How border wall affect wildlife?

Barriers of any kind affect movement and migration of animals. For instance, the wall could come in the way of an animal’s search for water and food nearby. It could also stop animals on their long-distance migratory paths.

When he was the U.S. President, Donald Trump set off the expansion of the border wall between the U.S. and its neighbouring country Mexico. While he’s not the country’s President any longer, the incomplete construction stretching miles on end stands today, silently bearing testimony to human prejudice. It divided people on both sides physically and emotionally. But it appears to have affected more than just humans as with barriers anywhere globally, it has affected wildlife too.

Wildlife has no concrete borders, created singularly by and for humans. When humans introduce these barriers, wildlife struggle, to put it mildly. It has come to light that the case is no different with the U.S.-Mexico barrier. According to Cuenca Los Ojos (CLO), a transfrontier wildlife organisation, “camera trap photos and the conservationists own observations have revealed deer, mountain lions and black bears pacing along the border wall, confused and unable to access their former ranges”. “One family of boars spent five hours trying to get past the wall in search of water, according to CLO. Barriers of any kind affect movement and migration of animals. For instance, the wall could come in the way of an animal’s search for water and food nearby. It could also stop animals on their long-distance migratory paths.

Apart from animals, such walls can harm birds too. When these barriers are lit up at night, it can disorient both nocturnal birds and those on their long migratory journeys. While it is easy to presume that birds can effortlessly cross such barriers in daylight, the reality is different. A few birds are low-fliers, and different types of interferences in a natural landscape can leave them trapped in one place due to their inability to fly from it. According to research conducted a few years ago on the U.S.-Mexico border, “not only large roadways but also big agricultural fields and other types of landscape disturbance and segregation” affected the movement of ferruginous pygmy owl, a low-flying bird.

Erecting walls or barriers is not new. However, with the natural world already under threat from climate change, these human structures, especially in places rich in biodiversity, are likely to put further pressure on wildlife.

WHAT ARE THE CAREER OPTIONS FOR WILDLIFE LOVER?

Love the thrill of watching a butterfly flutter by? The excitement of discovering the name of a tree species? Understanding how living beings evolve? If you’re a wildlife lover, here are four career options you can explore.

Marine biologist

What to study: BSc in marine biology or a related field such as oceanography, marine science, or earth science, followed by a Masters.

What the job entails: Marine biologists study animal, plant, and microscopic life in oceans. But this does not mean they’re always into deep-sea diving! They work with samples in research laboratories for any discoveries, and also prepare reports worthy of publication.

Benefits: In addition to closely observing all kinds of marine creatures, they could be a changemaker. Apparently, a little more than three-fourth of all life on our planet is found under the ocean surface. And since they are also indicators of the changes around us – such as pollution and climate change – marine biologists could be the one to announce this to the world, nudging citizens to be responsible and protect our world.

Challenges: While not always, field work – in oceans – can be physically demanding, due to being in water for a long while, lugging heavy equipment, etc. The location could be remote, affecting one’s social life for long periods of time.

Wildlife photographer/ filmmaker

What to study: For both photography and filmmaking, there are degree and short-term courses offered both in India and abroad.

What the job entails: As is evident from the job title, one photographs or shoots films about wildlife. It also involves team work, constant learning, being aware, fit, resilient, quick to adapt, among others.

Benefits: Watching wildlife, learning about them, and enlightening the layperson. Though it is not a 9-to-5 job, it has the potential to be lucrative. Professionals can even be part of wildlife magazines or television channels. And, there is recognition. going by the growing number of awards presented to wildlife photographers and filmmakers globally. But, do they match the reward of watching Nature up-close?

Challenges: While the technicalities of shooting a picture or film/ documentary can be learnt through professional courses offered across the globe, certain aspects are learnt on the job. For instance, patience and acceptance. Nature is what it is one has no control over timing the blooming of a flower or a tiger snagging its prey. Sometimes no matter how much one is prepared, the result may not be what one wants.

Wildlife rehabilitator

What to study: While a degree in biology or ecology is seen as necessary, the subjects covered could include ornithology, mammalogy, animal behaviour, etc.

What the job entails: Wildlife rehabilitators care for and treat injured, orphaned, or displaced wildlife. Their aim is to ensure that the animals are healthy and prepared appropriately to finally return to the wild.

