STATUS OF POLLINATOR STUDIES IN KENYA Mary Gikungu
Background information • Pollinator studies in Kenya are at their infancy • Only a few studies have been published (e.g. Bogdan 1962, Onim, 1979, Morimoto et al, 2004, Njoroge et al, 2004, Gikungu 2002,Gikungu, 2007). • The first pollinator study in Kenya was conducted by Bogdan (1962) on grass pollination but this was followed by a lag phase in pollinator research (Fig. 1). • The current pollinator studies in Kenya endeavor to adhere to the key priority topics as identified by Food and Agriculture Organization of the United Nations (FAO) and International Pollinators Initiative (IPI). These include, • Monitor pollinator decline, its causes and its impact on pollination services • Address the lack of taxonomic information and expertise on pollinators • Assess the economic value of pollination and the economic impact of the decline of pollination services. • Promote the conservation and the restoration and sustainable use of pollinator diversity in agriculture and related ecosystems.

Threats • Deforestation • Habitat fragmentation • Fires-slash and burn agriculture • Use of agrochemicals • Charcoal production • Pests and diseases • Poor honey harvesting methods • Climate change
Why bees?? • Pollinate 75 % of world’s flowering plants • Facilitate regeneration of vegetation cover • Indicators of habitat quality • Income generation-beekeeping & pollination service, BUT • Decline observed • Scarcity of data

Annual net economic benefit derived from bee pollination (on eight different crops) in the Kakamega region is approximately to 3.19 M US$.
Identification of pollinator species • Has been a great challenge • Reliance on Keys from South Africa and other counties • Insufficient taxonomic expertise • Small collections with insufficient observation data • Huge gaps in pollination ecology at all levels
Digitization of collection and observation data • The National Museums has been digitizing all the in invertebrate collections • This work has been supported by the federal government of Germany through BIOTA East (Biodiversity Monitoring Transect Analysis in Africa Project) • A database on plant/pollinator interactions is underway
Promotion of Pollinator conservation in Kenya • Capacity building (two taxonomic and pollination ecology courses held through BIOTA, EAFRINET, SAFRINET and York University), next one in August at NMK for one month • Pollination ecology and Bee taxonomy centre at NMK • Community parataxonomist courses • Promotion of Meliponiculture and Apiculture • Establishment of pollinator gardens • Increased collaborations • GEF pollinator project • Mainstreaming of pollinator conservation
Challenges • Ignorance on pollinator input in crop production by agricultural sector and environmental conservation programs. • Biology and ecological knowledge of pollinators • missing • Lack of standard sampling protocols in study design, sampling procedures, data analysis and reporting • Taxonomic impediment • Lack of local keys or guides • No comprehensive data on pollinator diversity • Lack of pollinator conservation policies • UNKNOWN estimates of pollinator decline
Way forward • Need for increased pollinator studies at landscape level, pollinator management and restoration in every part of the country. • Increased understanding of pollinator networks in different eco/regions • Increased research collaborations • Need for local guides, taxonomic keys, websites etc • Pollinator conservation policies
