Concept Reference: Kartesz, J.T. 1994. A synonymized checklist of the vascular flora of the United States, Canada, and Greenland. 2nd edition. 2 vols. Timber Press, Portland, OR.
Concept Reference Code: B94KAR01HQUS
Name Used in Concept Reference: Acer saccharum
Taxonomic Comments: The sugar maple and the black maple are treated by Kartesz (1994, 1999) as different species (Acer saccarum and Acer nigrum, respectively); they are sometimes considered to be subspecies or varieties of the same species (in which case the name Acer saccharum has nomenclatural priority, with the black maple being called Acer saccharum ssp. nigrum or Acer saccharum var. nigrum). Note that the species Acer saccharinum (silver maple) has a similar name.

NatureServe Global Conservation Status Factors

Range Extent Comments: Ranges across North America from Maine and eastern Canada to Minnesota and the eastern Dakotas, southward to Mississippi, eastern Texas, and central Oklahoma.

Area of Occupancy: >12,500 4-km2 grid cells
Area of Occupancy Comments: Present in much of this area, and often locally abundant (at least before clearing for agriculture and urban development, which nevertheless left scattered individual trees [valued for maple sugar production] in yards, fencerows, roadsides, and farm woodlots).

Number of Occurrences: > 300
Number of Occurrences Comments: Widespread and abundant in the eastern and midwestern United States, into southern Canada. While essentially continuous in large areas (at least before fragmentation due to agriculture and development), the main range can be considered to include many hundreds of reasonably independent, self-maintaining stands. Nevertheless, genetic mixing by storm-blown pollen and seeds lead to metapopulation dynamics within aggregations of such areas. There are also a number of outlying stands that can be considered occurrences as well.

Population Size Comments: As a common canopy co-dominant in a large range, there are easily far more than a million mature sugar maple trees within the natural range, even ignoring cultivated plants.

Number of Occurrences with Good Viability/Integrity: Very many (>125)
Viability/Integrity Comments: Many stands of this common canopy tree are stable, long-persisting, and presumably viable.

Overall Threat Impact: Low
Overall Threat Impact Comments: Relatively unthreatened. Harvested commercially for its high-quality wood, but generally selectively with younger trees able to fill gaps. Losses due to development (often in forested abandoned farmland) have local impact but do not appear to be eliminating the species from substantial areas.

Short-term Trend: Relatively Stable (<=10% change)
Short-term Trend Comments: MOre or less stable, with colonization of abandoned farmland or maturing forest lands counterbalancing losses from land clearing for development.

Long-term Trend: Decline of 30-50%
Long-term Trend Comments: Lost many individuals (and entire stands) to 19th-century agricultural clearing and to continued development in the 20th and early 21st centuries.

Intrinsic Vulnerability Comments: An ecologically very successful tree, often becoming dominant or co-dominant in upland areas.

Environmental Specificity: Broad. Generalist or community with all key requirements common.
Environmental Specificity Comments: Relatively broad habitat amplitude (although doing best on mesic but not hydric soils), in a wide climatic range over a host of bedrock types, including glaciated areas.
