Classificado como Vulneravel, com populacoes sob severa pressao devido a rapida perda de gelo marinho artico causada pelas mudancas climaticas.

Stigonema tomentosum e uma cianobacteria filamentosa da ordem Stigonematales, avaliada como Pouco Preocupante (LC). Forma tricomas multisseriados e ramificados e tipicamente cresce em habitats terrestres umidos como rochas umidas, solo e casca.
