Fragment habitat along barriers — sf_fragment

Removes barrier areas from buffered habitat and splits the result into individual polygon fragments.

Usage

sf_fragment_habitat(habitat_buffered, barrier)

Arguments

habitat_buffered: SF object. Buffered habitat geometry.
barrier: SF object. Barrier geometry (e.g., roads).

Value

SF object with individual habitat fragments, each with a unique ID.

Examples

lizard_habitat_sf <- terra::as.polygons(example_habitat(), dissolve = TRUE) |>
  sf::st_as_sf()
lizard_barrier_shp <- example_barrier_shp()
