National valuation of monarch butterflies indicates an untapped potential for incentive-based conservation

Abstract

The annual migration of monarch butterflies ( Danaus plexippus ) has high cultural value and recent surveys indicate monarch populations are declining. Protecting migratory species is complex because they cross international borders and depend on multiple regions. Understanding how much, and where, humans place value on migratory species can facilitate market‐based conservation approaches. We performed a contingent valuation study of monarchs to understand the potential for such approaches to fund monarch conservation. The survey asked U.S. respondents about the money they would spend, or have spent, growing monarch‐friendly plants, and the amount they would donate to monarch conservation organizations. Combining planting payments and donations, the survey indicated U.S. households valued monarchs as a total one‐time payment of \$4.78–\$6.64 billion, levels similar to many endangered vertebrate species. The financial contribution of even a small percentage of households through purchases or donations could generate new funding for monarch conservation through market‐based approaches.

Highly mobile seabirds reveal areas of conservation importance across the Atlantic Ocean

Countries have committed to expanding the marine protected area (MPA) network to 30% of the world's ocean by 2030, more than tripling current coverage, and focusing on areas important for biodiversity. For such expansion to translate into effective conservation of marine biodiversity, it must rely on the best available knowledge. Here, we analyze tracking data on > 13,000 individuals (44 species, eight families) to map the distribution of highly mobile seabirds in the Atlantic Ocean and adjacent seas throughout the year. We identify regions important year-round or seasonally. The High Seas are as important as national waters for highly mobile seabirds but are even less protected. Current Atlantic MPAs hold < 14% of tracked species density, but their expansion to 30% of the ocean could protect up to two thirds. We share this new knowledge layer to support national and international efforts and policies to strategically expand the Atlantic MPA network.

Ecological costs of waiting to restore ecosystem engineers: The case of giant tortoises in the Galapagos Islands

In the Galápagos Islands, giant tortoises ( Chelonoidis spp.) engineer terrestrial ecosystems. Endemic tortoise lineages have been lost from Floreana and Pinta Islands, resulting in ecosystem shifts, with tortoise population restoration currently being considered using hybrids that include ancestry from the now extinct C. niger of Floreana Island. We combined long-term vegetation monitoring with simulation of vegetation responses to tortoises, and tortoise translocation scenarios to assess whether using C. niger hybrids as ecological replacements on Pinta Island could restore ecosystem function without compromising restoration on Floreana Island. Woody plants have increased by >100% on Pinta Island between 2011 and 2022 in the absence of ecologically effective numbers of tortoises, but re-establishment of tortoises at a moderate density (0.7 tortoises/ha) could reverse those trends and delay restoration on Floreana Island by ca. one decade while preventing continued ecosystem degradation on Pinta Island. We demonstrate the feasibility of restoring ecological replacements and the importance of rewilding ecosystem engineers before ecosystem shifts become irreversible.

Simulating demography, monitoring, and management decisions to evaluate adaptive management strategies for endangered species

Adaptive management (AM) remains underused in conservation, partly because optimization-based approaches require real-world problems to be substantially simplified. We present an approach to AM based in management strategy evaluation, a method used largely in fisheries. Managers define objectives and nominate alternative adaptive strategies, whose future performance is simulated by integrating ecological, learning and decision processes. We applied this approach to conservation of hihi (Notiomystis cincta) across Aotearoa-New Zealand. For multiple extant and prospective hihi populations, we jointly simulated demographic trends, monitoring, estimation, and decisions including translocations and supplementary feeding. Results confirmed that food supplementation assisted recovery, but was more intensive and expensive. Over 20 years, actively pursuing learning, e.g., by removing food from populations, provided little benefit. Recovery group members supported continuing current management or increasing priority on existing populations before reintroducing new populations. Our method can complement formal optimization-based approaches and improve AM uptake, particularly for programs involving many complex and coordinated decisions.
