Geocrinia rosea
Family: Myobatrachidae
Common name: Roseate Frog
Description: This frog is brown on its back, with dark mottling or a dark broad band that starts between the eyes and runs down the spine. This broad band often has a pale edge. The belly is rosy, almost luminous pink with dark brown flecks in populations on the Warren and Deep River drainages but a more apricot colour further east. The arms and legs have dark cross-bars. The throat of the male is dark brown or black. The skin on the back is smooth or slightly tubercular (lumpy), while the belly is smooth. The toes are not fringed.
Size: 25 mm
Habitat: This frog lives in wet karri and jarrah forests. It is often found in shallow depressions under streamside vegetation or in rotting logs in upland situations.
Call: Sounds like a continuous "tk…tk…tk…tk" very similar to Geocrinia lutea. Call available in 
Windows Media or 
Quicktime audio. Recording Copyright © Dale Roberts.
Breeding: Occurs in spring and in summer. Males call from their depressions in the clay or mud next to streams.
Eggs: Are laid in the depression used by calling males.
Tadpoles: Hatch from eggs and complete their development in the jelly from the eggs relying on yolk from the egg with no feeding.
Similar species: This frog can be distinguished from other species of Geocrinia and Crinia by its pink belly colouration.
Conservation Information
Suspected threatening processes
- Inappropriate fire regimes
- Habitat modification (e.g. vegetation clearing, invasive weeds)
Population size: An estimate of the total number of adults present in the species entire range is >50000 individuals. Some factors affecting population size and distribution are known, but 1 or more major factors are unknown.
Population trend in Australia over the past 50 years: Population size stable or suspected to be stable or increasing.
Knowledge of population trend in Australia: Not currently monitored.
Population concentration: Majority concentrates at more than 25 locations. (e.g. the number of sites in which individuals group together either seasonally, such as breeding sites, or they may occupy discrete habitat patches within the broader landscape, such as discrete water bodies or drainage units.)
Ongoing management activities in Australia: None directed primarily at the taxon.
Reproductive potential for recovery: The average number of eggs deposited per adult female per year is 1-50 eggs/female/year. Minimum age at which females are known or suspected to first reproduce is 2-3 years.
Range size in Australia: The size of the geographic area over which the taxon is distributed: 1001-80000 km² (up to 1% area of Australia or about the area of Tasmania).
Distribution trend: Area occupied has declined by < 25%. (This is an estimate of change in the portion of the total range that is occupied or utilised; it may not equal the change in total range.)
Knowledge of distribution in Australia: Distribution is well known and occurrence can be accurately predicted throughout the range.
