sometimes present on the back; ventral surface always whitish. Found in localities where fresh water is present, whether flowing or stagnant. Prefers shallow pools in valleys, and water reservoirs, where it rests in the water leaving the head above the surface. In summer it lies concealed in damp places. Lays around 500 eggs in a layer held together by a gelatinous covering. Egg-mass often becomes attached to vegetation, stones or the sides or bottom of the pool. Each egg grows to a diameter of about 4mm before hatching. Young (tadpoles) have a long tail and do not resemble adult. Tadpoles spend 5-8 weeks in the water, breathing through gills. In time, lungs develop, enabling them to breathe air. Hind legs develop before forelegs. Tail shortens and eventually disappears. Diet also changes gradually from vegetable matter to insects and other small animals. Common. Reptile:

The Maltese Wall Lizard ( GREMXULA TA' MALTA) is about twenty eight centimetres and consists of four subspecies. Maltensis found on the islands of Malta, Gozo and Comino is generally greenish and often speckled. Filfolensis is found on Filfla and is blackish with blue or pale blue spots, it is the largest of the four races. Kieselbachi found on Selmunett islands varies in colour from brown to grey with small black spots and a yellow belly. Generalensis found on Fungus Rock is coloured reddish below with bluish flanks. Lizards feed mostly on insects, but also on fruit and vegetatble matter. When cornered by a predator, as a last resort they shed their tail. This is possible due to an anatomical arrangement whereas by the use of certain muscles a special bone breaks. Blood vessels are immediately closed by spasms and the tail falls off writhing vigorously for a few minutes. Whilst the predators attention is so occupied the lizard tries to escape. This tactic however is costly in energy requirements since it entails the loss of a store and the necessity of growing a new tail. In rare circumstances the tail is only partially broken off and a new one grows. The end result is a two tailed lizard. This is possible in all the races. Females and young lack the bright colours of the males, and are generally brownish. Male shows territorial behaviour, claiming a small patch of land and threatening other approaching males. During their threat display, the males puff themselves up, tremble and raise their heads to display the bright colours below the neck. When a female approaches, the male makes similar movements, which now serve to attract the female for eventual mating. This takes place in Spring, soon followed by the laying of 1-2 eggs in the soil or under a stone. Eggs normally hatch between June and Mid -August. Endemic to Malta and the islands of Linosa and Lampione, where a fifth subspecies occurs. A separate race probably exists on Kemmunett. Very common.

Female leaves the trees in order to lay eggs in a hole dug near the base of the trunk; the eggs are then covered with soil. Adapted for life in wooded areas, but often seen in garigue habitats. Was introduced in the 19th century by protestant missionaries who used to bring specimens over from North Africa, then released in the gardens of what was later to become the Jesuit college of St Ignatius in St Julians. Has since spread to all parts of the island of Malta. Also occurs on Gozo. Frequent. Trees:

Carob

Ceratonia siliqua

Carob is a species that has a long history of use by humans. Other names commonly used for Carob are St John's Bread and Locust. Legend has it that St John ate the pods of this species and hence the name. Evidence of the use of Carob products by humans date back to ancient Greece and Egypt where the plant was used as a source of food. The seeds from the Carob tree are extremely consistant in size and weight and are believed to have been the original guage for the 'carat' used by jewellers. The species itself is ancient having survived the last ice age and flourished throughout the Mediterranean region since. It is well adapted to

harsh climates and poor soils. Throughout its natural range the species has been widely cultivated because of its reliability as a food and fuel resource even during times of drought. Description: The carob tree is a slow growing, medium sized evergreen tree originating in the eastern Mediterranean. It is a member of the Legume (Pea) family and is the only member of the genus Ceratonia. It is a xerophilous scleophphyllous species well suited to dry infertile environments. The species is trioecious with male, female and hermaphrodite inflorescences and is often multi stemmed growing up to 15 meters in height. The production of fruit begins around the age of 15 and continues for the life of the plant. The leaves are broad, dark green and offering substantial shade. The pods are long and leathery often growing up to 300mm long.

another. Their skin is rich in tannin, giving the mature leaf its gray-green appearance. The leaves are replaced every two or three years, leaf-fall usually occurring at the same time new growth appears in the spring. Flowers: The small, fragrant, cream-colored olive flowers are largely hidden by the evergreen leaves and grow on a long stem arising from the leaf axils. The olive produces two kinds of flowers: a perfect flower containing both male and female parts, and a staminate flower with stamens only. The flowers are largely wind pollinated with most olive varieties being self-pollinating, although fruit set is usually improved by cross pollination with other varieties. There are

self-incompatible varieties that do not set fruit without other varieties nearby, and there are varieties that

are incompatible with certain others.

Incompatibility can also occur for environmental reasons such as high temperatures. Fruit: The olive fruit is a green drupe, becoming generally blackish-purple when fully ripe. A few varieties are green when ripe and some turn a shade of copper brown. The cultivars vary considerably in size, shape, oil-content and flavour. The shapes range from almost round to oval or elongated with pointed ends. The trees reach bearing age in about 4 years.

Pinus halepensis

The Aleppo Pine (Pinus halepensis) is a pine native to the Mediterranean region.

