Endemic cactus species of the canary islands
While the Cactus Gardens showcase species from around the world, they also play a crucial role in highlighting and preserving the unique cacti native to the Canary Islands. These endemic species have evolved in isolation, developing characteristics specifically adapted to the archipelago’s volcanic soils and microclimates.
Euphorbia canariensis: lanzarote’s iconic cactus
The Euphorbia canariensis , also known as the Canary Island Spurge, is perhaps the most recognizable endemic cactus species in Lanzarote. This imposing plant, which can grow up to 4 meters tall, is characterized by its thick, columnar stems and geometric branching pattern. Despite its cactus-like appearance, it is actually a member of the Euphorbiaceae family, demonstrating a remarkable case of convergent evolution.
In the Cactus Gardens, visitors can observe Euphorbia canariensis in various stages of growth, from young shoots to mature specimens. The gardens provide an ideal setting to study the plant’s unique adaptations, such as its ability to store water in its succulent stems and its production of a toxic, milky sap that deters herbivores.
Adaptation strategies of opuntia dillenii to arid climates
Another notable species found in the gardens is Opuntia dillenii , commonly known as the erect prickly pear. This cactus has become naturalized in the Canary Islands and serves as an excellent example of how introduced species can adapt to new environments. The Cactus Gardens provide an opportunity to observe the various adaptations that allow Opuntia dillenii to thrive in Lanzarote’s arid climate.
Visitors can examine the plant’s thick, waxy cuticle that reduces water loss, its shallow root system that efficiently captures surface moisture, and its ability to photosynthesize through its flattened stem segments (cladodes). The gardens also showcase how this species has been utilized in traditional Canarian agriculture, particularly in the cultivation of cochineal insects for dye production.
Conservation efforts for rare cactaceae in the gardens
The Cactus Gardens play a vital role in the conservation of rare and endangered cactus species, both endemic to the Canary Islands and from other parts of the world. The controlled environment of the gardens allows for the cultivation and study of species that may be threatened in their natural habitats due to factors such as habitat loss, climate change, or over-collection.
One such conservation success story is the propagation of Turbinicarpus pseudomacrochele , a critically endangered species native to Mexico. The gardens have established a breeding program for this tiny cactus, ensuring its survival and providing valuable data for conservation efforts worldwide. Visitors can learn about these initiatives through educational displays and guided tours, gaining insight into the importance of ex-situ conservation in protecting biodiversity.
Microclimates and ecosystem diversity in the gardens
The Cactus Gardens are a marvel of microclimate engineering, showcasing how careful landscaping and plant selection can create diverse ecosystems within a relatively small area. The garden’s design takes advantage of Lanzarote’s unique topography and prevailing winds to create a variety of microclimates, each supporting different assemblages of cactus species.
In the lower sections of the garden, visitors will find species adapted to more humid conditions, such as various Opuntia and Cereus species. As one ascends the terraces, the environment becomes progressively drier and more exposed, mimicking the conditions found in high-altitude desert regions. Here, tough globular cacti like Echinocactus grusonii and Ferocactus species thrive.
This gradient of microclimates not only enhances the educational value of the gardens but also demonstrates the principles of xeriscaping – landscaping that reduces or eliminates the need for supplemental irrigation. By observing how different species are arranged within the garden, visitors can gain valuable insights into sustainable gardening practices for arid regions.
