Lichens are the primary winter forage for large herds of migratory caribou (Rangifer tarandus). Caribou select for lichens more than they are available across the landscape and they generally avoid, during winter, habitat that has been burned by wildfires for decades while lichen abundance recovers.

Do arctic caribou eat lichen?
Caribou are some of the few animals that can eat this abundant plant. Daily they eat an average of about 3 kilograms of lichens. This is the equivalent of eating 2 garbage bags full of lichens a day. Compared to most plants lichens are very tough and contain acid which might keep other animals away.
What species eat lichens?
Lichens are eaten by many small invertebrates, including species of bristletails (Thysanura), springtails (Collembola), termites (Isoptera), psocids or barklice (Psocoptera), grasshoppers (Orthoptera), snails and slugs (Mollusca), web-spinners (Embioptera), butterflies and moths (Lepidoptera) and mites (Acari).
What animals eat reindeer lichen?
Animals such as Reindeer and Caribou feed on lichen during the coldest periods of the season. They do this because it is one of the only things that they have for food when the weather is cold and there is little other vegetation left.

Food can be scarce in the Arctic, but the hares survive by eating woody plants, mosses, and lichens which they may dig through the snow to find in winter. In other seasons they eat buds, berries, leaves, roots, and bark.
Can humans eat lichens?
Edible lichens are lichens that have a cultural history of use as a food. Although almost all lichen are edible (with some notable poisonous exceptions like the wolf lichen, powdered sunshine lichen, and the ground lichen), not all have a cultural history of usage as an edible lichen.

Caribou live in colder remote areas of the world, such as Canada and Alaska, in forests, woodlands, and the tundra. What animal eats Caribou? Grizzly bears and wolves are the primary predators of caribou.
What type of lichen do caribou eat?
The lichen that caribou enjoy as an important food source is primarily found on the forest floor, aptly named “reindeer lichen”. Lichen is very slow growing and flourishes where most plants can’t.
Why caribou eat lichens in the winter?
Lichens are the primary winter forage for large herds of migratory caribou (Rangifer tarandus). Caribou select for lichens more than they are available across the landscape and they generally avoid, during winter, habitat that has been burned by wildfires for decades while lichen abundance recovers.

Why is it called reindeer moss?
The moss grows in lush mats over large areas of the ground and is the one of the food sources, along with leaves, willow and grasses, for Reindeer during the winter, hence it’s common name is Reindeer Moss. Moose, Caribou and Musk Oxen also feed on this moss.
Do polar bears eat arctic hares?
Polar bears can detect a carcass from nearly 20 miles away with their extraordinary sense of smell and will feed on the bodies of beached bowhead whales and other remains. They’ll also eat fish, shellfish, waterfowl, eggs, rodents and hares.
Why do reindeer eat lichen?
Thanks to the algae, lichen doesn’t require much sunlight to produce chlorophyll; the spongy material of the fungus also holds up well against the harsh temperatures. Reindeer sniff out lichen beneath the snow and use their curved hooves or antlers to uncover it.
What is usnea used for?
Usnea is used for weight loss, pain, fever, and wound healing, and to make phlegm easier to cough up. Usnea is also used directly on the skin for sore throat and for athlete’s foot.
Do caribou eat lemmings?
They mainly eat lichens in winter, especially reindeer moss. However, they also eat the leaves of willows and birches, as well as sedges and grasses. There is some evidence to suggest that on occasion they will also feed on lemmings, arctic char and bird eggs.

Are lichens good or bad?
Are There Any Benefits of Lichen? Surprisingly, lichen can actually be of benefit. It’s a natural air quality indicator, as it absorbs everything in the environment around it, but only thrives when the air quality is clean. In fact, scientists use lichen as a measure of air quality in different areas.
Are lichens poisonous?
Very few lichens are poisonous. Poisonous lichens include those high in vulpinic acid or usnic acid. Most (but not all) lichens that contain vulpinic acid are yellow, so any yellow lichen should be considered to be potentially poisonous.
Is lichen a food source for animals?
Lichens serve as a food source for many animals besides caribou, such as moths, slugs, and mites.
Do mule deer eat lichen?

What do lichens need to survive?
Lichens need clean, fresh air to survive. They absorb everything through their cortex. From beneficial nutrients to harmful toxins, lichens absorb it all. They also absorb water in the air, which is why so many are found in fog belts along oceans and big lakes.
Why are lichens considered used to monitor pollution levels?
Lichens are sensitive to atmospheric pollution such as nitrogen (N) because they receive all their nutrients and water from wet and dry atmospheric deposition (fall out). Nitrogen deposition can increase the load of nutrients.

What is lichen and mosses?
Both mosses and lichens are considered non-vascular plants, but only mosses are truly plants, according to the U.S. Forest Service. Lichens aren’t plants at all. They are complex organisms formed by a symbiotic relationship between a fungus and an algae or cyanobacteria (or, in some cases, both).
