Natural Resources at Hubbell Trading Post National Historic Site

Hubbell Trading Post National Historic Site

NPS

Hubbell Trading Post National Historic Site encompasses 161 acres (65 ha) on the Navajo Nation in northeastern Arizona. First designated as a National Historic Landmark in 1960, it was later designated as a National Historic Site in 1965. Located in the Ganado Valley at the base of Defiance Plateau, Hubbell Trading Post is the oldest continuously operating trading post on the Navajo Nation.

Shrubland communities predominate at Hubbell, with a small area pinyon-juniper woodland. Much of the natural landscape at the park had been heavily manipulated by humans, who grazed livestock here and cultivated the land. However, after the NPS fenced out livestock, native plants and animals became more abundant.

Hubbell Trading Post NHS supports 2 amphibians, 86 birds, 5 fishes, 4 mammals, and 4 reptile species. The main water resource in the park is the intermittent flow in Pueblo Colorado Wash.

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.

Life Zones

Hubbell Trading Post NHS has a very narrow elevation range (6,298-6,383 ft / 1,920–1,946 m) and is situated primarily in the Pinyon-Juniper Woodland life zone. Although juniper woodlands can be seen on the surrounding hills, almost no woodlands are present in the monument due to historic land use. Hubbell Trading Post has an average annual precipitation of 10.6 inches (269 mm).

Inventory Reports

Inventories are point-in-time surveys that help us learn about the resources in our parks. Information obtained through the Southern Colorado Plateau Network’s inventories of park resources helped to establish a base level of data, which has served as a starting point for our natural resource monitoring.
