Transboundary Watershed Region
The Transboundary Watershed Region is a region of northwest British Columbia and southeast Alaska that includes the Tatshenshini River, Tatshenshini-Alsek River, Alsek, Chilkat River, Chilkat, Chilkoot River, Chilkoot, Skagway, Taiya, Taku, Iskut-Stikine, Unuk, and Whiting watersheds. The region extends from high alpine tundra, through boreal landscapes and coastal rainforests, to the island marine environment of southeast Alaska, covering over . The land and rivers within these watersheds support populations of wildlife including: grizzly and black bears, moose, caribou, mountain goats, sheep, wolves, and rare bird migration, migratory birds. The major rivers of the region are abundant with wild Pacific salmon. The "Transboundary Watershed Region" remains home to the Tlingit, Tahltan, Haida, Champagne-Aishihik and Carcross-Tagish First Nations, among others.

British Columbia
British Columbia (commonly abbreviated as BC) is the westernmost Provinces and territories of Canada, province of Canada, situated between the Pacific Ocean and the Rocky Mountains. It has a diverse geography, with rugged landscapes that include rocky coastlines, sandy beaches, forests, lakes, mountains, inland deserts and grassy plains, and borders the province of Alberta to the east and the Yukon and Northwest Territories to the north.

Alaska
Alaska ( ; russian: Аляска, Alyaska; ale, Alax̂sxax̂; ; ems, Alas'kaaq; Yup'ik: ''Alaskaq''; tli, Anáaski) is a state located in the Western United States on the northwest extremity of North America. A semi-exclave of the U.S., it borders the Canadian province of British Columbia and the Yukon territory to the east; it also shares a maritime border with the Russian Federation's Chukotka Autonomous Okrug to the west, just across the Bering Strait. To the north are the Chukchi and Beaufort Seas of the Arctic Ocean, while the Pacific Ocean lies to the south and southwest. Alaska is by far the largest U.S. state by area, comprising more total area than the next three largest states ( Texas, California, and Montana) combined. It represents the seventh-largest subnational division in the world. It is the third-least populous and the most sparsely populated state, but by far the continent's most populous territory located mostly north of the 60th paralle ...

Tatshenshini River
The Tatshenshini River (; Tlingit ''Tʼachanshahéeni'', Southern Tutchone ''Shäwshe Chù'') is a river in the Canadian boreal forest, in the southwestern Yukon and the northwestern corner of British Columbia. It originates in British Columbia, near Haines Highway. It flows north into Yukon, then it turns west and south before it returns into British Columbia, where it flows through the Tatshenshini-Alsek Provincial Wilderness Park. There it joins the Alsek River, which then flows into the Pacific Ocean in Alaska, United States. It is popular for wilderness rafting trips. History This river was used as a vital trade route by First Nations, in particular the coastal Tlingit people. The first Europeans to travel the present-day Tatshenshini River were Jack Dalton and Edward Glave in 1890, accompanied by two native guides. Prior to 1891, the present-day Tatshenshini River was considered to be the upper Alsek River., at pp. 15, 18-19 (“All-segh'”; “Katch-kwae-wugh”; “Ta-tc ...

Alsek River
The Alsek River (; Tlingit ''Aalseix̱' '') is a wilderness river flowing from Yukon into Northern British Columbia and into Alaska. It enters the Gulf of Alaska at Dry Bay. Most of the Alsek River's basin is within protected wilderness areas and National Parks. The Alsek and its main tributary, the Tatshenshini River, are part of the Canadian Heritage Rivers System and a UNESCO World Heritage Site. In the year 2016, the Alsek River captured the flow of the Slims River due to the retreat of Kaskawulsh Glacier. Researchers attributed the change in flow to human-caused climate change; this was the first time human-caused climate change was implicated in the reorganization of a river. Research indicates that in a few decades, Alsek River may further change its final course. The rapidly retreating Grand Plateau Glacier separates Alsek River and lake from nearby Grand Plateau Lake. Geologists predict that when the two lakes merge, Alsek River will abandon its current outlet in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chilkat River
The Chilkat River is a river in British Columbia and southeastern Alaska that flows southward from the Coast Range to the Chilkat Inlet and ultimately Lynn Canal. It is about long. It begins at Chilkat Glacier, in Alaska, flows west and south in British Columbia for , enters Alaska and continues southwest for another . It reaches the ocean at the abandoned area of Wells, Alaska and deposits into a long delta area. The river was named by the Russians for the Chilkat group of Tlingit, called /t͡ʃiɬqut/ in their own language, who lived in the region. The name means "salmon storehouse". Near the Chilkat River is the Alaska Chilkat Bald Eagle Preserve, where thousands of bald eagles appear between October and February, to take advantage of late salmon runs. Nearby Haines, the nearest town, is the most common organization spot for birdwatchers.

Chilkoot River
The Chilkoot River is a river in Southeast Alaska, United States, that extends about from its source and covers a watershed area of . The source of the river is in the Takshanuk Mountains to the west and the Freebee glacier and unnamed mountains to the east. From its source, the upper reach of the river extends approximately to the point where it enters Chilkoot Lake. From the downstream end of the lake, the lower reach of the river flows for about until it enters the Chilkoot Inlet, a branch at the northern end of the Lynn Canal. At the head of the lower reach of the river, on the shore of the lake, lies a prehistoric village which was a Chilkoot Indian settlement. The names of the village — Tschilkut, Tananel, or Chilcoot — have been given to the river and also to the lake. The river and its precincts, known as the Chilkoot River Corridor, have been brought under the monitoring of the Chilkoot River Corridor Strategic Planning Project (CRC) to preserve its ec ...

Alpine Tundra
Alpine tundra is a type of natural region or biome that does not contain trees because it is at high elevation, with an associated harsh climate. As the latitude of a location approaches the poles, the threshold elevation for alpine tundra gets lower until it reaches sea level, and alpine tundra merges with polar tundra. The high elevation causes an adverse climate, which is too cold and windy to support tree growth. Alpine tundra transitions to sub-alpine forests below the tree line; stunted forests occurring at the forest-tundra ecotone are known as ''Krummholz''. With increasing elevation it ends at the snow line where snow and ice persist through summer. Alpine tundra occurs in mountains worldwide. The flora of the alpine tundra is characterized by dwarf shrubs close to the ground. The cold climate of the alpine tundra is caused by adiabatic cooling of air, and is similar to polar climate. Geography Alpine tundra occurs at high enough altitude at any latitude. Portion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Migration
Bird migration is the regular seasonal movement, often north and south along a flyway, between breeding and wintering grounds. Many species of bird migrate. Migration carries high costs in predation and mortality, including from hunting by humans, and is driven primarily by the availability of food. It occurs mainly in the northern hemisphere, where birds are funneled onto specific routes by natural barriers such as the Mediterranean Sea or the Caribbean Sea. Migration of species such as storks, turtle doves, and swallows was recorded as many as 3,000 years ago by Ancient Greek authors, including Homer and Aristotle, and in the Book of Job. More recently, Johannes Leche began recording dates of arrivals of spring migrants in Finland in 1749, and modern scientific studies have used techniques including bird ringing and satellite tracking to trace migrants. Threats to migratory birds have grown with habitat destruction, especially of stopover and wintering sites, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
