“…Other prioritisation schemes, such as Important Bird Areas, do not incorporate habitat-specific criteria, while Key Biodiversity Areas do have the criteria to include ecosystems but rely on global Red List of Ecosystem assessments (of global ecosystems or, at a broader scale, biogeographic ecotypes) that are yet to be completed (KBA, 2023; KBA Standards and Appeals Committee, 2020). IPAs, in contrast, have the flexibility to identify threatened and restricted habitats on a regional and national scale.…”

Important Plant Areas (IPAs) are a successful method of identifying priority areas for plant conservation. Assessment of IPAs, however, often relies on criteria related to species, while incorporation of habitats has been less consistent. Using Uganda as a case study, we test the application of the threatened habitat criterion (criterion C). We identified nationally threatened habitats using Red List of Ecosystems criteria and assess, for the first time, how differing application of thresholds under criterion C can influence IPA network outcomes. Eleven threatened habitats were identified, with declines switching from predominantly forest to savanna after the mid-20th century. Significantly, we found current IPA guidance on use of Criterion C needlessly limits the number of sites that qualify as IPAs. The five best sites threshold is reserved for countries where quantitative data is unavailable, however, the application of the relevant thresholds to quantitative data largely generated fewer than five IPAs, comparably limiting conservation opportunities identified. We recommend, therefore, that the five best threshold is available for application on both qualitative and quantitative data. This will bolster the value of IPAs in conserving and restoring threatened and ecologically important habitats under the Kunming-Montreal Global Biodiversity Framework.

1. There are growing pressures on marine biodiversity. Seabirds in particular are one the most-threatened groups. The black-vented shearwater (Puffinus opisthomelas) is endemic to Mexican islands and the only shearwater living its entire life cycle in the California Current System, one of the most productive large marine ecosystems in the world. Marine Protected Areas (MPAs) in this region, however, were designed without consideration of accurate data on seabird distributions.2. Here, 57 black-vented shearwaters were GPS-tracked from their main breeding colony (95% of the global population) over four seasons (2016)(2017)(2018)(2019) to estimate their at-sea distribution. Two methods were applied to identify priority conservation areas: the approach developed by BirdLife International to identify marine Important Bird and Biodiversity Areas and a method using expectationmaximization binary clustering to identify core foraging areas.3. One potential marine Important Bird and Biodiversity Area close to the breeding colony and five core foraging areas were identified. These priority conservation areas were largely beyond the bounds of the current MPA network in the region. 4. Our results detail opportunities for improving the implementation of conservation and management measures in the California Current System region with respect to seabirds. The approach of combining site identification methods can be applied to other seabird species for which high-resolution tracking data are available and can help guide conservation action plans and MPA design.

Background and aims The quartz fields of the Greater Cape Floristic Region (GCFR) are arid and island-like special habitats, hosting about 142 habitat-specialized plant species of which 81% are local endemics, characterized by a rapid turnover of species between and among sites. We use several phylogenetic community metrics to i) examine species diversity and phylogenetic structure within and among quartz fields; ii) investigate whether quartz field specialists are evolutionarily drawn from local species pools, while the alternative hypothesis posits that there is no significant evolutionary connection between quartz field specialists and the local species pools; and iii) determine whether there is an association between certain traits and the presence of species in quartz fields. Methods We sampled and developed dated phylogenies for six species-rich angiosperm families (Aizoaceae, Asteraceae, Crassulaceae, Cyperaceae, Fabaceae and Santalaceae) represented in the quartz field floras of southern Africa. Specifically, we focused on the flora of three quartz field regions in South Africa (Knersvlakte, Little Karoo and Overberg) and their surrounding species pools to address our research questions, scoring traits associated with harsh environments. Key results We found that the Overberg and Little Karoo had the highest level of species overlap for families Aizoaceae and Fabaceae, while the Knersvlakte and the Overberg had the highest species overlap for families Asteraceae, Crassulaceae, and Santalaceae. Although our phylogenetic community structure and trait analyses showed no clear patterns, relatively low pairwise phylogenetic distances between specialists and their local species pools for Aizoaceae and Fabaceae suggest that quartz species could be evolutionarily drawn from their surrounding areas, with phylogenetic overdispersion in Knersvlakte and Little Karoo for Aizoaceae and Crassulaceae. Conclusions Despite their proximity to one another within the GCFR, the studied areas differ in their species pools and the phylogenetic structure of their specialists. Our work provides further justification for increased conservation focus of these unique habitats under future scenarios of global change.
