Cycads are found in a range of habitats including tropical forests, seasonally dry forests and savannas. One species of the African cycads, genus Encephalartos, has evolved to withstand the stress of living in desert environments. Typically, cycad plants are most successful in habitats with well-drained soils.

Where did the Cycadophyta live?
The living cycads are found across much of the subtropical and tropical parts of the world. The greatest diversity occurs in South and Central America.
Where can you find cycad?
Cycads and palms are found in tropical and subtropical parts of North America, South America, Central America and the Caribbean, Asia, Africa and Oceania. They occur in a range of habitats, from closed canopy tropical forests to open grasslands and desert-like scrublands.
What are some examples of Cycadophyta?
There are many Australian native cycads and three endemic genera: Bowenia, Lepidozamia and Macrozamia. Although they are very popular garden plants, cycads are threatened, endangered or extinct in the wild. Cycads thrive in tropical and subtropical areas with moderate to high rainfall.
What type of wood is found in Cycadophyta?
Parenchymatous medullary rays separate the individual bundles. Tracheids and parenchyma are made of xylem. Vessels from Xylem are absent.
Where do fern plants grow?
Ecologically, the ferns are most commonly plants of shaded damp forests of both temperate and tropical zones. Some fern species grow equally well on soil and upon rocks; others are confined strictly to rocky habitats, where they occur in fissures and crevices of cliff faces, boulders, and taluses.
Why are cycads so expensive?
Because of their rarity and attractiveness as garden elements, cycads have great commercial value, particularly for “bragging rights”.
Is a palm tree a cycad?
People often confuse cycads as palms due to their similar overall appearance. But they are completely different, and they belong to two separate plant groups. The key difference between cycads and palms is that the cycads are nonflowering plants (gymnosperms) while the palms are flowering plants (angiosperms).
How many cycads are left?
Cycads are the oldest living species of seed plants in the world. They date back 340 million years and have survived three mass extinctions. There are 347 species of cycad left today and while many thrive in areas that are free from development, cycads are one of the most threatened families of plant in the world.
Can you eat cycad fruit?
The Aboriginal People had developed methods of removing the toxins that allowed the cycad seeds to become a rich food source. Different groups had different methods of removing the toxins, but they all achieved the sand end, an edible, sustaining, fruit.
How old is a cycad?
The oldest cycad fossils are 245 to 208 million years old, from the Triassic period. The first cycads are believed to have appeared in the Permian period 270 million years ago.
What is an Australian cycad?
Macrozamia communis is an Australian cycad found on the east coast of New South Wales. The common name for the species is burrawang, a word derived from the Daruk Australian Aboriginal language; this name is also often applied to other species of Macrozamia.
