On a map, Kaziranga National Park has a boundary. A rhino does not.

When the Brahmaputra rises, and the grasslands begin to disappear under floodwater, a rhino may move towards higher ground. An elephant may follow an old route into the Karbi Anglong hills. The animal does not stop because a line on a map says the protected area has ended.

Hold on to that image, because it is the whole story. Everything now being argued over — the viral posts, the court orders, the trucks in the riverbeds — comes down to a single stubborn fact: the creatures Kaziranga exists to protect have never agreed to stay inside it.

The argument itself began on 8 August, when the Assam government announced that the state would seek to have the Eco-Sensitive Zone (ESZ) around Kaziranga National Park and Tiger Reserve formally notified at one kilometre instead of the 10-km default provision.

Within hours it was everywhere: a protective buffer, people said, was being shrunk by ninety per cent.

It is a clean, alarming story. It is also not quite the story.

Because it raises a sharper question than the one trending online: who protects the land beyond Kaziranga's boundary, when the animals don't recognise it in the first place?

The Better India looked at court orders, government records, complaints, reports, and recent developments around Kaziranga. Mining, construction, roads, rivers, flood refuges, and wildlife corridors all intersect here, and much of it is unfolding right now, while the timeline fills with arguments about a single number. After speaking to conservationists and examining those concerns, the real question turns out to be this: can the larger landscape that sustains Kaziranga stay connected at all?

First — what is the 10-km rule, really?

An Eco-Sensitive Zone is meant to create a regulated area around protected forests, national parks and wildlife sanctuaries, so that activities capable of placing pressure on these ecosystems can be controlled.

It does not mean every human activity inside an ESZ is banned. Different activities can be prohibited, regulated, or permitted depending on the applicable rules and notification. Mining and highly polluting activities face the most stringent restrictions.

So Assam is cutting a firm 10-km shield down to one — that's the outrage, and that's the story. Except here is the detail almost no one arguing about it has mentioned:

There is no final, formally notified 10-km Kaziranga ESZ. There never has been.

In its 3 June 2022 judgment, the Supreme Court directed that every national park and wildlife sanctuary should have an ESZ of at least one kilometre from its demarcated boundary. It also said that where a wider ESZ already existed, or where a wider buffer had been proposed and was awaiting a final decision, that wider area would continue to prevail.

A subsequent legal proceeding in 2026 recorded the position even more clearly. The Gauhati High Court noted that where a protected area's ESZ has not been finally notified, the 10-km buffer continues to operate as the default, with ESZ restrictions applying within it.

The court also recorded that, at that time, no final Kaziranga ESZ notification had been submitted by the state to the Centre.

Which means the viral........
