Dr. Sarah Mack of Tierra Resources studied black mangroves for their carbon sequestration potential and ability to combat marsh erosion through air-seeding. Wisner funded a two-year monitoring and feasibility study in December 2016, with a final report issued in June 2018. Based on the findings, Phase II was funded in June 2018, expanding the study to include new sites and erosion markers. Black mangroves were monitored after freezes in 2017 and 2018. In November 2019, the Tierra Foundation and 90 at-risk youth, collected propagules and air-seeded them. No air-seeding occurred in 2020 due to COVID-19, and efforts in 2021 were hindered by Hurricane Ida. Wisner funded $76,763.94, which was used as matching funds for a larger NFWF grant.
