Book Description

Federal and tribal lands on the U.S. borders with Canada and Mexico are vulnerable to illegal cross-border activity. The Department of Homeland Security (DHS), through its U.S. Customs and Border Protection's Office of Border Patrol (Border Patrol), is responsible for securing these lands, while the Departments of the Interior (DOI) and Agriculture (USDA) manage natural resources and protect the public. GAO was asked to examine the extent that (1) border security threats have changed on federal lands; (2) federal agencies operating on these lands have shared threat information and communications; and (3) federal agencies have coordinated budgets, resources, and strategies. GAO reviewed interagency agreements and threat assessments; analyzed enforcement data from 2007 through 2009; and interviewed officials at headquarters and two Border Patrol sectors selected due to high volume of illegal cross-border activity (Tucson) and limited ability to detect this activity (Spokane). GAO's observations cannot be generalized to all sectors but provide insights. This is a public version of a sensitive report that GAO issued in October 2010. Information that DHS deemed sensitive has been redacted. GAO is recommending that DOI and USDA determine if more guidance is needed for federal land closures, and that DHS, DOI, and USDA further implement interagency agreements. DHS, DOI, and USDA concurred with the recommendations.
