Transcript of Trees
Patrick Malcolm (2006) says in his article "Origins and History of Fig Tree", origin of fig tree possibly in Norther Asia. Fig is one of the first edible plants cultivated by human since 2500BC. The fig tree has been taken to United States of America in 16th century.
Oak trees, known for their strength and endurance, have been around for over thousand years (BBC
2014). Oak trees, native to the Northern Hemisphere, can live in various forests, cool temperate climates, Mediterranean and tropical areas. (Softschools 2014).
There are more than 400 species of the willow tree most are found in the northern hemisphere. willows can either be trees or shrubs depending on the plant.
It is difficult to determine where the Pine tree originated from, given that they are so widespread and the lack of fossils. Some specimens are as old as 350 years. These trees have large round canopies, earning them the nickname "umbrella tree" and even played a role in getting New Hampshire to join the rest of the colonies in the Revolutionary war (Pearson.C 2010).
The Arecaceae, (palm tree) has stated to have originated in Mesopotamia, in saying this seeds were also found in Northern Iraq proven to be 50,000 years old confusing common researchers in the Palms origin as many sources have provided the birth of this tree is still unknown.
Having significance to the bible, Palm Tree's were used as a location marker and often treated as a celebration plant shown as a sign of victory.
Today, Palm trees have conquered the world excluding The Middle East and North Africa
Figs are among the richest plant sources of calcium and fiber and potassium which helps to stabilize blood pressure. the leaves of the fig helps with treating diabetes.
The Oak provides many uses including Medicinal, Food and hard wood furniture.
Medicinal use involves using the bark of the tree creating tea to cure sore throats.
The Oak creates Acorns commonly eaten raw.
Furniture such as tables, chairs, floors, doors, and the list goes on.
The Willow bark has great use in medicine. It contains salicin that is used to make aspirin as a remedy for fever, headache, muscle pain, menstrual cramps, gout and rheumatoid arthritis (Wong 2014).
Willow tree is also used to manufacture fishing traps, baskets, toys and furnitures.
In flooded areas, willow is often planted due to its ability to absorb large quantities of water (Softschools 2014)
Pine bark use to make timber which then make furniture, building material, fire wood etc. Also native Americans used to use pine resin for medicine. Also pine resin use to produce sealant, glue, varnish, turpentine oil and much more. (Several survival uses for pine trees - Traci J Macnamara - 2014)
Palms have a great economic importance, they are the prime source for vegetable oil and fat. Furniture can be constructed from the trunks of the Palm and the sap obtained from the flower stalk is a source of sugar,alcohol and vinegar (Moore, H.E 2013).
Figs grow well in Mediterranean climate and can be placed in most backyards. Figs do well in a sunny spot and well-drained soil. Figs are tricky to grow in very cold areas but if you put them in containers with adequate size, drainage and pruning, figs do well (Stackhouse 2014).
Fig has been bred and cultivated from early years for its commercially valuable fruit (Encyclopedia 2014).
The growth of Oak trees varies depending on the particular species, exhibiting a range of slow to rapid growth. White Oak trees produce new growth of 10-15 feet within a span of ten to twelve years, while the Pin Oak have an annual rapid growth of 18 inches. Oak's have a life expectancy surpassing 100 years (Damask, T 2010).
The Weeping Willow is one of the most fast growing trees, With Growth starting from cuttings of another Willow tree.
By inserting the cut end into moist soil with lots of drainage The Willow will begin it's growth journey. The Willow takes about a year to be 10 inches round and a staggering 11 inches tall,
reaching the average height of 40 feet tall.
The average yearly growth of a pine tree is less than one foot to more that two feet but there is three grouped types of pine and depending on the type it may grow faster, slower or medium. the slow pine grows one foot, the medium grows one to two feet and the faster one grows two feet.
Palm trees can be seen in tropical and Mediterranean areas. Normally palm trees doesn't have branches but it has bunch of leaves called as a "crown". The main factors affecting to the growth of a palm tree are species, location and climate. Palm tree doesn't require a special care for its growth (Bergman Phil, 2014)
In summary, trees are important to man's existence in this world. These days having an awareness on the many aspects of trees especially their benefits has become a critical factor for the conservation of trees. The group's common interest in trees and commitment to search credible and reliable sources via the checklist have inspired the team to produce this online content that encourages preservation of trees.
The Fig also known as Ficus Tress expands due to birds and insects that feed off the fruit produced, Ficus incurs its growth and living to mammals and birds that scatter the seeds from one place to another.
The Fig plays host to impregnated female wasps for a short time waiting for fertilization from male wasps.
Normally Oak prefer to grow in a loamy well drained soil. So the roots are three times longer as height of an oak tree. There are wide variety of habitats living with oak tree, especially some are along its roots. Oak tree increases the ground water and prevent surface erosion.
A single Willow tree supports hundreds of organisms and species, playing an important role in pollination when few flowers are available. The willow provides wild life with a haven in which to migrate and the root systems create natural sturdy nets in the soil which delay ecological erosion (Edgar, T 2013)
Pine trees have maintained their population better than others because the trees are adaptable to cold and dry climates. They are the largest and most important family of the conifers, producing naval stores, paper pulp, lumber, drying and non-drying oils. In some areas in the United States population of pine trees has decreased due to over cutting (Encyclopedia 2014).
Palms have adapted to many habitats within their geographic limits. they tend to be associated with the jungle or tropical shores where the coconut is a prominent feature. the palm tree in the forest thrives on well drained acid soil.
The dense thicket of the Fig tree (Ficus Carica) can significantly alter the habitat by excluding and reducing the growth of other Flora. The fruits of the tree are considered a food source to pests, such as foxes. Triterpenoids contained within the leaves have been shown to cause persistent irritation ( Department of Environmental and Primary Industries 2014).
Oak trees are not very palatable and harmful to livestock particularly horses, cattle and sheep. Leaves, twigs and acorns of oak contain tannins that are toxic if eaten in large quantities. Black and red oak are more toxic than white oak. Clinical signs of toxicity include colic, constipation and/or diarrhea and frequent urination(Marteniuk 2008).
According to the studies done by Canadian Bluestem Nursery (2014), the roots of willow tree growing fast and spreading to find water and it absorbs underground water heavily. Also the roots can damage to buildings and, especially drainage lines. Also it spreads seeds heavily in to the environment which results to more plants. Also it makes messy environment as it drops catkins and leaves in spring and autumn respectively.
CCA Treated Pine (arsenic) contains Copper, Chromium, Arsenic meaning it can be poisonous and harmful if exposed to in large amounts.
It is mentioned that children's play equipment contains treated pine (D.O.H 2009) but, following basic hygiene requirements after play will not pose any harm to children.
In saying this the APMVA denies any unsafe allegations toward the use of this product without any sufficient evidence.
Palm trees are prohibited to entry into USA from all countries because of disease and insects that can pose a significant threat to the USA's ornamental palm industry. Rich Magargal, a certified tree safety professional identified electrocution, falls and suffocation are the main causes for palm tree accidents and 21% among tree deaths occurred in palm trees since 1990.

Since the beginning, trees have provided us with two of life’s essentials, oxygen and food. The importance of trees is often overlooked, and deforestation is having an impact on us. This presentation covers the history, uses, growth, ecology and risks of trees; in particular, Oak, Fig, Willow, Palm and Pine. With the aim of producing a lively, informative compilation displaying the many aspects of trees via collaborative work, we have derived information from credible online sources using the 'five checklist: accuracy, authority, objectivity, currency and coverage' (Metzger, M 2007). We hope to stimulate an interest in trees; which, in turn encourages appreciation and conservation awareness.
