Natural Resource Monitoring at Upper Delaware Scenic and Recreational River

Ten Mile River, a tributary to the Delaware River.

NPS

Upper Delaware Scenic and Recreational River is one of nine parks in the Eastern Rivers and Mountains Network which is part of a nation-wide effort of the National Park Service to generate scientifically sound information on the changing conditions of park ecosystems. Each year, our scientists hike extensively throughout the parks stopping to collect information for the long-term monitoring programs listed below. Back at the office they analyze data and share the information with park managers to help them better understand how to best preserve park ecosystems for future generations.

To learn more about these programs and key findings, choose from the options below.

Long-term Monitoring Programs

• 

  River Water Quality

  Water quality characteristics are critical to understanding, protecting, and improving the fundamental condition of aquatic ecosystems.

• 

  Invasive Plants

  Parks monitor and manage invasive plants to protect important biodiversity and historic places.

Park Species Lists

Species lists are available from NPSpecies, the National Park Service's tool for documenting park biodiversity. Keep in mind that these species lists are a work-in-progress. Changes and updates are made as more species are shepherded through a rigorous vetting process. The absence of a species from a list produced with the tool below doesn't necessarily mean the species is absent from a park.

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.
