There always seem to be calls to expand the National Park System. And those calls always spur a number of questions.

Why does the National Park System need to be expanded? What sites might be considered for expansion? Can we even afford to expand the system? After all, as the Traveler frequently points out, the National Park Service doesn't have the resources in human capital or financial capital to properly manage the park units it has. There have been a number of stories recently in other news outlets about adding new national parks. But some of those simply point to existing units that are not officially called national parks, and why they should be renamed as national parks.

But is that really expanding the park system, or is it answering local chamber of commerce calls to rename the parks for economic benefit? Today we're going to dive into this topic with Elaine Leslie, who back in 2017 as chief of biological resources for the National Park Service, contributed to the National Park Service System Plan, charged with envisioning the growth of the National Park System.

Also in the conversation is Michael Kellett, who has spent roughly 40 years advocating for national parks, wilderness, national forests, free-flowing rivers and imperiled wildlife. Michael also is the co-founder and executive director of the New England-based conservation group Restore the North Woods. In that role he is director of the group's new national parks campaign, which is building a grass roots movement for New National Parks across the country.
