caption_attribution_description: English: Boundaries of Anyuysky Park, between the Amur River (to the west), and the Central Sihkote-Alin Mountains
context_page_description: Anyuysky National Park, covers the basin of the Anyuy River, on the west slope of the Central Sikhote-Alin Mountain range in the Russian Far East. The Anyuy flows west into the Amur River, the main river of the region, as it flows northeast into the Sea of Okhotsk. The park is important because it creates an ecological corridor from the low floodplain of the Amur, to the high forested mountains of the Sikhote-Alin. The park is in the Nanaysky District in Khabarovsk Krai, about 50 miles downstream of the city of Khabarovsk. The area is remote, with few towns and sparse population. The area has historically depended on salmon fishing, logging, and hunting. The local indigenous people are the Nanai people, representing about a quarter of the nearby settlements.
context_section_description: The park's boundaries form a horseshoe-shape that follows the dividing ridges of the small river basins of the Anyuy and Pihtsy rivers, which flow west into the Amur River.   The eastern portion of the territory is mountainous, while the lower western portion is mostly floodplain.  Approximately 45% of the park tree cover is Far Eastern Taiga, 30% is sub-taiga (mid-mountain coniferous forest), 14% is river floodplain and delta, and 11% is marsh.  With one-quarter of its territory being temperate wetland of the Amur-Heilong River Basin, Anyuysky is an important habitat for wetland species and fish in the mountain streams above the Amur.  The southern boundary follows the northern line of the "Three Sisters" dividing range of mountains.  
  The western half of the park is on a low-lying eastern extension of the "Sredneamurskaya plain".  This plain is a flat, boggy depression between the Sikhote-Aline ridge to the east and the Lesser Khingan mountains to the west. These are the alluvial lowlands of the Amur River floodplain, down to 40 meters in altitude.  The southeastern wing of the park is the valley of the Pihtsy river, and is relatively flat.  The northeastern wing is the valley of the Anyuy River and its tributaries, and it has steeper and deeper canyons, and an average altitude of 600 meters.  The ultimate headwaters of the Anyuy is Tordoki Yani, the highest peak in the Sikhote-Alin.

Note the inverted horseshoe shape, with the top near the town of Troitskoye, Khabarovsk Krai on the Amur River, which flows towards the northeast.  The park stretches into the Sihkote-Alin Mountains to the east.  The city of Khabarovsk is at the lower left.
