Centaurea horrida | |
Centaurea horrida is a species of the genus Centaurea which is only found growing in Sardinia and associated islands. [2] [3] Due to their limited ability to disperse, they are isolated from other environments, and have a very low colonizing ability. [3]
It is a parent of the hybrid C. × forsythiana. [1]
In 1992, C. horrida was designated as a 'priority species' under Annex II of the Habitats Directive of the European Community (which was reformed as the European Union the following year). This designation was meant to serve as the basis for Italy to declare which areas in which it occurs are 'Special Areas of Conservation' -which were to form the backbone of the Natura 2000 network, but only if these areas include one of the number of habitats listed in Annex I of the directive.

Abies nebrodensis, the Sicilian fir, is a fir native to the Madonie mountains in northern Sicily.
Aiphanes is a genus of spiny palms which is native to tropical regions of South and Central America and the Caribbean. There are about 26 species in the genus, ranging in size from understorey shrubs with subterranean stems to subcanopy trees as tall as 20 metres (66 ft). Most have pinnately compound leaves ; one species has entire leaves. Stems, leaves and sometimes even the fruit are covered with spines. Plants flower repeatedly over the course of their lifespan and have separate male and female flowers, although these are borne together on the same inflorescence. Although records of pollinators are limited, most species appear to be pollinated by insects. The fruit are eaten by several birds and mammals, including at least two species of amazon parrots.
Centaurea calcitrapa is a species of flowering plant known by several common names, including red star-thistle and purple star thistle. It is native to Europe but is rarely found there, it is known across the globe as an introduced species and often a noxious weed.

The Habitats Directive is a directive adopted by the European Community in 1992 as a response to the Berne Convention. The European Community was reformed as the European Union the following year, but the directive is still recognised.
A Site of Community Importance (SCI) is defined in the European Commission Habitats Directive (92/43/EEC) as a site which, in the biogeographical region or regions to which it belongs, contributes significantly to the maintenance or restoration at a favourable conservation status of a natural habitat type or of a species and may also contribute significantly to the coherence of Natura 2000, and/or contributes significantly to the maintenance of biological diversity within the biogeographic region or regions concerned.
Anthemis glaberrima is a species of flowering plant in the family Asteraceae. It is found only in Greece. Its natural habitats are rocky shores and Mediterranean-type shrubby vegetation.
Centaurea gymnocarpa, also known as Capraian cornflower or centaury of Capraia, is a species of flowering plant in the family Asteraceae. It is a rare species endemic to Italy found only on Capraia, a small island located in the Tuscan Archipelago, with the species being distributed across 8 subpopulations on the island's surface.

It is considered an endangered species. In 1992 it was designated as a 'priority species' under Annex II of the Habitats Directive in the European Union, which means areas in which it occurs can be declared Special Areas of Conservation, if these areas belong to one of the number of habitats listed in Annex I of the directive.
Centaurea alba is a species of Centaurea found in the Iberian Peninsula in southern and central Spain and in a small neighbouring area in the interior of Portugal. There are three recognised subspecies, and of one subspecies, the nominate, there are furthermore three varieties.
Iris revoluta is a plant species in the genus Iris, it is also in the subgenus Iris. It is a rhizomatous perennial, from a small area in Salento, Italy.

The biogeographic regions of Europe are biogeographic regions defined by the European Environment Agency. They were initially limited to the European Union member states, but later extended to cover all of Europe west of the Urals, including all of Turkey. The map of biogeographic regions is deliberately simplified and ignores local anomalies. It is intended primarily as a framework for coordinating and reporting overall results of conservation efforts.
