Inventory & Monitoring at Mojave National Preserve

Mojave National Preserve was established in 1994 as part of the California Desert Protection Act. The park encompasses 1.6 million acres, making it the third-largest unit of the national park system in the contiguous United States.

Located in the southern California and bordered to the north and south by major interstate highways, I-15 and I-40, the preserve is an expanse of desert lands from three of the four major North American deserts: the Great Basin, Sonoran, and Mojave. The preserve has vast natural and cultural resources that warrant monitoring and protection.

The Mojave Desert Network provides natural resource inventory and monitoring information to help parks make effective, science-based management decisions. Inventories have been completed for mammals, fish, birds, vascular plants, and reptiles & amphibians (see species lists further down the page). Maps and reports detailing Mojave Preserve's vegetation, geologic and soil resources are also complete.

Our Selected Large Springs monitoring focuses on MC Spring, an iconic water source due to the endangered Mohave tui chub (Siphateles bicolor mohavensis) that inhabits it. The network also published a report on the use of historic photographs to reconstruct the water level at MC Spring from 1990 to 2015.

Monitoring at Mojave National Preserve

Ongoing Monitoring Efforts
Bats monitoring bat populations using acoustic and capture surveys
Desert Springs monitoring water quality and availability at nearly 100 smaller seeps and springs
Integrated Uplands vegetation and soils monitoring of the mixed creosote community
Invasive & Exotic Plants monitoring plan for detecting invasive plants throughout the Park
Selected Large Springs monitoring water quality and availability at MC Spring
Spring Vegetation monitoring desert spring plant communities at select springs
Weather and Climate monitoring temperature, precipitation, wind and other variables at park service and partner weather stations

Reports & Publications

Inventories & Assessments present baseline data collected during the first phase of the development of the Mojave Desert Inventory & Monitoring Network in order to have comparison with the long-term monitoring data currently being collected. Monitoring protocols describe why and how we collect, manage, analyze, and report monitoring data about the network's Vital Signs. The protocols consist of a narrative and associated set of standard operating procedures (SOPs). Monitoring Reports summarize data and findings from our Vital Signs monitoring activities.

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.
