По состоянию на сентябрь 2021 года [update]Международный союз сохранения природы (МСОП) оценил статус сохранения 15 видов в хромисте . [ 1 ] МСКН не оценил никаких протестических видов, кроме как в Chromista. Никаких подвидов хромиста или субпопуляции не были оценены. Оцененные виды хромиста не подтверждаются вымершими , но четыре помечены как, возможно, вымершие.
По состоянию на 2005 г. [update] Система классификации угроз в Новой Зеландии оценила 38 видов макроводорослей как угроза и 23 как дефицитные данные. [ 2 ] Некоторые из этих видов вызывают озабоченность только на национальном уровне. [ 2 ]
