Description Usage Format Source
The data are simulated from a camera-trap survey of leopards in the Boland region of South Africa, using a fit to the real data to create the simulated population. Cameras were checked weekly and data recorded in binary format (i.e. only whether or not an animal was detected on each occasion, not the number of detections within occasions).

An object containing list with the following two data objects.
Boland.CH1
: an secr
capture history object with camera-trap
detections of leopards in the form of binary data over 13 occasions.
Boland.mask1
: an secr
mask object for the data in Boland.CH
.
It contans the following covariates:
alt
:altitude
Landuse
:Landuse category (1=Natural, 2=Cultivated, 3=Degraded, 4=Plantation)
Natural
:binary variable: 1=Natural land use category, 0=not
dist2.Urban
:distance to closest Urban land use category cell
dist2.Water
:distance to closest Water land use category cell
dist2.Natural
:distance to closest Natural land use category cell
LUfactor
:Landuse category as a factor variable
Boland.mask1
was provided by the Cape Leopard Trust Boland Leopard Project
(http://capeleopard.org.za/research/leopard/boland). Boland.CH1
was simulated using
a model fitted to the real data.
