Mangroves are intertidal ecosystems that particularly vulnerable to climate change. At the low tidal limits of their range, they face swamping by rising sea levels; at high limits, increasing stress from desiccation and salinity. Facilitation theory may help guide mangrove management restoration in these threats suggesting how when positive intra- interspecific effects occur: such predicted stressed environments as intertidal, but have yet be shown among mangroves. Here, we report results a...
1. This study reports above-ground biomass of 5 and 8 years old mangrove plantations in Kenya. Trees with stem diameter greater than 5.0 cm inside 100 m2 sample plots were harvested, then separated into stems (trunks), branches, leaves prop roots. 2. Mean was calculated at 20.25 t dry matter ha−1 for Rhizophora mucronata Lam., 11.7 Avicennia marina (Forsk.) Vierh., 6.7 Sonneratia alba Sm. 3.7 Ceriops tagal (Perr.) C. B. Robinson. In A. R. mucronata, (52.19%) prop-roots (30.28%),...
The structure and species composition of undisturbed natural forests serve as benchmarks for understanding forest carbon storage potential reduced emissions. Even though Kenya is seeking to stabilize cover, reverse degradation increase cover through mechanisms such REDD+, there relatively little information on inherent or its response disturbance. Comparative studies were undertaken in three remnant fragments indigenous Taita Hills, characterize the undisturbed, moderately heavily disturbed...
Mangrove forests are among the most threatened ecosystems on earth. Some of these traverse national boundaries complicating their management due to differences in governance structures between countries. To improve transboundary species regular monitoring is essential. Remotely sensed data were used estimate forest cover and analyze conditions mangroves proposed conservation area (TBCA) Kenya Tanzania. Image analysis was performed using unsupervised supervised classification methods. The an...
The 2015-2016 El Niño had large impacts globally. effects were not as great anticipated in Kenya, however, leading some commentators to call it a 'non-event'. Our study uses novel combination of participatory Climate Vulnerability and Capacity Analysis tools, new existing social biophysical data, analyse vulnerability to, the multidimensional of, episode southern coastal Kenya. Using social-ecological systems lens unique dataset, our reveals overlooked by conventional analysis. We show how...

East African Afromontane Forests are among the carbon-rich ecosystems but their stability is mainly compromised due to seasonal wildfires. The objectives of study were (1) determine impacts wildfires on various carbon pools and (2) evaluate stock redistributions biomass components after within Aberdare Forest ranges, was conducted in nine sites that experienced 2022 two months fire occurrence. A total 35 concentric plots 15m radius distributed high severity (12), low (9) unburnt areas (14)...
Abstract The value of ecosystems functions performed by forests in the climate change era has prompted increasing attention towards assessment carbon stocks and fluxes tropical forests. aim this study was to understand how forest management approaches environmental controls impacted on soil CO 2 efflux a Eastern Mau which is one blocks greater complex Kenya. Nested experimental design approach employed where 32 plots were nested into four (disturbed natural, undisturbed plantation glades)....
The woody vegetation in semi-arid area is important providing ecosystem services and goods. However, it faces threats manifested land-use changes such as mining. This study aimed at assessing the composition diversity of well inherent soil physico-chemical parameters a previously mined comparing with semi-pristine adjacent area. Six transects containing five plots each were established within two blocks separated by river. In plot, data was collected on tree growth characteristics...
Abstract The management measures used for sustainable utilization of Clarias gariepinus in Lake Baringo do not have a stock assessment reference, attributable mainly to lack information on biological limits and target reference points. Assessment was carried out between August 2013 July 2014. A total 2772 fish were sampled from 25 boats (40%) 5 days each week length weight measurements. Fish Stock Tools yield model estimate population parameters, exploitation rate optimal fishing scenarios....
Afrixalus sylvaticus Schiøtz, 1974 is a species of hyperoliid frog inhabiting coastal forest Kenya. It classified as endangered under IUCN B2ab(iii) ver 3.1 and occurs in the Shimba Hills National Park hinterlands. Habitat loss other human activities are threatening species. Therefore, understanding breeding ecology population dynamics important for its conservation. This study assessed protected community landscapes Reserve Data was collected through ecological surveys conducted from June...
Water pollution from rivers and lakes has resulted in serious environmental issues on a global scale. The public's growing concern over the decline river lake water quality makes it more important than ever to assess of these bodies prolonged period time. During rainy dry seasons 2022, 120 samples were collected 5 monitoring stations located within River Njoro Lake Nakuru. underwent physicochemical analysis selected parameters, which included salinity, temperature, pH, turbidity, total...
