The canal travels from the coastal plain of Washington, DC, to the mountains of western Maryland. The many habitats along that journey from sea level to the mountains rank C&O Canal among the most biodiverse national parks.

Keep wildlife wild! Please enjoy and observe wild animals from a distance. Photograph all wildlife from a safe distance. Use telephoto lenses and observe quietly. Animals can be very protective of their young and can become aggressive if cornered.
It is dangerous and illegal to feed wild animals, including ducks and geese, in national parks. Wildlife can become dependent on handouts and lose their ability to forage for food. Such animals can lose their fear of humans and become threatening.
Some animals found in the Park can carry rabies. If you encounter an animal that is acting strangely (for example, a nocturnal raccoon seen during the day) or an animal has attacked you, immediately report it to our emergency Dispatch Center, at 866-677-6677. Please visit the CDC website to learn more about rabies.
Species checklist
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.

From coast to coast, the NPS Inventory and Monitoring Division is helping park managers improve the health and function of forest ecosystems. From promoting resilient forests in the Northeast, to conserving whitebark pine in the West, to protecting Hawaiian forest birds from avian malaria, scientific partnerships are helping parks to share information, leverage funding sources, and work together for outcomes that extend beyond what any park could accomplish on its own.

To steward amphibians effectively, managers need basic information about which species live in parks. But species lists need constant maintenance to remain accurate. Due to recent efforts, the National Park Service now has an up-to-date amphibian species checklist for almost 300 parks. This information can serve as the basis for innumerable conservation efforts across the nation.

Amphibians are a crucial part of both aquatic and land ecosystems, and National Capital Region parks are home to at least 20 different amphibian species. Learn how amphibian populations are changing based on more than fifteen years of NPS monitoring by the National Capital Region Inventory & Monitoring Network.

Explore how forest interior breeding birds are faring in National Capital Region (NCR) parks. These species prefer the shadiest and quietest core of the forest landscape and are excellent indicators of a healthy forest ecosystem. We look at data on wood thrush, ovenbird, Kentucky warbler, Louisiana waterthrush, hooded warbler, and scarlet tanager from a report summarizing population trends for forest birds in NCR parks.

The C&O Canal's Potomac Gorge area is rich with a wide variety of frogs and salamanders. From wood frogs and red-spotted newts to marbled salamanders and toads, these amphibians are part of what makes the Potomac Gorge (the area around Great Falls) a unique and treasured place.
