Pacific Flyway
The Pacific Flyway is a major north-south flyway for migratory birds in the Americas, extending from Alaska to Patagonia. Every year, migratory birds travel some or all of this distance both in spring and in fall, following food sources, heading to breeding grounds, or travelling to overwintering sites. Any given bird species travels roughly the same route every year, at almost the same time. Ornithologists and birdwatchers can often predict to the day when a particular species will show up in their area. Notable locations Along the Pacific Flyway, there are many key rest stops where birds of many species gather, sometimes in the millions, to feed and regain their strength before continuing. Some species may remain in these rest stops for the entire season, but most stay a few days before moving on. :''Notable locations include:'' * Boundary Bay, British Columbia, has been listed as an Important Bird Area by the Canadian government in recognition of its value to migratory bi ...

Richmond, British Columbia
Richmond is a coastal city in the Lower Mainland region of British Columbia, Canada. It occupies almost the entirety of Lulu Island (excluding Queensborough), between the two estuarine distributaries of the Fraser River. Encompassing the adjacent Sea Island (where the Vancouver International Airport is located) and several other smaller islands and uninhabited islets to its north and south, it neighbours Vancouver and Burnaby on the Burrard Peninsula to the north, New Westminster and Annacis Island to the east, Delta to the south, and the Strait of Georgia to the west. The Coast Salish peoples were the first people to inhabit the area of Richmond, with the Musqueam Band naming the site near Terra Nova "spələkʷəqs" or "boiling point". As a member municipality of Metro Vancouver, Richmond is composed of eight local neighbourhoods: Sea Island, City Centre, Thompson, West Richmond, Steveston, South Arm, East Richmond and Hamilton. As of 2022, the city has an estimated pop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Basin
The Great Basin is the largest area of contiguous endorheic basin, endorheic watersheds, those with no outlets, in North America. It spans nearly all of Nevada, much of Utah, and portions of California, Idaho, Oregon, Wyoming, and Baja California. It is noted for both its arid climate and the basin and range topography that varies from the North American low point at Badwater Basin in Death Valley to the highest point of the contiguous United States, less than away at the summit of Mount Whitney. The region spans several physical geography, physiographic divisions, biomes, ecoregions, and deserts. Definition The term "Great Basin" is applied to hydrography, hydrographic, ecology, biological, floristic province, floristic, physiographic, topography, topographic, and Ethnography, ethnographic geographic areas. The name was originally coined by John C. Frémont, who, based on information gleaned from Joseph R. Walker as well as his own travels, recognized the hydrographic nature o ...

Great Salt Lake
The Great Salt Lake is the largest saltwater lake in the Western Hemisphere and the eighth-largest terminal lake in the world. It lies in the northern part of the U.S. state of Utah and has a substantial impact upon the local climate, particularly through lake-effect snow. It is a remnant of Lake Bonneville, a prehistoric body of water that covered much of western Utah. The area of the lake can fluctuate substantially due to its low average depth of . In the 1980s, it reached a historic high of , and the West Desert Pumping Project was established to mitigate flooding by pumping water from the lake into the nearby desert. In 2021, after years of sustained drought and increased water diversion upstream of the lake, it fell to its lowest recorded area at 950 square miles (2,460 km²), falling below the previous low set in 1963. Continued shrinkage could turn the lake into a bowl of toxic dust, poisoning the air around Salt Lake City. The lake's three major tributaries, the ...

Coyote Valley, California
Coyote Valley is an area located in a narrowing of the southern Santa Clara Valley, in Northern California. Coyote Valley is approximately in size and largely composed of farmland, orchards, open space preserves, and homes. Coyote Valley is generally divided into three sections: North Coyote Valley (which is part of San Jose), the unincorporated village of Coyote, California (which is located in North Coyote Valley), and South Coyote Valley (which is part of Morgan Hill). Coyote Valley is one of the largest greenbelts in the San Francisco Bay Area. Much of Coyote Valley is preserved as open space, nature reserve, or protected farmland. The area was threatened by large-scale development in the early 2000s, which drew criticism from the public, resulting in the abandonment of the redevelopment plans and the establishment of the conservation policy which governs the valley. The Coyote Gap at the extreme north end of Coyote Valley is a critical wildlife corridor for safe passage o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Francisco Bay
San Francisco Bay is a large tidal estuary in the U.S. state of California, and gives its name to the San Francisco Bay Area. It is dominated by the big cities of San Francisco, San Jose, and Oakland. San Francisco Bay drains water from approximately 40 percent of California. Water from the Sacramento and San Joaquin rivers, and from the Sierra Nevada mountains, flow into Suisun Bay, which then travels through the Carquinez Strait to meet with the Napa River at the entrance to San Pablo Bay, which connects at its south end to San Francisco Bay. It then connects to the Pacific Ocean via the Golden Gate strait. However, this entire group of interconnected bays is often called the ''San Francisco Bay''. The bay was designated a Ramsar Wetland of International Importance on February 2, 2017. Size The bay covers somewhere between , depending on which sub-bays (such as San Pablo Bay), estuaries, wetlands, and so on are included in the measurement. The main part of the bay meas ...

