Evidence That Nature Reserves Help Endangered Species

[chaos_dream]

I was just wondering if anyone could cite any instances of actual evidence that nature reserves improve population growth rates/increase population numbers?
I'm writing a report for my biology degree and need some facts to back up my proposal.

I don't really mind what organism it's in reference to but large carnivores would be great

thanks!

You need proof that having nature reserves discourage hunting and poaching?

that's like asking for stats that people with umbrellas get rained on less than people without..
