Summary: This study compared the effects of traditional livestock grazing and a system consisting exclusively of wild ungulates on landscape vegetation processes. The researchers also investigated the fine-scale changes in vegetation structure and functioning over time in a mountainous Mediterranean system using UAV flights and image processing. The results showed that high-resolution images provided important information on the spatial distribution and seasonal oscillation of small vegetation patches. The study also found differences in vegetation functioning between wild ungulates and livestock, and emphasized the importance of multi-temporal studies for understanding vegetation response to climate.

Summary: This study evaluates the skills of two types of drone-based point clouds, derived from LiDAR and photogrammetric techniques, in estimating ground elevation and vegetation characteristics on a salt marsh. Results show that LiDAR-based techniques provide more accurate reconstructions compared to Digital Aerial Photogrammetry (DAP). The classification procedure for vegetation calculation negligibly improves when RGB images are used as input parameters with the LiDAR-UAV point cloud.

Summary: Salt marshes, being one of the most productive ecosystems, are facing threats from human activities and sea level rise. This study aims to differentiate and determine the distribution of plant species in salt marshes using a high-resolution hyperspectral imaging system onboard a UAV. The use of UAV-HS techniques is expected to improve our understanding of coastal ecosystem responses and increase our capacity to detect small changes in plant species distribution through monitoring.

Summary: With the increase in frequency and intensity of typhoons due to global warming, this study examined the damage caused by Super Typhoon Mangkhut to urban vegetation in Shenzhen, China. The use of UAV oblique photography technology was validated as an accurate and cost-effective method to assess the damage. The results showed severe damage to roadside trees and artificially landscaped forests, while the naturally occurring urban forest was less affected.

Summary: One of the key indicators for wetland restoration is whether it behaves hydrologically like a natural wetland. A study in Plymouth, Massachusetts, used a thermal infrared camera mounted on a drone to map groundwater seeps before and after wetland restoration. The analysis showed that restoration removed barriers to surface expression and successfully increased residence time, providing valuable insight into the impacts of restoration on groundwater expression.

Summary: Biogeomorphology is expanding as a discipline that explores the feedback between biological and geomorphological systems, with new processes and feedbacks still being identified and quantified. The main research challenge is to link ecological and geomorphic processes across different spatio-temporal scales, and to translate biogeomorphic knowledge into management approaches. Future studies should consider the ecology and size of organisms to contextualize environmental feedbacks, and longer-term monitoring and interdisciplinary approaches are expected to lead to important advances in process understanding and modeling.

Summary: Enhanced deposition near river mouths affects mangrove forests in the Mekong river delta, leading to forest dieback. The burial of sediment covers pneumatophores, decreasing the health of the mangroves. However, the study also shows that the forest partly recovers after a period of dieback.

Summary: Tidal marshes, including saltmarshes, provide significant value for social and environmental services, but are threatened by human development, invasive species, erosion, altered hydrology, and climate change. Restoration projects are like experiments, requiring clear goals, monitoring, and adaptive management practices. An important aspect is the need to establish a network of tidal marsh scientists, managers, and practitioners to share and disseminate new observations and knowledge.

Summary: This study describes the evolution of the lagoons in the Po Delta, Italy, and the historical changes of the salt marshes using historical maps and aerial data. The research reveals that most of the lagoons were formed between 1892 and 1934, with more recent developments between 1978 and 1988. The lagoons reached their current shape and dimensions by 1955. The analysis also shows that the Po Delta lagoons have experienced erosion and environmental degradation over the past 120 years.

Summary: A framework to estimate coastal vulnerability to flooding and erosion has been developed for the Ionian Basilicata coast. The results show that the integrated coastal risk is generally medium to high, while the physical erosion vulnerability is generally high to very high. Furthermore, the vulnerability exhibits spatial variability, possibly influenced by the beach morphology.

Summary: Marine litter is a global issue, and increasing citizen knowledge and awareness is important to address this problem. A study in North Sardinia analyzed the abundance of marine litter on 5 pocket beaches and found that plastic was the most prevalent category. The density of waste varied due to geomorphological control and human influences, highlighting the need for understanding debris fate, transport, and human behaviors.
