*Walthamstow Marshes: The 1970s Survey has records of Harvest Mice stripping phalaris reed grass for nesting material. (The survey also records ferret) See link: http://www.clubplan.org/CMS/usr/20169/Publications/WalthamstowMarshesSurvey_1970s.PDF

**A single stoat ran north, along left hedgerow of concrete path in between paddocks and bomb crater field, 8 April 2015

***Otter spraint found at Walthamstow Reservoirs by ecologist, Graham White after they were reintroduced to Amwell and this news article citing Otter spraint being found on Walthamstow Marshes: https://www.hackneycitizen.co.uk/2013/08/28/otters-lea-valley/

****Water Shrew recorded by Nathaniel Legall on the Bomb Crater Field of Walthamstow Marshes.

Badger has been claimed on Walthamstow (see below link). However, the Occupy badger 'sighting' is dubious to say the least and the ‘record’ dosen't make it onto the list.

Mammals which Walthamstow realistically could hold but have yet to be recorded:

Yellow Necked Mouse

The full 101 UK mammal species list can be found on The Mammal Society’s web page here: http://www.mammal.org.uk/species-hub/uk-mammal-list/
