The inadequacy of information impedes society’s competence to find out the cause or degree of a problem or even to avoid further losses in an ecosystem. It becomes even harder to identify all the biological resources at risk because there is no exhaustive inventory of either fauna or flora of a particular region. Coastal forests of Kenya are located in the southeast part of Kenya and are distributed mainly in four counties: Kwale, Kilifi, Lamu, and Tana River County. They are a stretch of fragmented forests ca. 30−120 km away from the Indian Ocean, and they have existed for millions of years. Diversity of both fauna and flora is very high in these relicts and the coastal forests of Eastern Africa, extending along the coast from Somalia through Kenya and Tanzania to Mozambique, are ranked among the priority biodiversity hotspot in the world. In spite of the high plant species richness and their importance towards supporting the livelihoods of the communities that live around them, floristic studies in these forests have remained poorly investigated. Hence, based on numerous field investigations, plant lists from published monograph/literature, and data from BRAHMS (Botanical Records and Herbarium Management System) database at East African herbarium (EA), we present a detailed checklist of vascular plants recorded in this region. Our results show that Kenyan coastal forests play an essential role in the flora of Kenya and the plant diversity of the coastal forests of East Africa. The checklist represents 176 families, 981 genera, 2489 species, 100 infraspecific taxa, 90 endemic plants species, 72 exotic species, and 120 species that are included in the current IUCN Red List of Threatened Species as species of major concern. We also discovered three new species to the world from these relicts. Thus, Kenyan coastal forests present a remarkable and significant center of plant diversity.
Biodiversity, checklist, coastal forests, endemic, threatened species
Africa is among the world’s major centers of endemism and species-rich biodiversity regions (
Coastal forests of Eastern Africa are ranked among the 35 identified world’s biodiversity hotspots due to the concentration of many endemic species and habitat loss (
Loss of habitat due to human activities is the most severe threat to biodiversity and has become a major global environmental problem (
Floristic studies, however, provide a basic outline for plant conservation. Based on these studies, it is possible to determine the condition of an ecosystem, the primary relationships of species with each other or with the environment, and the identity of rare species or widespread species (
The study was carried out in the Kenyan coastal region located in the southeast part of Kenya (Fig.
Plant species data for the checklist of Kenya coastal forests were obtained from three primary sources. Firstly, collection records collected during floristic surveys carried out between 2015 and 2018. Different forest patches were visited and surveyed at different seasons to mainly cover the area where there had been few or no previous collections. The investigations included random walks while collecting fertile plant specimens. Details of collected specimens were recorded in a notebook. Information such as habit, habitat, location, and collector details were recorded as well. All collected materials were then processed (pressed and dried) and later deposited at the East Africa herbarium (
Further information about the species recorded at the coastal forests was checked on specimens found in the Global Biodiversity Information Facility (GBIF) (www.gbif.org). Identification of collected specimens was made using taxonomic monographs/floras (FT
A total of 2489 vascular plant species and 100 infraspecific taxa (subspecies and varieties) belonging to 981 genera and 176 families are comprehensively listed and presented here. This represents 39.55%, 63.78%, and 78.67%, respectively, of the total number of taxa found in Kenya flora (FT
The top 5 most species-rich families for coastal forests of Kenya are Fabaceae (226 species), Poaceae (207 species), Rubiaceae (137 species), Malvaceae (117 species), and Cyperaceae (111 species). The top 5 most species-rich genera are Cyperus (48 species, Cyperaceae), Euphorbia (28 species, Euphorbiaceae), Justicia (27 species, Acanthaceae), Ipomoea (25 species, Convolvulaceae), and Crotalaria (23 species, Fabaceae) (Table

Kenya coastal forests host a large number of species and provide a unique habitat for many species of special concern and endemic plant species. It harbors hundreds of plant species that are only found in coastal forests of East Africa. In addition, they are home to almost half of plant species found in Kenya flora (39.55%), and more than half of species found in the coastal forests of East Africa (65%). Despite this high plant diversity relevance, they have undergone a history of anthropogenic disturbance since the colonial era (
This checklist is designed for use by anybody interested in the plants of the Kenya coastal region. However, it will be most useful to professionals and students who have some botanical knowledge. Information such as voucher number, habit, habitat, altitude is recorded for each species. Species without voucher numbers were not included in the checklist. Species preceded by “?” means that there is doubt over the correct identification, those preceded with “letter” means that they have not been described and finally vouchers documented as “sr” means that they were sight recorded.
