Providing Critical Resources - Conservation of Wildlife

Another way to improve the habitat of a threatened species is to determine which resource is limiting the population size and to provide more of that resource. Construction of nest boxes for wood ducks has increased the wood duck population in parts of America. The white-naped crane winters in Japan, but the one area where these large, beautiful birds used to feed has now been built over. In 1985, about 45 birds only appeared in all of Japan. The Japanese, therefore, started feeding the birds at just one location in Kyusu, and more than 700 birds now winter in the area each year.
