The cool and beautiful mixed forests of the Asian mountains - comfortable and great for birding!
This section covers different vegetation communities. While there are various mountains and ranges across tropical Asia, a long swathe of subtropical/temperate forests are at their easiest to see in the lower Himalayas, particularly in tourist accessible countries such as India, Nepal and Bhutan.
The lowland 'jungle' of tropical Asia transitions into cooler but almost as diverse subtropical & temperate forest as altitude increases quickly in northern India, Nepal and Bhutan. The higher altitude forest is often dominated by Oaks, and is interspersed with conifers, thus these mixed forests and woodlands are known as 'Oak & Pine' forests. In wetter valleys and slopes, the dominant trees here are relatives of more familiar and widespread northern hemisphere species, including Quercus Oak, Acer Maple, Betula Birch, Magnolia, and various conifers. But there are also patches of more East Asian elements, such as Bamboo and Rhododendron.
This temperate & subtropical rainforest continues with similar species into the lowlands of the northern Indo-Malay area, including northern Vietnam and mostly southern China. (There is also highland rainforest found in elevated areas around tropical south-east Asia, but this has different series of and distinct plant and animal species.)
In slightly drier adjacent areas are patches of 'Chir Pine' Pinus roxburghii. These forests are often on the slopes of valleys opposite the wetter closed forests, and are depressingly sparse in both plant and animal diversity. Other conifer-dominated vegetation communities include the species poor Pinus wallichiana 'Blue/Himalayan Pine' forests. Higher up we get mixed Picea 'Spruce', Tsuga dumosa 'Himalayan Hemlock' and the beautiful Abies densa 'Bhutan Fir'.
Above this forest, we start to get past the tree line, and these exposed areas host alpine meadows and then relatively barren rocky slopes. This is another biome that may be best considered in the PALEARCTIC region, but I haven't written that yet.
The genus of conifers Abies, the 'Firs', contains some 50 or so species. They usually grow as tall trees. Firs can be distinguished from other conifers by the way each single needle-like leaf is attached to the branch with a rounded base. The cones usually stand upright like candles, and then start to fall apart once mature. They are mostly found in mountain forests, and are distributed across Asia, Europe, Africa and North & Central America. Below is Abies densa, the 'Bhutan/Sikkim Fir'. It is most common at 3000 to 4000 metres altitude, in the Himalayan region.
While we might think of Maples (Acer spp.) as Canadian, they are in fact spread across the northern hemisphere, and most species are found in temperate Asia.
And there is a nice range of flowers in the understory and on the edge of the forest...
Being cooler forests due to the higher altitudes means there are generally less insects, frogs and reptiles. However, in spring and summer the flowers need pollinators, and so there are some butterflies to be seen...
Although many people think of pheasants (family Phasianidae) being found all over the world, these are mostly introduced. The peak of their diversity is in the higher altitude forests of Asia. They are strongly sexually dimorphic, with the males being larger and famous for their bright colours and elaborate tails.
The 'Speckled Wood Pigeon' Columba hodgsonii, is found in montane forests around the Himalayan region, across the northern part of the south-east Asian mainland, and into China.
The family Corvidae includes various species found in these habitats, including the 'Spotted Nutcracker', Nucifraga caryocatactes, a subspecies of the more widespread Eurasian Nutcracker, and equally reliant on Pinus cones.
The family also includes the ' Yellow-billed/Golden-billed Blue Magpie', Urocissa flavirostris.
The higher altitude and cooler temperatures, as well as position on the edge of the Indo-Malayan and Palearctic biogeographical regions, results in groups of species that are much more Eurasian or even Holarctic in character. Such groups include the 'Tits' of the family Paridae. Below is Parus monticolus, the 'Green-backed Tit', mostly associated with mountain forests throughout northern mainland Asia.
There are lots of endemic smaller birds from obscure groups to look for, such as Cettia brunnifrons, the 'Grey-sided Bush warbler', from the family Cettiidae, the Cettid Bush Warblers.
The family Zosteropidae contains the White-eyes but also includes one of the more obvious and distinct groups of small birds found in these forests; the cute crested 'Yuhinas'.
And then there is the taxonomically confusing mess that includes many of the birds found in these cooler often higher altitude forests, including groups and species such as Parrotbills, Ground Babblers, Tree Babblers, Alcippe Fulvettas, Paradoxornithidae Fulvettas and all the Laughing Thrushes
And in as in the higher altitude forests of the Neotropics and Australasia, some of the prettiest birds are found in these cooler mountain forests, including some stunning species of sunbirds...
The mammals that are common in the lower altitude forests of Asia, such as primates, are less common as you climb in height, but there are some species here, including the 'Himalayan/Nepal Grey Langur'.
The 'Pika' of the family Ochotonidae are mammals that look like tiny rabbits with short ears. They tend to live in high mountain or cooler habitats, mostly across Eurasia, but also into North America.
In Bhutan, there is: Jigme Dorji National Park, and Lampelri Gardens.
