Kodiak Bear

== Description ==
The Kodiak bear (Ursus arctos middendorffi ), also known as the Kodiak brown bear, sometimes the Alaskan brown bear, inhabits the islands of the Kodiak Archipelago in southwest Alaska. It is the largest recognized subspecies or population of the brown bear, and one of the two largest bears alive today, the other being the polar bear.
== Appearance ==
Hair colors range from blonde to orange (typically females or bears from southern parts of the archipelago) to dark brown. Cubs often retain a white "natal ring" around their neck for the first few years of life. The Kodiak bear's color is similar to that of its close relatives, the mainland American and Eurasian brown bears.
== Distribution ==
This brown bear population only occurs on the islands of the Kodiak Archipelago (Kodiak, Afognak, Shuyak, Raspberry, Uganik, Sitkalidak, and adjacent islands). The Kodiak bear population was estimated to include 3,526 bears in 2005, yielding an estimated archipelago-wide population density of 270 bears per 1000 km2 (700 per 1000 sq.mi). During the past decade the population has been slowly increasing.
== Lifestyle ==
Kodiak bears begin entering their dens in late October. Pregnant sows are usually the first to go to dens; males are the last. Males begin emerging from their dens in early April, while sows with new cubs may stay in dens until late June. Bears living on the north end of Kodiak Island tend to have longer denning periods than bears in the southern areas. Most Kodiak bears dig their dens in hill or mountain sides and they use a wide variety of denning habitats depending on which part of the archipelago they live. Almost a quarter of the adult bears forgo denning, staying somewhat active throughout the winter.
== Reproduction ==
Kodiak bears reach sexual maturity at age five, but most sows are over nine years old when they successfully wean their first litter. The average time between litters is four years. Sows continue to produce cubs throughout their lives, but their productivity diminishes after they are 20 years old. Mating season for Kodiak bears is during May and June. They are serially monogamous (having one partner at a time), staying together from two days to two weeks. As soon as the egg is fertilized and divides a few times, it enters a state of suspended animation until autumn when it finally implants on the uterine wall and begins to grow again. Cubs are born in the den during January or February. Weighing less than 450 g (1 lb) at birth with little hair and closed eyes, they suckle for several months, emerging from the den in May or June, weighing 6.8–9.1 kilograms (15–20 pounds). Typical litter sizes on Kodiak are two or three cubs, with a long-term average of 2.4 cubs per litter. However, Kodiak bears have six functional nipples and litters up to six cubs have been reported. Sows are sometimes seen with five or six cubs in tow, probably due to adopting cubs from other litters. Most cubs stay with their mothers for three years. Almost half of the cubs die before they leave, with cannibalism by adult males being one of the major causes of death.

=== Population number ===
In 1971, the Alaska Native Claims Settlement Act (ANCSA) resolved many long-standing land issues with aboriginal Alaskans statewide. The impacts were felt strongly on the archipelago as large areas were conveyed to the Native corporations. Federal management of the National Forest lands on Afognak was transferred to Native Corporation ownership with passage of the Alaska National Interest Lands Conservation Act in 1980 (ANILCA), and the Kodiak National Wildlife Refuge lost control of 130,000 hectares (310,000 acres) of prime bear habitat (more than 17% of refuge lands).

=== Kodiak Archipelago Bear Conservation and Management Plan ===
In 2001, a citizens advisory committee was established to work closely with the Alaska Department of Fish and Game (ADF&G), with the cooperation of Kodiak NWR, to develop a management plan addressing several problems that affect bears, including hunting, habitat, and viewing. The resulting Kodiak Archipelago Bear Conservation and Management Plan was crafted over several months by representatives from 12 diverse user groups, which, after hearing from a variety of experts from agencies and receiving extensive public input, developed more than 270 recommendations for managing and conserving Kodiak bears. Despite the diversity of viewpoints expressed by members of the group, all of the recommendations were by consensus.