Benefits: In addition to saving and protecting wildlife, they play a huge role in rescuing animals during natural disasters and also educating people about wildlife. Their role helps reduce human-wildlife conflicts, and create a sense of responsibility among people towards wildlife.

Challenges: In this line of work, it is not possible to save every animal one rescues. It is important to understand that sometimes, an animal’s life is beyond one’s control.

(Natural History) Museum curator

What to study: Masters in biology, ecology, museum studies, etc. Some museums may require doctoral studies in related fields, in addition to work experience.

What the job entails: As with most other jobs, this one too spans a wide range of responsibilities. However, what is particularly vital is that the curator possesses the wisdom and necessary skills to gather, understand, and put together a dynamic collection of relevant specimens that can be viewed on a regular basis or specifically presented in highly stimulating and themed exhibitions.

Benefits: The greatest take away from the job could be the pleasure of learning. and working with a rare and an incredible variety of specimens, some of which could go back even centuries. And, of course, the opportunities to interact with curious visitors who may share the curators joy in natural history.

Challenges: If the museums are small, one is likely to take on several responsibilities, as mentioned earlier. This, of course may mean longer working hours but a richer learning experience too. Since many of the specimens will be very old and fragile, extra care is required in handling them.

WHAT IS SO SPECIAL ABOUT SOCOTRA ISLAND?

Hosting hundreds of plant and animals species that are found nowhere in the world, it’s small wonder that Yemen’s Socotra archipelago has been called the Galapagos of the Indian Ocean.

Full of life!

Located more than 300 km from its parent country Yemen, the Socotra archipelago comprises four islands in the Indian Ocean between Somalia and Yemen. Covering a total area of nearly 4,000 sq.km., the islands are known for their rich biodiversity and unique flora and fauna. For instance, among the 825 plant species found in the region now, as many as 307 cannot be seen anywhere else in the world. Birds such as the Socotra starling, Socotra sunbird, and Socotra warbler are said to be found only here. A staggering 90% of reptile species and 95% of land snails too are said to be endemic (found nowhere else). Because of this, the place is often referred to as the “Galapagos of the Indian Ocean”.

Lying close as it does to the African continent, the archipelago appears to be the extension of the Horn of Africa. About 20 million years ago, these islands were believed to have broken off the Gondwana supercontinent. The archipelago was declared a UNESCO World Heritage Site with “Outstanding Universal Value” in 2008. Though the habitats within the region appear to be healthy and safe, they are not without threat. These include tourism, invasive species, overusing of natural resources and natural disasters. In fact, the conservation outlook for this site has been assessed as “significant concern” in the latest assessment cycle 2020.

Wildlife

Nearly 200 species of birds, including land and sea, are said to be seen in the archipelago. Among them are garganeys, shovelers, pintails, teals, ducks, guinea fowls, quails, flamingoes, grebes, pigeons, doves, sandgrouses, coucals, nightjars, swifts, moorhens, stilts, plovers, stints, snipes, sandpipers, coursers, gulls, terns, tropicbirds, petrels, shearwaters, boobies, egrets, herons, ibises, ospreys, buzzards, owls, hoopoes, bee-eaters, falcons, shrikes, ravens, larks, martins, swallows, warblers, whitethroats, thrushes, wheatears, starlings, sunbirds, pipits, wagtails, buntings, and sparrows. As an archipelago, the region has a startling variety of corals, fishes, crabs, lobsters, and shrimps too, together adding up to more than 1,000 species!

Dragon’s blood tree

Synonymous with the identity of Socotra, the dragon’s blood tree is found nowhere else in the world. It “lives within remnants of prehistoric ‘Dragonsblood forest on granite mountains and limestone plateaus” within Socotra.

Marked by a unique umbrella-shaped canopy, the tree is said to capture the moisture in the air through its leaves and take it to the roots. Having held an economically significant role for centuries, the tree has varied uses. When fed to cattle in very small quantities, the tree’s berries are said to improve the animals’ health.

The tree gets its name from the red-coloured resin it produces, and this resin is believed to have several medicinal uses. The International Union for Conservation of Nature’s conservation status for the tree is “vulnerable”.. Shockingly, it has been discovered that hardly any “populations are regenerating naturally”. In addition, it has been noticed that “in some areas young trees lack the species’ characteristic umbrella shape”.

