Location
The island is located about 90 kilometres east of the Spanish mainland. The distance San Antonio - Dénia is 111 km, Ibiza - Denia 146 km, Ibiza - Palma de Mallorca 154 km. The distance to Alicante is about 200 km, San Antonio - Valencia 150 km, Ibiza - Barcelona 264 km and to Algiers 276 km.
Geology
The Balearic Islands are the blasted continuation of the Andalusian rocky mountains that stretch from Gibraltar across the Sierra Nevada. A trench about 1,500 meters deep separates the islands from the Spanish mainland. The Pitiusas have their own continental shelf.
Description
Ibiza is an inland hilly island with a rugged coastline punctuated by sandy calas. The length of the coast is about 210 kilometres. Ibiza's highest elevation is Sa Talaia at 476 msnm.
The biodiversity and culture of Ibiza was declared a World Heritage Site in 1999.
fauna and flora
Apart from the many well-known beaches and coves, the island of Ibiza has an almost completely unknown wealth of fauna and flora.
The island can be roughly divided into four landscape zones: The north or steep coast, forests and garigue, cultivated land and farmland, beaches and bays.
The north coast, es amunts, the hills, are largely protected. The area stretches from the plateau at Santa Agnès de Corona to the north-eastern tip of the island to Punta Grossa near Cala San Vicente. This region is sparsely populated, there are hardly any towns and only a few accessible bays or beaches and therefore almost no tourism.
In the vast evergreen pine forests and in the garigue, these landscapes often interspersed with juniper bushes, rosemary, thyme and other wild herbs, also grow, among others, the rare holm oak, autochthonous orchids and wild gladioli. It is also the retreat of the genet, which has become very rare.
On the coasts, beaches and coves, and in the wetlands such as Ses Salines, the water basins for salt extraction, and Ses Feixes, the two allotment zones around the town of Ibiza, probably created by the Moors in the 11th century, which are part of the Unesco World Natural Heritage, grow plants that are particularly resistant to salt water. These wetlands are also the breeding grounds of numerous aquatic birds. A colony of flamingos now lives year-round in the old salt ponds of Ses Salines. Kestrels (more rarely Eleonora's falcons), ospreys and many other species of birds such as gulls (laughing gulls, herring gulls, storm-petrels and more rarely the coral gull). Swallows, herons (night heron, great egret, little egret), cormorants and black-winged stilts also live in these zones.
The cultivated and agricultural land of the island of Ibiza is characterised mainly by a form of three-field farming known since the Middle Ages. These fields are usually planted with wheat (trigo), barley (cebada) or oats (avena). Typically, almond, olive, carob and fig trees were cultivated at loose intervals in between. The edges of the fields, often terraced and traditionally enclosed with dry stone walls, are planted with wild plants and vines for farm wine (vi payes). Corn poppies, margarites (Chrysanthemum coronarium), sharp sheaves, wild fennel (Foeniculum vulgare) and wild asparagus or rock roses. Kites, barn owls and lesser scops owls or hoopoes live here. Also goldfinches, finches, thrushes, velvet-headed warblers or tits, curlews and turtle doves.
In areas with groundwater resources or deep wells, such as near San Antonio, fruits and vegetables are planted. Here especially melons, tomatoes, grapes, citrus fruits, but also legumes such as beans, lentils or peas. In the area around Santa Gertrudis, which is considered as fertile as the great plain in front of San Miguel, fruit trees grow with cherries, peaches, apricots, mangos or avocados. The valley of San Mateo is known for its viticulture. In addition to the dog breed Podenco Ibicenco (Ca Eivissenc in Catalan), the most conspicuous animal on the island, Ibiza has a number of other autochthonous animals. For example, the peasant chicken Pollo payes, the Oveja ibicenca, the Ibizan sheep, a wild rabbit and the Pityus lizard (Podarcis pityusensis pityusensis).
Threat to fauna and flora
Unknown until a few years ago were any kind of snakes or other poisonous animals. Only in the course of the import of olive trees for squares and gardens, vipers (horseshoe snakes and step snakes) were introduced, which are now spreading but are also already hunted by the island government, because they decimate small game and here especially rabbits and lizards and bird clutches.
Since around 2005, palm trees, mostly the Canary Island date palm, have been decimated by the palm weevil on Ibiza. Although the island government insists that plants infested by the insect are immediately sprayed with insecticides or destroyed, the infestation continues to spread. Meanwhile, other plants such as fan palm, dwarf palm and palm lilies are also being infested. The damaged palms slowly die from the core. This is visible when the fresh palm fronds in the centre of the palm turn brown and droop.
Since 2016/17, the fire bacterium has been discovered in the Balearic Islands, especially in Mallorca, but also in Menorca and Ibiza. This bacterium also attacks fruit trees such as olive and almond trees or vines. The external characteristic is the partial withering of the plant. Since there is no suitable antidote so far, the EU obliges as an immediate measure to cut down and burn all trees and all others within a radius of 100 meters from the infested plant. Investigations of the bacterium have shown that it is the aggressive form Xylella fastidiosa pauca, which, in addition to the trees already mentioned above, can also infect cherry trees, laurel bushes, willow-leaf acacias, lavender, rosemary, oleander, Australian rosemary (Westringia fruticosa) and crucifers.
Another threat to the island's flora is the large forest gardener (Tomicus piniperda and Tomicus destruens), which has become more common in recent years. Thus, one is surprised to suddenly find completely brown, withered pine trees in a patch of forest. This is a beetle from the bark beetle family, which attaches itself to the trunk of the pine tree and deposits its brood in the bark, this leads to the death of the tree in a short time.
The processionary moth plague, which is widespread throughout the Balearic Islands, has been relatively well contained in Ibiza in recent years. For many years, the spread of the moth has been reduced and prevented in various regions of the island through the use of pheromones. This can be recognised by the white plastic cups with the pheromone that are fixed in the pine trees. In the meantime, Bacillus thuringiensis is also used for control.
A new occurrence around 2019/20 is also the infestation of cacti (Opuntia ficus-indica) by the cochineal scale insect. The shrub-like formations of the plant are covered with white spots and after some time the rotten leaves fall off. However, after a time the plant can regenerate itself.
The Picudo negro appeared for the first time in 2019/20. A black beetle from the Rhynchophorus family that threatens the agaves. The beetle bores into the heart of the agave and lays its eggs there. The maggots feed on the soft plant parts inside the plant. Apparently, another bacteria is released in the process. The plant dies completely in a short time. The beetle also attacks yuccas and dragon trees.
Climate
Ibiza has the most balanced climate of the Balearic Islands. Average temperatures are around 26°C in summer and reach a very mild 12°C in winter.
