In david-borchers/secrgam: Spatially Explicit Capture-Recapture with Generalised Additive Density Models

Description

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, but using a more extensive array of (simulated) camera traps than was used on the real survey. 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).

Usage

data(Boland.leopards2)

Format

An object containing list with the following two data objects.

Boland.CH2:

an secr capture history object with camera-trap detections of leopards in the form of binary data over 13 occasions.

Boland.mask2:

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

Source

Boland.CH2 and Boland.mask2 were simulated from data provided by the Cape Leopard Trust Boland Leopard Project (http://capeleopard.org.za/research/leopard/boland).
