Heardov ostrov, ktor\u00fd je zo 61 % pokryt\u00fd \u013eadom a dominuje mu akt\u00edvna sopka Big Ben, ktorej v\u00fd\u0161ka presahuje 2 800 metrov, je pova\u017eovan\u00fd za jeden z posledn\u00fdch nedotknut\u00fdch ekosyst\u00e9mov sveta a je zap\u00edsan\u00fd na zozname svetov\u00e9ho dedi\u010dstva UNESCO.

V\u00fdsledn\u00fd invent\u00e1r \u013eadovcov katalogizuje 29 \u013eadovcov a sleduje ich obrysy v rokoch 1947, 1988 a 2019, pri\u010dom dokumentuje k\u013e\u00fa\u010dov\u00e9 morfologick\u00e9 znaky.<\/p>\n
