Environmental activism organizations depend on recruiting and retaining individuals willing to engage in leadership tasks on a voluntary basis. This study examined the resources which help or hinder sustained environmental volunteer activist leadership behaviors. Interviews with 21 environmental volunteer activist leaders were analyzed within a Resource Mobilization Theory framework. While six resources supporting sustained engagement in volunteer activist leadership behaviors were identified, only three were sought by all participants: time, community support, and social relationships. Money, volunteers and network connections were considered valuable resources, however their acquisition generated significant additional administrative burdens. Social relationships sustained volunteer activist leaders through fostering feelings of positive emotions connected with the group. We conclude with suggestions for organizations seeking to increase retention of activist volunteer leaders: namely larger organizations sharing their resources to reduce administrative demands on volunteer activist leaders in smaller organizations; developing movement infrastructure groups to build and sustain networks; and the prioritization of positive relationships within volunteer teams.
