Northern corrboree frogs spend most of their time in the woodlands, going to the waterlogged grasslands in the summer to breed. Females lay around 25 eggs in damp vegetation, and hatch when water levels rise. The northern corrboree frog is listed as critically endangered and has decreased massively, due to chytrid, weeds, droughts, climate change, and livestock.
