The letters SNC following a species, indicate that it was found, to date, only on South Nation Conservation property within Larose Forest.
Species of note
Native species considered regionally and provincially significant are indicated in green and red, respectively.
Regional status
Regionally significant plants are inferred from Brunton 2005. Brunton's work is the most recent flora for this part of Eastern Ontario, but Larose Forest lies just beyond the boundaries covered by this work. However, it is reasonably safe to extrapolate that the plants found there have a similar status.
| Regionally significant | Native "plants known from 10 or fewer contemporary populations (post-1969) in the City of Ottawa" |
| Rare | Non-native species "known from a small number of contemporary records, typically 5 or fewer populations being known" |
Provincial status
Provincial ranking and definition follows the Ontario Natural Heritage Information Centre (NHIC) list, which is updated on an ongoing basis.
| S1 | Critically imperiled in Ontario; usually 5 or fewer occurrences |
| S2 | Imperiled in Ontario; usually between 6 and 20 occurrences |
| S3 | Vulnerable in Ontario; 80 or fewer occurrences |
| S3-S4 | Rare to uncommon in Ontario |
| S4 | Apparently secure in Ontario; uncommon but not rare; some cause for long-term concern due to declines or other factors |
An asterisk (*) indicates a non-native species.
