The Kalábová (K1) and Kalábová 2 (K2) Nature Monuments are located in the central part of the White Carpathians PLA near the village of Březová. Both monuments protect treeless wet grasslands and tufa forming spring fens, which were originally part of a larger wetland complex. A total of 51 species were recorded in K1 (47 terrestrial and two aquatic gastropods and two bivalves). Of these, 30 species (56%) are woodland dwellers that were recorded during the survey in 2000, shortly after the area was logged. In contrast, none of these species was detected during the recent survey in 2021. However, these species are widespread in the region and Nature Monuments surroundings and some are likely present also in the ecotones of the spring meadow and adjacent forest. Currently, hygrophilous and wetland dwellers dominate (9 spp.; 17%), followed by ubiquitous (7; 15%), open-ground (4; 8%) and aquatic species (4; 8%). At K2, 19 species were recorded, including 15 terrestrial and two aquatic gastropods, and two bivalves. The two most species-rich ecogroups were hygrophilous and wetland dwellers (5; 26%) and woodland dwellers (5; 26%), the latter were prevailing probably due to relatively recent deforestation between 2012–2014. Aquatic species were represented by four species (21%), followed by three ubiquitous (16%) and one open-ground (5%) species. The spring dweller Bythinella austriaca (NT) and the declining wetland umbrella species Vertigo angustior (VU; NATURA 2000) inhabited both localities in high densities. To maintain the favourable habitat conservation status of the reserves, the sites should be managed extensively by grazing or mowing.

Identifying how policy, socioeconomic factors, and environmental factors influence changes in human well-being (HWB) and conservation efficiency is important for ecological management and sustainable development, especially in the Giant Panda National Park (GPNP). In this study, we systematically analyzed the differences in the conservation status of the giant panda habitat and changes in HWB over 15 years in the GPNP, which includes six mountain sites, Minshan (MS), Qionglai (QLS), Xiaoxiangling (XXL), Liangshan (LS), Qinling (QL), and Daxiangling (DXL). Redundancy analyses were used to determine the factors contributing (policy, socioeconomic factors, and environmental factors) to HWB and giant panda habitat conservation (HC). In addition, using a structural equation model (SEM), we investigated the relationship between the aforementioned three factors and their direct and indirect effects on HWB and HC. The results indicated that there was spatiotemporal heterogeneity of HWB and HC in our study area. There was an increasing number of plant species as well as an increased number of giant panda in GPNP. Generally, HWB in 2015 showed an increasing trend compared with that in 2000. Socioeconomic factors (23.6%) have the biggest influence on HWB and HC, followed by policy (23.2%) and environmental factors (19.4%). Conservation policy had a significantly positive influence on HWB (0.52), while it negatively influenced HC (−0.15). Socioeconomic factors significantly negatively influenced HWB (−0.38). The formulation and implementation of policies to promote economic development will contribute to the protection of giant pandas and their habitat. Our results provide insight on the conservation status of the giant panda habitat, HWB, and factors influencing them in different mountain sites in the GPNP, as well as having implications for the future management of the GPNP.

Opuntia soederstromiana is recorded in Colombia for the first time. Botanical explorations were carried out in eastern Colombia sub-xerophytic enclaves, as well as examination of specimens deposited at the herbaria AZUAY, COL, GH, NY, QCA, QCNE, UPTC, and US was made. Lectotypes for the names O. dobbieana (here treated as heterotypic synonym of O. soederstromiana) and O. soederstromiana are designated on specimens preserved at US and NY. A detailed and expanded morphological description of O. soederstromiana, as well as data about type, habitat, conservation status, selected iconographies, and distribution area were given. The number of Opuntia species recorded in Colombia has increased to 10. A key for identification of Opuntia species occurring in the departments of Boyacá and Santander (Colombia) was also provided.

A New Species

Recent botanical expeditions to the Dolphin Head Mountains in western Jamaica allowed the collection of different specimens of a new species, Hohenbergia rohan-estyi, an enigmatic plant that resembles the also Jamaican-endemic H. negrilensis. In this study, we describe H. rohan-estyi and include notes on its geographical distribution, habitat, conservation status and taxonomy. The length of the stipes and number of flowers per spike permit the differentiation of H. rohan-estyi from H. negrilensis. In addition, the geographic distributions of these two species do not overlap, as H. rohan-estyi inhabits mountainous forests of the Dolphin Head region while H. negrilensis occurs in coastal areas of western Jamaica. Finally, H. rohan-estyi is the third species of Hohenbergia reported as endemic to the Dolphin Head Mountains, indicating the importance of this area in the evolution and conservation of the genus in Jamaica and the Caribbean.

Summary Routine use of the virtual herbarium of the collections in COL (Instituto de Ciencias Naturales de la Universidad Nacional de Colombia) revealed the presence of an as yet undescribed species of Senecio amongst the material of Senecio adglacialis and S. leucanthemoides. Following subsequent herbarium studies and fieldwork, Senecio scapioides (Compositae: Senecioneae: Senecioniinae), from the Departamento de Boyacá, in Andean Colombia, was recognised and is described and illustrated; it is compared with S. adglacialis and S. leucanthemoides. Notes on its distribution and habitat, conservation status, phenology, and etymology are also provided, and the distribution of the three species mapped.

All available data and most of materials on Acicula parcelineata from Ukraine are reviewed. Thirteen areas inhabited by the species are reported for Ukraine, some of which include several known sites. Five of these areas were not reported before. Map of general distribution of A. parcelineata is provided (outside Ukraine based on published data). Habitat preferences of this species are reviewed, it occurs in Ukraine almost exclusively in forests with presence of beech, on altitude 300-1100 m. Conservation status of A. parcelineata in Ukraine is shown to be “Near Threatened” according to IUCN criterions, it is recommended to be included into the next edition of Red Book of Ukraine. Shells’ measurements of A. parcelineata are provided and compared with related Platyla jankowskiana. The later species is discussed; it seems to be possible that it represents large abnormal specimens of A. parcelineata.

This paper describes the distribution, population size and conservation needs of the land snail Gulella taitensis (Gastropoda: Streptaxidae) endemic to the Taita Hills, Kenya. The species was investigated using timed searches between July and December 2000. In total 37 snails were recorded from only five of nine forest fragments searched. The snail was generally more abundant in the smaller forest fragments. The species appears to be a forest specialist, exhibiting preference for the least disturbed sections of forest. The small population size, restricted distribution and concentration in the smallest and most fragile forest fragments suggests the species is on the brink of extinction. The species fulfills the requirements for changing its conservation status from Endangered to Critically Endangered on the IUCN Red List. Promotion of the Forest Reserves to a conservation category that provides greater legal protection is necessary.
