Unpublished specimen data from a number of field botanists, most particularly Paul M. Catling, William J. Crins William Draper, Albert Dugal, the late Clarence Frankton, Catherine J. Keddy, Michael J. Oldham, Joyce M. Reddoch and David J. White, were incorporated into this list over a period of several years. Application of these unpublished data have supplemented in-house knowledge of the vascular plants of Ottawa gained both from extensive field experience and from off-site floristic research. The contributions from other field botanists have significantly enhanced the usefulness of the final list.

 

Many additional records were gleaned from examination of the herbarium specimens, as noted in the Introduction (above). Those preserved at Agriculture Canada (DAO) and the Canadian Museum of Nature (CAN) constitute particularly large and important information sources. Collection managers Gizčle Mitrow and Michael Shchepanek (respectively), greatly facilitated these herbarium investigations.

 

A number of taxonomic specialists were consulted for identifications and/ or nomenclatural insight for some of the plant groups addressed. These include Donald M. Britton, University of Guelph (pteridophytes), George W. Argus, Canadian Museum of Nature (Salicaceae), William J. Crins, Ontario Ministry of Natural Resources (Cyperaceae; Juncaceae; Poaceae), Stephen Darbyshire, Agriculture Canada (Poaceae), Paul M. Catling, Agriculture Canada (Cyperaceae, Orchidacae, Juncaceae), John Semple, University of Waterloo (Asteraceae), Gerald Mulligan, Agriculture Canada (Brassicaceae), Erich Haber, Canadian Museum of Nature (Pyrolaceae), James Phipps, University of Waterloo (Rosaceae) and Tony Reznicek, University of Michigan (Cyperaceae).

 

The annotated list was enhanced significantly by the reviews of botanists Michael Oldham, David White, Paul Catling and Albert Dugal. These gentlemen provided numerous valuable comments, corrections, additions and observations. Any errors or emissions which may have escaped their sharp eyes, however, remain the author’s responsibility.

 

This document also benefited from the efforts of Bernie Muncaster, Muncaster Environmental, in the development of the generic index, and through the work of Susan Murphy, City of Ottawa, in final production.


 

1.0 INTRODUCTION

 

Accurate identification of the diversity and abundance of species occurring in a particular site provides a valuable indication of the ecological significance of that area’s natural habitats. It also provides important information on possible mitigation, restoration and/ or conservation opportunities. Trends in both population size and the total diversity of significant native species also provide valuable tools in monitoring the overall ecological health of landscapes. Significant species abundance and occurrence information extracted from an earlier floristic data base (Brunton 1998), for example, has been applied to various environmental management purposes in the City of Ottawa, including sensitive areas determinations, the relative rating of different natural areas, and for ecological integrity monitoring. None of these applications can be confidently undertaken, however, without an accurate and comprehensive listing of floristic diversity.

 

A total of 1,569 species, subspecies and hybrid vascular plant taxa are known to occur (or to have occurred) within the City of Ottawa (former Region of Ottawa-Carleton). Nomenclature in the following list generally follows the most recent taxonomic treatments (e.g. Flora of North America series), with synonyms frequently employed in the Ottawa area noted in brackets. The annotated list  is compiled from a variety of sources, including:

 

·        review of verifiable regional literature (see References);

·        examination of preserved specimens in the major contemporary depositories of City of Ottawa floristic information, including the Canadian Museum of Nature (CAN), Agriculture Canada (DAO), the Royal Ontario Museum (TRT) and the private herbarium of Daniel F. Brunton (Dfb);

·        input from experienced and expert field botanists (see Acknowledgments).

 

 

1.1 Status of native taxa

 

The native vascular flora of the City of Ottawa (former Region of Ottawa-Carleton), including a small number of taxa with both native and non-native populations, includes 1,014 vascular plant species, subspecies and hybrids. Native species designated as ‘Common’  occur frequently within the City of Ottawa, often in large numbers, throughout their appropriate, typically widespread habitat(s). ‘Uncommon’ taxa are found only occasionally within suitable habitat, often in small numbers. The habitat of ‘Uncommon’ species is often geographically limited as well. ‘Rare’ taxa in Ottawa (their names highlighted in bold type) represent native species, subspecies and varieties which further designated as follows:

 

 

(PS)  Provincial Conservation Concern - typically known from fewer than 100 populations known in Ontario; the NatureServe subnational conservancy status rank (SRANK) assigned to each species by the Ontario Heritage Information Centre (Oldham 1999) is noted, followed by the statement of their status in Ottawa. NatureServe codes employed here are:

 

o       S1 - Extremely rare in Ontario; usually 5 or fewer occurrences;

o       S2 - Very rare in Ontario; usually between 6 and 20 occurrences or with many individuals in fewer occurrences;

o       S3 - Rare in Ontario; usually between 21 and 100 occurrences;

o       S4 - Uncommon to locally common in Ontario and apparently secure; usually between 101 and 1000 occurrences.

