Nayyereh Pour-Molaee further said the measure was conducted with the aim of estimating the species population, habitat conservation and improvement in environmental management of Gando habitats.
She said that the census was conducted directly and round the clock.
The largest population of this species is mostly found in Sarbaz River route and Shirgowaz diversion dam. In addition, some of them inhabit ponds and floodgates along the Kajoo River, Pour-Molaee added.
She said short-snout crocodile, or marsh crocodile, is among national asset and an endangered species.
The environmentalist also added that these crocodiles were placed in vulnerable group based on the latest global ranking for conservation of nature in 2015.
Given the local conditions and a drop in precipitation, Pour-Molaee underlined the need to improve their biotic conditions.
Gandos are among timid creatures which hardly ever appear. They are usually around four to five meters in length and their main foods are mostly fish, turtles, vultures and aquatic birds.
