restoration-ecology
Restoration ecology is the science and practice of actively repairing ecosystems that have been degraded, damaged, or destroyed, returning them toward their natural structure and function. For plant scientists, it is a critical field because plants form the structural foundation of most ecosystems, meaning successful restoration hinges on reestablishing appropriate plant communities, soil-plant interactions, and seed dispersal networks. Research in this area informs which species to prioritize, how to overcome barriers like seed limitation or soil degradation, and how restored plant populations contribute to broader biodiversity recovery and climate resilience.

A study of Palmyra Atoll found that pisonia trees — the keystone rainforest species of remote Pacific islands — depend entirely on a specific group of fungi called Tomentella to survive the extreme nutrient conditions created by seabird droppings. Crab burrowing also boosts fungal diversity, suggesting animal activity shapes the hidden fungal networks that hold island ecosystems together.
Pisonia trees are obligately (exclusively) dependent on Tomentella fungi, which are uniquely adapted to survive the nutrient-extreme conditions caused by concentrated seabird guano.
Tomentella fungal abundance across the atoll was directly predicted by distance to pisonia trees, showing the fungi spread outward from their host.
Crab burrowing was associated with increased soil fungal diversity, including species that are new to science or globally rare.
