National Bat Monitoring Programme


Funding Partners

BCT (host data), JNCC, NRW, DEFRA


Summary of Scheme
The National Bat Monitoring Programme (NBMP) is the only scheme for monitoring the population changes for the UK’s resident bat species. Established in 1996, volunteers collect data on distribution and abundance of bats in the UK from 2500 sites, producing population trend data.  The NBMP report provides trends since 1997 for 11 of the UK’s 17 resident bat species.
Bat species make up a third of the UK’s mammal fauna, occurring in most lowland habitats across the UK, and many of these are widespread throughout a variety of landscapes. Key pressures on bats (landscape change, agricultural intensification, development, habitat fragmentation) are also relevant to many other wildlife groups. Bats are sensitive to pollution and factors affecting their insect prey (e.g. pesticides, drainage, land management change). Climatic shifts are predicted to affect bat populations through changes in their yearly hibernation cycles, breeding success and food availability.

All bats and their roosts are protected by domestic and European legislation. The UK is a signatory to the EUROBATs agreement, set up under the Convention on Migratory Species. Information on bat trends is required for UK obligations under the EC Habitats Directive; seven of the UK’s bat species are also BAP priority species.

Mammal Data from Breeding Bird Survey


Funding Partners

BTO (host data), JNCC


Summary of Scheme:
Mammal monitoring has been part of the BBS since 1995, with the aim to help understanding of the population trends of common mammals. 75% of BBS observers now actively look for mammals or signs of mammals during their surveys. In 2013, 56 mammal species were recorded for which trends could be produced for nine.
In 2011, JNCC funded a comparison of BBS trends with results from the National Gamebag Census. Of the nine species compared, none differed significantly in the trends demonstrated between the two schemes.

National Gamebag Census


Partners

GWCT (funds scheme and hosts data), JNCC (provides periodic analysis of data)

 

Summary of Scheme
The National Gamebag Census (NGC) records abundance and distribution trends for 19 UK mammal species (excluding bats).  The NGC has been run by the Game and Wildlife Conservation Trust (GWCT) since 1961 and collates gamebag numbers of quarry species and predator species reported from 600 estates across the UK.  Analysis by the GWCT, commissioned by JNCC, has shown that mammal trends produced by the NGC are representative of mammal population trends in the wider countryside.
The NGC is valuable as it provides relatively long-term trends (most from 1961) for many predatory and game species, and has good coverage in remote areas such as the Highlands. Additional data from before 1961, supplied by estates with long- term records of their own, has been integrated with the more recent data, extending the time series back to 1900 for many species.
NGC data provides important background information on the distribution and changes in populations of some mammals, including four UK priority species, two of which are partially protected under the EC Habitats Directive.  The scheme also records several invasive non-native species that are impacting on native wildlife, including Muntjac and American mink.
