The pro bono contributions of lawyers at three major Florida-based firms decreased sharply last year, while contributions at a fourth major firm increased slightly, according to new data collected by The American Lawyer magazine and the Daily Business Review.

In their responses to the annual Am Law 200 survey, Akerman Senterfitt, Greenberg Traurig and Holland & Knight reported that the hours spent by their U.S. lawyers on pro bono work for indigent clients declined 14 percent to 16 percent from 2005 to 2006. Akerman and Holland also reported declines in the number of their lawyers who performed more than 20 hours of pro bono work last year.
