Possible
About 30% of wildlife watchers report a Spiny Lava Lizard sighting in El Impenetrable National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 6th most-seen of the 8 reptiles we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
February
In that month about 60% of wildlife watchers report a Spiny Lava Lizard in El Impenetrable National Park on a given day, against under 5% in June–August and December, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Spiny Lava Lizard sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only El Impenetrable National Park, in our data
El Impenetrable National Park is the only park on Wallace's Line with enough records to rate Spiny Lava Lizard sightings: about 30% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Spiny Lava Lizard is recorded against all the reptiles logged in El Impenetrable National Park (7 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.
