Ziegler's water rat

It was discovered in 2005 by K. Helgen,[2] and later was assessed by Helgen, and A. Allison in 2008.[1] The water rat was named in honor of the deceased Dr. Alan C. Ziegler from the Bishop Museum.[2] It has been rated as data deficient for the purposes of the IUCN redlist because insufficient is known about the creature's population range, threats, and numbers.[1] Only two specimens have ever been recorded by scientists.[1] The water rat may be threatened by logging of its forest habitat but more research is needed to codify this theory.[1] It is also believed it may inhabit the northern slopes of its mountain home but study is needed to determine this as fact.[1]

This species inhabits both terrestrial and freshwater systems. This includes forests, subtropical and tropical moist lowland forests, inland wetlands, permanent watercourses, and artificial terrestrial areas.[1] The animal has only been recorded in Bainyik, located on the south slopes of the Prince Alexander Mountains at an elevation of 200 meters (650 feet).[1] The rat has been found to live in creeks and rivers in low lying tropical rain forests but it may also live in higher elevations.[1]
