The Balkan sub-endemic species Dactylorhiza kalopissii E. Nelson is distributed in Bulgaria, Greece and North Macedonia. It has a local distribution and inhabits alkaline fens, wet meadows, and mountain rivulet banks. This orchid is a globally endangered species, included in Annex IIb of the Council Directive 92/43 EEC. It was first reported for Bulgaria in 1991 and until 2008 it was known only from this single locality in the country. Here we summarize the recent data on the distribution of the species in Bulgaria, the population numbers and their fluctuation in time. During the period 2008 - 2019 the species was found in more than ten localities of six floristic regions. Populations usually number less than 250 individuals. For some of the populations, data from recurrent observations are provided. We discuss the habitats and their management. The negative changes of the habitat quality during the last years for some of the localities are described as well. The species was evaluated as CR B1ab (iii) + 2ab (iii) according to the Red List of Bulgarian vascular plants. We reevaluate the status based on the improved knowledge. The species is still Critically Endangered in Bulgaria, but В2ab (iii, v) status better corresponds with recent data. Five of the known localities fall within the boundaries of Natura 2000 SCIs.

The Marsh Gladiolus, Gladiolus palustris is a Central-European geoelement that extends its distribution to Albania, Bulgaria and North Macedonia at the Balkan Peninsula. It has a local distribution and inhabits marshes and wet meadows. It is included in Annex IIb of the Council Directive 92/43 EEC. There are insufficient data for its populations across the areal. Thus, it is considered as Data Deficient in the European Red List of Vascular Plants. Only singular, old dated reports existed for Bulgaria at the beginning of this century. More data were collected during the processes of designation of the Important Plant Areas and Natura 2000 SACs in the country (2004–2013). Here we summarize and discuss the data about the distribution in Bulgaria and the existing data for the known populations. Nowadays the distribution in two floristic regions (Pirin Mt. and Rhodope Mts.) is confirmed; there is no recent confirmation for the localities in other two regions (Rila Mt. and Slavyanka Mt.). Populations’ densities and numbers are highly variable, from less than 50 to thousands of individuals. We discuss the habitats and their management. The most important negative factor is the abandonment of the meadows.

AbstractThe co-extinction of parasitic taxa and their host species is considered a common phenomenon in the current global extinction crisis. However, information about the conservation status of parasitic taxa is scarce. We present a global list of co-extinct and critically co-endangered parasitic lice (Phthiraptera), based on published data on their host-specificity and their hosts’ conservation status according to the IUCN Red List. We list six co-extinct and 40 (possibly 41) critically co-endangered species. Additionally, we recognize 2–4 species that went extinct as a result of conservation efforts to save their hosts. Conservationists should consider preserving host-specific lice as part of their efforts to save species.

In The Wild

A recent complete assessment of the conservation status of 5487 mammal species demonstrated that at least one-fifth are at risk of extinction in the wild. We retrospectively identified genuine changes in extinction risk for mammals between 1996 and 2008 to calculate changes in the International Union for Conservation of Nature (IUCN) Red List Index (RLI). Species-level trends in the conservation status of mammalian diversity reveal that extinction risk in large-bodied species is increasing, and that the rate of deterioration has been most accelerated in the Indomalayan and Australasian realms. Expanding agriculture and hunting have been the main drivers of increased extinction risk in mammals. Site-based protection and management, legislation, and captive-breeding and reintroduction programmes have led to improvements in 24 species. We contextualize these changes, and explain why both deteriorations and improvements may be under-reported. Although this study highlights where conservation actions are leading to improvements, it fails to account for instances where conservation has prevented further deteriorations in the status of the world's mammals. The continued utility of the RLI is dependent on sustained investment to ensure repeated assessments of mammals over time and to facilitate future calculations of the RLI and measurement against global targets.

Assessment of plant species in particular rare and endemic is essential for monitoring and conservation planning. I aimed to support conservation activities by addressing knowledge of the status of Aloe dhufarensis Lavranos, one of the endemic plants in the Arabian Peninsula. Information on the status and distribution range of A. dhufarensis in the Arabian Peninsula is almost absent. To Assess A. dhufarensis according to IUCN categories, Extent of Occurrence (EOO) and Area of Occupancy (AOO) were created and measured using ArcMap 10.8. The species is described and illustrated; the distribution of the species was mapped. The evaluation and the conservation status of this plant species are reported according to the context of IUCN Red List guidelines and criteria.

Floristic Studies

Изучение разнообразия охраняемой флоры в заповеднике Нам Донг (северный Вьетнам) проведено в рамках флористических исследований территории в 2015–2019 гг. Исследование проводилось на семи профилях, заложенных от самых низких высот над уровнем моря до высшей точки изучаемой территории, с таким расчетом, чтобы максимально охватить возможное число местообитаний на склонах разной экспозиции. Флористические исследования позволили уточнить состав редких и охраняемых видов растений территории, имеющих международный или национальный природоохранный статус. К таким растениям в заповеднике относятся 88 видов (6,7% от всей местной флоры), принадлежащих к 51 семейству (28,3% от 180 семейств флоры). Охраняемые виды относятся к трем отделам сосудистых растений: Polypodiophyta – 5 видов (5,7%), Pinophyta – 10 (11,4%), Magnoliophyta – 73 (83,0%). Из них 57 видов занесены в список МСОП (IUCN), в т.ч. EN (исчезающие) – 7 (8,0%), VU (уязвимые) – 11 (12,5%), NT (находящиеся в состоянии, близком к угрожаемому) – 7 (8,0%), LC (вызывающие наименьшие опасения) – 32 (36,4%), DD (требующие дополнительных исследований) – 2 (2,3%); 43 вида охраняется в соответствии с Красной книгой Вьетнама (2007), в том числе EN – 11 (12,5%), VU – 32 (36,4%); 18 видов – в соответствии с Постановлением об охране редких и ценных видов флоры и фауны Вьетнама (2006). 37 видов, входящих в список МСОП, не охраняются во Вьетнаме. Однако 10 видов из этого списка со статусом EN, VU, NT могут составить ресурсную базу для реинтродукции их на территории, где виды исчезли или находятся на стадии полного вымирания. The study of the diversity of protected flora in the Nam Dong Nature Reserve (North Vietnam) was carried out as part of the study of the territory's flora in 2015–2019. The study was carried out on 7 profiles, laid down from the lowest heights to the highest point of the studied territory, in such a way that it would cover the maximum possible number of habitats on the slopes of different exposures. Floristic studies have made it possible to clarify the composition of rare and protected plant species of the territory that have international or national conservation status. Such plants in the reserve include 88 species (6.71% of all local flora) belonging to 51 families (28.33% of 180 flora families). Protected species belong to 3 divisions of vascular plants: Polypodiophyta – 5 species (5.68%), Pinophyta – 10 (11.36%), Magnoliophyta – 73 (82.95%). Of these, 57 species are listed in the IUCN (IUCN), including EN (endangered) – 7 (7.95%), VU (vulnerable) – 11 (12.50%), NT (near-threatened) – 7 (7.95%), LC (least concern) – 32 (36.36%), DD (requiring additional research) – 2 (2.27%); 43 species are protected in accordance with the Red Book of Vietnam (2007), including EN – 11 (12.50%), VU – 32 (36.36%); 18 species – in accordance with the Decree on of the Government on management of endangered, precious and rare forest plants and animals (2006). 37 species included in the IUCN list are not protected in Vietnam. However, 10 species from this list with the status EN, VU, NT, can form a resource base for their reintroduction in the territory where the species have disappeared or are at the stage of complete extinction.
