demand_pollination: Pollination Demand Model

In ecoservR/ecoserv_tool: Natural Capital Mapping Toolkit (UK)

Pollination Demand Model

Description

Runs the pollination ecosystem service model, generating demand scores based on areas assumed to require insect pollination (crops, gardens, allotments).

Usage

demand_pollination(
  x = parent.frame()$mm,
  studyArea = parent.frame()$studyArea,
  res = 10,
  dist = 800,
  projectLog = parent.frame()$projectLog,
  runtitle = parent.frame()$runtitle,
  save = NULL
)

Arguments

x	A basemap, in a list of sf tiles or as one sf object. Must have attribute HabCode_B.
studyArea	The boundaries of the site, as one sf object. The final raster will be masked to this shape. For best results this shape should be smaller than the basemap (which should be buffered by typically 300 m - 1km to avoid edge effects).
res	Desired resolution of the raster. Default is 5 m. Range recommended is 5-10m.
dist	Distance threshold from habitats requiring pollination. Default 800m.
projectLog	The RDS project log file generated by the wizard app and containing all file paths to data inputs and model parameters
runtitle	A customised title you can give a specific model run, which will be appended to your project title in the outputs. If comparing a basemap to an intervention map, we recommend using "pre" and "post", or a short description of the interventions, e.g. "baseline" vs "tree planting".
save	Path to folder where outputs will be saved. By default a folder will be created using your chosen run title, prefixed by "services_". Do not use this argument unless you need to save the outputs somewhere else.

Value

Two rasters with capacity scores: one with raw scores (0-1: likelihood that a pollinator will visit a pixel), and one rescaled 0-100 (where 100 is maximum capacity for the area).
