Experts are citing two major reasons for two separate cases of wildlife coming down from their habitats and wandering into the El Paso-Las Cruces area: drought and development.

The first case was a deer killed in the middle of the road by a driver in West El Paso. People said it's not the first time they've seen families of them wandering into neighborhoods. "We've had a family of deer that have walked up here on wildwood 4 or 5 of them. They were looking for vegetation. It was around midnight one night," said West El Paso resident Jay Butler.

Last Friday another case surface in Las Cruces when one family found a black bear on their property in one of their trees.

Experts said they're seeing more of these cases with wildlife coming face to face with civilization. It's a well known fact that during times of drought animals like bears and deer will wander larger distances to find food and water," said Ric LoBello, education curator at the El Paso zoo. He said it's not just drought but also development of new residential areas that is also forcing many animals out of their habitat.

LoBello said historically these animals had both high elevation and low elevation areas where they could range, but now the low elevation areas are prime real-estate sites and you see development starting to take over many arroyos near the Franklin Mountains. In West El Paso, the demise of the arroyos is stirring up controversy and opponents have put up signs upset with what's happening to wildlife.
