Thousands of years ago, man and tree teamed up together, each benefiting from the others company. But this solid and enduring association has so far proved a thoroughly rewarding experience for men who get food, fuel, fresh air, medicine, shade, shelter, scenic beauty, house building material, wood for furniture, economic prosperity and environmental preservation from the trees simultaneously, and quite independently. Had there not been the trees, life on this planet would have been doomed to extinction long ago. Huge increase in pollution and population has thus certainly multiplied the importance of tree plantation and afforestation in recent times.
See Article History Alternative Titles: Arecaceae, Palmae Palm, any member of the Arecaceae, or Palmae, the single family of monocotyledonous flowering plants of the order Arecales. Distribution The great centres of palm distribution are in America and in Asia from India to Japan and south to Australia and the islands of the Pacific and Indian oceans, with Africa and Madagascar as a third but much less important palm region.
The northernmost palm is the European fan palm Chamaerops humiliswhich grows about the Mediterranean in Europe and North Africa; the southernmost is the nikau palm Rhopalostylis sapidaof New Zealand and the Chatham Islands.
Although there are species with extensive ranges, especially in America, most are restricted in range, and those of islands, in particular, are frequently found nowhere else. One species, Maxburretia gracilis, is limited to a few limestone outcroppings in the Langkawi Islands off the Malay Peninsula.
The island of New Caledonia has 17 genera and 32 species of palms, all of them endemic. The palms of Madagascar are not yet well known, but species belonging to 21 genera are recorded and Importance of trees in our life least 14 of the genera are found only on the island.
No species, except the European fan palm and the pantropical cultivated coconut Cocos nuciferaoccurs on more than one continent; the genera transcending continental bounds are Chamaerops in Europe and Africa, Elaeis oil palm and Raphia raffia palm, or jupati in Africa and America, and Borassus palmyra palmCalamus rattan palmHyphaene doum palmand Phoenix date palm in Africa and Asia.
Numbers of individuals of a species may be few or many. Centres of abundance in numbers of species occur in mixed tropical and subtropical forests in both the American and the Asian tropics. The lowland rainforests of New Guinea and the Sunda Islands and the rainforests of Central and South America are richest in palm species.
In the Gunung Mulu National Park, Malaysia, an area of rainforest spanning about 52, hectares, has species representing 20 genera. In the western part of the Antioquia region of northwestern Colombia, 89 species representing 34 genera of palms occur in an area of 19, square km 7, square miles.
It is noteworthy that palms are not the dominant elements in these forests. Large stands of single species do dominate certain types of vegetation in the tropics and subtropics.
The carnauba wax palm Copernicia alba occurs in solid stands hundreds of square kilometres in extent in the northeastern section of the Paraguayan Chaco Boreal and adjacent Bolivia and Brazil, the largest stands in this region alone containing possibly million plants.
In the eastern tropics, Nypa fruticans may form dense colonies on estuarine muds; these pure stands of nipa palm Nypa extend for hundreds of hectares in eastern Sumatra and parts of Borneo.
In other situations, dicotyledonous mangrove species occur with the nipa palm. The genus Manicaria bussu palm occupies similar habitats in some New World areas. Palms are dominant in another type of vegetation on the landward fringe of mangrove swamps in the western Malay Archipelagowhere Oncosperma tigillarium and Calamus erinaceus and, in Borneo, Daemonorops longispathus are found.
In the Amazon estuary Raphia taedigera covers extensive areas; other species of the raffia palm dominate similar habitats in West Africa. The raffia palm occurs in nearly pure stands between marsh and dicotyledonous swamp forests along the Caribbean and Pacific coasts of Costa Ricaand Mauritia flexuosa is found in vast stands in inland parts of the Amazon basin.
On riverine flats and coastal plains of Africa, Hyphaene compressa and Borassus aethiopum occur, often in great abundance. Freshwater swamplands in parts of New Guinea are dominated by Metroxylon sagu. Both the doum palm and the sago palm Metroxylon are useful, and their distribution may be due in part to human activities.
Eugeissona utilis grows in dense local stands to the exclusion of other trees in the uplands of Borneo. The vegetation dominated by Prestoea montana is distinctive in the montane forests of the Caribbean. Many of these palms are economically useful, and their natural or seminatural stands may be immensely important in local economies.
The abundance of palms may also be considered in relation to numbers of species per genus, in that a few palm genera have large numbers of species. Calamus with about is the largest and Bactris the peach palm with approximately is second.
Several other genera, Licuala, Pinanga, Chamaedorea, and Daemonorops, have more than species each.Some of the family trees have a tendency to really branch out.
But don't blame us! It's those wacky Salem citizens and all of their marrying and cheating ways that make the trees lausannecongress2018.com so bushy!

Importance of Trees as a source of oxygen and life You can understand the importance of trees by analysing the importance of oxygen.
As you know we can’t live without oxygen for 3 minutes so we need to keep planting new trees. "The Long, Long Life of Trees is a combination of personal commentary on Fiona Stafford’s love and appreciation of trees, coupled with a wealth of well-researched and fascinating examples of how trees have featured in history, art, commerce, culture and folklore.
Trees are our best friends. They play a very important role in our life. We can not live without them. They give us timber, paper and firewood. "Legend of the Dogwood" At the time of the crucifixion, the dogwood had reached the size of the mighty oak tree.
