Behavior

The Man Fern, also known as the soft tree fern, is a slow-growing ancient species that adds a prehistoric feel to any environment. Growing at a rate of only 3.5 to 5 centimeters per year, these long-lived giants can survive for centuries. Unlike many plants, they are particularly resilient to being moved; because the trunk is essentially a mass of aerial roots, they can survive being cut at the base and replanted if kept sufficiently moist.

In the wild, the Man Fern plays a vital role in its ecosystem. Its fibrous trunk acts as a host for many other organisms, including mosses, liverworts, and smaller epiphytic ferns that grow directly on its 'bark.' For backyard enthusiasts, this fern provides essential shade and high-humidity microclimates that attract a variety of moisture-loving insects and amphibians.

Camera Tips

Capturing the beauty of a Man Fern on a trail camera requires a different approach than filming moving wildlife. The most rewarding project is a long-term time-lapse of the 'fiddleheads' uncurling. Set your camera to a time-lapse mode, taking one photo every 4 to 6 hours during the spring growth spurt. Secure the camera to a nearby post or tree, angled slightly downward toward the crown (the center of the fern) to capture the spectacular spiral expansion of the new fronds.

Because Man Ferns thrive in dark, damp spots, lighting is your biggest challenge. Avoid using a harsh direct flash, which can wash out the deep greens of the fronds. Instead, position your camera to take advantage of 'god rays'—those shafts of light that pierce the canopy in the early morning. If your camera has adjustable exposure settings, bumping the exposure up slightly can help reveal the intricate textures of the fibrous brown trunk.

Don't just point the camera at the plant; look for the visitors it attracts. Position a camera about 3-4 feet from the trunk at a 45-degree angle to catch birds like the Eastern Yellow Robin or various honeyeaters that often land on the trunk to forage for insects hiding in the fibers. In suburban settings, you might even catch a Ringtail Possum using the dense canopy as a daytime sleeping spot.

Lastly, ensure your camera is well-weatherproofed. Man Ferns require high humidity and frequent watering, so your equipment will be exposed to constant moisture. Use a desiccant pack inside the camera housing to prevent lens fogging, which is common in the damp microclimates where these ferns flourish.

Similar Species

Species that look similar or are commonly confused with man fern.

Rough Tree Fern

The Rough Tree Fern has a skinnier trunk with distinct oval leaf scars and lacks the soft, hairy texture of the Man Fern.

Slender Tree Fern

Has a much thinner, more delicate trunk and smaller fronds, typically found in even deeper, wetter rainforest settings.

Frequently Asked Questions

While they don't 'move,' Man Ferns are best observed in the early morning when the humidity is high. This is when you might see spore release or catch the morning light filtering through their translucent fronds.

You can't attract them like animals, but you can plant them! They require a shady, wind-protected spot with plenty of water. Keeping the trunk moist is the secret to a thriving tree fern.

Man Ferns are plants that create their own food through photosynthesis. However, they 'feed' on organic matter that gets trapped in their crown and leaches nutrients down the fibrous trunk to their roots.

Yes, they are very popular in shaded suburban gardens across southeastern Australia and in temperate climates globally, provided they have enough water and protection from the sun.

Look at the trunk and the base of the fronds. The Man Fern has a soft, furry brown trunk, while the Rough Tree Fern (Cyathea cooperi) has a trunk covered in hard, coin-shaped scars and feels much more prickly.
