This episode of the Beyond Data Podcast (Season 1, episode 3) was originally released in August 2018.
The non-native brown trout, which the data show places a burden on imperiled native fishes, is revered in the United States, while other non-natives are demonized. In this episode of the Beyond Data Podcast, we take a deep dive into the interplay between non-native and native fishes–especially salmonids. We’ll look at how our perceptions toward introduced species are shaped, and we’ll ask the question of whether or not there is a place for non-native species in ecosystems we consider healthy.

About the Beyond Data Podcast
For the past decade Beyond Data Podcast host Ret Talbot has been a freelance journalist and science writer reporting on fisheries at the intersection of science and sustainability. He frequently uses the hashtag #datamatter because, well, they do. But what happens when the data simply don’t exist, are insufficient or unavailable? What happens when so-called alternative facts are considered just facts and people operate under the impression that the plural of anecdote is indeed data? How do we reach consensus when everyone espouses his or her own data—his or her own facts? In the Beyond Data Podcast, Talbot and his guests go where he’s often been unwilling to go in his reporting–beyond data.
