Most people choose the Mardi Himal Trek for its mountain views, and they are right to. But the trek also packs a remarkable range of natural habitats into a short distance. In just a few days you climb from subtropical farmland near Pokhara, through temperate forest thick with rhododendron and moss, to an alpine ridge where the trees give way to grass and dwarf shrubs. Each zone has its own plants, birds and animals.
This guide introduces the flora and fauna you are likely to encounter along the trail, explains when and where to look, and suggests how to watch wildlife responsibly. You do not need to be a naturalist to enjoy it; a little knowledge simply makes you notice more.
The Annapurna Conservation Area
The entire Mardi Himal Trek lies inside the Annapurna Conservation Area, Nepal's largest protected area, covering around 7,600 square kilometers. It was established in 1986 with a then-new model in which local communities live within the protected area and share responsibility for managing it. The area spans an extraordinary range of altitudes, from low river valleys to the summits of 8,000-meter peaks, which gives it unusually rich biodiversity.
The conservation area's records list well over a thousand species of flowering plants, around a hundred mammal species and several hundred bird species, among them rare animals such as the snow leopard in its higher, drier northern reaches. On Mardi Himal you will not see all of this, but you will walk through several of its most characteristic habitats. For more background, read our guide to the Annapurna Conservation Area.
Ecological Zones Along the Trail
| Zone | Approximate altitude | Where on the trek | Typical vegetation |
|---|---|---|---|
| Subtropical and farmland | Below about 1,800 m | Pokhara to Kande, Siding | Terraced fields, bamboo, fruit trees, broadleaf trees |
| Lower temperate forest | About 1,800–2,500 m | Australian Camp to Forest Camp | Oak, chestnut, rhododendron, ferns |
| Upper temperate forest | About 2,500–3,200 m | Forest Camp to Badal Danda | Tall rhododendron, oak, moss, lichen, bamboo thickets |
| Subalpine and alpine | Above about 3,200 m | Badal Danda to Base Camp | Grassland, dwarf rhododendron, juniper, alpine flowers |
The changes are gradual, but you will notice them clearly, especially when you step out of the forest onto the open ridge above Low Camp. Our guide to Mardi Himal's ecosystems by altitude explores each zone in more detail.
Rhododendron Forests
The rhododendron is Nepal's national flower, and the Mardi Himal route passes through some of the finest rhododendron forest in the Annapurna region. The tree rhododendron, which can grow many meters tall, dominates much of the section between Pitam Deurali and Low Camp. Its flowers range from deep red at lower altitudes to pink and white higher up.
The blooms usually peak in March and April, working their way uphill as spring advances, and in a good year the forest floor is carpeted with fallen petals. Even outside flowering season, the twisted, moss-covered trunks give the forest a fairy-tale feel. Above the treeline, smaller shrub rhododendrons cover the slopes around High Camp. Read about rhododendron season on Mardi Himal.
Oak, Bamboo and Moss Forests
Mixed with the rhododendrons are several species of oak, along with other broadleaf trees. In the damp, cloud-soaked middle section of the trek, trees are draped in thick moss, ferns and lichens, and epiphytes grow along the branches. Bamboo thickets appear in shaded, moist places. This cloud forest is one of the most atmospheric parts of the trail, especially when mist drifts through the trees. See oak, bamboo and moss forests of the trail.
Orchids and Wildflowers
Nepal is home to hundreds of orchid species, and several grow as epiphytes on trees along the lower and middle sections of the trail. Many flower during the monsoon and early autumn. On the open slopes above the treeline, alpine wildflowers such as primulas, gentians and edelweiss-like species appear in spring and summer, while autumn brings seed heads and golden grasses. Look carefully at the ground and the tree branches, as many of these plants are small and easy to miss. Read our guide to orchids and wildflowers on the trek.
Birds of the Mardi Himal Trek
The range of altitudes makes the trek rewarding for birdwatchers. Mornings are best, when birds are most active and the forest is quiet.
Himalayan Monal (Danphe)
The Himalayan monal, known locally as danphe, is Nepal's national bird. Males are dazzling, with iridescent green, purple, copper and blue plumage. They live in high forest and on open slopes near the treeline, and are sometimes seen around Badal Danda and High Camp, especially early in the morning. Read our guide to spotting the Himalayan monal.
Pheasants and Forest Birds
The kalij pheasant is commonly seen scratching in the forest undergrowth. Laughingthrushes, with their loud, chattering calls, move in noisy groups. Tits, warblers, sunbirds and minivets flit through the canopy, and in spring the forest is full of song.
Birds of Prey
On the open ridge, look up. Himalayan griffon vultures, one of the largest birds in the region, glide on thermals along the ridge and valleys. Bearded vultures, eagles and kestrels are also possible. Watching a griffon sail past at eye level from the ridge near High Camp is one of the trek's highlights. See vultures, eagles and birds of prey over Mardi Himal.
For more on identifying species and the best times to look, read our birdwatching guide.
Mammals
Langur Monkeys
Grey langurs, with their dark faces and long tails, are often seen in the forest, sometimes in large troops leaping between trees. They are generally shy but can be curious around lodges. Do not feed them. Read about langur monkeys in the Mardi Himal forests.
