Concept Reference Code: B94KAR01HQUS
Name Used in Concept Reference: Quercus acerifolia
Taxonomic Comments: This species is sometimes treated as a variety of the widespread and abundant species Quercus shumardii (Smith, 1988), rather than as a distinct species (the treatment followed by Kartesz, 1994 checklist). However, Hess and Stoynoff (1998) have shown it to be a distinct species.

NatureServe Status

Global Status: G1
Global Status Last Reviewed: 23Feb2018
Global Status Last Changed: 04Apr1997
Ranking Methodology Used: Ranked by calculator
Rounded Global Status: G1 - Critically Imperiled
Reasons: This species is endemic to Magazine Mountain and the Ouachita Mountains in Arkansas, with four to six total occurrences and around five hundred individuals. The species has multiple threats that are not well understood but include recreational activities (ORVs and camping), gall wasps, and fire suppression as a result of encroaching development and other human activities. Trends are unknown.
Nation: United States
National Status: N1

NatureServe Global Conservation Status Factors

Range Extent Comments: Endemic to Arkansas and found on isolated portions of four mountains in the Ouachita Mountain Range on Sugar Loaf Mountain (Sebastian County), Pryor Mountain (Montgomery County), and Porter Mountain (Polk County)  and on Magazine Mountain (Logan County).

Area of Occupancy: 3-5 4-km2 grid cells
Area of Occupancy Comments:  

Number of Occurrences: 1 - 5
Number of Occurrences Comments: There are six occurrences at four general locations in Arkansas.

Population Size Comments: In 2005, the population size was estimated at a few hundred individuals  (probably on FS sites only) (USFS 2005) but the IUCN Red List Assessment cited 527 individuals surveyed in 2003 (Wenzell et al. 2016).

Number of Occurrences with Good Viability/Integrity: Unknown

Overall Threat Impact: Unknown
Overall Threat Impact Comments: The population on Sugarloaf Mountain is on private land and threatened by a variety of activities including trash dumping and recreation related to camping and off road vehicles. In addition, threats on this mountain including shale mining activity and electric tower construction. Fire suppression due to nearby settlements, threatens species on Magazine Mountain. (Wenzell et al. 2016). This species is a member of the red oak group and is probably susceptible to a number of diseases that are affecting red oaks including a gall wasp (cynipid wasp) that is thought to be impacting acorn Production. Plants on forest service land are protected by bluffs and steep slopes (USFS 2005). On Forest Service land, the greatest threats are scientific collection and recreational activities (USFS 2005).

Short-term Trend: Unknown

Long-term Trend: Unknown

Management Summary
Help
Stewardship Overview: This species occurs in an area with steep, rocky terrain keeping it fairly protected. Scientific collection of the species and disturbance at nearby recreation sites seem to be the greatest threats on Forest Service Land (USFS 2005). Permits are required to collect this species, and the number of permits issued should be monitored. This species has probably been protected from timber harvest given its habitat (USFS 2005), however, it would benefit from canopy thinning. Finally, this oak is in the red oak group which is susceptible to a number of diseases, including the red oak borer and gall wasps. Signs of the red oak borer and gall wasps should be monitored. Given the few locations and small population size, disease could be devastating to this species. Nursery stock for this species is being grown in the event of a natural catastrophe. Population numbers of this species should be monitored to allow rapid action in the case of a dramatic decline.
