Millions of people know the Maasai Mara without ever having been. They know it through a marsh, a pride of lions, and thirteen years of BBC television.
If you watched Big Cat Diary, you already know Musiara Marsh. You may not know it is a real place you can stand in, a few hours from Nairobi, and that the descendants of the lions you watched are still there.
Where is the Marsh Pride?
Musiara Marsh, at the northern end of the Maasai Mara National Reserve. Governors’ Camp and Little Governors’ sit closest to their territory.
The marsh is fed by springs, so it holds water when the plains around it dry out. That is the whole reason the pride exists where it does. Game comes to water, and lions follow game.
It is also why the pride has been filmable for four decades. They are not wandering across a thousand square kilometres. They are anchored to a wet place in a dry country.
How the pride became famous
Big Cat Diary ran on the BBC from 1996 to 2008, and made individual Mara lions into household names across Britain.
The pride had been watched long before that. Brian Jackman and Jonathan Scott published The Marsh Lions in 1983, after five years following the pride and its descendants. Scott went on to present the television series that turned them into celebrities.
What made it work was the naming. Once an animal has a name and a history, viewers stop watching a species and start following a family. That is a rare thing in wildlife broadcasting and it is why the audience never really let go.
The lions people remember
Names From The Marsh
| Scar and Scruffy | Held the marsh from 1998. In 1998 a buffalo herd charged into the pride and killed cubs. Scruffy stood his ground. Scar ran. Scruffy was killed by herders the following year. |
|---|---|
| Simba | Held the pride from around 2000 to 2003. |
| Notch | Took control in 2004, lost his coalition partner to rival males, and held the pride alone for a remarkable stretch before being pushed out in 2007. |
| The Notch coalition | After his defeat, Notch left with his five adolescent sons. Together they built a territory across Mara North reported at over a thousand square kilometres, one of the most successful coalitions ever recorded in the Mara. |
| Charm | The matriarch who carried the pride through its hardest years, and who appeared in the BBC series Dynasties. |
Notch is the name Mara guides still measure other lions against. Ask a guide who started his career in the mid 2000s and you will get twenty minutes you did not plan for.
The poisoning of 2015
Eight lions were poisoned after feeding on a cow carcass laced with a carbofuran pesticide. Three died. Two herders were arrested.
This is the part of the story the television audience found hardest, and it is the part worth understanding, because it is not a story about villains.
The Mara is not fenced. Livestock and lions share the same ground, and a family that loses cattle loses its savings. Poison is cheap, available and indiscriminate. It kills the lion that took the cow, and then it kills the vultures and hyenas that feed on the lion.
Conservancies exist largely because of this. When landowners are paid a reliable lease income for keeping land open to wildlife, a lion becomes an asset rather than a threat. It is the single most effective conservation mechanism in the Mara ecosystem, and every night you spend in a conservancy pays into it.
Where the money goes. Conservancy fees are not a tax on your holiday. They are the lease payments that keep several hundred thousand acres of Maasai land open to wildlife instead of fenced and cultivated. Ask your operator which conservancy your bed night supports and how the lease is structured. It is a fair question and a good one.
Is the Marsh Pride still there?
Yes. The pride has continued through repeated changes of leadership, and their descendants hold territory across the northern Mara and the conservancies beyond it.
Lion prides do not end, they turn over. Females stay and inherit. Males arrive, hold ground for a few years, and are pushed out by the next coalition. The pride that Jackman and Scott watched in the late 1970s is not the same set of animals, and is entirely the same pride.
Notch’s bloodline in particular has spread widely through the ecosystem, and guides will point out coalitions descended from his sons across the northern conservancies.
The composition changes month by month, so we do not publish a current roll call here. Our guides in the Mara will tell you who holds the marsh in the week you arrive, which is the only version worth having.
Seeing them for yourself
Three practical things, from people who work there.
- Stay close to Musiara. Lions do most of their moving at dawn and dusk, and an hour of driving to reach their territory is an hour of the best light spent on a road.
- Take a private vehicle. Sitting with a pride for two hours is how you see behaviour rather than a sleeping cat. In a shared vehicle you leave when the others want lunch.
- Ask for a guide who was working in the Notch years. The Mara has guides who watched all of this happen. They are the difference between seeing lions and understanding them.
And a note on expectation. These are wild animals in an unfenced reserve. Nobody can promise you the marsh pride on a Tuesday. What we can promise is that you will be looking in the right place with someone who knows the family.
