The Hawaiian Volcano Observatory, on Hawaiiâs Big Island, has been monitoring volcanoes since 1912ânearly four decades before Hawaii became a state. Today itâs considered one of the worldâs leading observatories. Yet thereâs little coordination between even the best observatories in the United States.
An asterisk (*; from Late Latin asteriscus, from Ancient Greek á¼ÏÏÎµÏÎ¯ÏÎºÎ¿Ï, asteriskos, little star) is a typographical symbol or glyph. It is so called because it resembles a conventional image of a star.
Weeds that are not yet common or established but pose a significant threat are identified by an asterix. Weeds that are identified as Weeds of National Significance are noted as WoNS.hese plants typically produce large numbers of seeds, often excellent at surviving and reproducing in disturbed environments and are commonly the first species to colonise and dominate in these conditions. Weeds may reduce native biodiversity, affect agricultural productivity, the environment, human health and amenity.
