California condors, which are found in Arizona, are an endangered species.

Announced changes to the Endangered Species Act (ESA) are expected to go into effect next month. The modifications will be prospective and apply to new additions in the endangered species list. Environmental groups are concerned about the changes, but some observers say the impact is most likely to be incremental.

One of those is attorney Paul Weiland, who is a former deputy U.S. Attorney in the Law and Policy section, Environmental and Natural Resources division of the Department of Justice.

The Show spoke with him about frustrations some landowners have experienced with the ESA.
