Bernie WagonblastHostTell us a little bit more about what habitat connectivity is and how habitat connectivity has become such a large issue in the northeastern part of this country in particular.

Yeah, so habitat connectivity is all about the degree to which species can move about the landscape freely to do all the things they need to do to access different food sources, find mates, raise their young, and increasingly to adapt to shifting habitats as a result of warmer temperatures.

So, you know, a connected landscape allows that movement to happen between natural areas made up of cores and corridors and and across major barriers like roads.

We have the most intact remaining example of our forest type globally, and much of the rest of it has been converted or heavily fragmented.

Despite the fact that we're relatively well-connected and the millions of acres that we have conserved in the Northeast, we're still at risk of becoming like a series of ecological islands if we don't maintain the connections between our core forests.


It's, you know, the biggest and most resilient migration corridor in the east.

And so it's really critical that we maintain connections not only within the northern Appalachians, but also, you know, those connections to the central and southern Appalachians.

And I think there's also just a growing recognition that a connected landscape really benefits people in addition to nature.

You know, healthy connected lands and waters really provide us with clean air and drinking water and can help keep communities safer and adapt to increased flooding and other threats.
The Nature Conservancy has developed relationships with many of the state DOTs in the Northeast.
