front At the RVA trees are all around us and we at the school take very special care of them because they are of great benefit to us and all the wildlife that use them.

Trees are vital for the survival of humanity. They provide us with oxygen and take in Carbon dioxide, purify the air, contribute in the water cycle, contribute in climate change, provide us with wood, food, cool down the environment, give shade and shelter, give us medicine, protect wildlife and much more. Many species are used in landscaping while at the same time performing other functions.

Mangifera indica Linnaeus (Mango) Family: Anacardiaceae

Mango is native to southern Asia, especially eastern India, Burma, and the Andaman Islands. It is a large evergreen tree 20 m tall with a dark green, umbrella-shaped crown. The trunk is stout, 90 cm in diameter; bark brown, thick, rough and scaly or furrowed.
The large leaves are leathery, 12 to 30 cm in length, and can remain on the tree for a year or more.
Flowers are produced in terminal clusters 10 to 40 cm long. Each flower is small with white petals and a mild sweet aroma.
Over 500 varieties of mangoes are known, many of which ripen in summer, some giving a double crop. The ripe fruit varies in size, shape, color, sweetness, and eating quality. They may be somewhat round, oval, or kidney-shaped, ranging from 5–25 centimetres in length and from 140 grams to 2 kilograms in weight per individual fruit. The skin is leather-like, waxy, smooth, and fragrant, with color ranging from green to yellow, yellow-orange, yellow-red, or with various shades of red, purple, pink or yellow when fully ripe.

Uses: The bark contains mangiferine and is astringent and is used against rheumatism and diphtheria in India. The resinous gum from the trunk is applied on cracks in the skin of the feet and on scabies, and is believed helpful in cases of syphilis. In some of the islands of the Caribbean, the leaf decoction is taken as a remedy for diarrhoea, fever, chest complaints, diabetes, hypertension and other ills. The wood can be converted to lumber, and is used for plywood, musical instruments, charcoal and low cost furniture.
Mangoes are widely used in cuisine. Sour, unripe mangoes are used in chutneys, pickles, side dishes, or may be eaten green with salt, and also used to make juices, ice cream, smoothies, fruit bars, and jelly.
Here when in season mangoes are preferred to other foods so in the past the term ‘pot turn down’ was common referring to the consumption of mangoes that children hardly ate pot food.

Cycas revoluta (Sago palm) Family: Cycadaceae

This very symmetrical plant supports a crown of shiny, dark green leaves on a thick shaggy trunk that is typically about 20 cm in diameter, sometimes wider.
The pith contains edible starch, and is used for making sago. Before use, the starch must be carefully washed to leach out toxins contained in the pith. Sago is extracted from the sago cycad by cutting the pith from the stem, root and seeds of the cycads, grinding the pith to a coarse flour and then washing it carefully and repeatedly to leach out the natural toxins. The starchy residue is then dried and cooked, producing a starch similar to palm sago.

Cocos nucifera L (Coconut) Family: Areaceae

Coconut is a single-stemmed, evergreen palm tree that can range in height from 2 metres up to 30 metres tall. The unbranched stem is topped by a rosette of leaves that can each be 4.5 - 6 metres long. It is one of the most useful plants for humans, providing a wide range of foods and other commodities.
The fruit consists of (from the outside to in) a thin hard skin (exocarp), a thicker layer of fibrous mesocarp (husk), the hard endocarp (shell), the white endosperm (kernel), and a large cavity filled with watery liquid (coconut water). The endosperm is soft and jellylike when immature but becomes firm with maturity.

Uses: The seed is a very versatile food, being eaten raw and used in a wide range of cooked dishes. When dry it is shredded and used in dumplings, sugar/coconut cakes and as flavouring in cakes. Oil is also made from the dried nuts that are used in cooking, as skin cream and many other beauty products.
Coconut milk or cream, which is pressed from the mix of freshly grated seed with water, has been a traditional ingredient in many African, Caribbean and especially Asian food and bakery products, and is becoming more widely known.
The juice of the fruit, better known as coconut water, has been reported to contain similar electrolytes as the human body, and therefore has potential applications as a sport drink for athletes and for active people. This has led to a rapid expansion in the demand for the product, even though desiccated coconut still remains the largest form of the product in global trade. All-natural coconut water is now being packaged and sold in various markets as a perishable beverage, although a growing number of processors are finding various ways to extend the shelf life and make the product more shelf stable.

Azadirachta indica A. Jussieu (Neem) Family: MELIACEAE

Neem trees can reach 15–30 metres in height and have attractive rounded crowns and thick furrowed bark. Leaves are 30 cm long with 9—15 lance-shaped leaflets paired except at the end; 5 –7.5 cm long to 2cm wide often curved, thin dull green above and paler below.

Uses: It is valued as a medicinal plant, as a source of organic pesticides, and for its timber. Neem is commonly used in shampoos for treating dandruff and in soaps or creams for skin conditions such as acne, psoriasis, and athlete’s foot. It is also a component in some toothpastes and mouthwashes, especially in the Indian subcontinent.
Neem leaves have long been used as a traditional treatment for diabetes, hypertension and there is some clinical evidence suggesting that it may help control blood sugar levels. Oil extracted from the seeds can be used directly as an insect and mite repellent, insecticide, and fungicide and is the source of many commercial pesticide products, including dusts, granules, and concentrates.
As a fungicide, neem oil is used to control rust, black spot, mildew, scab, anthracnose, and blight. Neem-based pesticides generally have low toxicity for mammals and are common in organic farming applications.
