Yet the giant salamander is on the path to extinction, a trend that North Carolina State University researchers are working to understand to help inform future management decisions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cWe know the Neuse River waterdog has experienced significant population declines across its range, but we still don\u2019t fully know how to protect this species.

The species, though still fairly common in some of these places, has suffered up to 50% declines in some areas across its range. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Neuse River waterdog is currently listed as a \u201cspecies of special concern\u201d by the North Carolina Wildlife Resources Commission, meaning it cannot be legally killed, collected or possessed without a special permit.\u00a0The U.S. Fish and Wildlife Service has proposed to list the Neuse River waterdog as \u201cthreatened\u201d under the Endangered Species Act.

Photo provided by Ben Zino\/NC State University<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Teitsworth said the species&#8217; decline is likely a result of watershed instability and water pollution caused by increased rates of urban development. North Carolina is experiencing rapid growth that has brought housing development and road construction, both of which can negatively impact water quality in nearby streams and rivers.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cWaterdogs prefer clean water that\u2019s always flowing, and they\u2019re very sensitive to change,\u201d Teitsworth said. \u201cWhen you have high rates of urban development, you get a lot of impervious surfaces that can increase the amount of water entering a stream after a storm. That can not only lead to increased variability in streamflow, but it can also cause increased sediment input that washes down and degrades habitat.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Teitsworth added that large quantities of nutrient pollution, especially phosphorus and nitrogen, can also harm Neuse River waterdog populations. This type of pollution results from fertilizers and animal waste that\u2019s washed from lawns, urban developed areas, farm fields and industrial meat production facilities into streams and rivers.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">While some of the same nutrients can be beneficial to aquatic life in small amounts, too many nutrients can contribute to excessive plant growth, algae blooms and low levels of dissolved oxygen in the water. The Neuse River waterdog and other aquatic animals need dissolved oxygen to survive.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Teitsworth said riparian buffers, wetland remediation and other measures can help address sediment erosion and nutrient pollution. His research will ultimately help state and federal wildlife management agencies better understand where those measures might be most effective as they seek to help the Neuse river waterdog achieve healthy, self-sustaining populations.<\/p>\n","protected":false,"raw":"<!-- wp:ncst\/dynamic-header {\"block\":\"ncst\/default-immersive-post-header\"} -->\n<!-- wp:ncst\/default-immersive-post-header {\"backgroundColor\":\"custombg_four\",\"caption\":\"During the spring, Neuse River waterdogs move to large bedrock outcrops or beneath large boulders.
