The Iberian emerald lizard (Lacerta schreiberi), also known commonly as Schreiber's green lizard, is a species of lizard in the family Lacertidae. The species is endemic to the Iberian Peninsula. It is known as Lagarto-de-água (water lizard) in Portuguese and lagarto verdinegro (green and black lizard) in Spanish.
Lacerta schreiberi is found in Portugal and Spain. The natural habitats of L. schreiberi are temperate forests and shrublands, Mediterranean-type shrubby vegetation, rivers, and pastureland. Lacerta schreiberi is threatened by habitat loss.
A large species, L. schreiberi measures about 13.5 cm (5.3 in) snout-to-vent (SVL); including the tail, it measures about 38 cm (15 in). Lacerta schreiberi is mainly insectivorous, though it also preys on small lizards like the iberian wall lizard or large psammodromus.
Lacerta schreiberi is oviparous. Clutch size varies from 11 to 28 eggs. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Iberian Emerald Lizard is recorded against all the reptiles logged in Sierra de Guadarrama National Park (88 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.
