The flora of the Canadian Arctic contains 236 rare vascular plant taxa that represent a unique part of Canadian biodiversity. This list of rare species includes an introduction in which terms are defined, the most important of which are those associated with rarity and the limits of the Canadian Arctic. As well, the criteria used to determine a taxon's rarity are described. For each taxon, a comment is included on phytogeography, occurrence, and rare status in other parts of Canada. A distribution map showing known occurrences in the Canadian Arctic is included for each species.

This list was compiled to promote awareness of rare plants in Canada's flora, and also to promote awareness of their ecosystems and the need to preserve them. The list includes all native taxa, above the rank of form, that are rare in each of the provinces and/or territories in which they occur. Hybrids and naturalized species are not included. Information given for each includes scientific name and authority, synonyms, family name, references, endemism, nature conservancy rank, Canadian priority, and Committee on the Status of Endangered Wildlife in Canada status. Plants are also listed by family, endemic, province or territory, and priority.

As human populations expand and have increasing access to technol ogy, two general environmental concerns have arisen. First, human pop ulations are having increasing impact on the earth system, such that we are altering the biospheric carbon pools, basic processes of elemental cycling and the climate system of the earth. Because of time lags and feedbacks, these processes are not easily reversed. These alterations are occurring now more rapidly than at any time in the last several million years. Secondly, human activities are causing changes in the earth's biota that lead to species extinctions at a rate and magnitude rivaling those of past geologic extinction events. Although environmental change is potentially reversible at some time scales, the loss of species is irrevo cable. Changes in diversity at other scales are also cause for concern. Habitat fragmentation and declines in population sizes alter genetic di versity. Loss or introduction of new functional groups, such as nitro gen fixers or rodents onto islands can strongly alter ecosystem processes. Changes in landscape diversity through habitat modification and frag mentation alter the nature of processes within and among vegetation patches. Although both ecological changes altering the earth system and the loss of biotic diversity have been major sources of concern in recent years, these concerns have been largely independent, with little concern for the environmental causes the ecosystem consequences of changes in biodiversity. These two processes are clearly interrelated. Changes in ecological systems cause changes in diversity.
