<jats:p> Environmental nongovernmental organizations (ENGOs) need resources in order to mount campaigns and ensure their stability over time. What is the most effective strategy to attract these resources? Building upon research on social movement strategy and resource mobilization, we examine how a diversity of income sources, tactics, and issue focus affects three measures of mobilization outcomes: income, staff, and members. We examine these relationships using a unique panel data set of ENGOs in the UK collected by the Environmental Funders Network in 2013 and 2016. Our analyses show that using a more diverse range of tactics in wave 1 is associated with mobilizing more staff and members in wave 2. However, there is no significant penalty or payoff for groups that engage in issue or income diversification. We argue that diversifying tactics benefits organizations by helping them accrue the necessary human resources required for environmental action. </jats:p>
