Analysis of trends and current amounts of protected lands and waters in B.C.

A set of R scripts to complete the analysis behind the Environmental Indicator Protected Lands & Waters in B.C., published by Environmental Reporting BC in June 2016.

Note: Moving forward this analysis and indicator will be updated using the analysis and approach found here.

Usage

Data

The analysis uses data from several sources; they should be downloaded and stored in the data folder:

• Canadian Council on Ecological Areas (CCEA) shapefile database of protected areas in Canada
• B.C. Government Conservation Lands (Licence: Open Government Licence - British Columbia)
• B.C. NGO Conservation Areas Database — Fee Simple Areas
• Ecoregions - Ecoregion Ecosystem Classification of British Columbia (Licence: Open Government Licence - British Columbia)
• Biogeoclimatic Ecosystem Classification (BEC) Map (Licence: Open Government Licence - British Columbia)

Code

There are four core scripts that are required for the analysis; they need to be run in order:

• 01_load.R - unzips the data files in the data folder
• 02_clean.R - cleans and prepares the spatial data for analysis, especially resolving overlaps among types of protected area designations
• 03_analysis.R - performs the spatial intersections and creates data summaries
• 04_plot.R - creates plots for communicating the results

The file fun.R contains a few custom functions required for the analysis.

Required R packages:

Spatial packages:

sp
rgdal
rgeos
raster
maptools
geojsonio
bcmaps
rmapshaper

General data manipulation packages:

dplyr
tidyr
readr

Plotting packages:

ggplot2
RColorBrewer
ggthemes
envreportutils

Most packages used in the analysis can be installed from CRAN using install.packages(), but there are a few you will need to install using devtools:

install.packages("devtools") # If you don't already have it installed

library(devtools)
install_github("bcgov/envreportutils")
install_github("bcgov/bcmaps")

Other required software

You will also need the mapshaper node package, and for this you will require Node.js to be installed. You can install it from here, then on the command line type:

npm install -g mapshaper
