Tilden’s South Park Drive will be closed to vehicle traffic from November 1 through April 1. Every year beginning in November, the road is closed to traffic for the seasonal newt migration. Thousands of newts rely on crossing the street as a means to reach Wildcat Creek for breeding. The newt is a type of salamander that is five to six inches long and a gold-bronze color. It remains dormant in the dry season living in woods and fields. With the arrival of rains, newts migrate to streams and ponds to mate.

Although not a threatened species, the overall newt population has decreased over the past several decades primarily due to loss of habitat. Road kill is a major contributor to adult mortality in areas with an urban wildlife interface. About ten years ago, the Park District took a proactive role in keeping newts thriving in Tilden Regional Park by closing the road. Visitors can still drive through the park by using Grizzly Peak Blvd., Wildcat Canyon Road and Central Park.

One benefit of closing the road is it provides opportunity for naturalist programs and nature hikes to observe this migration. Tilden Environmental Education Center offers many programs throughout the season. Walkers and cyclists (with care) can use the road keeping an eye out for newts. Please do not handle or remove them from their habitat. Newts can secrete a toxic substance from their skin that can cause great discomfort if that substance comes in contact with eyes or mouth. It can be fatal if ingested. If you accidentally come in contact with a newt you should always wash your hands and especially keep dogs away to avoid a costly visit to the vet.
