In the process of development, many lands in the islands were converted to agricultural fields and several hundred varieties ofherbaceous plant and tree species were introduced, resulting in depletion of the original vegetation. However, efforts are now underway at reforestation to improve the wildlife of Cape Verde, with reported planting of three million new trees every year (about 7000 per day), withpine,oak,sweet chestnut andacacia as the prominent varieties being planted.[1][2] Cape Verde is also one of the world's top tencoral reefBiodiversity hotspots.[3]
Historically, Cape Verde was probably not rich with greenery, although the evidence of the situation in earlier times is severely lacking.[4] When Cape Verde was first discovered and colonized by thePortuguese in the 15th century, the wildlife consisted mainly of dry forests and scrub habitat, which underwent a sea change under the influence of the inhabitants of this then isolated and uninhabited group of islands. The endemic flora and fauna of the islands were disturbed and have now remained confined mostly in the mountain peaks, steep slopes and other inaccessible areas.[4]Vegetation in the islands is basically of the savannah or steppe type. There are trees typical of both temperate and tropical climates, depending on elevation. The flatter parts of the islands sustain semi-desert plants while the higher lands have arid shrubland.[4] The leeward slopes tend to contain desert, with a very sparse shrub cover, mostly thorny or toxic.[5] A number ofxerophilous plants grow in the brackish subsoil of Maio, Sal, and Boa Vista.[5]
There are 664 listed plant species, which include two threatened species.[6] Over 80 vascular plant taxa are reported to be endemic to Cape Verde; these includeTornabenea,Aeonium gorgoneum,Campanula bravensis (bellflower),Asteriscus smithii (Nauplius smithii),Artemisia gorgonum (sagebrush),Sideroxylon marginatum,Lotus jacobaeus,Lavandula rotundifolia,Cynanchum daltonii,Euphorbia tuckeyana,Polycarpaea gayi andErysimum caboverdeanum (wallflower).[3] Several trees are indigenous such as the blue-green flat-topped dragon treeDracaena draco,Tamarix senegalensis,Phoenix atlantica (tamateira), in the lagoons and deserts ofBoavista, theironwood tree and a species offig tree andProsopis juliflora which locally is simply called "acácia"[4]). As a result of extensive tree planting since 1975, there arepine trees,oaks andsweet chestnuts on the cool peaks ofSanto Antao,eucalyptus on the heights of Fogo, multipleneem trees in São Vicente and forests of acacia on Maio.[5]
Here is a list of endangered flora in Cape Verde, of which 97 are ranked species and 19 are ranked subspecies. They belong to 62 genera and 28 families. Of which 50 of them are in the island ofSanto Antão, 45 inSão Nicolau, 38 inSantiago and 37 inFogo. 80% of them are in the highlands.[7]