Sacramento–San Joaquin River Delta
The Sacramento–San Joaquin River Delta, or California Delta, is an expansive inland river delta and estuary in Northern California. The Delta is formed at the western edge of the Central Valley by the confluence of the Sacramento and San Joaquin rivers and lies just east of where the rivers enter Suisun Bay, which flows into San Francisco Bay and then the Pacific Ocean via San Pablo Bay. The Delta is recognized for protection by the California Bays and Estuaries Policy. Sacramento–San Joaquin Delta was designated a National Heritage Area on March 12, 2019. The city of Stockton is located on the San Joaquin River on the eastern edge of the delta. The total area of the Delta, including both land and water, is about . Its population is around 500,000 residents. The Delta was formed by the raising of sea level following glaciation, leading to the accumulation of Sacramento and San Joaquin River sediments behind the Carquinez Strait, the sole outlet from the Central Valley ...

Inverted River Delta
{{noref, date=July 2008 An inverted river delta is special category of river delta in which the narrow end of the delta emerges on the seafront and the wide end is located further inland, so that with respect to the seafront, the locations of both ends of the delta are inverted. Explanation River deltas typically form on flat, coastal floodplains: the narrow end located at the point where a river fans out and deposits sediment in a region extending outward into the body of water which the river empties. In the case of an inverted delta, the delta is located at the waterway's exit from a large, flat valley, yet still inside the valley. The sediment is dropped within the valley and the clear water then exits into a bay or the ocean, so the apex of the delta is at this exit, a configuration said to be inverted from that usually seen. Inverted deltas typically do not last long in geological terms, since they tend to fill up with sediments rather quickly and eventually become normal ...

Suisun Marsh
Located in northern California, the Suisun Marsh ( ) has been referred to as the largest brackish water marsh on west coast of the United States of America. The marsh land is part of the San Francisco Bay tidal estuary, and subject to tidal ebb and flood. The marsh is home to many species of birds and other wildlife, and is formed by the confluence of the Sacramento and San Joaquin rivers between Martinez and Suisun City, California and several other smaller, local watersheds. Adjacent to Suisun Bay, the marsh is immediately west of the legally defined Sacramento-San Joaquin Delta as well as part of the San Francisco Bay estuary. The Suisun Marsh is named for the Suisunes, a Patwin/Wintun sub-tribe, who inhabited the area around 200 years ago. Overview Suisun Marsh, 116,000 acres (470 km2) of land, bays, and sloughs, is one of the largest estuarine marshes in the western United States. Geologically, the Suisun Marsh is the product of water-borne sediment deposition, carri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sacramento National Wildlife Refuge Complex
The Sacramento National Wildlife Refuge Complex is part of the United States system of National Wildlife Refuges (NWR). It is located in northern California, in the valley of the Sacramento River. The Sacramento NWR Complex was created in an attempt to resolve the conflict between the needs of migrating birds using the Pacific Flyway, and those of agriculture. The Sacramento NWR Complex headquarters and visitor center is located in the 10,819-acre Sacramento National Wildlife Refuge off of 99W, and features a wildlife exhibit, bookstore, and Discovery Room. Visitors can enjoy a six-mile auto tour with 3 viewing areas and two walking trails. History and components Before the arrival of European settlers in the 19th century, much of the Sacramento valley was taken up by seasonal wetlands and grasslands. By the beginning of the 20th century, much of this had been replaced by farmland, particularly for the growing of rice, and the rivers no longer create new wetlands because their ...
