“…from adjacent slash and burn agriculture, colonisation by non-indigenous species such as Ananas comosus L., which can out-compete indigenous inselberg species and replace them. Inselbergs are extensively targeted and quarried for their granite, which converted to gravel is in high demand for production of concrete and road surfacing and which can totally destroy the inselbergs concerned in terms of their plant communities (Couch et al 2019).…”

SummaryWe describe two range-restricted new species to science from the genus Impatiens (Balsaminaceae), both threatened, from lowland of the Cross-Sanaga Interval of western Cameroon. The first, Impatiens banen, appears to be restricted to an open seepage microhabitat on granitic inselbergs in the lowland-submontane forest zone of the Ebo Forest in Littoral Region and is provisionally assessed using the 2012 IUCN standard as Vulnerable. Sharing characters with Impatiens burtonii and I. mannii, it differs from both, and appears to be unique in Cameroon inter alia 1) in the bicolored united lateral petals, the upper petals being white, while the lower petals are an intense pink-purple, 2) the hairy, filamentous spur, purple with a white apex, is curved along its length, almost describing a circle. Inselberg-specific species are unusual in Impatiens.The second species, Impatiens etugei, of the I. macroptera aggregate, is restricted to rocks in the Mutel River of the Kom Wum Forest Reserve of North West Region and is assessed as Critically Endangered. Having similarities with I. mackeyana and I. letouzeyi, it differs from other species in the aggregate inter alia by having opposite leaves (vs always alternate), flower exterior white (vs pink or pink-purple), and in the dorsal petal having a pair of lateral projections (vs projections absent).

“…Outside Europe there are some examples in Malaysia (Hamidah et al 2020) and Saudi Arabia (Al-Abbasi et al, 2010), from which several lists of threatened and endemic plant species have been produced (Couch et al 2019a;Couch et al 2019b; Darbyshire et al 2019). In the Americas, the IPAs methodology has been mainly implemented in low-lands tropical ecosystems (i.e.…”

The Tropical Andes region harbors highly significant and threatened biodiversity areas. However, due to its misidentification, conservation initiatives in these regions are limited and need more substantial support. Identifying Important Plant Areas (IPAs) offers a valuable methodology for establishing conservation priorities, a particularly complex task in a mega-biodiverse region such as the Andean tropics. Due to its iconic recognition and conservation value, this study focused on the Espeletiinae subtribe (Asteraceae) as a reference group, and we compiled species distribution data for 138 taxa from 5,560 georeferenced records. Using the IPA, we divided the study area into 220 Units of Analysis (UA) represented by 10 × 10 km plots. Refined distribution areas, incorporating richness, threatened species, and ecosystem-based richness distributions, were analyzed using newly generated maps. Most UAs were concentrated in Colombia's Eastern Cordillera, extending into Venezuela. Our analysis identified 176 UAs using sub-criterion cA1 (with 59 species) and 51 UAs using sub-criterion cB (with 76 species). We classified 11 UAs as high-priority, 58 as medium-priority, and 143 as low-priority, highlighting the IPAs that require focused conservation efforts. Key findings from our study include: i) the first regional-level application of IPA methodology; ii) the potential of implementing criteria A and B to support global biodiversity recovery targets; and iii) the suitability of Espeletiinae as a focal group for systematic conservation planning in the region. Accordingly, we consider that our results establish a spatial planning procedure and analytical tool for decision-makers to guide conservation management and actions across the tropical Andean region.

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.
