Dear student , Lichen usnea , also known as old man`s beard is infalmmable in nature. So, it causes forest fire during summer season ....With Regards ...Mahima ( Askiitians Forum Expert )

usnea has high surface to volume ratio so it dries more rapidly than other lichens and when these lichens come in contact with each other then due to friction the chances of a wildfire increase. hope this helped. please approve if it did.
