Widespread Amphibian & Reptile Surveys
The NARRS widespread amphibian and reptile surveys form the core of what most people think of as “NARRS”.
These are the first robust and repeatable ongoing surveys that will provide long-term information about our widespread herpetofauna. There is growing concern that widespread species (such as the adder and common toad) are undergoing serious declines.
NARRS PHASE 1
CONGRATULATIONS to everyone who’s been doing the NARRS
PHASE 1 (random square) surveys – we now have data from 10 years’ of
surveying! We’re going to be analysing all these data and looking for
trends in occupancy early in 2017, so please submit your 2016 results as
soon as you can! In order to work out what’s next for NARRS 1, we’re
calling a temporary halt to NARRS 1 registrations in 2017 and will
announce amended protocols as soon as we can. All NARRS 1 surveyors will
be contacted about this by e-mail and we hope you’ll all want to take
part in the new, improved version! Watch this space for details.
NARRS PHASE 2 is continuing. The aim of NARRS PHASE 2 is to obtain population data, so squares will be revisited every year
with the emphasis on obtaining estimates of numbers (population sizes). If you know of a local site
with any amphibian and/or reptile populations – you are eligible for NARRS PHASE 2
surveys. We ask, however, that you are able to visit your chosen site(s)
at least FOUR times each year
in suitable survey conditions so that data are comparable. For more information, visit
for Surveyors and see our Training Events
NARRS PHASE 2 HERE!!
NARRS is led by Amphibian and Reptile Conservation (ARC) in partnership with ARG UK and many other partners.
Through volunteer-based surveys, we aim to monitor the conservation status of all UK amphibian and reptile
species. Click on the buttons or links to each side for more information.
