Park Science

Manassas National Battlefield Park offers an ideal natural laboratory in which to study a wide variety of research topics. Important science issues at the park include, but are not limited to, air pollution, water quality, habitat fragmentation, invasive exotic species, rare species conservation and restoration of disturbed natural and cultural landscapes. Manassas National Battlefield Park is characterized by gently rolling hills with a patchwork of open fields and forests.The park's landscape is representative of the Culpeper basin and is one of the region's most unspoiled areas.

National Park Service staff, experts from other federal agencies, scientists and graduate students in academia, and independent researchers conduct scientific research in the park. Prospective researchers must apply for a permit.

Species List

One of the primary goals of the National Capital Region Network (NCRN) is to develop and maintain verified, substantiated, and certified vascular plant and vertebrate species lists for each network park. The information presented in these web-based species lists are subsets of data managed in NPSpecies, which is the master biodiversity database for the National Park Service, and is the tool used by NCRN for meeting this goal.

The species lists presented here have all gone through a certification process. This involves the evaluation and review of the species information by local experts who are well-versed in the biology, taxonomy, and nomenclature of species in the network parks.

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.
