Manchurian Mixed Forests
The Manchurian mixed forests ecoregion (WWF ID: PA0426) covers the forested hills surrounding the river plains of northern China, Russia, North Korea, and South Korea. The ecoregion supports a number of rare species due to the relative isolation, the diversity of habitat, with mixed forests of deciduous Mongolian oak and conifers of Korean pine. Because mountains rise above the region on three sides, with plains and wetlands below, the area supports high biodiversity as a transition zone. Location and description The ecoregion occupies the middle-elevation slopes of three surrounding mountain ranges: the eastern slopes of the Greater Khingan Mountains, the southern slopes of the Lesser Khingan, and the western slopes of the Changbai Mountains. The southern section of the ecoregion surrounds the higher Changbai Mountains mixed forests ecoregion, while the middle section encircles most of the lower-elevation Northeast China Plain deciduous forests ecoregion, and the northern hal ...

Palearctic Realm
The Palearctic or Palaearctic is the largest of the eight biogeographic realms of the Earth. It stretches across all of Eurasia north of the foothills of the Himalayas, and North Africa. The realm consists of several bioregions: the Euro-Siberian region; the Mediterranean Basin; the Sahara and Arabian Deserts; and Western, Central and East Asia. The Palaearctic realm also has numerous rivers and lakes, forming several freshwater ecoregions. The term 'Palearctic' was first used in the 19th century, and is still in use as the basis for zoogeographic classification. History In an 1858 paper for the ''Proceedings of the Linnean Society'', British zoologist Philip Sclater first identified six terrestrial zoogeographic realms of the world: Palaearctic, Aethiopian/Afrotropic, Indian/Indomalayan, Australasian, Nearctic, and Neotropical. The six indicated general groupings of fauna, based on shared biogeography and large-scale geographic barriers to migration. Alfred Wallace ad ...

Land Of The Leopard National Park
Land of the Leopard National Park is a national park in Primorsky Krai in the Russian Far East, covering an area of west of Razdolnaya River. It was gazetted in April 2012. It was established to protect the Amur leopard which was at the time the world's rarest cat with an estimated population of 30 individuals. The park was created from the merger of Kedrovaya Pad Nature Reserve, Barsovy Federal Wildlife Refuge and Borisovkoye Plateau Regional Wildlife Refuge, and a new territory along the border with China. History By the beginning of the 21st century the Amur leopard population was on the verge of extinction. As a result of poaching and fires, the vast habitat of the beast had shrunk to a narrow stripe in the southwest of Primorsky Krai. By then, a Kedrovaya Pad nature reserve and several breeding grounds existed here, but only expansion of the protected area and integrated management of the existing natural territories could solve the problem of conserving the rare cat.

Protected Area
Protected areas or conservation areas are locations which receive protection because of their recognized natural, ecological or cultural values. There are several kinds of protected areas, which vary by level of protection depending on the enabling laws of each country or the regulations of the international organizations involved. Generally speaking though, protected areas are understood to be those in which human presence or at least the exploitation of natural resources (e.g. firewood, non-timber forest products, water, ...) is limited. The term "protected area" also includes marine protected areas, the boundaries of which will include some area of ocean, and transboundary protected areas that overlap multiple countries which remove the borders inside the area for conservation and economic purposes. There are over 161,000 protected areas in the world (as of October 2010) with more added daily, representing between 10 and 15 percent of the world's land surface area. As of 20 ...

Pinus Sylvestris
''Pinus sylvestris'', the Scots pine (UK), Scotch pine (US) or Baltic pine, is a species of tree in the pine family Pinaceae that is native to Eurasia. It can readily be identified by its combination of fairly short, blue-green leaves and orange-red bark. Description ''Pinus sylvestris'' is an evergreen coniferous tree growing up to in height and in trunk diameter when mature, exceptionally over tall and in trunk diameter on very productive sites. The tallest on record is a tree over 210 years old tree growing in Estonia which stands at .
