Access to Nature Capacity Model

Description

Runs the access to nature ecosystem service model, generating capacity scores based on perceived "naturalness" of the habitats and their public accessibility. Calls external datasets which must be supplied by user: Public Rights of Way, CRoW, Local and National Nature Reserves.

Usage

capacity_access_nature(
  x = parent.frame()$mm,
  studyArea = parent.frame()$studyArea,
  prow,
  crow,
  lnr,
  nnr,
  res = 5,
  local = 300,
  threshold = 500,
  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 attributes HabCode_B, GI (type of green infrastructure), and GIpublic (Private/Restricted/Public access).

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).

prow

Path to folder containing Public Rights of Way data for your study area (shapefile or geopackage).

crow

Path to folder containing CRoW data (Open Country and Registered Common Land) for your study area (shapefile or geopackage).

lnr

Path to folder containing Local Nature Reserves boundaries for your study area (shapefile or geopackage).

nnr

Path to folder containing National Nature Reserves boundaries for your study area (shapefile or geopackage).

res

Desired resolution of the raster. Default is 5 m. Range recommended is 5-10m.

local

Radius (m) for focal statistics at local range (maximum distance for effectiveness). Default is 100 m.

threshold

Size (m2) below which an isolated patch is not considered able to provide the service. Default is 100 m2.

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 (arbitrary units), and one rescaled 0-100 (where 100 is maximum capacity for the area).
