With luck
About 10% of wildlife watchers report a Channel Islands Slender Salamander sighting in Channel Islands National Park on a given day, based on 77 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 3rd most-seen of the 5 amphibians we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
March and April
In those months about 30% of wildlife watchers report a Channel Islands Slender Salamander in Channel Islands National Park on a given day, against under 5% in July to November, the lowest months. Those are among Channel Islands National Park's wettest months, with about 35 mm of rain a month against almost none in July.
Between 11 pm and 2 am
Across all the parks we cover, that three-hour window holds the most Channel Islands Slender Salamander sightings with a recorded time, and about 9 in 10 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 Channel Islands Slender Salamander sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Channel Islands Slender Salamander is recorded against all the amphibians logged in Channel Islands National Park (77 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.
