Low prices in the sugar market in the 19th century caused severe recessions on the islands. A new cash crop, cochineal ("cochinilla"), came into cultivation during this time, saving the islands' economy. During this time
Canary Islands Several native species form laurisilva forests. As a consequence, the individual islands in the Canary archipelago tend to have distinct microclimates. Those islands such as El Hierro, La Palma and La Gomera lying to the west of the archipelago have a climate which is influenced by the moist Canary Current. They are well vegetated even at low levels and have extensive tracts of sub-tropical laurisilva forest. As one travels east toward the African coast, the influence of the current diminishes, and the islands become increasingly arid. Fuerteventura and Lanzarote, the islands which are closest to the African mainland, are effectively
