It is not considered threatened by the IUCN.

López-Seoane studied multiple specimens collected across northwest Spain and Portugal, but did not designate any as a holotype. Therefore, one of these specimens (an adult female collected in A Coruña, Spain and kept in... Wikipedia →

Possible
About 30% of wildlife watchers report an Iberian Green Frog sighting in Aigüestortes National Park on a given day, based on 13 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 5th most-seen of the 7 amphibians we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
March–April and July
In those months about 40% of wildlife watchers report an Iberian Green Frog in Aigüestortes National Park on a given day, against under 5% in May and September–October, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Iberian Green Frog sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 5
Of the 5 parks where we can rate Iberian Green Frog sightings, Aigüestortes National Park ranks 3rd at about 30%. The best odds are in Monfragüe National Park (Spain, about 50%) and Sierra Nevada National Park (Spain, about 30%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Iberian Green Frog is recorded against all the amphibians logged in Aigüestortes National Park (13 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.
