IUCN
Red List
Although
there is insufficient information on the distribution,
population (and its trends), and biology of Gagata
gagata, it is inferred to have a wide distribution;
hence Least Concern.
Data to verify its supposed decline since the 1800s
is badly needed, and needs updating, (IUCN 2010).