 

The provincial status of such taxa are updated, when and as data become available. Such changes can be reviewed at any time on the Ontario Heritage Information Centre web page:  http://www.mnr.gov.on.ca/MNR/nhic/species/listout_track.cfm?el=p&alpha=a.

 

(RS) - Regionally Significant - known from 10 or fewer contemporary populations (post-1969) in the City of Ottawa. This includes the Rare (5 or fewer populations) and Sparse (6 to 10 populations) categories employed by Gillett & White (1978) and Brunton (1998). Species known only from pre-1970 records are annotated as Rare (Historic). The year 1970 was selected as a reasonable limit of our understanding of ‘contemporary’ since it constitutes a sufficiently long period of time (35 years)  for the development of a comprehensive set of data while still offering the likelihood of substantially unchanged site conditions at particular locations.

 

Some listings for native vascular plant species are annotated in the ‘Sites/ Status’ column to provide additional information on their status within the City of Ottawa. Those qualifiers include:

 

o       [site name]* - an asterisk following a particular site name indicates that two to four separate populations of this significant species are known from this particular site. If the number of populations (geographically separated occurrences) within a particular location is known to be greater than four, that is explicitly stated.

 

o       Uncommon [number] - a bracketed numeral in the status column indicates the number of sites (under 20) for species which were previously considered to be Regionally Rare in Gillett & White (1978) and/ or Brunton (1998) but for which between 11 and 20 contemporary populations are known. These are considered to have a measure of special features significance at a Regional (City of Ottawa) level but not to the level of Regionally Rare taxa. The names of such species are cited in bold type to further distinguish them more widespread uncommon taxa.

 

Native hybrids involving at least one rare parent are also considered Regionally Significant. Hybrids between common or uncommon taxa, and adventive species (taxa native elsewhere in North America but occurring here as a result of human activity), are not so listed however.

 

Status statements reflect the known distribution of each taxon as supported by specimens in significant City of Ottawa voucher collections. Credibly documented citations in botanical literature and reports (as listed) are also considered. Populations known from somewhat older records (1950-1969) from sites likely to have retained those particular species (e.g. the middle of large area known to have maintained its natural character) are also included as ‘contemporary. The status statement for species with both native and introduced populations applies to the native portion of the population, unless otherwise stated.

 

 

1.2 Non-native (introduced) taxa

 

A substantial proportion (36%) of the flora of the City of Ottawa is not native to this area. These 571 taxa are indicated by the symbol ‘#’ in the column following their scientific name. Taxa so indicated include species and hybrids not native to North America (introductions), as well as adventives - taxa native elsewhere in North America but established in the City of Ottawa as a result of ±recent (historic period) human activity.

 

Species marked with the introduced symbol within square brackets ‘[#]’ have both native and non-native populations in Ottawa. As noted above, status statements for species with both native and introduced populations apply to the native populations.

 

Status designations for non-native plants species are less precise than they are for native taxa since the interpretation of such information is typically less useful. This reflects the frequently arbitrary distribution of such human-assisted plants and their limited or even negative natural environment values. In that regard, it can be especially difficult to determine if ‘wild’ occurrences of cultivated plants represent individuals persisting after planting or established, reproducing populations. We have erred on the side in including such ambiguous taxa on the list.

 

Non-native taxa designated as ‘Common’ are present in large numbers in at least a substantial portion of the City of Ottawa (e.g. several geographic townships). ‘Uncommon’ non-native taxa are seen infrequently in the City, typically occurring in small numbers but over a relatively large area of the municipality. ‘Rare’ non-native species are known from a small number of contemporary records, typically five or fewer populations being known.

 


1.3 New Data

 

A data base such as this is dynamic and reflects the state of knowledge of a complex subject at a particular time. In this case, the cut-off date is 15 April 2005. While it is important and  worthwhile to periodically present such data in a single package, new information continues to accumulate. Documentation of supplementary data, therefore, is important for the maintenance of a complete and applicable data base. Users of floristic data in Ottawa, be they amateur naturalists or professional field botanists, can make important contributions by documenting such observations and findings.

 

The most useful method for documenting new records is through preservation of a suitably prepared voucher specimen in a public herbarium, such as one of the collections cited in this document. Observations of species of Conservation Concern can also be documented by filing a Species Report on the Ontario Natural Heritage Centre web page at  http://www.mnr.gov.on.ca/MNR/nhic/species/listout_track.cfm?el=p&alpha=a. The record becomes part of the province-wide data base directing many conservation and management efforts across Ontario. Reports of additional records of significant Ottawa vascular plant taxa would also be welcomed by the author (bruntonconsulting@rogers.com).
