Recent scientific studies on Deodar trees in the Sangla Valley of Himachal Pradesh have revealed valuable evidence of long-term climatic shifts. Tree-ring data indicate a transition from wetter spring conditions during pre-historic times to drier climatic conditions from around the year 1757 onwards, highlighting the role of Deodar trees in climate reconstruction.

About the Deodar Tree

The Deodar tree, also known as the Himalayan Cedar, is one of the most revered and iconic tree species of the Western Himalayas. The name Deodar is derived from the Sanskrit word “Devad?ru”, meaning “wood of the gods”, reflecting its deep cultural and spiritual significance in Indian traditions.

Geographical Distribution

Deodar trees are mainly found in the western Himalayan region, forming an important component of temperate forest ecosystems.

Ecological and Cultural Importance

The Deodar tree plays a critical ecological role in high-altitude forest systems and also holds immense cultural value. Traditionally, its durable wood has been used in temple construction, religious rituals, and Ayurvedic medicine.

Habitat and Climatic Requirements

Deodar trees thrive in well-drained soils and moist temperate climatic conditions. They are commonly found at altitudes ranging between 1,800 and 3,000 metres, particularly in alpine and subalpine forest zones.

Physical Characteristics

Deodar is a large evergreen conifer that can grow up to 50 metres in height. It has a tall pyramidal shape, with drooping branches and needle-like bluish-green leaves.
The bark is dark grey, becoming deeply fissured as the tree ages. The tree bears solitary, erect, ovoid cones, which are dark brown in colour. Both male and female cones occur on the same tree.

Threats to the Deodar Tree

Despite its importance, the Deodar tree faces several threats, including excessive logging, habitat loss, and the impacts of climate change, which have affected its natural distribution and regeneration.

Scientists have recently reported that a combination of extreme heat stress and a rare outbreak of Black Band Disease has destroyed nearly 75 per cent of Goniopora coral colonies at a site on the Great Barrier Reef.

About Goniopora Coral

Goniopora, commonly known as flowerpot coral or daisy coral, is a type of hard coral belonging to the Poritidae family. It is known for its striking appearance, as its polyps resemble the petals of a flower.

Physical Characteristics

Goniopora coral colonies consist of small branching columns, which are generally oval in transverse section.
The polyps can range from a few centimetres to several centimetres in diameter, giving the coral its distinctive floral appearance.

Habitat and Distribution

Goniopora typically inhabits lagoons and turbid reef environments.
It is considered relatively thermally tolerant, allowing it to survive across a range of temperature conditions compared to many other coral species.

Nutrition and Symbiosis

Goniopora is a photosynthetic coral and derives part of its nutrition from sunlight.
It maintains a symbiotic relationship with dinoflagellates known as zooxanthellae, which live within the coral’s tissues and supply energy through photosynthesis.

The coral can thrive under a wide range of lighting conditions.

Feeding Behaviour

In addition to photosynthesis, Goniopora is predatory in nature.
It captures small organisms from the surrounding water to supplement its nutritional needs.

Black Band Disease

Black Band Disease is a bacterial necrotic infection that attacks living coral tissue.
The disease forms a distinct black band that moves across the coral surface, usually resulting in the death of the colony.

Distribution and Causes

The disease is commonly observed in Caribbean reefs but is rare in Australian waters.
It is often associated with pollution, nutrient runoff, and degraded water quality, which create favourable conditions for the disease-causing bacteria.

Significance

The large-scale loss of Goniopora corals due to combined climate stress and disease highlights the increasing vulnerability of coral reef ecosystems under global warming and environmental pollution.

The rare migratory Pallas’s Gull was recently sighted at Udhwa Lake Bird Sanctuary in Jharkhand, marking its return after nearly a decade. This sighting highlights the ecological importance of the sanctuary along major migratory routes.

About Pallas’s Gull

Pallas’s Gull, also known as the Great Black-headed Gull, is a large gull species belonging to the Laridae family.
Its scientific name is Ichthyaetus ichthyaetus.

It is the world’s largest black-headed gull and the third-largest gull species globally.

Distribution and Migration

Pallas’s Gull breeds in colonies on marshes and islands across southern Russia to Mongolia.
It is a migratory bird, spending winters in the Mediterranean region, the Arabian Peninsula, and the Indian subcontinent.

Habitat

The species prefers wetland ecosystems, including salt lakes, lagoons, marshes, and slow-flowing rivers.

Physical Features

Pallas’s Gull measures 55–72 cm in length with a wingspan of 142–170 cm.
During the summer breeding season, adults are easily identifiable due to their distinct black hood, a feature unique among gulls of similar size.

The adults have grey wings and back, with prominent white “mirrors” at the wing tips.
Their legs are yellow, and the bill is orangey-yellow with a red tip.
In non-breeding plumage, the black hood fades, leaving a dark mask across the eye.

Diet

Pallas’s Gulls are omnivorous and predatory.
They primarily feed on fish, including dead fish, but also consume insects, crustaceans, reptiles, other birds, and small mammals.

