Governments, communities, and the private sector implement a variety of conservation initiatives to prevent biodiversity loss. Emerging evidence suggests that many conservation initiatives scale up through similar temporal patterns, yet little is known about how initiatives spread across both space and time. Using a spatial statistical approach called space-time K function, we describe the spatiotemporal spread patterns of diverse conservation initiatives globally, including private land conservation, community-based natural resources management, and state-designated protected areas. We find that while some initiatives show clear spatiotemporal diffusion, i.e., a potential adopter is more likely to adopt a conservation initiative when their neighbors adopted previously, other initiatives do not exhibit trends. Qualitative review of initiative implementation suggests that both neighbor-to-neighbor interactions and program spatial prioritization could affect their spatiotemporal spread patterns. This research contributes to our understanding of how conservation goes to scale, which then supports the design and implementation of robust conservation initiatives.
