Howland Island is an uninhabited island located at 0°48′N 176°37′W (revised coordinates based on recent mapping) in the Central Pacific It is a National Wildlife Refuge (NWR) under the USFWS and public access is by permit only; most permits are issued to scientists and educators. The United States took possession of the island in 1856 under the Guano Islands Act of 1856 and from 1886 to 1934 it was a British Overseas Territory. Guano mining was conducted in the last half of the 1800s until guano stocks were depleted. There was a brief attempt at colonization at Howland, Jarvis, and Baker Islands from 1935 to 1942 by students and alumnae from Kamehameha School in Hawai‘i.
