Why conduct a five-year review of federally-listed species ?
A3: Research, monitoring programs and conservation actions have been carried out and are ongoing by Federal and non-Federal (State, private, tribal) entities. As a result, new information is constantly becoming available. Although this information has been made public since the time of listing and the Service has continued to use the best available information under its Endangered Species Act (ESA) responsibilities, the ESA requires this information be fully evaluated at least every five-years.
