Abstract: Ecological Restoration reverses habitat loss and destruction by promoting the establishment of native communities. Despite this, most restoration outcomes are notoriously unpredictable. Restoration practitioners need to make important decisions while restoring ecological communities and these decisions have lasting impacts on the outcome of the restoration. An important consideration in this enterprise is successful reproduction, which helps sustain populations over time. However, it is unclear how the restoration process influences plant reproduction. Reproduction is relevant at different organizational levels- individuals may exhibit differing fitness which affects evolutionary trajectory, while reproduction at the population level determines species persistence at different locations. In particular, managerial decisions regarding the richness and location sourcing of a seed mix are especially important in seed based restoration, such as Prairie ecosystems. These decisions play a disproportionate role in determining community composition, which ultimately has consequences for overall reproductive output. For example, seeds sourced from a distant location might produce individual plants that are maladapted and have faulty floral organs that reduce the number of seeds that can be produced. Additionally, higher initial seed mix richness may decrease seeding density and a plant population may be too small, sparse, or clumped for optimal reproduction to occur. In this study, we seek to answer the following question: How does initial seed mix richness and location sourcing affect plant reproductive output across different biological scales? To answer this question, we restored twelve experimental prairies in the Kellogg Biological Station, where we manipulated initial seed mix richness and the number of sources. We collected total plant and floral abundance data by counting the number of plants and flowers across various transects and collected the seed heads of nearly 400 senesced inflorescences of two dominant prairie forbs, Ratibida pinnata and Echinacea purpurea. We derived values that allowed the scaling our data, such as the number of inflorescences per plant, plant count per area, developed seed count per seed head, and more. We did not find a significant difference across our treatments & scales. Sites with that were sown with high richness and source treatments produced a similar number of seeds compared to sites with low richness and fewer sources. Despite this, sites with the low richness treatment had significantly more flowers. Our results suggest that manipulating seed mix richness and sourcing does not significantly affect reproductive output and recommend practitioners to opt towards cost-effective strategy of fewer species and number of sources.
