Geographically, ferns are most abundant in the tropics. Arctic and Antarctic regions possess few species. On the other hand, a small tropical country such as Costa Rica may have more than 900 species of ferns—about twice as many as are found in all of North America north of Mexico.

Where do ferns typically live?
They are commonly found in wet climates, with about 70 percent of species living in tropical regions, and most of the rest in temperate zones—although a hardy few actually live in the desert or the Arctic. Ferns come in a wide variety of shapes, textures, colors, and sizes.
Where do ferns grow naturally in the US?
There are approximately 380 species of ferns in North America. Most of them can be found on the national forests and grasslands.
Do ferns grow everywhere?
Nowadays, ferns can be found in almost any part of the world. Anywhere you go, you can find them growing, and if you cannot, it means that you are not exploring enough. Ferns can be found in remote mountain elevations, in the forest, driest deserts, water bodies, and even open fields.
Are ferns a tree?
Tree ferns are true ferns. ... A tree fern's unusual trunk consists of a thin stem surrounded by thick, fibrous roots. The fronds on many tree ferns remain green throughout the year. In a few species, they turn brown and hang around the top of the trunk, much like palm tree leaves.
Do ferns still exist today?
Ferns dominated the botanical world for hundreds of millions of years, between the Devonian, about 360m years ago, and the rise, about 120m years ago in the Cretaceous, of the flowering plants familiar today. ... Almost all ferns now alive are its descendants.
Where can I find wild ferns?
Ferns are found naturally in damp forests in tropical or temperate zones. Some ferns grow on rocks, while others grow on soil and water. Some fern species grow in the open, and these varieties can tolerate sunlight well.
Which state has the most ferns?
Florida is one of the most plant-species-rich regions in the United States, with more than 4700 native and naturalized species of plants (Wunderlin et al., 2017). The state has the highest fern diversity in the continental United States (Nelson, 2000), with ca.
Are ferns edible?
Most ferns make fronds that look like the edible fiddlehead, but not all ferns are edible. It is vitally important to make a correct identification when harvesting. Some ferns are poisonous, including the ubiquitous Bracken Fern (Pteridium aquilinum). Each region has its own preferred species for fiddlehead harvest.
Is fern An ancient?
Ferns are ancient plants whose ancestors first appeared on Earth over 300 million years ago. Members of a division of primitive plants called Pteridophytes, ferns are one of the earth's oldest plant groups and dominated the land before the rise of flowering plants.
Do ferns have fruit?
Shared conifer and fern characteristics include the fact that neither produce flowers. ... Ferns are seedless vascular plants. Generally, they reproduce via spores (instead of seeds), which are produced on the bottom of fern fronds by specialized structures called sporangia.
Where do ferns produce spores?
The fern life cycle
Mature plants produce spores on the underside of the leaves. When these germinate they grow into small heart-shaped plants known as prothalli. Male and female cells are produced on these plants and after fertilisation occurs the adult fern begins to develop.
Where are ferns found in Australia?
AUSTRALIAN INDIGENOUS FERNS
They are found in a variety of situations such as tropical rainforests (often growing as epiphytes on trees and rocks), in gullies in cool southern forests, in sub alpine areas, in exposed coastal areas and tropical mangrove swamps, and in crevices in rocky outcrops in dry inland areas.
What is special about ferns?
Ferns are unique in land plants in having two separate living structures, so the ferny plant that we see out in the bush produces spores, and those spores, when they are released, don't grow straight back into a new ferny plant. They grow into a little tiny plant that we call a gametophyte.
What is the oldest fern?
Fossils of Osmunda cinnamomea, cinnamon fern, were found in 70 million year old rocks! This discovery was published about 10 years ago, and no differences could be found between the fossil and the fern as it is today.
Are ferns extinct?
Ferns are one of the oldest groups of plants on Earth, with a fossil record dating back to the middle Devonian (383-393 million years ago) (Taylor, Taylor, and Krings, 2009). ... However, despite the venerable age of the group as a whole, most of the earliest ferns have since gone extinct.
Are ferns forbs?
Herbaceous plants ("herbs") are vascular plants without significant woody tissue above or at the ground and include flowering plants, ferns, horsetails, lycopods, and whisk-ferns. Forbs are non-graminoid (grasses, sedges, rushes, etc.) ...
Are ferns plants or fungi?
A: The growths on your fern are not from a fungus. They are fern spore cases and are not harmful to the plant. Unlike flowering plants, ferns reproduce by spores rather than seed. Spore cases (sporangia) are produced on the bottom side of the fronds; each case contains numerous spores.
