Defining large‐scale arid island vegetation recovery targets through evaluating a reference ecosystem within an archipelago extent
Island ecological restoration presents challenges in establishing historical frames and reference ecosystems. Our study takes place in the Galapagos Islands and focuses on North Seymour (NS), recognized as a reference ecosystem for Baltra Island, which has suffered significant degradation. We assessed NS's arid plant community, comparing it with early twentieth‐century records. A first survey identified that dominant woody species on NS include native Bursera graveolens, Cordia lutea, Castela galapageia, Parkinsonia aculeata, and Opuntia echios, while Cleome viscosa is the only exotic species registered. A second survey divided both islands into evenly distributed plots, recording adults and juveniles of the five dominant species from the first survey. NS showed a structured community with higher species richness and density compared to Baltra. Castela galapageia prevailed in disturbed areas on Baltra. Juvenile regeneration was scarce on both islands. NS exhibited high species richness throughout, while Baltra had only two areas with similar high richness. Co‐occurrence analysis revealed significant associations between P. aculeata and B. graveolens on both islands. However, Baltra's network displayed missing links, indicating the need for restoration efforts. In conclusion, the structured plant community of NS can serve as one of the reference ecosystems needed for framing a restoration model for Baltra.
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.
