What are rare trees?

Rare trees are not necessarily threatened or endangered.  In most cases, the native distribution is a small area due to geological and/or environmental restraints, or growth requirements.  Criteria for rare plants generally are as follows:
    • 20 to 35 extant sites, or
    • 3,000 to 5,000 individuals statewide.

What does 'Endangered' or 'Threatened' Status mean?

• 5 or fewer extant sites, or
    • fewer than 1,000 individuals

Rare plants do not usually have protection like those with designation like 'threatened' or 'endangered'; however, they may still be protected under local laws.  In New York for example, rare plants have been protected since 1933, but it is the land owner, not the government, who is responsible. 
See additional resources for more information.
The U.S. Endangered Species Act defines the terms as species that are "in danger of extinction within the foreseeable future throughout all or a significant portion of its range," while threatened refers to “those animals and plants likely to become endangered within the foreseeable future throughout all or a significant portion of their ranges.”  While apparently not as enforced as in the United States, Canada's
