support extensive tree cover. The tropical and subtropical grasslands, savannas, and shrublands are characterized by rainfall levels between per year. Rainfall can be highly seasonal, with the entire year's rainfall sometimes occurring within a couple of weeks. African savannas occur between forest or woodland regions and grassland regions. Flora includes acacia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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] |
