... and different burning qualities. Coal fungus and tinder fungus (and chaga) are slower burning tinders that will smolder for long periods and are great for storing heat for later ignition of other tinders and fuel (hence they are transportable). Whereas, the fluffy cotton from a cattail, hair from your head and magnesium shavings for example are "flash" tinders and they need a secondary tinder to catch and sustain the ignition of your fuel bundle because they just burn too fast.

The biggest thing people need to take away is that not only is natural tinder a great material but it often needs to be processed and broken down into smaller fibres as the person in the video aptly showed. Fabricating birds nests/bundles and gathering all the fuel before igniting is necessary otherwise you are left with a very short term fire.

Note: I've never used thistle or fireweed before - I shall have to give them a try.
