The colonists brought along with them clothing, plants (called "canoe plants") and livestock and established settlements along the coasts and larger valleys. Upon their arrival, the settlers grew kalo (taro), mai`a (banana), niu (coconut), ulu (breadfruit), and raised pua`a (pork), moa (chicken), and `ilio (poi dog), although these meats were eaten less often than fruits, vegetables, and seafood. Popular condiments included pa'akai (salt), ground kukui nut, limu (seaweed), and ko (sugarcane) which was used as both a sweet and a medicine. In addition to the foods they brought, the settlers also acquired `uala (sweet potato), which has yet to be adequately explained, as the plant originates in South America. A few researchers have argued that the presence of the sweet potato in the ancient Hawaiian diet is evidence of pre-Columbian trans-oceanic contact with the Americas.  The Pacific rat accompanied humans on their journey to Hawai`i. David Burney argues that humans, along with the vertebrate animals they brought with them (pigs, dogs, chickens and rats), caused many native species of birds, plants and large land snails to become extinct in the process of colonization.  Estuaries and streams were adapted into fishponds by early Polynesian settlers, as early as 1500 or more years ago. Packed earth and cut stone were used to create habitat, making ancient Hawaiian aquaculture among the most advanced of the original peoples of the Pacific. A notable example is the Menehune Fishpond dating from at least 1,000 years ago, at Alekoko. At the time of Captain James Cook's arrival, there were at least 360 fishponds producing 2,000,000 pounds (900,000 kg) of fish per year. Over the course of the last millennium, Hawaiians undertook "large-scale canal-fed pond field irrigation" projects for kalo (taro) cultivation.  As soon as they arrived, the new settlers built hale (homes) and heiau (temples). Archaeologists currently believe that the first settlements were on the southern end of the Big Island of Hawai`i and that they quickly extended northwards, along the seacoasts and the easily accessible river valleys. As the population increased, settlements were made further inland. At this time, with the islands being so small, the population was very dense. Before European contact, the population had reached somewhere in the range of 200,000 to 1,000,000 people. After contact with the Europeans, however, the population steeply dropped due to various diseases including smallpox.
