It is now clear that the routine embedding of experiments into conservation practice is essential for creating reasonably comprehensive evidence of the effectiveness of actions. However, an important barrier is the stage of identifying testable questions that are both useful but also realistic to carry out without a major research project. We identified approaches for generating such suitable questions. A team of 24 participants crowdsourced suggestions, resulting in a list of a hundred possible tests of actions.Additional co-authors: Roger Mitchell, William H. Morgan, Roy Mosley, Silviu O.
