In 1781 Nathanael Greene, commanding General of the Continental Army's Southern Department, was defeated at Guilford Courthouse by the British General Lord Cornwallis. Although Greene's army suffered defeat, his losses were slight, whereas Cornwallis suffered overwhelming losses, a situation that greatly hastened the end of the Revolutionary War. Guilford Courthouse National Military Park's 243-acre site preserves the battlefields and commemorates the battle with 28 monuments. At the time of the battle, this area was predominantly under cultivation. Today, the park contains mowed fields and flat upland woods of mixed pine and hardwoods, particularly oak species.

The Cumberland Piedmont Network I&M program has provided this park with a vegetation community classification and map, a wetlands inventory, and updated vascular plant and vertebrate species lists. During the vegetation community classification work, 11 distinct associations were documented and mapped, including an interesting small-stream sweetgum forest.

The network monitoring program at this park includes four vital signs that involve repeated visits to established sites, following procedures established by each monitoring protocol. These four vital signs are: forest vegetation communities, invasive species early detection, ozone/foliar injury, and water quality. Water quality monitoring began in 2004 and continues on a quarterly schedule every-other-year (even years) at three sites. Forest monitoring began in 2011–2012 with the establishment of 16 long-term monitoring plots. Additional plots will be established in upcoming years, followed by a five-year revisit schedule, occurring in early June. Ozone levels and foliar injury are assessed on-site every six years, beginning in 2012. The Invasive Species Early Detection protocol was completed in 2012 and will be used by field crews to monitor for priority exotics during their scheduled field work.

Park managers are using inventory and monitoring data to create resource stewardship strategies for achieving desired future conditions. The links to inventory and monitoring reports are provided on this page.

Species Attribute Definitions

Definitions

Occurrence

Occurrence values are defined below. One or more Occurrence Tags may be associated with each Occurrence value.

Present: Species occurs in park; current, reliable evidence available.

Probably Present: High confidence species occurs in park but current, verified evidence needed.

Unconfirmed: Species is attributed to park but evidence is weak or absent.

Not In Park: Species is not known to occur in park.

---

Occurrence Tags

Adjacent: Species is known to occur in areas near to or contiguous with park boundaries.

False Report: Species was reported to occur within the park, but current evidence indicates the report was based on misidentification, a taxonomic concept no longer accepted, or other similar problem of error or interpretation.

Historical: Species' historical occurrence in park is documented. Assigned based on judgment as opposed to determination based on age of the most recent evidence.

---

Abundance

Abundant:

• Animals: May be seen daily, in suitable habitat and season, and counted in relatively large numbers.
• Plants: Large number of individuals; wide ecological amplitude or occurring in habitats covering a large portion of the park.

Common:

• Animals: May be seen daily, in suitable habitat and season, but not in large numbers.
• Plants: Large numbers of individuals predictably occurring in commonly encountered habitats but not those covering a large portion of the park.

Uncommon:

• Animals: Likely to be seen monthly in appropriate habitat and season. May be locally common.
• Plants: Few to moderate numbers of individuals; occurring either sporadically in commonly encountered habitats or in uncommon habitats.

Rare:

• Animals: Present, but usually seen only a few times each year.
• Plants: Few individuals, usually restricted to small areas of rare habitat.

Occasional:

• Animals: Occurs in the park at least once every few years, varying in numbers, but not necessarily every year.
• Plants: Abundance variable from year to year (e.g., desert plants).

Unknown: Abundance unknown

---

Nativeness

Native: Species naturally occurs in park or region.

Non-native: Species occurs on park lands as a result of deliberate or accidental human activities.

Unknown: Nativeness status is unknown or ambiguous.

List Differences

The Checklist contains only those species that are designated as "present" or "probably present" in the park.

The Full List includes all the checklist species in addition to species that are unconfirmed, historically detected, or incorrectly reported as being found in the park. The full list also contains species that are "in review" because their status in the park hasn't been fully determined. Additional details about the status of each species is included in the full list.

The checklist will almost always contain fewer species than the full list.
