The fragmentation here is the inverse of the reforestation we saw in Foster's analysis of Petersham, Massachusetts. But that's because we (or I) focused on the forest ecosystem in Petersham, not the grasslands.

... affected.²

Did you notice how I slipped back into a species-centric focus here? That reflects the aspects of conservation that I tend to think about. Obviously, we could also concern ourselves with how fragmentation affects ecosystem processes or community structure/function, but that won't be my primary focus. They're important, but I know even less about them than I do about fragmentation effects on species. I am a population geneticist, after all.

... local populations.³

Of course, this assertion depends on how fragmentation affects the character of the matrix in which fragments are embedded, a point that we'll return to in a bit.

... plants⁴

Sorry for the plant-centric focus here, but it's what I know best and it's what I think is most scary.

Arguably, if you could, you'd be better off, for conservation purposes if not scientific ones, leaving it alone and managing it as a single, large reserve.
