“…Kenya, and Nyambene Hills) Kenya, and the latter comprises the coastal forests of Kenya (Arabuko-Sokoke Forest and Shimba Hills) (Malonza et al, 2018). There are about 100 species of amphibians in Kenya (Malonza & Bwong, 2023), Nandi Forests being one of the components, support high species endemism and richness, at the same time face considerable threats relative to the remaining area (Mittermeier et al, 2005;Myers, 2003;Myers et al, 2000).…”

“…In some Kenyan localities, other taxonomic groups have attracted attention, for example invertebrates (Clausnitzer, 2003;Lehmann & Kioko, 2005), mammals (McDonald & Hamilton, 2010) and plants (Achieng et al, 2014;Luke, 2005) but other groups have been underexplored, for example, herpetofauna (Malonza & Bwong, 2023). Although, there has been past studies aimed at understanding the diversity, richness and distribution of amphibians in Key Biodiversity areas (KBA), and particularly diverse in forest areas of Kenya (Bwong et al, 2009Lötters et al, 2007;Malonza et al, 2010Malonza et al, , 2018Malonza & Veith, 2012;Ng'endo et al, 2011;Wagner et al, 2008) but there is still a significant gap in our knowledge regarding some parts of western Kenya's anuran biodiversity patterns, that includes largely underexplored North Nandi Forest Reserve (Malonza, 2011) and Kingwal Swamp.…”

Anuran species are some of the good environmental indicators of habitat quality and condition in ecosystems. This is due to their amphibious life modes and sensitivity to environmental change caused by rapid expansion of agricultural activities, advancement of forest destruction, climate change and emerging infectious diseases. Understanding their diversity and distribution patterns is crucial for the development and implementation of effective species and habitat conservation strategies. The study aimed at assessing and comparing anuran biodiversity and distribution patterns between a protected (North Nandi Forest Reserve) and a non‐protected area (Kingwal swamp) to provide additional baseline information, both being among the underexplored areas in Kenya. Data were gathered in both dry and wet seasons, between October 2022 and June 2023 by employing standard sampling techniques for anurans(Visual encounter and pitfall traps with a drift fence) to maximise detection. Three habitat types‐ farmland, intermediate land and forest were exploited. A total of 1649 individuals from 21 different species, belonging to nine different genera and nine different families were recorded. Ptychadenidae was the most abundant family from the recorded anurans, while Dicroglossidae, Arthroleptidae, Pyxicephalidae and Ranidae were the least. High biodiversity was observed in the forest habitat (Protected) and least in the farmland (non‐protected). The wet season had high species abundance, diversity and richness compared to the dry season. There was a significant difference (p < 0.05) in diversity between the habitats in wet season, but no significance difference during dry season (p > 0.05) except for forest and farmland (p < 0.05). There was a significant difference in species abundance between seasons (p < 0.05), and between habitats (p < 0.05) in all seasons except for farmland and intermediate (p > 0.05), as well as farmland and forest (p > 0.05) during the wet season. Habitat type and season had no influence (p > 0.05) on species richness. Anuran biodiversity is a function of habitat diversity and season, with the associated differences in microhabitat structure providing diverse niches and ways of exploring resources. The modest sampling indicates that Kingwal Swamp and North Nandi Forest Reserve are rich and support anuran species, and the differences in anuran biodiversity between the 3 habitats demonstrates that conservation efforts continue to be a priority.

