Evaluating methods for high‐resolution, national‐scale seagrass mapping in Google Earth Engine
Remote Sensing in Ecology and Conservation, Volume 12, Issue 2, Page 292-304, April 2026.Marine habitat mapping using satellite imagery can provide baseline and monitoring data across large spatial scales and in remote locations globally. This study evaluates how key methodological choices influence the accuracy of open‐source (for non‐commercial use), cloud‐based satellite mapping workflows for seagrass meadows in the Maldives.

Qualitative and quantitative photogrammetric techniques for multi-temporal landslide analysis
Annals of Geophysics, 2006 The results of two survey methods, geological photointerpretation and historical photogrammetry, are compared in order to evaluate the temporal evolution of a unstable slope located in the Tuscan-Emilian Apennines (Italy). Historical aerial photos of the

People and Nature, Volume 8, Issue 2, Page 283-300, February 2026.Abstract The Industrial Revolution triggered rural abandonment in Europe and had a profound impact on land configuration and ecosystem dynamics, mainly the growth of forests at the expense of open agricultural habitats. However, rural abandonment has been asynchronous in space and time, depending on regional socio‐economic dynamics.

Approche comparée de méthodes de classification d'images aériennes : une étude de cas [PDF]
Geographica HelveticaL'exploitation d'images aériennes ou satellitales à très haute résolution (< 5 m) remet en cause des procédures de Classification qui pourtant avaient fait leur preuve pour l'exploitation d'images à plus faible résolution.

Comparison of drone and ground surveys for the detection of a rare plant in a fragile ecosystem
Ecological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.We compared the accuracy, time, and financial costs of drone and ground surveys for the detection of wood lilies (Lilium philadelphicum) in an endangered alvar ecosystem. We found that the drone surveys detected 73%–78% of the plants found in the ground surveys, but that this type of survey was more expensive and time consuming than the ground survey ...

International Journal of Forestry Research, Volume 2026, Issue 1, 2026.Trees outside forests (TOFs) represent an important natural and anthropogenic resource that contributes significantly to biodiversity conservation, climate resilience, and the protection of forest genetic resources (FGRs). Despite their ecological and socioeconomic importance, TOFs are increasingly declining due to land‐use changes, urbanization ...
