Encore: How I came to work with the lions who live in trees

It's a very, very good question.

Conversations
Encore: How I came to work with the lions who live in trees

And the reason that it's a very good question is because

Conversations

the counting mechanism that we use, one of the parameters is called detection probability.

Conversations
Encore: How I came to work with the lions who live in trees

What is the likelihood that you see a lion in a landscape?

Conversations
Encore: How I came to work with the lions who live in trees

And as you can imagine, with a lion that's sitting in a tree, you're driving around and suddenly, boom, from 150 meters, you see a tail hanging out of a tree.

Conversations
Encore: How I came to work with the lions who live in trees

So for that reason, you are seeing them with a very high likelihood.

Conversations
Encore: How I came to work with the lions who live in trees

But that in of itself is this weird, it's kind of like it's deceptive because you're seeing them with such a high frequency.

Conversations
Encore: How I came to work with the lions who live in trees

So you think there's a lot, but actually you're seeing the same individual over and over and over again.

Conversations
Encore: How I came to work with the lions who live in trees

So you have to dissect those two things away from each other.

Conversations
Encore: How I came to work with the lions who live in trees

We do.

So we're about to publish our national census report with the Uganda Wildlife Authority.

Conversations
Encore: How I came to work with the lions who live in trees

So the count that we did in 2018 showed that there was roughly 72 individuals left in a 2,500 square kilometer area, which is a pretty small population.

Conversations
Encore: How I came to work with the lions who live in trees

So to give you an idea, 2,500 square kilometers is about the size of the Maasai Mara, which is probably the most iconic lion population anywhere in Africa, anywhere on planet Earth.

Conversations
Encore: How I came to work with the lions who live in trees

And there you have about 400 lions.

Conversations
Encore: How I came to work with the lions who live in trees

living at a density of about 17 individuals per hundred square kilometers.

Conversations
Encore: How I came to work with the lions who live in trees

This is about an eighth of that.

Conversations
Encore: How I came to work with the lions who live in trees

So this is showing you that although this is an incredibly iconic special population that's doing this wonderful behavioral thing that's bringing in a lot of tourists, they're severely threatened.

Conversations
Encore: How I came to work with the lions who live in trees

So the biggest thing that we need in populations of wildlife, especially wild cats, is we're always interested in the females.

Conversations
Encore: How I came to work with the lions who live in trees

The females are really the lifeblood of any population.

Conversations

And the reason the females are so important is
