1 Provisional Atlas of Nottinghamshire Mammals September 21

2 Diversity 1-2 (11) - (2) - (1) - () - 1 () (1) 1-1 (11) 1-1 () 1-22 () All mammal records excluding bats Mammal Recording in Nottinghamshire Nottinghamshire's mammal species are very under-recorded and their distributions in the county are therefore poorly known. The purpose of this atlas is to encourage recording and to help us to identify the species that are at highest risk and the areas that are particularly important for mammals. Some species are of particular conservation concern, e.g. Water Vole and Harvest Mouse, and are known to be declining. For other species, such as water shrew, we just don't have enough data to know their status in the county. Your records are extremely important and will help to give us a much clearer picture of Nottinghamshire s mammal distribution and will enable the production a full atlas of all our species in the next few years. The information will help us to target conservation action to conserve our species and, hopefully, to bring our most vulnerable species back from the brink. The data will also help to identify areas which are suitable for designation as Local Wildlife Sites for their importance to mammals. Information on how to submit your records can be found after the maps section. The following maps show the current situation of mammal recording in Nottinghamshire. A project of this kind can only be completed with the help of volunteers so thank you to everyone who has submitted records over the last few years. The county mammal database has also been greatly enhanced by additional datasets provided by the Nottinghamshire Biological and Geological Records Centre, Sorby Natural History Society and the BTO Garden BirdWatch and Breeding Bird Surveys. The Nottinghamshire Bat Group are currently working on bat distribution in the county and maps may be included in future updates of this atlas. Nottinghamshire covers an area of 21km 2 but there are 2 1km squares that have a part of the county within them. To date 12, or %, of these square have recorded at least one mammal species (see map left). Species are mapped at 1km square level with the exception of badger which is shown at 2km square level to reflect the illegal persecution that this species still suffers from. Otter is not included in this edition but they are increasing their range in the county. Records of seals, dolphin and porpoise which are occasionally recorded in the tidal section of the River Trent north of Cromwell are also excluded as they are not resident populations. Please contact me if you have any questions about the atlas project or have ideas on how we could improve the recording of mammals in Nottinghamshire Michael Walker, Nottinghamshire Mammal Recorder mwalker@nottswt.co.uk

12 How to submit mammal records There are several ways to send in your mammal records. By Records can be sent to Records should include the following details : Species Your name The date OS grid reference (at least to 1km square level but preferably to 1m) Location name How identified (was it dead on a road, alive, a field sign e.g. mole hills, footprints, droppings etc) How many did you see Any other notes you want to add (e.g. habitat, age, sex). If you have a large number of records it would be helpful if they could be collated into a spreadsheet (Excel or CSV file). An Excel template is available on request. Using Mammal Tracker The Mammal Tracker app is available for iphone or Android and make mammal recording extremely easy. It uses the GPS in the phone to accurately record the location and there is identification help within the app. All records submitted are verified locally and will be included in the county dataset. If you don't have a smart phone you can still use the Mammal Tracker website to send in your records. There is a very easy interface which is quick to use and is quick to find the location grid reference. By post If you don't have access to or the internet, records can be sent by post to: Michael Walker, Nottinghamshire Wildlife Trust, The Old Ragged School, Brook Street, Nottingham, NG1 1EA Photographs Some mammal species can be difficult to identify. If you are unsure of a species you see I am always happy to receive photographs. Whilst taking pictures of live animals is difficult photographs can be very useful to identify animals that have been found dead. Records of polecat are particularly welcome if there is a picture to help verify the identification. The Mammal Tracker app has a feature which enables pictures to be added to the submitted record. Your records will be added to the Nottinghamshire Mammal Database and shared with the Nottinghamshire Biological and Geological Records Centre and be included in the Mammal Society Atlas project.
