I was thinking the same thing. Let's see, we increase the population percentage wise by restricting boating and GOK what else. Let me try some numbers: Population up from 300000 to 400000 during the "study period". Deaths up from 1000 to 1200, a shocking 200, a shocking 20%. We better restict boating! Never mind 1000 deaths on 300000 is 3.33% and 1200 on 400000 is a shocking-oops-we-better-not-publish-this 3.00%... That might indicate with deaths DOWN 30% that conservation was already doing just fine.
