Why Kashmir’s Chinar Trees Turn Fiery Red Every Autumn While Many Indian Trees Stay Green

A chinar is a deciduous tree known locally as boen or buen and scientifically as Platanus orientalis. It is Jammu and Kashmir’s state tree. Its enormous canopy provides welcome shade during summer. In autumn, its leaves turn yellow, orange and red, creating one of the Valley’s most recognisable sights. This seasonal display signals that winter is approaching.

The chinar also carries deep cultural meaning. Mughal rulers planted chinars across the Valley, including at Srinagar’s Naseem Bagh near Dal Lake. Its distinctive leaves appear in Kashmiri embroidery, carpets and papier-mâché. The tree therefore connects Kashmir’s natural scenery with its history and artistic traditions.

Chinars have faced damage, neglect and unauthorised cutting. In January 2025, the Tree Aadhaar initiative had geo-tagged 28,560 individual trees. Their records include location, age, size, health and possible threats. Protecting these trees could help future generations enjoy their summer shade and autumn colours.

From October, chinar leaves begin losing their broad green colour. Yellow appears first, followed by orange and red shades. By November, whole trees may seem to glow in the autumn sunlight, with leaves ranging from golden yellow to deep crimson. For Kashmiris, this transformation is a familiar sign that winter is near.

The key mechanism begins inside each leaf. Shorter days and falling temperatures tell the tree that colder weather is approaching. Before shedding its leaves, the tree withdraws useful nutrients for storage. As chlorophyll breaks down, carotenes and xanthophylls become visible. These pigments produce yellow and orange shades that were already present but hidden by green.

Red has a different pathway. Anthocyanins can form as autumn progresses, influenced by sunlight, temperature and sugar levels in the leaf. Scientists have not established which pigments create every crimson shade in Kashmir’s chinars. The 2011 article specifically explains yellow and orange pigments.

By January 2025, Kashmir’s Tree Aadhaar initiative had geo-tagged 28,560 individual chinar trees. Geo-tagging gives each tree a unique identity, allowing authorities to track it rather than treating every chinar as part of an uncounted group. This creates a clearer picture of the trees that remain across the region.

The records contain practical details about each tree. They include its location, age, size and health. They also record possible threats. This information can help identify trees needing attention and support efforts to respond to damage, neglect or unauthorised cutting. Project coordinator Dr Syed Tariq reported the figure to The Indian Express.

The initiative reflects the chinar’s importance beyond its autumn beauty. Chinars provide summer shade and carry historical and cultural value. Keeping individual records offers a way to monitor them over time. The stated hope is that future generations will still see golden and crimson leaves each autumn.

The chinar became part of Kashmir’s identity through both landscape and culture. Mughal rulers planted these trees widely across the Valley. Their planting helped make chinars a familiar feature of Kashmir’s gardens and public spaces. Naseem Bagh near Dal Lake in Srinagar is one named example.

The tree’s influence also appears in Kashmiri crafts. Its distinctive leaves continue to appear in embroidery, carpets and papier-mâché. These designs bring a recognisable natural form into handmade objects. The chinar is therefore more than a seasonal tree. Its image links Kashmir’s environment with its artistic traditions and historical past.

That identity also explains why protecting chinars matters. The trees have faced damage, neglect and unauthorised cutting. Tree Aadhaar is helping authorities track individual trees, including their locations, ages, sizes, health and possible threats. Preserving chinars protects both a living part of Kashmir’s landscape and a symbol represented in local crafts.

Chinars respond to Kashmir’s autumn conditions because they are deciduous trees. As autumn brings shorter days and falling temperatures, the tree senses that winter is approaching. It begins preparing for colder months and eventually sheds its leaves. This seasonal timing helps the tree conserve resources before the next growing season.

The colour change starts when chlorophyll, the substance that makes leaves green, gradually breaks down. The tree first draws back useful nutrients and stores them for later use. With less green chlorophyll masking the leaf, carotenes and xanthophylls appear yellow and orange. Anthocyanins may produce red or purple shades as autumn continues, influenced by sunlight, temperature and sugar.

Many trees in warmer parts of India follow different seasonal patterns. Some stay green throughout the year, while others shed leaves during the dry season. Their surroundings do not trigger the same autumn sequence as Kashmir’s chinars. Thus, climate helps explain why chinars display vivid autumn colours while many warmer-region trees remain green.

When chlorophyll breaks down, the leaf loses its green colour and hidden pigments become visible. Before the leaf falls, the chinar withdraws useful nutrients from it. These nutrients are stored so the tree can use them again when spring arrives. Leaf colour is therefore part of preparation, not merely a beautiful display.

The process follows autumn’s shorter days and cooler temperatures. Carotenes and xanthophylls show yellow and orange shades after chlorophyll declines. Red pigments called anthocyanins can be produced as autumn progresses. Their formation is influenced by sunlight, temperature and the amount of sugar in the leaf. The exact pigments behind every crimson shade remain uncertain.

After nutrients have been recovered, the chinar sheds its leaves before winter because it is deciduous. This helps the tree conserve resources through the colder months. The cycle continues into the next growing season, when stored materials can support new growth. Kashmir’s autumn colours therefore mark a practical survival process.

Chlorophyll is the green substance that helps leaves absorb sunlight. The leaf uses this energy to turn water and carbon dioxide into sugars that help the tree grow. During autumn, chlorophyll gradually breaks down. Once its strong green colour fades, other pigments that were already in the leaf become easier to see.

Carotenes and xanthophylls are the pigments responsible for yellow and orange shades. They are revealed as chlorophyll declines. Red and purple shades often come from anthocyanins. Unlike the yellow and orange pigments, anthocyanins can be produced as autumn progresses. Their formation is influenced by sunlight, temperature and the amount of sugar in the leaf.

These pigments explain much of the chinar’s autumn display, but not every detail is settled. The 2011 Science Reporter article specifically explains yellow and orange pigments. Scientists have not established exactly which pigments produce every crimson shade seen in Kashmir’s chinars. The colours combine biology with Kashmir’s seasonal conditions.
