General Information About Paulownia Trees And Other Trees In General

By Harriett Crosby


Paulownia trees are among the oldest and finest trees around the world. The word tree has many definitions. Under botany a tree is defined as a perennial plant with branches, supporting leaves, and trunk. Under some situations the definition is restricted to plants of predestined height or woody plants. Bamboo, palms, bananas, and ferns are normally included in wider definition of trees.

Different plants have different lifespan some live for several years whereas some are seasonal. They develop to different heights. The current tallest tree is approximated to be 115.6 meters equivalent to 379 feet. It is believed that plants may only grow up to 426 feet equivalent to 130 meters. Vegetation is amongst the first living things to have occupied the Earth. They are estimated to have occupied the Earth some 370 million years back.

Vegetation has undergone evolution in response to changing environmental conditions and factors like competition. They had to grow tall as part of evolutionary adaptation. They grow tall due to competition for space and sunlight. Tall plants access sunlight enabling them to photosynthesize as opposed to short ones. The short plants have modified structures to ensure their survival. They coil around taller vegetation for support and to access sunlight.

Plants grow in large numbers in tropical regions. The tropical has all the necessary growth conditions for plants including fertile soils, sufficient sunlight, and adequate rainfall. The ranges and diversity of plants is not clear because various species grow in different regions under varied environmental conditions. Botanists are still surveying and collecting data on various species.

A normal tree comprises of many parts such as stem, branches, leaves, and roots. Every part has a unique role that it serves. The trunks or stems support branches. Roots are for support besides absorption of mineral ions from the ground. Leaves make food using sunlight, which is necessary for development of plants.

Plants play a great part in controlling pollution, moderating the climate, and reducing erosion. They clean excess carbon dioxide from the environment through carbon cycle. They maintain and hold soil strongly around roots thus minimizing erosion on soil. They are a rich source of fruits and home to birds. They are utilized as medicine in therapy of many illnesses. Some function as worship places and shrines for various communities.

Plants are presently under threat as a result of human activities. Cultivators are cutting down trees when they open up land for cultivation. Plants are of great importance to both the surroundings and humans. The need to preserve vegetation led to creation of universal organizations whose responsibility is to encourage and teach people to plant more plants. The world environment day is observed as a reminder to people to conserve the environment.

Paulownia trees are grown under the best conditions to increase chances of survival and growth in all types of climate. The tree nurseries in this region are tended to by the best agriculturalists. Professionals in this area conduct enough research to ensure they can adequately deal with all diseases affecting plants. They can be contacted through their websites on the internet.
