description Background. Montane forests encompass spectacular landscapes, a wide variety of ecosystems, a great diversity of species, and distinctive human communities. Mountain forests support about one quarter of world’s terrestrial biodiversity and include nearly half of the world’s biodiversity “hotspots. Understanding of land  use  change (LUC) in mountain forest ecosystem  is  crucial  for  sustainable  management of the ecosystem especially in developing countries like Kenya where the majority of the people depend  on natural  resources  for  their  livelihoods. Changes in land use in this forest ecosystem could lead to a decline in biodiversity and in the livelihoods of the forest adjacent communities. Objective: To evaluate the differences in land use changes and floral diversity of Mt. Elgon forest ecosystem. Methodology: Differences in land use changes on floral diversity were evaluated using quadrats that were placed in different land uses to measure species diversity and abundance. The Shannon-Weiner diversity index and Whittaker beta diversity index was used to determine changes and similarities in floral diversity, while Kruskal-Wallis test and chi square test was used to determine differences in species abundances. Result: This study established that there were differences in floral diversity in relations to land use changes. The Shannon-Weiner diversity index revealed that control (natural forest) site had the highest species diversity (H=2.07331, evenness=0.884), followed by indigenous plantations (H=1.93962; evenness 0.69957), urban settlements (H=1.85081; evenness=0.66754), Nyayo Tea Zone (H=1.5324, evenness=0.56), mixed farming (H=1.43694, evenness=0.43694) and exotic plantation (H=1.28231, evenness=0.61612). Whittaker beta diversity index for control site verses urban settlements was (0.5385), indigenous plantations (0.2222), Nyayo Tea Zone (0.1429) while mixed farming and exotic plantations (0.000). Kruskal-Wallis test revealed a statistically significant differences in total number of plant species in the various study sites (H=8.288; P=0.049). Similarly, the results revealed a significant difference between specific plant communities (trees, shrubs, herbs, ferns, and climbers) in the study area (H=38.116; P=0.000). Chi square test of homogeneity was used to test difference in distribution of species communities in different location and the results revealed that the differences were insignificant. Implications: Results of species diversity analyses show differences in floral diversity and similarities in areas under different land uses. Conclusion: There are significant differences in floral diversity in areas under different land uses of Mt. Elgon forest ecosystem. Species diversity and similarity of indigenous planted forests and urban settlement closely approach that of the natural forests. Floral diversity play a critical role in provisioning of essential ecosystem services.

Los bosques montanos abarcan paisajes espectaculares, una amplia variedad de ecosistemas, una gran diversidad de especies y comunidades humanas distintivas. Los bosques de montaña apoyan aproximadamente una cuarta parte de la biodiversidad terrestre del mundo e incluyen casi la mitad de los "puntos críticos" de la biodiversidad mundial. La comprensión del cambio de uso de la tierra (LUC) en los ecosistemas forestales de montaña es crucial para la gestión sostenible del ecosistema, especialmente en países en desarrollo como Kenia, donde la mayoría de las personas dependen de los recursos naturales para sus medios de vida. Los cambios en el uso de la tierra en este ecosistema forestal podrían conducir a una disminución de la biodiversidad y de los medios de vida de las comunidades adyacentes a los bosques. Objetivo: Evaluar las diferencias en los cambios en el uso de la tierra y la diversidad floral del ecosistema forestal del Monte Elgon. Metodología: Las diferencias en los cambios en el uso de la tierra en la diversidad floral se evaluaron utilizando cuadriláteros que se colocaron en diferentes usos de la tierra para medir la diversidad y abundancia de especies. El índice de diversidad Shannon-Weiner y el índice de diversidad beta de Whittaker se utilizaron para determinar los cambios y similitudes en la diversidad floral, mientras que la prueba Kruskal-Wallis y la prueba de chi cuadrado se utilizaron para determinar las diferencias en las abundancias de especies. Resultado: Este estudio esTableció que había diferencias en la diversidad floral en las relaciones con los cambios en el uso de la tierra. El índice de diversidad Shannon-Weiner reveló que el sitio de control (bosque natural) tenía la mayor diversidad de especies (H=2.07331, evenness=0.884), seguido de las plantaciones indígenas (H=1.93962; evenness 0.69957), asentamientos urbanos (H=1.85081; evenness=0.66754), Nyayo Tea Zone (H=1.5324, evenness=0.56), agricultura mixta (H=1.43694, evenness=0.43694) y plantación exótica (H=1.28231, evenness=0.61612). El índice de diversidad beta de Whittaker para los asentamientos urbanos de versos de sitio de control fue (0,5385), las plantaciones indígenas (0,2222), la Zona del Té de Nyayo (0,1429) mientras que la agricultura mixta y las plantaciones exóticas (0,000). La prueba Kruskal-Wallis reveló diferencias estadísticamente significativas en el número total de especies vegetales en los diversos sitios de estudio (H=8.288; P=0,049). Del mismo modo, los resultados revelaron una diferencia significativa entre comunidades vegetales específicas (árboles, arbustos, hierbas, helechos y escaladores) en el área de estudio (H=38.116; P=0,000). La prueba de homogeneidad de chi cuadrado se utilizó para probar la diferencia en la distribución de las comunidades de especies en diferentes lugares y los resultados revelaron que las diferencias eran insignificantes. Implicaciones: Los resultados de los análisis de diversidad de especies muestran diferencias en la diversidad floral y similitudes en áreas bajo diferentes usos de la tierra. Conclusión:  Hay diferencias significativas en la diversidad floral en áreas bajo diferentes usos de la tierra del ecosistema forestal del Monte Elgon. La diversidad de especies y la similitud de los bosques plantados autóctonos y los asentamientos urbanos se acercan estrechamente a la de los bosques naturales. La diversidad floral desempeña un papel fundamental en el suministro de servicios esenciales de los ecosistemas.Universidad Autónoma de YucatanMoi University, Kenya Forest Service2021-08-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://www.revista.ccba.uady.mx/ojs/index.php/TSA/article/view/3452urn:ISSN:1870-0462-tsaes.v24i3.3452810.56369/tsaes.3452Tropical and Subtropical Agroecosystems; Vol 24, No 3 (2021): (September - December)Tropical and Subtropical Agroecosystems; Vol 24, No 3 (2021): (September - December)1870-0462reponame:Tropical and Subtropical Agroecosystemsinstname:UNIVERSIDAD AUTÓNOMA DE YUCATÁNinstacron:UADYenghttps://www.revista.ccba.uady.mx/ojs/index.php/TSA/article/view/3452/1655Copyright (c) 2021 Nelly Nambande Masayi, Tsingalia Mungatsia, Paul Omondihttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessoai:ojs.www.revista.ccba.uady.mx:article/34522024-08-22T17:22:57Z