Interpretation and implementation of the ConventionCompliance and enforcement Review of Significant Trade in specimens of Appendix-II species [Resolution Conf. 12.8 (Rev. CoP13)] SPECIES SELECTED FOLLOWING COP151. This document has been prepared by the Secretariat. 3. At its 26th meeting (AC26, Geneva, 2012), the Committee reviewed the available information on these taxa in accordance with paragraph f) of Resolution Conf. 12.8 (Rev. CoP13). In instances where the Committee was satisfied that Article IV, paragraph 2 (a), 3 or 6 (a), was correctly implemented, it eliminated the species from the review with respect to the range State concerned, and these range States were notified accordingly by the Secretariat (see document AC26 Doc.12.3 and the summary record of AC26). At its 25th meeting (AC25,Geneva4. At AC26, the Committee also agreed that prior to the compilation of information called for in paragraph g), range States that had been kept in the process due to a lack of response but where no commercial trade had been recorded over the most recent 10 years, would be removed from the process in consultation with the Animals Committee. The taxa and range States that were thus retained in the review are shown in the table below. Taxa selected following CoP15 and retained in the review after AC26 Taxon selected Range StateMacaca fascicularis Cambodia; India, Indonesia, Lao People's Democratic Republic, Mauritius, Palau, Philippines, Viet Nam Psittacus erithacusBenin, Central African Republic, Ghana, Nigeria, Togo, Uganda Chamaeleo gracilisBenin, Cameroon, Ghana, Guinea, Togo, Uganda Chamaeleo senegalensisBenin, Ghana, Guinea, Mali, Senegal, Sierra Leone Trioceros melleri Mozambique Trioceros quadricornisCameroon, Nigeria Trachyphyllia geoffroyi Singapore, Solomon Islands 5. In accordance with paragraph g) of the Resolution, the Secretariat proceeded with the compilation of information regarding the species mentioned in the table above. The UNEP World Conservation Monitoring Centre (UNEP-WCMC) was engaged to compile information about the biology and management of and trade in these species, and to provide a preliminary categorization of the species in compliance with paragraphs h) and i). The Secretariat transmitted the resulting reports from UNEP-WCMC to relevant range States on 13 and 19 December 2013, which had 60 days to submit comments in accordance with paragraph j). Kinyongia fischeri United Republic of Tanzania Kinyongia tavetana United Republic of Tanzania Ptyas mucosus6. The species reports of UNEP-WCMC present conclusions about the effects of international trade on the selected species, the basis on which such conclusions are made, and problems with the implementation of Article IV of the Convention. They provide preliminary categorizations of each species into one of the three categories outlined in paragraph i) of Resolution Conf. 12.8 (Rev. CoP13), namely: i) 'species of urgent concern' shall include species for which the available information indicates that the provisions of Article IV, paragraph 2 ...

Amphibians are sensitive to changes in the environment and are, therefore, excellent indicators of success in restoring degraded habitats. As such, a clear understanding on how amphibian populations respond to changes in the environment is required. In order for conservationists to establish if the declining trends are changing, biodiversity recovery studies are essential especially in reclaimed habitats. This study focused on the recovery of amphibians, particularly on frogs, in reclaimed quarries of the Bamburi Cement Plant near Mombasa whereby the diversity, species abundances and composition at different stages of quarry re-establishment were assessed. The study area was divided into three zones based on the 13-year interval since the beginning of the rehabilitation process. Transect surveys and time-constrained search and size method were used for sampling 20 randomly selected sites. Sampling was done during the rainy and the dry seasons, with searches conducted between 900 and 1,600 hours during the day and between 1,800 to 2,100 hours at night. Recording of basic morphological data of collected specimens was done in the field to aid in grouping specimens before voucher materials were preserved in 10% formalin and stored in 70% alcohol. Further identifications and confirmations matching specimens to species were carried out using specialized classification keys from the National Museum of Kenya. Twelve species were encountered across the three zones, with Ptychadena anchietae and Phrynobatrachus acridoides, respectively, the most abundant. It was also noted that amphibian diversity across the quarries was independent of the age of ecological reestablishment (r = -0.5). This is indicated by the higher amphibian diversity in the south and north quarries (N = 1050 and 506 respectively) despite their relatively younger age since reestablishment compared to the central quarry (N = 438). Lower diversity in the central quarry, although the oldest, may be largely attributed to human disturbance. Additionally, exotic plantations across the study area are poor in species since they are monocultures and, thus, not heterogeneous enough to support higher anuran diversity. Since amphibians act as one of the best measure of environmental health, rehabilitation process in the quarries need to embrace mechanisms that support maximum biodiversity recovery such as replanting of more indigenous tree species as opposed to only exotic monocultures.
