Small annual temperature variation, high humidity, and high levels of annual precipitation makes Celtic Rainforest an important habitat for numerous common and rare species of
mosses,
liverworts, and
lichens.[2][3][4][5] The Scottish Natural History Scientific Advisory Committee writes, "the whole area is a lichenologists’ Mecca".[2] There is an exceptional number of
epiphytic plants (plants growing on or hanging from trees without being
parasitic).[2] The ground is covered with a deep blanketing of mosses and liverworts, which rise up the trunks of the trees onto the horizontal branches and up into the
canopy.[2]
