Mediterranean conifer and mixed forests

The Alps conifer and mixed forests ecoregion follows the Alps mountain range across central Europe, spanning France, Italy, Switzerland, Germany, Liechtenstein, Austria, and Slovenia. Its montane forests are a mix of conifers and broadleaves, with Norway spruce, silver fir, European larch, and mountain pine alongside European beech, and prostrate pine in the outer ranges. The region sits at the transition between the Mediterranean climates of southern Europe and the more humid, temperate Euro-Siberian zone, so its western reaches feel mild Atlantic air while the central area is continental. It is one of the richest places in Europe for plants, holding roughly 4,500 native vascular plant species including about 400 endemics, and the recovered Alpine ibex serves as its flagship species; around 27 percent of the ecoregion lies within protected areas such as Gran Paradiso and Vanoise national parks. For gardeners, several classic alpine ornamental genera are native here, including Campanula, Primula, Saxifraga, and Draba.

The Altai montane forest and forest steppe stretches some 1,500 km along the Altai Mountains across the border region where Russia, Kazakhstan, Mongolia, and China meet, running from the Belukha Range in the northwest to the Gobi-Altai in the southeast. Its hallmark is a mosaic shaped by slope aspect: cooler, wetter north-facing slopes carry dense conifer forests of spruce and larch (including larch-cedar stands), while drier south-facing slopes give way to cold steppe and desert-steppe vegetation dominated by feather grass and Artemisia. The climate is cold and semi-arid, with cool summers and long, dry winters in which temperatures plunge well below freezing and precipitation stays low. Sitting at the crossroads of several ecoregions, altitudes, and climate zones, it harbors high biodiversity and supports a widely dispersed population of the globally threatened snow leopard, with protected areas including the Katun Nature Reserve. For gardeners, its hardy native flora includes ornamental grasses like the feather grass Stipa pennata and prairie junegrass (Koeleria).

The Caledon Conifer Forests cover upland Scotland in the United Kingdom, spanning the Northwest Highlands, the Grampian Mountains, and the Cairngorms, and reaching their highest point at Ben Nevis. The defining vegetation is remnant ancient pine forest dominated by Scots pine, accompanied by downy and silver birch, rowan, juniper, and aspen, with heather, dwarf shrub heath, montane willow scrub, and alpine vegetation on higher ground. The climate is warm-temperate with a strong oceanic influence, colder and drier toward the east, and the oceanic conditions hold the natural tree line to only about 500 to 600 meters. Native woodland survives across just a small fraction of Scotland, and these pinewoods shelter the endemic Scottish crossbill and the flagship western capercaillie, along with red squirrels, Scottish wildcats, and golden eagles. For gardeners, the region is the native home of ornamentally useful hardy genera such as Scots pine, birch, rowan, and juniper.

The Carpathian montane forests sweep across the great arc of the Carpathian Mountains, spanning Romania, the Czech Republic, Poland, Slovakia, and Ukraine, with the largest share lying in Romania. Oak-dominated foothills give way to a montane belt of European beech, silver fir, Norway spruce, and sycamore, while above the timberline mountain pine, dwarf juniper, and green alder form dense thickets that grade into alpine meadows. The climate is temperate and continental, producing moderately cool, humid conditions that vary sharply with elevation. This range is a continental stronghold for large carnivores, holding some of Europe's most viable populations of brown bear, grey wolf, and Eurasian lynx, and it shelters more than a third of all European plant species along with endemics such as the Carpathian newt and Tatra pine vole. For gardeners, the region is also home to native ornamentals including heart-leaf comfrey and alpine saxifrages.

The Da Hinggan-Dzhagdy Mountains conifer forests span the Greater Khingan range of northeast China, across the northern Inner Mongolia Autonomous Region and Heilongjiang Province, extending north across the Amur River into Russia's Amur Oblast. Dahurian larch is the dominant conifer, occupying more than half of the total forest area, joined by pine and spruce, while lower elevations and disturbed sites carry Mongolian oak, birch, poplar, hazel, alder, and elm. The setting is severely continental and subarctic, with short mild summers, a frost-free growing season of only about three months, permafrost in the coldest reaches, and winter temperatures that can fall to around -50 degrees Celsius. The forests are noted for their transitional "Daurian flora," blending Siberian taiga with Manchurian elements across roughly 1,200 vascular plant species, and shelter wildlife such as Siberian musk deer, sable, wolverine, and Amur moose; the cold-adapted Siberian salamander is the flagship species. Conservation here is shaped by fire history, including the catastrophic 1987 blaze that burned over a million hectares, and by protected reserves such as Nora and Zeya.

The East Afghan montane conifer forests form a chain of disjunct woodlands along the border between Afghanistan and Pakistan, reaching from the eastern Hindu Kush through Nuristan and Paktia provinces south to the mountains above Quetta, across roughly 20,128 square kilometers at elevations from about 2,000 to 3,400 meters. Vegetation shifts with altitude: drier lower slopes carry chilgoza pine (Pinus gerardiana) and holm oak, denser mid-elevation stands include Himalayan cedar (Cedrus deodara), Morinda spruce (Picea smithiana), and Bhutan pine (Pinus wallichiana), while juniper woodland dominates the highest, driest reaches above about 3,100 meters. The climate is cold and semi-arid with large seasonal temperature swings and modest annual precipitation. These forests shelter the near-threatened markhor (Pakistan's national animal) as well as snow leopards, and notably hold the Ziarat juniper stand, described as the second-largest of its kind in the world with specimens over 1,500 years old; only about 9 percent of the ecoregion is officially protected, with illegal logging and overgrazing the chief threats. For gardeners, several conifers native here, including deodar cedar and Bhutan pine, are widely grown as ornamentals.
