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 ...

Trait‐based species selection for restoration: A case study from tropical landscapes dominated by bracken

Journal of Applied Ecology, Volume 63, Issue 1, January 2026.
Our results can be used by stakeholders to select the species best suited for active restoration projects in bracken‐dominated areas throughout the tropical region. Furthermore, our trait‐based approach, which considers seedling performance in disturbed areas, can serve as a guide for species selection in restoration programmes in other disturbed ...

Disentangling seed availability and establishment filters at alpine treelines through a decade‐long field manipulation

Journal of Ecology, Volume 113, Issue 12, Page 3830-3844, December 2025.
Treeline advance under warming occurs only when multiple filters align—adequate seed supply, favourable microclimatic windows, moderated herbivory and shrub effects that remain facilitative rather than competitive. Abstract Climate warming is expected to increase upslope shifts of alpine treelines globally.
