Sussex Harvest Mouse Survey

The Sussex Harvest Mouse Survey aims to give us a greater understanding of this tiny mammal's distribution across Sussex.

The best way to identify whether harvest mice are using a site is to search for their characteristic nests, which are woven from shredded leaves of plants such as grasses, sedges and reed.

Harvest mouse numbers are at their highest in the autumn so the time couldn't be more right to get out searching suitable habitats such as long, tussocky vegetation, reedbeds, and grassy scrub!

Surveyors joining the Sussex Harvest Mouse Survey will be allocated a tetrad (2km x 2km square) to search for harvest mouse nests.

To turn your nest sighting in to a record you just need to make a note of:
  • where you saw it (location and grid reference)
  • when you saw it
  • who you are
  • then pop along to iRecord and wait for your record appear on the Sussex distribution map

But if you want to go that extra mile for harvest mice, you could also record: 
  • the width of the nest
  • its height above ground-level
  • the height of the vegetation in which the nest was located
  • the plant from which the nest had been woven.
