“…These forests are surrounded by many people who depend on them entirely or partially for their ecosystem services like timber, firewood, pasture, charcoal, medicinal plants for people and livestock and building materials, amongst many other functions ( Fashing and Mwangi 2004 ; Akwee et al 2010 ; Maua et al 2018b ).…”

We compiled a checklist of the flora of South and North Nandi forests based on literature, online databases, herbarium collections and floristic field surveys. A combination of general walk-over surveys and plotless landscape sampling for plant collection and sight observation was used. We recorded 628 plant species representing 118 families and 392 genera, which almost double the latest results of the previous most recent survey. We found 61 species of ferns and fern allies and 567 species of seed plants, representing 9.98% of the total plant species in Kenya. Herbs were the majority (50.2%) of life forms followed by shrubs (16.5%). We report unique populations of three species out of 19 species that are widespread in Africa, but restricted to Nandi and Kakamega Forests in Kenya. Four of the recorded species are threatened globally and 16 exotic plant species were found. The recent description of one new species and two new records for Kenya from these forests, together with the comprehensive checklist is of crucial importance to the conservation of these unique ecosystems. Our results are essential to forest managers, community forest associations, conservationists, students and research scientists in Kenya and globally for implementing critical decisions for the conservation of this vital biodiversity resource.

The management of regeneration plays a vital role in sustainable forest practice by ensuring the future growing carbon stock and serving as an indicator of the forest condition of an area. In premises of the above-mentioned facts, the current study was conducted to investigate the population structure and regeneration status of woody species as an indicator for forest condition and to provide information on sustainable management of the woody plants in Chilimo-Gaji Forest. The data collection was done using a preferential sampling technique as a sampling design and a total of 36 plots with a size of 20 m × 20 m (400 m 2) was laid out for the woody species. In each sample plot, all woody species seedling, sapling and mature tree/shrubs were counted and recorded. And their diameter at breast height (DBH) was measured at 1.5 from the ground with DBH ≥ 2.5 cm. A total of 42 species of vascular plants belonging to 34 genera and 28 families were recorded and identified from the 36 study plots. The total density of woody plant species in all the 36 sampled plots of the study area was 3328.47 individuals ha-1. The total density of seedlings, saplings and trees/shrubs were 1743.75, 827.08 and 757.64 ha-1 , respectively. The regeneration status of individual tree species showed differences as 26% had good regeneration, 43% had fair regeneration, 7% had poor regeneration, 7% lacked regeneration, and 17% have appeared as newly regenerating. The cumulative species DBH class distribution of the study area was inverted J-shape distribution indicating stable population status or good regeneration status.

“…However, while the strategy of Arlomom project was to intervene in a buffer zone around the Patako Forest, another initiative called Nebeday recently consisted of reforestation and beekeeping activities within the forest to enhance biodiversity. The study site is biologically diverse in terms of floristic composition and could be an important provider of ecosystem services since diversity often is indicative of better ecosystem functioning (Akwee et al, 2010). The biodiversity information could be used by decision makers and conservation technicians to enhance its management and reinforce rare species in degraded areas of the Patako Forest.…”

Due to the presence of tree species of high socio-economic importance, many protected areas in the sudanian zone are facing anthropogenic pressure that threatens their stability and resources integrity. This study aimed at providing a better understanding of woody plant composition and structure in Patako Forest in Senegal. Data collection was conducted by stratified random sampling in a total of 251 plots in different vegetation types. The results indicated that Combretum glutinosum, Terminalia macroptera, Cordyla pinnata, Elaeis guineensis, Acacia macrostachya and Khaya senegalensis were the most representative species. The Importance Value Indices (IVI) of these species varied significantly among vegetation types. Species diversity and structural characteristics were higher in gallery forest. The most important Shannon diversity indices was recorded in gallery forest (2.81) while it was medium in both woodland (2.12), tree savanna (1.55) and shrub savanna (1.24). Tree density was dominated by multi-stemmed species. Stem density was significantly higher in gallery forest (536 ± 13 per ha) and woodland (526 ± 12 per ha) than in tree savanna (364 ± 15 per ha) and shrub savanna (309 ± 14 per ha). Forest management should focus on gallery forest to enhance biodiversity conservation and increase the potential of carbon sequestration.
