Located in Alwar District, Rajasthan, Sariska Tiger Reserve used to be the hunting preserve of the Alwar estate. Spread over 880 square kilometres, this has always been an important connector of the Northern India tiger and leopard corridor. The reserve was declared a wildlife sanctuary in 1958 and a tiger reserve under the Indian government’s Project Tiger in 1979. Unfortunately, the robust population of around 28 tigers in Sariska was totally wiped out by 2003-04. Most were poached by the infamous Sansar Chand, who probably relied on the support of the local population and the still existing villages within the reserve. Whatever be the case, this unfortunate turn of events led to the vanishing of the apex level predator in the food chain in this area.

Everything is interrelated in the jungle. The demise of the tiger altered the topography of the park, resulting in a sharp increase in the population of antlers, the erstwhile favorite food of the tiger in the park. This spotted deer that I have photographed looks pretty, batting its ridiculously long lashes, but without the king of the jungle, rising deer populations decimated grasslands and shrubs. The resultant forest degradation made the habitat even more difficult for wildlife to survive and thrive.

In 2009, Sariska became the first reserve in the world where tigers were successfully relocated. These were the first tigers this thorny, arid scrub forest had seen in years. The joy was, however, short-lived. The first reintroduced male tiger died after feeding on a poisoned cattle carcass and relocated tigresses did not breed as expected. Was the forest too stressed because of human activity for it to regenerate and tigers to flourish once more?

Things started looking up by 2012, when a female tigress named ST-2 was sighted with cubs. Sansar Chand died in 2014 and poaching activities slowed down. Better forest management techniques were subsequently enforced and big cats started making a slow comeback. Relocation of six villages from the core areas reduced human activity inside the jungle. This improved the habitat and gave tigers much needed space to move about freely. 

Sariska has become a success story with the tiger population going up steadily. 23 tigers live here now, including three cubs. The enforced lockdown has given an unexpected and happy boost to the conservation efforts at the Park. This year, I have seen several individuals, including ST9, ST3 and ST6. Since September 2021, ST21 and ST9 have been courting. Hopefully their courtship will herald some good news for conservationists here!

In architecture, the keystone at the top of an arch holds the arch together. Without the keystone, the whole arch and building surrounding collapses! Tigers are regarded as keystone species in their habitat. The return of tigers to Sariska has had an immeasurable impact on its biodiversity and ecological health. 

Today, the slow but steady repopulation of tigers in Sariska holds important lessons in the viability of such rewilding programs. Do radio collars around the neck hinder breeding success? Can rewilding be successful in forests with a lot of human activity? Are some tigers more efficient breeders than others? And what can be done to improve the survival rate of tiger cubs? Perhaps the answers to such questions will bring greater focus and success to species reintroduction programs across the world. 

In the meantime, Sariska has become my favourite weekend destination from Delhi to get a quick and wholesome experience of these majestic creatures in the wild!

We think of Delhi as a concrete jungle, which, indubitably, it is. However, the city is on the tail end of the Aravallis and their forests, many of which are, happily, in different stages of rewilding. Recent surveys of these forests show that they harbour an astonishingly rich diversity of wildlife with relatively high densities of mammals in non-protected areas. As someone who has been documenting life in these forests over the last few decades, I have, in recent times, chronicled many species that used to be rare to find and can now be spotted.

The growing awareness about the conservation and protection of Delhi’s urban forests is a welcome breath of fresh air for conservationists and wildlife lovers like me. Much more needs to be done but I am happy that in my years as a chronicler of the city’s animals, I have got to see some of these amazing species return to their lost habitats.

One of Australia’s great forests once grew hidden from sight off the east coast of Tasmania. Swathes of giant kelp, known as kelp forests, grew from the ocean floor, towering 30 to 40 metres into massive floating canopies across the surface of the sea. “They were charismatic, six to seven storey tall underwater jungles, basically,” says Cayne Layton, postdoctoral research fellow at Tasmania’s Institute for Marine and Antarctic Studies. “It is said that some floating canopies were so thick that they were on navigation charts as a navigational hazard.”

Today, 95 percent of this globally significant forest of the world’s fastest-growing plant – giant kelp can grow up to 50 centimetres a day – has been wiped out by the inexorable shift of the warm East Australian Current – the ocean current made famous in the movie Finding Nemo – displacing the cold, nutrient-rich Southern Ocean waters. The remaining five percent now grow only in scattered patches. The decline of these forests, listed as Australia’s first endangered marine community, has been relentless since the 1940s, largely unnoticed and unremarked by the local community. But the fightback has begun, and the early results are promising.

In the spring of 2020, Layton and a team of scientists planted three restoration plots of kelp on rocky reefs along Tasmania’s east coast, having collected spores from surviving giant kelp plants identified as tolerant to the warmer seas.

The scientists planted tens of thousands of millimetre long juvenile kelp on the reefs. When they returned months later, at the end of summer, they were greeted by a beautiful sight.

“One of the sites had no survivors, but at the two other sites we had really good success,” Layton says. “At those two now, we have over 200 surviving giant kelp. The average size is about a metre, and the largest is over four metres tall, so they’re kind of like stringy teenagers at the moment.

“The really exciting thing for us is that in those first assessments after summer, the kelp looked really healthy. That was encouraging – that the increased thermal tolerance we found in the lab was translated to the field.”

The team will again plant giant kelp this winter, and hope to do so each year into the future.

The rehabilitation of these underwater forests has been touted as a tool in the quest to mitigate climate change – great forests that absorb great quantities of carbon – though Layton cautions that the science is still young when it comes to giant kelp’s carbon sequestration ability. Such efforts, along with regrowing seagrasses, are central to marine protection as the climate warms.

Their value to the planet and marine communities, however, is unquestionable. And moment by moment, these fast-growing marine marvels are now straining once more towards the sun and perhaps even a return one day to navigation charts.

“We’re very happy (with the planting), but it’s still early days,” Layton says. “We want these individuals to grow up and become mature and start producing their own babies. Restoration is never going to work if it’s reliant on me and my colleagues planting these kelp. We’ve got to kickstart the natural cycle, so those individuals that we plant start producing their own juveniles.

“They can reach reproductive age within a year, so we’re hoping that towards the end of this year the largest ones will start to become reproductive. That’ll be the next big exciting step for us.”
