The Del Norte salamander (Plethodon elongatus) is a species of salamander in the family Plethodontidae endemic to the United States in southwestern Oregon and northwestern California. Plethodon elongatus is a medium-sized, slender salamander. Adults are 6–7.5 cm (2.4–3.0 in) from snout to vent, and 11–15 cm (4.3–5.9 in) in total length. Limbs are relatively short; toes are short and slightly webbed. Dorsal coloration is dark brown or black. A reddish or reddish-brown straight-edged mid-dorsal stripe may extend from the head to the tip of the tail; the stripe may be less pronounced in older animals.
P. elongatus is a fully terrestrial salamander. Clutch size is three to 11 eggs (mean eight). No free-living larval stage exists, and juveniles hatch completely metamorphosed, measuring about 18 mm (0.71 in) in snout–vent length.
The species occurs in areas of moist talus and rocky substrates in redwood or Douglas fir forests. It is typically encountered among moss-covered rocks or under bark and other forest litter, usually avoiding very wet areas.
The Del Norte salamander is locally abundant in suitable habitat. It is threatened... Wikipedia →

Likely
About 40% of wildlife watchers report a Del Norte Salamander sighting in Redwood National Park on a given day, based on 399 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 8th most-seen of the 14 amphibians 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.
March
In that month about 60% of wildlife watchers report a Del Norte Salamander in Redwood National Park on a given day, against about 10% in July, the lowest month. That is one of Redwood National Park's wettest months, with about 270 mm of rain against almost none in July.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Del Norte Salamander sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Redwood National Park, in our data
Redwood National Park is the only park on Wallace's Line with enough records to rate Del Norte Salamander sightings: about 40% of wildlife watchers there report one on a given day.
Same family: Plethodontidae
The closest relatives of the Del Norte Salamander that you can see in Redwood National Park (family Plethodontidae, Lungless Salamanders) are Ensatina (about 60%), California Slender Salamander (about 50%) and Wandering Salamander (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Del Norte Salamander is recorded against all the amphibians logged in Redwood National Park (399 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.
