Controversial Conversations about Conservation - Really?

Confrontation in conservation is nothing new. However, when do you know your actions "on the land" benefit many species beyond all reasonable doubt? The answers are often there staring us in the face, observed or heard (I am somewhat obsessed with bird songs and thereby songbirds) and show up in the gathered data. Controversy is just a mind state, with the reality of how we've assisted our most threatened species only delivered through conservation evidence.