Himalayan Tahr
The Himalayan tahr is a sturdy wild goat with a thick, shaggy coat. Herds graze on steep grassy slopes and cliffs above the treeline, and are sometimes seen from the ridge between High Camp and Base Camp. Binoculars help. See Himalayan tahr on the Mardi Himal Trek.
Other Mammals
Barking deer can be heard and occasionally seen in the forest. Yellow-throated martens, pikas and various small rodents are possible. Leopards and Himalayan black bears live in the wider region but are secretive and very rarely encountered by trekkers. Evidence such as scratch marks or droppings is more likely than a sighting.
Insects, Reptiles and Leeches
In warmer months, butterflies are common in the lower sections, and the forest hums with insects. Reptiles are mostly small lizards basking on sunny rocks. During the monsoon, leeches are abundant in the damp forest below Low Camp. They are harmless but unpleasant. Tuck trousers into socks, use salt or repellent, and check your legs at rest stops. Read leeches on the Mardi Himal Trek.
A Walk Through the Zones, Day by Day
On the first morning, the drive from Pokhara passes rice paddies, banana plants and bamboo groves in the warm valley. From Kande, the trail climbs through terraces of millet, maize and mustard, depending on the season, with water buffalo and goats grazing around village houses. By Australian Camp, the air is cooler and the first oak and rhododendron trees appear along the ridge.
On the second day, above Pitam Deurali, you are fully inside the forest. The canopy closes overhead, the ground is soft with leaf litter, and the sound of birds replaces the sound of villages. Moss thickens on the trunks as you climb, and on misty days the forest becomes quiet and dripping. This is where you are most likely to hear laughingthrushes and see pheasants crossing the trail.
On the third day, somewhere between Low Camp and Badal Danda, the trees shrink and then disappear. Suddenly you are on open grassland with shrub rhododendron and juniper, and the sky feels enormous. Look up for vultures riding the wind and scan the slopes for tahr. Above High Camp, the vegetation becomes sparse, with tough grasses, cushion plants and bare rock, and in winter, snow.
How Local People Use the Forest
The forests along the trail have always supported the villages below. Traditionally, people collected fodder for livestock, leaf litter for animal bedding and compost, bamboo for weaving baskets and mats, and wood for cooking and heating. Today community forest user groups and the conservation area programmes help manage these resources, and many lodges use alternatives such as gas, solar power and improved stoves to reduce firewood use.
You may also see rhododendron flowers being dried or turned into a sweet, bright red juice, which is sold in some shops around Pokhara. Various plants are used in traditional remedies, and your guide may point some out. Collecting plants is not permitted for trekkers, so enjoy them where they grow.
Photographing Plants and Wildlife
Nature photography on Mardi Himal rewards patience. For flowers and moss, get low and use the soft light of cloudy days, which brings out colour and texture without harsh shadows. For birds and tahr, a telephoto lens or a camera with good zoom is essential, and early morning is best. Keep your camera ready rather than packed away, because a monal can appear on the trail and disappear within seconds. Our photography guide covers equipment and settings.
Best Seasons for Nature
- Spring (March–May): rhododendrons in bloom, active birdlife and nesting season. The best season for flora and birds.
- Monsoon (June–August): lush green forest, orchids and wildflowers, but rain, leeches and poor visibility.
- Autumn (September–November): clear skies, good visibility for spotting tahr and birds of prey, and golden grasslands.
- Winter (December–February): some animals descend to lower altitudes, making sightings more likely in the forest; snow tracks reveal wildlife activity.
How to See More Wildlife
- Walk quietly, especially in the forest in the early morning.
- Take breaks in open spots where you can scan slopes and sky.
- Carry binoculars; compact ones are light enough for any trekker.
- Ask your guide, who will know where animals are often seen.
- Listen for alarm calls from birds and monkeys, which often signal something moving.
- Be patient at viewpoints; birds of prey often appear once the air warms.
Watching Wildlife Responsibly
Never feed animals, including monkeys and birds, as it changes their behaviour and can make them aggressive. Keep your distance, especially from animals with young. Do not pick flowers, collect plants or disturb nests. Stay on the trail to avoid damaging fragile alpine vegetation. And avoid buying any products made from wildlife. Our guide to responsible wildlife watching explains these principles.
Useful Kit for Nature Lovers
A few light items make a big difference if you enjoy nature. Compact binoculars, around 8x25 or 8x32, weigh little and transform wildlife watching on the ridge. A small field guide to the birds of Nepal, or a bird identification app with offline content, helps you put names to what you see. A notebook lets you record sightings and flowering plants day by day. And a camera with a decent zoom, or a phone with a telephoto lens, lets you capture birds and tahr at a respectful distance. All of these fit easily into a daypack.
Nature and Climate Change
Like much of the Himalaya, the Mardi Himal region is feeling the effects of a changing climate, from shifting flowering times to changes in snowfall. Researchers are watching how plant and animal ranges move uphill as temperatures rise. Visiting responsibly and supporting conservation through your permit fees helps protect these ecosystems. Read climate change and the Mardi Himal region.
