The first dataset is comprised of anonymised badger trapping records for
government and lay vaccinator groups in England. This dataset only
includes records from groups operating under Natural England licence. In
the first dataset, each record gives details of the number of traps set by
a given group at a particular location (an active badger sett or other
area of badger activity) on a single trapping night. An anonymised code
has been given to each group. Additional fields include organisation type
(government or lay vaccinator group), operational year (how many years the
group has been active), the number of traps set on a given night and the
number of badgers captured (note that this value is not the same as the
number of badgers vaccinated as over the course of a two night trapping
event, badgers trapped on the first night may be recaptured on the
second). The second dataset is comprised of summarised trapping data for
calculation of population size (based on Lincoln Petersen estimation) from
which the proportion of the population vaccinated is derived. Trapping
data have been summarised for each vaccination group in a given year; a
total of 35 rows are included. Fields in this dataset include the
anonymised code for each vaccination group, year, the total number of
badger vaccinated in that group/year combination and the fields required
for calculation of the LP estimator.
In England, all badger vaccination projects are required to submit records
of their activities as a condition of the Natural England licence under
which they operate. These records are held in an SQL database hosted by
the Animal and Plant Health Agency (APHA). The first dataset is derived
from 6352 records from groups engaged in badger vaccination between 2010
to 2015. A record is defined here as a given night of badger trapping in
a specific area undertaken by a vaccination group. Reported data include
numbers of traps deployed, organisation type, operational year, month and
number of badgers trapped. In the second dataset, as the LP Index is known
to be biased by small sample sizes, data are excluded from groups where
less than seven marked badgers were caught on all second nights of
trapping. We used records from the first and second nights of vaccination
operations only (occasionally trapping was extended to a third or fourth
night when no badgers were captured on the first two nights).
