Many authorities have accepted research concluding that the island fence lizard (Sceloporus occidentalis becki) is its own unique species. However, there is some discrepancy between the current classification of the species and emerging findings, thus the taxonomy of the entire Sceloporus occidentalis species could be revised in the future.

Likely
About 40% of wildlife watchers report an Island Fence Lizard sighting in Channel Islands National Park on a given day, based on 231 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 2nd most-seen of the 9 reptiles we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
April and May
In those months about 60% of wildlife watchers report an Island Fence Lizard in Channel Islands National Park on a given day, against under 5% in January, the lowest month. Those are among Channel Islands National Park's driest months, with about 5 mm of rain a month against 60 mm in January.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Island Fence Lizard sightings with a recorded time, and nearly all of them come between 6 pm and 6 am: it is mostly seen at night.
Only Channel Islands National Park, in our data
Channel Islands National Park is the only park on Wallace's Line with enough records to rate Island Fence Lizard sightings: about 40% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Island Fence Lizard is recorded against all the reptiles logged in Channel Islands National Park (231 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
