Status
The unique biodiversity of the Galápagos has been recognized and these islands are well protected as a result, being classified as a national park and a World Heritage Site. More specifically for the lava cactus, the government of Ecuador prohibits the collection of any plant in the Galápagos.
Behavior
Despite the scientific interest that the Galápagos Islands have received ever since Darwin visited in 1835, and the numerous observations of the lava cactus, the biology of this plant remains poorly known.Like all cacti, this succulent plant is capable of storing moisture in its stems when water is available, enabling it to survive periods of drought, and the spines, which are actually the leaves of the cactus, provide defense against any plant-eating animals.
Habitat
As its name suggests, the lava cactus occurs exclusively on barren lava fields, lying at sea level. Not only is it one of the few plants that survive in this extremely dry, challenging habitat, it is often one of the first plants to colonise a fresh lava flow.Predators
While the Galápagos are a protected area, and are considered one of the most unspoiled areas remaining on the planet, the fauna and flora of these islands still face major threats, such as introduced species, pressure from increasing tourist numbers, and a decline in the maintenance of protective laws. However, the lava cactus is not currently known to be facing any specific threats. It is considered vulnerable based primarily on its restricted distribution. It is listed as a vulnerable species by the International Union for Conservation of Nature.References:
