Conservation status and protection measures for the Spanish endemic plant Sideritis borgiae Andrés

SummaryWe revise and update the records of strict and near-endemic species of Mt Kupe, Cameroon respectively from 31 strict endemics in 2004, to 25 today, and with near-endemic species 30, unchanged in number but with turnover. The changes result from new collections, discoveries and taxonomic changes in the last 16 years. While 15 of the provisionally named putative endemic species have now been formally published, a further 18 have not. The majority of the 30 near-endemic species (18) are shared with the adjacent Bakossi Mts, far exceeding the numbers shared with the more distant Mt Etinde-Mt Cameroon, Rumpi Hills and Ebo forest areas (sharing three near-endemic species each with Mt Kupe). We test the hypothesis that a further one of the provisionally named putative Mt Kupe species, Vepris sp. 1 from submontane forest near the summit, is indeed new to science. We compare it morphologically with the two other bicarpellate high altitude Cameroon Highland tree species V. montisbambutensis Onana and V. bali Cheek, concluding that it is a new undescribed species here named as Vepris zapfackii. The new species is illustrated and its conservation status assessed as Critically Endangered using the 2012 IUCN standard, due to habitat clearance from agricultural pressures at its sole location which is unprotected. Vepris zapfackii and V. bali appear unique in African trifoliolate species of the genus in having opposite leaves. Vepris zapfackii differs in having hairy petiolules and midribs and petiolules with the blade decurrent distally, narrowing towards a winged-canaliculate base (vs glabrous and petiolule long, terete), and sparsely golden hairy pistillodes and a glabrous calyx (vs densely black hairy pistillodes, and sepals hairy).

Characteristic Species

The sessile oak forests found on the northeast of the Iberian Peninsula are ascribed to the Lathyro-Quercetumpetraeae association and play a key role in understanding the ecology of this habitat, as this region represents its xeric limit. For this reason, we analysed the biodiversity patterns and current conservation status of the sessile oak forests in the region. To do so, we collected Braun-Blanquet inventories of 34 plots randomly distributed throughout the sessile oak forests. The results showed a relationship between the climatic conditions and the biodiversity variables. While the richness of the community increased with decreasing temperatures, the characteristic species found within the community decreased at these same temperatures. This result was due to the presence of most companion species in the cool zones at high elevations.Sessile oaks are found close to other communities, such as silver birches and Scot pine forests.On the other hand, in the warm areas at low elevations, the sessile oak community was more established, with plants typical of this type of forest. These slightly warmer zones with sessile oaks are very important in terms of conservation and more vulnerable to climate change and the thermophilization of the community, as has been studied. As such, protecting and managing these forests is key to conserving this community. Nevertheless, as current protection measures do not safeguard most of these forests, it is essential to define a conservation strategy to preserve them. Using the conservation status, we have established criteria to improve the conservation strategy for sessile oak forest on the NE Iberian Peninsula.

A New Species

The Chimanimani Mountains, located at the Mozambique-Zimbabwe border, are geologically unique in that they consist of quartzites giving rise to peaks and outcrops between zones of schist supporting grasslands. The nutrient-poor quartzitic soils house a high number of endemic plant species. One of these is Sericanthe chimanimaniensis, which is here described as new for science. We give a detailed description and distribution map, illustrations, information on ecology and phenology, and an assessment on the conservation status. An identification key to closely allied species is presented.

AbstractThe plant Mollinedia stenophylla Perkins (Monimiaceae) is endemic to southern Brazil and, until 2015, had not been seen for 122 years. We located a single population of the species on the margin of a watercourse in the mountainous region of Rio de Janeiro state. We describe the location of the species, comment on its morphology, ecology and conservation, assess its conservation status, propose conservation measures, and discuss the potential value of local action plans for this and other narrow endemic plant species. Mollinedia stenophylla has whorled leaves, clonal reproduction and a low height, unusual traits in the genus Mollinedia. Using the IUCN Red List criteria we assess the species as Critically Endangered. This example highlights the importance of investing time in plant surveys and taxonomy, especially in megadiverse countries such as Brazil.

Area Of Occupancy

Thought to be endemic to the Commonwealth of Puerto Rico, Ruehssia woodburyana (Apocynaceae) was recently discovered at a single location on Norman Island in the British Virgin Islands. Despite an increase in the extent of occurrence and area of occupancy, this species meta-population is very limited with a total of 37 individuals known in the wild. The largest subpopulation, on Mona Island, has only 26 individuals. The species suitable habitat is experiencing a continuing decline due to urban development, grazing by feral ungulates and human-induced forest fires. Conservation action is urgently needed and should be directed towards establishing genetically representative ex situ collections, such as seed for long term storage and live material for propagation. This species is evaluated as Critically Endangered (CR), based on Criteria C2a(i)+D, according to the IUCN Red List Categories and Criteria (version 3.1) and guidelines (Subcommittee IUCN Standards and Petitions 2016). Extensive and regular surveys to the region enable the discovery of new plant records for different countries and islands. In this paper, we record a new island record for Ruehssia woodburyana on Norman Island, in the British Virgin Islands and discuss the species conservation status. Marsdenia woodburyana is transferred to the genus Ruehssia to reflect the resurrection of that genus for species of Marsdenia native to the New World.

Abstract Eryngium viviparum (Apiaceae) is an endangered endemic plant of the Atlantic region of Europe, growing in seasonally flooded sites, and is characterized by a highly disjunct distribution. It occurs in just a few sites in the north-western part of the Iberian Peninsula and in a single locality in France. To improve the conservation status of E. viviparum in France, a conservation programme has been implemented to reintroduce the species. Before considering such an operation, genetic studies were conducted to determine the genetic status of the last French population and to identify the genetic source that should be considered for the best reintroduction strategy. Using microsatellite markers, we documented the genetic structure of the last French population and compared its genetic diversity with that of ten Iberian populations, which cover the three geographical regions where the species occurs. As expected, the French population of E. viviparum shows low genetic diversity due to a bottleneck and geographical isolation. The evolutionary potential appears low, with no private alleles in this population. Furthermore, this population is highly differentiated from the Iberian populations in terms of genetic variation and ecological niche. These results bring new questions regarding the conservation of E. viviparum in France, especially for management and reintroduction aimed at favouring genetic diversity and avoiding extinction.

Number Of Individuals

ABSTRACT Astragalus bozakmanii Podlech, an endemic plant species to Turkey, was investigated to provide an understanding the conservation status of this species and to fill the gap in the knowledge of habitat of this species. Field studies were carried out randomly by sampling 2 × 2 m sizes, 10 quadrats from each region. The number of individuals was estimated by calculating the average individual numbers in small quadrats and extrapolating this result for approximate population area. Reproductive success was evaluated using the mean number of seeds per fruit and the number of ovules per flower. A. bozakmanii prefers saltless soils whose pH values range from 7.48 and 8.33. The seed set was 45.8% of the ovules. In this study, we observed that the flowers of A. bozakmanii were visited by Oxythyrea cinctella to feed on their reproductive parts, thus rendering them infertile. Considering all these findings, the global and national conservation status for Astragalus bozakmanii was assessed as Endangered (EN) B1ab (i, ii, iii) + 2ab (i, ii, iii) according to the new IUCN Red List criteria. In conclusion, appropriate conservation actions need to be developed so that natural enemies of agricultural pests can re-enter their habitats.

Endangered Status

AbstractThe aims of this work were to verify the distribution and population size of Lamyropsis microcephala (Asteraceae), characterize its habitat, assess its conservation status and initiate conservation measures for this Critically Endangered species. Distribution was determined by field surveys and mapping. To estimate population size and density 81 permanent monitoring plots were randomly established. Ex situ conservation measures were activated by harvesting and appropriate storage of seed. We confirmed the presence of L. microcephala at two previously known sites and found it in two previously unknown localities. The areas in which the species occur vary from 200 to 240,000 m2, at altitudes of 1,450–1,820 m, on slopes of 15–45° with aspects from north to west. The estimated number of ramets per population varied from c. 2,000 to c. 2,000,000, with a mean density of 8.29 ± SD 14.3 to 10.33 ± SD 10.05 ramets m-2. Our findings confirmed the Critically Endangered status of this species, although with different criteria. This study is an example of an integrated approach for the conservation of an extremely narrow endemic plant species and may be useful for other little-known threatened species for which urgent conservation measures are needed.
