The yellow iris, or yellow flag iris, pictured above, has been found on two properties on Armour Lake. It is an invasive species that reduces habitat available for wildlife, including native fish habitat and bird nesting and rearing sites. The dense mats can block water flow in irrigation and flood control ditches. Yellow iris is poisonous to both humans and animals if eaten. If you find this plant on your property, please remove it or watch it carefully as it can spread quite quickly.
