Taxonomic Notes: Some workers have suggested that Paradactylodon gorganensis might be conspecific with P. persicus (Stöck 1999). However, recent molecular analysis has demonstrated that Paradactylodon gorganensis is a distinct species (Ted Papenfuss pers. comm. September 2008).

Population [top]

Population:There are estimated to be about 100 breeding adults within its extremely localized range.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It is an almost fully aquatic species. The adults are only known from a single pool in the cave that measures 100m by 10m at its widest point. The larvae of the species are only found outside the cave in the stream flowing from it. Its breeding biology is not well known, but eggs are deposited by the female and fertilized by the male. The forest surrounding the cave and stream is a temperate Hyrcanian forest.

Threats [top]

Major Threat(s): The Shir-Abad Cave is now significantly impacted by the activities of people visiting the cave (N. Rastegar-Pouyani pers. comm.). However, the forest surrounding both the cave and stream does not appear to have been logged, since the area is generally considered to be too rugged for development. Collection for the pet trade is a potential though not confirmed threat to this species (Mozafar Sharifi pers. comm. September 2008).

Conservation Actions [top]

Conservation Actions: Nearly all the Hyrcanian forests of Iran are conserved within protected areas, including the range of this species (N. Rastegar-Pouyani pers. comm.). Shir-Abad Cave and the surrounding area was designated a Natural National Monument by the Department of Environment of Gorgan and Gonbad-e-Kavous in 1998.
