We wanted to identify best practices and policies which may be used to prevent sexual harassment from occurring in outdoor field laboratories in agriculture and natural resources higher education degree programs. We organized a focus group with ten experienced faculty members from American colleges and universities and asked participants to identify, discuss, and rate best policies and practices. The focus group participants deemed these items to be essential: (1) Enforce Title IX policies; (2) Set clear expectations for faculty and student behavior and enforce consequences for faculty and students who violate these expectations; (3) Establish a laboratory code of conduct which includes information about sexual harassment; (4) Create a laboratory climate with both open communication and zero tolerance for sexual harassment. It will take effort and self-education from faculty members to apply these recommendations to specific agriculture or natural resources laboratories, but implementation should reduce the risk of sexual harassment and create more inclusive learning spaces for all students.