As climate change intensifies, “Socotra is drying out, with once reliable monsoon weather becoming patchy and irregular. And this could spell irreversible change to the archipelago and its unique inhabitants.

HOW IS WILDLIFE AFFECTED BY WAR?

History is full of evidence pointing to the futility of war. And still, humans continue to fight with each other often for reasons best left unsaid. While global conversations focus largely on the unimaginable impact of war on innocent humans, the less-spoken aspects such as its lasting impact on wildlife and their habitats are gaining traction, especially in the wake of Russia’s ongoing war on Ukraine. In yet another indication of humans wrecking the natural world and their inhabitants, scientists suggest that the ongoing war could have cost dolphin lives.

Since the war began a few months ago, the number of common dolphin deaths in the Black Sea has spiked. Researchers feel that war-related activities – such as the movement of Russia’s navy vesssels and military actions in the northern part of the Black Sea (spanning Ukraine) have increased noise pollution. And, this is perhaps pushing these marine creatures down south to the shores of Turkey and Bulgaria, “where they are being stranded or caught in fishing nets in unusually high numbers”. So far, at least 80 of these cetaceans have been found dead on Turkey’s Black Sea coast, and this has been termed “an extraordinary increase”. While about half this number points to entanglement in fishing nets, the reason for the rest is not dear since the dead dolphins show no visible injuries. This has set scientists thinking.

They wonder if the deaths could be the result of “acoustic trauma” (damage caused by noise). Marine creatures are dependent on sound for several reasons such as communication, and when there’s underwater noise- such as navy vessel movement-it can lead to dolphin deaths. The noise may not kill them directly or always. When the noise levels increase, marine creatures such as dolphins are likely to head towards areas they are not familiar with which could lead to stranding. While more concrete research is required for scientific reasoning. it is perhaps undeniable that human conflict is costing animal lives. Yet again.

Where can you find the gorilla?

The gorilla lives in the dense forests of equatorial Africa. It is the largest and most powerful of the ape family. The gorilla is extremely strong but it is a unduly disturbed. But other animals are very much afraid of it: few of them will dare to attack a gorilla because they know they would have the worse of the encounter.

A full-grown gorilla stands nearly 2 metres tall, with a massive body and very muscular arms and legs, and can weigh over 200 kilograms. Its jaws jut out and it has a broad, flattened nose and huge beetling eyebrows.

There are two main kinds of gorilla: the lowland gorilla that lives in the rain forests of western Africa, has a dark grey coat; the mountain gorilla which lives in the eastern regions of Zaire-Uganda borderland at altitudes of more than 3,000 metres, has black fur, Little is known about the ways of these big apes. This is because gorillas are very shy animals and also because they were first found only during the last century.

Gorillas usually live in groups which include both young and old. They build rough dwellings in trees a few metres above the ground. These dwellings look like platforms made of branches and twigs.

Gorillas do not spend all their lives in the trees. During the day they wander about on the ground looking for food. They feed on leaves, roots and fruit which the forest has in plenty. Gorillas walk in a crouching position, but every so often they stand up straight on their long hind legs.

Why reindeer migrate?

In spring the Lapps leave behind the woodlands of the south where they spend the winter and set out for the pastures in the northern mountains. The Lapps move in small family groups, leading their herd of reindeer along established tracks which usually follow the courses of river. The rivers are still frozen and the Lapps us them as safe roads for their sledges, laden with provisions. The reindeer are used to following the same route and move along slowly, feeding as they travel.

Half-way through the journey, when spring breaks, the Lapps pitch their tents for a period lasting several weeks. It is at this time that the baby reindeer are born and the tribe has to wait until they are able to walk by themselves. The young reindeer do not take long to learn how to trot about and the herd moves on once more. The destination is the far north where the tundra, the ‘cold desert’ of northern Norway, Sweden, Finland and Iceland, ends and the Arctic Ocean begins. The reindeer herd spends the short summer on the grassy shores and on the islets along the coast before travelling south once more.

Lapps consume large quantities of reindeer milk and use it to make delicious cheese. When the icy north wind blows and the family is gathered together in the tent the mother prepares a hot drink by dissolving chunks of reindeer cheese in hot water. This drink provides a great deal of energy and warmth.

Lapps have hunted reindeer since the earliest times and have kept small numbers, but breeding them in large herds is comparatively recent.
