Ben Kessler, a student at the University of North Texas and an environmental activist, was more than a little surprised that an FBI agent questioned his philosophy professor and acquaintances about his whereabouts and his sign-waving activities aimed at influencing local gas drilling rules.

“It was scary,” said Kessler, who is a national organizer for the nonviolent environmental group Rising Tide North America. He said the agent approached him this past fall and said that the FBI had received an anonymous complaint and were looking into his opposition to hydraulic fracturing, also known as “fracking.” The bureau respected free speech, the agent told him, but was “worried about things being taken to an extreme level.”

Even as environmental and animal rights extremism in the United States is on the wane, officials at the federal, state and local level are continuing to target groups they have labeled a threat to national security, according to interviews with numerous activists, internal FBI documents and a survey of legislative initiatives across the country.Iowa Gov. Terry Brandstad (R) signed a law this month, backed by the farm lobby, that makes it a crime to pose as an employee or use other methods of misrepresentation to get access to operations in an attempt to expose animal cruelty. Utah passed a similar bill, nicknamed an “ag-gag” law, on Wednesday. Last month, Victor VanOrden, an activist in his mid-20s, received the maximum sentence of five years in prison under a separate Iowa law for attempting to free minks from one of the state’s fur farms.At the same time, though, acts that might be defined as eco-terrorism are down. In recent years, the broad definition has included arson, setting mink free at fur farms, campaigns to financially bankrupt animal testing firms and protests in front of the homes of some of those firms’ executives.  Michael Whelan, executive director of Fur Commission USA, estimated that in the 1990s “there were close to 20 attacks per year on our farmers” and that since 2003 there have been fewer than two attacks a year on American mink farms.

“Overall we’ve seen a decline in activity, in terms of violent criminal activity,” FBI intelligence analyst Erin Weller said in an interview.

FBI officials say two factors contribute to the reduced threat.

One is their successful prosecutions of several activists, in particular the 15 convictions in 2007 for members of the Earth Liberation Front. The national sweep of radical environmentalists was chronicled in the Oscar-nominated 2011 documentary “If a Tree Falls.” Not only did several ELF members get long prison sentences — Stanislas Meyerhoff got 13 years — but also many activists testified against others to get lighter punishments.

“That’s had an impact on the movement as a whole,” Weller said.

The second factor is that environmental and animal rights activists may view a Democratic administration as more sympathetic to their goals and be less inclined to take radical steps.

“Obviously if you think there is going to be support for your position, you’re going to use legal means rather than illegal means,” Weller said.