Conservation Status

The species is classified as Least Concern under the IUCN Red List, although habitat loss and wetland degradation remain long-term concerns.

Udhwa Lake Bird Sanctuary

Location and Status

Udhwa Lake Bird Sanctuary is located in the Sahebganj district of Jharkhand.
It is the only bird sanctuary in the state and was designated a Ramsar Site in 2025.

Geographical Features

The sanctuary comprises two interconnected wetlands—Pataura Lake and Berhale Lake.
These lakes are part of the Ganga River floodplain and are surrounded by the Rajmahal Hills.

Biodiversity Significance

The sanctuary supports a rich ecosystem with over 146 bird species, including endangered birds such as the band-tailed fish eagle, lesser adjutant stork, and common pochard.

It also harbours diverse aquatic plants, fish, reptiles, and mammals, including fishing cats and otters.

Migratory Importance

Udhwa Lake Bird Sanctuary lies along the Central Asian Flyway, making it an important wintering and stopover site for migratory birds, including rare species like the Pallas’s Gull.

A recent Nature Sustainability study has highlighted that invasive alien plants are spreading across nearly 15,500 square kilometres of India’s natural areas every year. Over the last 60 years, these invasions have caused economic losses estimated at ?8.3 lakh crore and pose serious threats to ecosystems, wildlife, agriculture, and rural livelihoods.

What are Invasive Alien Plant Species?

Invasive alien plant species are non-native plants that are introduced either intentionally or unintentionally into ecosystems outside their natural range. Once established, they outcompete native species, disrupt ecological balance, and cause economic, environmental, and human health impacts.

The spread of invasive plants is being accelerated by climate change, land-use changes, altered fire regimes, soil moisture variations, livestock grazing patterns, and widespread biodiversity loss.

Major Invasive Plant Species in India

Some of the most aggressive invasive plant species in India include:

• Lantana camara

• Chromolaena odorata

• Prosopis juliflora

Together, invasive plant species have already spread across 266,954 square kilometres of India’s natural habitats.

High-Risk Regions and Vulnerable Ecosystems

Regions facing particularly high invasion risks include:

• The Shivalik–Terai belt

• The Duar region of Northeast India

• The Aravalli range

• Dandakaranya forests

• The Nilgiris in the Western Ghats

Open ecosystems such as dry grasslands, savannas, shola grasslands, and the wet plains of the Ganga–Brahmaputra basin are especially vulnerable due to their ecological openness and frequent human use.

Impacts of Invasive Alien Plant Species

Biodiversity and Ecosystems

Invasive plants aggressively replace native vegetation, leading to ecosystem homogenisation, soil degradation, and large-scale ecological disruption. As native plants decline, herbivores lose their natural food sources, which in turn reduces prey availability for predators, destabilising entire food webs.

Livestock and Agriculture

The spread of invasive species reduces the availability of fodder and grazing lands, directly affecting livestock health and productivity. By 2022, about 2.79 million livestock and nearly 2 lakh square kilometres of smallholder farmland were exposed to invasive species impacts.

Human Livelihoods and Health

Invasive plants reduce access to fodder, fuelwood, and fertile land, undermining rural livelihoods. They also contribute to health problems such as respiratory ailments and deepen poverty by weakening income security. Around 144 million people have been exposed to risks associated with invasive plant spread.

Challenges in Managing Invasive Plant Species in India

1. Institutional Gaps
   India lacks a dedicated national mission or central authority to coordinate invasive species management.

2. Data and Monitoring Deficit
   There is no unified national database or long-term monitoring system for invasive plants.

3. Weak Biosecurity Measures
   Ineffective quarantine and border controls allow new invasive species to enter the country.

4. Limited Scientific Research
   There is insufficient research on species-specific control methods and long-term ecosystem recovery.

5. High Cost of Manual Removal
   Manual removal is labour-intensive, costly, and often ineffective without sustained follow-up.

6. Poor Post-removal Restoration
   Many cleared areas are not restored, enabling rapid reinvasion by invasive species.

Measures Required for Effective Management

• Establish a National Invasive Species Mission with clear leadership and mandates, and integrate invasive control into climate adaptation, watershed management, and ecosystem restoration programmes.

• Develop a centralised GIS-based database, early-warning systems, and a nationwide monitoring network.

• Strengthen quarantine screening, border biosecurity, and import regulations for plants, seeds, and soil.

• Increase research funding for ecological modelling, biological control, and restoration science.

• Promote community-led removal efforts, supported by mechanical tools and sustainable utilisation options such as biofuel production.

• Ensure active ecological restoration using native grasses and shrubs after removal to prevent reinvasion.

Conclusion

The rapid expansion of invasive alien plant species in India poses a serious threat to biodiversity, ecosystems, and rural livelihoods. Addressing this challenge requires urgent, coordinated national action, strong institutions, scientific research, and community participation. A comprehensive national mission is essential to build long-term ecological resilience and safeguard India’s natural heritage.
