In the Western Ghats, the spread of non-native plant species is rapidly replacing native vegetation, causing significant ecological imbalance. This invasion is leading to a food crisis as these plants disrupt the natural habitats of key prey species. As a result, wildlife is forced to enter human settlements in search of food, increasing conflicts between animals and communities.

Invasive species like Lantana, African Tulips, and Morning Glory are widespread, causing notable damage to our ecosystems. These aggressive plants are not native to India and are displacing traditional fruit-bearing trees such as mangoes, wild jack, wild berries, and other native plants in various forests. Their rapid growth makes them difficult to control, posing a threat to the health of our forests.

Tall Morning Glory

The Tall Morning Glory also known as Kaladana is a fast-growing vine that can reach 2-3 meters in length, with slender, hairy stems and heart-shaped leaves. Its vibrant blue, purple, or pink flowers are funnel-shaped, and it produces up to 25,000 seeds per plant, which can spread by wind, rain, or accidental human activity.

Kaladana grows by twining around other plants, creating a thick canopy that shades and competes with them for nutrients and water. This makes it a troublesome weed, as it can significantly reduce crop yields. It can also spread rapidly in both disturbed areas and forests, making it a challenge to manage.

Young seedlings can be easily pulled out by hand. For small patches, cutting the plant is an option, but make sure to dig out the roots to prevent it from growing back. In areas where the vine forms large patches, cutting followed by herbicide application is recommended to stop regrowth.

African Tulip

The African Tulip, also known as Pichkari and Rugtoora is a medium-to-large tree that can grow up to 35 metres tall, with a wide crown and smooth, greyish-brown bark. It has deep green, glossy leaves and produces striking orange-scarlet flowers, with its seeds dispersed by wind.

Pichkari trees invade open pastures, abandoned agricultural land, plantations, and disturbed forests. They grow rapidly, forming dense stands that suppress other vegetation. The flower nectar is toxic to insects, while mammals like Nilgiri langur and barking deer eat the flowers, and parakeets and squirrels consume the seeds.

To manage African tulip trees, young trees can be uprooted, though large trees may resprout from root fragments. Chemical control includes injecting herbicide into young tree trunks or applying it to stumps of cut trees. In some areas, biological control using pathogenic fungi has been effective for young trees.

Lantana

Lantana, or Raimuniya and Tantani, is a woody shrub that grows 2-5 metres tall. It thrives in both dry and wet environments, forming dense thickets or climbing trees. Found across India, including Goa, its leaves are rough, oval, and green with toothed edges. The small, colourful flowers attract butterflies, and its fruit turns from green to black, dispersed by birds and mammals.

Lantana's dense growth prevents native plants from growing and changes forest structure. It increases fire risks and is toxic to livestock, reducing available forage. Lantana also hosts diseases like sandal spike disease and suppresses important plants like amla, posing risks to forest communities.

The most effective removal method is cutting the plant below the root collar to prevent regrowth. Uprooting is less effective and labour-intensive. Consistent removal and establishing canopy cover can help control Lantana.

Conclusion:

There are many such invasive plant species altering habitats in our forests. Managing them in the forests of the Western Ghats is crucial for preserving biodiversity and ecological balance. Raising awareness about such species and promoting knowledge about native trees is essential for safeguarding our environment. 

This understanding is particularly valuable for individuals managing their gardens, such as in Goa, where knowing about trees in Goa is crucial for effective plant management. For further information on such species refer the book ‘Guests who never left’ and the article ‘No food in Forests’ for Invasive species in the Western Ghats.

Goa is a goldmine of biodiversity and trees are the crucial negotiators that tie these ecosystems together. As awareness increases about habitat loss and deforestation, people have taken the responsibility of hosting planting and re-wilding drives. The first step in this process is to identify and select plant species which are most effective and resource efficient for natural landscaping.

Here are popular, easy to source, and easy to plant species that are commonly found along Goa’s roads and within Goan homes.

AVENUE TREES

These trees are typically used for roadside planting owing to their large and extensive canopies that offer shade throughout the year. One often finds seasonal flowering trees chosen as avenue trees. However, fruiting varieties are typically avoided and are found mostly in private properties.

01 The Indian Laburnum

Cassia Fistula or The Indian Laburnum or Amaltas as it is locally called is a medium-sized deciduous tree. It is a sun loving tree that is known for its abundant and glorious yellow summer flowers. The tree is extensively found in Goa, especially along the roads of Panjim.

02 The Scholar’s Tree

The Scholar’s Tree or Satvin as it is locally called is a tall, evergreen tree with branches in whorls. The tree blooms in the winter with white, fragrant flowers that are found in clusters. The tree is found all over Goa and is also otherwise known as The Devil’s Tree.

HOME TREES

Goa’s incredible biodiversity is best experienced at home. Homeowners can choose to plant any native flowering or fruiting tree without worrying about extensive care or maintenance. Many of these trees are also found in Goa’s public gardens and are known to attract a wide variety of birds and butterflies. These trees also support a lot of insects and creepy crawlies. This post tells you how you can design to coexist with and celebrate Goa’s diverse flora and fauna.

03. The Frangipani Tree

Plumeria Rubra or Plumeria Obtusa or Frangipani or Champa as it is lovingly called is a tropical tree and is a residential favourite in Goa. The Champa shrub has a lovely sculptural form and requires little maintenance. The plant does not require too much water and can thrive in any well-drained soil. The flowers are fragrant, bloom throughout the year, and come in different colours.

04. The Traveller’s Palm

The Traveller’s Palm is a picturesque spreading tree that looks beautiful when used along compound walls and the site edges. The fan profile layers over and blurs the hard site edge while also creating privacy. The palm is water loving and retentive, making it a valuable landscape feature during Goa’s heavy monsoons.

Goa is a goldmine of biodiversity and native forests are the crucial negotiators that tie these ecosystems together. As awareness increases about habitat loss and deforestation, people have taken the responsibility of hosting planting and re-wilding drives. The first step in this process is to identify and select native plant species which are most effective and resource efficient for natural landscaping. Native trees offer huge short term and long term benefits:

• Native trees are well-adapted to the local climate, which means they will have the best chance at survival.

• Native trees prevent population decline of the local wildlife as the animals are not forced to shift into unfamiliar habitats.

• While non-native trees might not do well up against local pests, native trees often don’t have as many pest problems because they develop symbiotic relationships with other local species.

Here are 4 popular, easy to source, and easy to plant native species of Goa:

Terminalia Elliptica or The ‘Indian Laurel’ is the State tree of Goa. A few other names of this tree are Mati, Asna, Saj, or Crocodile Bark Tree.

Terminalia bellirica is a deciduous tree that grows upto 35 m in height. It is a sun loving tree that thrives in slightly moist soils. The fruit of the tree is often celebrated for its medicinal properties.

Pterocarpus marsupium, also known as Asann and Malabar kino is a deciduous tree that can grow up to 30 m (98 ft) tall. It is native to India, Nepal and Sri Lanka. The beautiful yellow flowered tree however is currently on the list of threatened species due to dwindling numbers and needs to be revived.

Holoptelea integrifolia, also called The Indian Elm is a deciduous tree that grows upto 25m in height. It is often sourced for timber which makes cheap furniture and also used as firewood in rural parts. Its flowers, leaves and bark have medicinal uses.

Apart from this Goa has several indigenous fruit trees including jack fruit, tamarind, guava, pineapple, and kokum. While these are not advisable for highways, they are wonderfully suited for smaller city avenues, parks, city campuses, and most importantly individual residential plots.
