Can multi‐species plantings alleviate abiotic stressors to enhance Bald cypress restoration?
Restoration researchers and practitioners alike advocate for novel restoration approaches, informed by ecological theories and principles, to enhance the likelihood of meeting restoration goals. Forested wetland restoration has historically focused on creating abiotic conditions that support the tolerance thresholds of desired species, but the stress gradient hypothesis provides guidance for potential new strategies that use biotic interactions to ameliorate stressful abiotic conditions. In this study, we tested whether multi‐species planting approaches can be used to enhance the survival and growth of a target restoration tree species, Bald cypress, along multiple abiotic gradients. We conducted a fully factorial controlled greenhouse experiment which manipulated above‐ and belowground interactions between two species (Bald cypress and Soft rush), as well as light availability and depth of inundation. Our findings showed that co‐planting Bald cypress seedlings with Soft rush did not increase tree biomass production or growth metrics (e.g. stem height and leaf area) under any exposed stress combination. Importantly, we found that full‐sun irradiance negatively impacted functional traits associated with the tree seedlings' health and ability to photosynthesize. Our findings are important for consideration by practitioners as light is rarely the focus of wetland ecosystem restoration and degraded forested wetlands or restoration sites often have open canopies.
期刊介绍:
Restoration Ecology fosters the exchange of ideas among the many disciplines involved with ecological restoration. Addressing global concerns and communicating them to the international research community and restoration practitioners, the journal is at the forefront of a vital new direction in science, ecology, and policy. Original papers describe experimental, observational, and theoretical studies on terrestrial, marine, and freshwater systems, and are considered without taxonomic bias. Contributions span the natural sciences, including ecological and biological aspects, as well as the restoration of soil, air and water when set in an ecological context; and the social sciences, including cultural, philosophical, political, educational, economic and historical aspects. Edited by a distinguished panel, the journal continues to be a major conduit for researchers to publish their findings in the fight to not only halt ecological damage, but also to ultimately reverse it.
