While many would imagine that mammals are extensively recorded there are actually limited records, compared to other groups. While Blaythwayt (1912) published a 'Preliminary List of the Lincolnshire Mammals' it was not until 1982 that the first 'Atlas of the Mammals, Reptiles and Amphibians of Lincolnshire and South Humberside' was produced by Johnson. Much later again a brief update on mammal recording was published by Manning in 2010.
National mammal survey and species accounts are relatively well known and frequent. In Lincolnshire they are notable by their scarcity - a survey of grey and red squirrels was carried out by the War Agricultural Executive Committee (Shorten, 1946); with a review of the mustelids of Lincolnshire (Crick, 2004) and deer and deer parks (Manning, 2006) in more recent years. Recording of individual species is now more regularly undertaken at an organisational level and fed into wider schemes; for example the water vole monitoring undertaken by many of the Internal Drainage Boards.
