Insect pollinator numbers are affected by many different environmental and socio-economic factors but attributing long term change in pollinator numbers to one or more of these is difficult. Scientists are beginning to understand how these different factors interact with each other, and which ardmore important for particular insect groups, but there is no single, simple explanation for pollinator decline.
