Bergamo, TF; Ward, RD; Joyce, CB; Villoslada, M; Sepp, K (2022-11-27)Coastal wetlands provide a range of important ecosystem services, yet they are under threat from a range of stressors including climate change. This is predominantly as a result of alterations to the hydroregime and ... -
From UAV to PlanetScope: Upscaling fractional cover of an invasive species Rosa rugosa.
Bergamo, TF; de Lima, RS; Kull, T; Ward, RD; Sepp, K; Villoslada, M (2023-06-15)Invasive plant species pose a direct threat to biodiversity and ecosystem services. Among these, Rosa rugosa has had a severe impact on Baltic coastal ecosystems in recent decades. Accurate mapping and monitoring tools are ... -
Global dataset of soil organic carbon in tidal marshes.
Maxwell, TL; Rovai, AS; Adame, MF; Adams, JB; Álvarez-Rogel, J; Austin, WEN; Beasy, K; Boscutti, F; Böttcher, ME; Bouma, TJ (Nature Research, 2023-11-11)Tidal marshes store large amounts of organic carbon in their soils. Field data quantifying soil organic carbon (SOC) stocks provide an important resource for researchers, natural resource managers, and policy-makers working ... -
