The last island-wide survey, The Jersey Bat Survey, was carried out by Louise Magris of the States of Jersey Environment Department, dated October 2003. Now, in 2016 the Jersey Bat Group are expanding the Woodland project to include netting/harp trapping of bats to identify the baseline species that occur here.  We have already added two species to our inventory, Alcathoe and Daubenton’s,  and hope to discover more.

In 2013 the Bat group discovered a Serotine roost which consisted of one or more Serotine bats in St. Mary’s Church.  This species has been recorded many times since then in St Mary’s Village and at a private Waterworks station.  In 2015 it was recorded at a large property in St Ouen and several times in St Peter and St Mary.

Many hours were spent viewing and recording the emergence and return of a single Serotine bat on the south side of the church.  This bat was visible on several occasions just before dusk and due to size and colour was suspected to be a Serotine.  Ecolocation recording confirmed that the bat was most likely a Serotine and lastly, we were able to analyse it’s droppings for the final confirmation.

Also in 2013, whilst Orly Razgour, Phd graduate from Bristol university, was over in Jersey surveying for Grey Long-eared bats, she discovered a Greater Horseshoe call on one of her recordings.  The ecolocation call of this bat is very distinctive and is unlikely to be mixed up with any other bats.  More investigation is needed to discover whether this bat was a vagrant or is a resident.

A call resembling a Noctule was recorded in St Peter’s Valley in July 2014 so it is likely that this species exists here in the summer at least, probably as a vagrant from France.

In August 2015 a small bat was seen skimming the water over one of our small reservoirs.  We managed to take recordings which did indeed resemble those of a Daubenton’s. Finally we have confirmed this sighting by capturing a Daubenton’s Bat at Val de la Mare Reservoir in July 2016.
