Story: Human effects on the environment

Hawkweed (3rd of 3)


Different types of hawkweed (Pilosella and Hieracium species) are native to Europe and north Asia. They favour dry, sunny areas, and grow well in sandy and less fertile soils. Hawkweed is highly invasive, and has become a serious weed in New Zealand, especially in tussock grasslands. Once established, it is difficult and costly to remove. This mouse-ear hawkweed (Pilosella officinarum), in the Irirangi swamp in the central North Island, has smothered almost all other growth.
