“…A geographically distinct portion of the species range occurs on the Yucatán Peninsula (México), where at least two genetically distinct populations (King et al, 2005; King et al, 2015; Noreña‐Silva, 2019; García‐Enríquez et al, 2023; Zamora‐Bustillos et al, 2023; Noreña‐Silva et al, in review) persist along the western and north‐eastern coasts, respectively. Three spatial units were defined to account for variations in ecological features, potential genetic structure and threats on the Yucatán Peninsula.…”

“…The Northern Yucatán spatial unit also contains protected habitats, notably in the Ría Lagartos Biosphere Reserve, Yalahau Coastal Lagoon (Yum Balam Federal Wildlife Protection Area) and embayments in the Cabo Catoche Wetland System (Table 1). Genetic and tagging data indicate substantial gene flow between sites and migrations between embayments along the north‐western, northern, and eastern coasts and the continental shelf (Noreña‐Silva, 2019; García‐Enríquez et al, 2023; Zamora‐Bustillos et al, 2023; Noreña‐Silva et al, in review). The Eastern Yucatán spatial unit combines pristine habitats in the Chacmochuch Coastal Lagoon to the north and the Sian Ka'an Biosphere Reserve lagoon systems to the south with the highly developed Cancún (Nichupté Lagoon System) and Mayan Riviera regions in between (Table 1).…”

According to an International Union for Conservation of Nature (IUCN) Red List assessment (RLA), the American horseshoe crab (Limulus polyphemus), an iconic coastal species, is at risk of extirpation in some regions within its range where small and vulnerable populations occur. However, the RLA does not consider future status beyond viability and does not attempt to identify the conservation necessary to effectively mitigate threats and recover the species to full ecological functionality. To aid in conservation planning for vulnerable species, the IUCN developed the Green Status of Species assessment (GSA) process to complement the RLA. This paper describes the application of the GSA process to assess the recovery potential of the American horseshoe crab. First, specific Limulus populations within spatial units for conservation were delineated, and their statuses were defined based on viability and ecological functionality. Then conservation actions were identified that would promote recovery and affect their near‐ and long‐term population status under different conservation scenarios. Horseshoe crab conservation has relied on, and will continue to depend on, effective harvest regulation. However, as currently conceived, conservation is not expected to mitigate habitat loss at the scale required to restore range‐wide ecological functionality, primarily because habitat loss is widespread and affected by climate change. Thus, the GSA results, while indicating that there is potential for near‐term recovery gains, reveal that long‐term recovery is in doubt owing to expected loss of habitat. To conserve critical habitats for spawning and early life stages and achieve ecological functionality, it is imperative to identify and develop conservation plans at appropriate spatial scales. Unfortunately, such plans do not currently exist and need to be established. The GSA Green Score can then serve as a metric for monitoring recovery and gauging the effectiveness of conservation implementation.