P. halepensis cones It is a small to medium-size tree, reaching 15-25 m tall and with a trunk diameter of up to 60 cm, exceptionally 1 m. The bark is orange-red, thick and deeply fissured at the base of the trunk, and thin and flaky in the upper crown. The leaves ('needles') are in pairs, very slender, mostly 6-10 cm long, and distinctly yellowish green. The cones are narrow conic, 5-10 cm long and 2-3 cm broad at the base when closed, green at first, ripening glossy red-brown when 24 months old. They open slowly over the next few years, or after being heated by a forest fire, to release the seeds, opening to 5-8 cm broad. The seeds are 5-6 mm long, with a 20 mm wing, and are wind-dispersed.

Evergreen Oak

Quercus ilex

Evergreen Oak, is a large evergreen oak native to the Mediterranean region. It is a member of the white oak section of the genus, with acorns that mature in a single summer. It is a medium-size tree to 20-27 m tall with finely square-fissured blackish bark and leathery evergreen leaves. The old leaves fall 1-2 years after new leaves emerge. The leaves are dark green above, and pale whitish-grey with dense short hairs below. The leaf shape is variable, the adult leaves are entire, 4-8 cm long and 1-3 cm broad, while those on the lower branches of young trees are often larger (to 10 cm long), and are toothed or somewhat spiny. This is presumed to be for protection from grazing animals. The name ilex is originally the classical Latin name for the Holm Oak, but was later also used as a botanical genus name for the hollies. The flowers are catkins, produced in the spring; the fruit is an acorn, which matures in about 6 months. Trees:

covering 50 ft (15 m) of ground, but in permeable soil some of the roots may descend to 20 ft (6 m). The deciduous leaves are palmate, deeply divided into 3 to 7 main lobes, these more shallowly lobed and irregularly toothed on the margins. The blade is up to 10 in (25 cm) in length and width, fairly thick, rough on the upper surface, softly hairy on the underside. What is commonly accepted as a "fruit" is technically a synconium, that is, a fleshy, hollow receptacle with a small opening at the apex partly closed by small scales. It may be obovoid, turbinate, or pear-shaped, 1 to 4 in (2.5-10 cm) long, and varies in colour from yellowish-green to coppery, bronze, or dark-purple. Tiny flowers are massed on the inside wall. In the case of the common fig discussed here, the flowers are all female and need no pollination. There are 3 other types, the ''Caprifig'' which has male and female flowers requiring visits by a tiny wasp, Blastophaga grossorum; the "Smyrna" fig, needing crosspollination by Caprifigs in order to develop normally; and the "San Pedro" fig which is intermediate, its first crop independent like the common fig, its second crop dependent on pollination. The skin of the fig is thin and tender, the fleshy wall is whitish, pale-yellow, or amber, or more or less pink, rose, red or purple; juicy and sweet when ripe, gummy with latex when unripe. Seeds may be large, medium, small or minute and range in number from 30 to 1,600 per fruit.

Although, like its relative, it is found near habitation, it more often breeds in trees. It builds a closed nest. 4-8 eggs are laid. The male is similar to the House Sparrow, but has a chestnut cap, blacker back, and underparts heavily streaked with black. The female is effectively inseparable from its relative. It sometimes hybridizes with House Sparrows. This species feeds principally on seeds, like other sparrows.

eTwinning Project – The International Year of Forests

its small size. The distinctive red patch on the chest of both sexes led to its original name of redbreast. Robins have a fluting, warbling song in the breeding season. Robins often sing into the evening, and sometimes into the night. Both males and females sing during the winter, when they hold separate territories, the song then sounding more plaintive than the summer version. The female Robins move a short distance from the summer nesting territory to a nearby territory that is more suitable for winter feeding. Male Robins keep the same territory throughout the year. Robins build a neat cup nest in crevices, holes or artificial sites such as discarded kettles. When juvenile birds fly from the nests thay are all brown in colour and do not have a red breast. After 2 to 3 months out of the nest, the juvenile birds grow some reddish feathers under their chins and over a further 2 to 3 months this patch gradually extends to complete the adult appearance. Male Robins are noted for their highly aggressive territorial behaviour. They will ruthlessly attack other males that stray into their territories, and have been observed attacking other small birds without apparent provocation. Such attacks sometimes lead to fatalities, an aspect of the birds' behaviour which is at odds with its wholesome, gentle public image. Insects:

pair of transparent wings. The house fly can taste using its its feet and with its mouthparts. Adults are about 6 - 12.5 mm long with 13 - 15 mm wingspan. House flies are dark gray, with four dark stripes down the top of the thorax. They have sponging mouthparts (they cannot bite); house flies can only eat liquids, but they can liquefy many solid foods with their saliva. Reproduction: The complete life-cycle of a house fly takes from 10 to 21 days. On the average, 12 generations of house flies can be produced in one year. Adult females lay 120-150 tiny white eggs, usually in manure or other warm, moist, decaying organic matter. A female lives for about 2 1/2 months and can lay up to 1,000 eggs in her short life. The eggs are only about 0.04 inch (1 mm) long and hatch into white, worm-like maggots in about 12 hours. The maggots grow to be about 12.5 mm long. When they are this big, they burrow into the ground to pupate. An adult will emerge in about 5 to 6 days (in warm weather) or about a month (in cold weather).
