Cactus

About Cactus

• Cactus is a perennial succulent plant.
• Scientific name: Their scientific name is Cactaceae.
• Habitat: They are typically found in a wide range of different habitat in deserts, sandy coastal stretches, scrublands, dry deciduous forests, high alpine steppes and tropical rain forests.
  • While most cacti thrive in soil, some species such as leaf cactus, Rhipsalis, and Schlumbergera are epiphytes, growing on other plants, rocks, or trees.
• Distribution: They are predominantly found in arid and semi-arid regions, particularly in North and South America.
  • They are now cultivated worldwide as ornamental plants.
• Features:
  • They are known for their thick stems containing chlorophyll and areoles and unique structures that produce plant hairs, spines, bristles, flowers, branches, and leaves.
  • Most cacti lack leaves or have reduced leaves modified as spines to minimize water loss.
  • Their shallow root systems efficiently absorb moisture.
  • Their thick stems store water, while their spines protect them from grazing animals and reduce water loss.
  • Cacti vary in size and shape, from small peyote to tall saguaros.
  • While most grow in the ground, some are epiphytes that grow on other plants.
• Environmental Importance: They are ecologically adaptable and economically useful plants with significant potential in horticulture, food, livestock fodder, traditional medicine and sustainable greening of dry regions.
• Uses: They are widely grown as ornamental plants, while species such as prickly pears and chollas are cultivated for food.
  • They are also used as living fences, and their wood serves as fuel in desert regions.
  • During droughts, their spines are removed to provide fodder for livestock.
  • Certain species, such as peyote, have also been used in traditional ceremonies and medicine.
• Threats:  More than 25% of cactus species could lose over 80% of their suitable habitat by 2100 due to climate change and extreme droughts.
  • Cactus-rich regions of Chile, Peru and northeastern Brazil face particularly high risks, with some areas potentially losing over 25% of their cactus species diversity.
