What does "at risk" mean?

Each of the plants in the virtual gallery is at risk. This means that these plants are not as common as other plants, and if they continue to lose habitat or are threatened by some other cause, they may disappear from Saskatchewan. Some plants are more at risk than others.

A plant that has been extirpated has already been lost from this province, but occurs somewhere else.

A plant that is endangered still grows in the wild in Saskatchewan, but there are fewer than five sites where this plant is found.

Threatened plants are not in as much danger as endangered plants. They can be found at 6 to 15 places in the province.

Vulnerable plants are not in immediate danger of becoming extirpated, but they are still not common.
