How dogs wearing backpacks are helping to rewild an English woodland

Lewes, England — In an urban nature reserve in a small town about two hours south of London, you'll find the Lewes Railway Land urban nature reserve teaming with life — including a lot of humans and their companions.

"We get lots of people come onto the reserve — which we want — lots of dog walkers," Dylan Walker, with the Railway Land Wildlife Trust that manages the green oasis, told CBS News. "Inevitably, that has an impact on the habitat."

After years of heavy use, the reserve has suffered a little for its popularity, losing some native plant species. But Walker is hoping to bring that biodiversity back.
