Next week on the Exchange: We talk with wildlife experts, including a veteran moose biologist, about the steep decline in New Hampshire’s moose population. We’ll find out how New Hampshire plans to tackle the issue. We’ll also look at how the state plans to go about regulating and dispensing marijuana now that a compromise medical marijuana bill, minus the home-grown option, has been signed into law. We’ll spend two days looking at the latest on invasive species of the plant and animal varieties and don't forget about our Friday New Hampshire News Roundup.
