Analysis of land designations that contribute to conservation

This repository contains R code that calculates summaries of the amount of land designated in B.C. that contributes to conservation. It supports this Environmental Reporting BC indicator.

Usage

R packages required:

Other than bcmaps and envreportutils, all required packages are available from CRAN

• bcmaps (install with devtools::install_github("bcgov/bcmaps"))
• envreportutils (install with devtools::install_github("bcgov/envreportutils"))
• geojsonio
• rmapshaper
• feather
• readr
• dplyr
• tidyr
• sf
• ggplot2
• ggpolypath
• magrittr
• ggthemes
• svglite

Data

The inputs required to run this analysis can be obtained by downloading the data via the B.C. Data Catalogue. They are released under the Open Government Licence - British Columbia:

• designatedlands.gpkg - the land designations layer
• lands_bec.gpkg - the land designations layer intersected with BEC.
• lands_eco.gpkg- the land designations layer intersected with ecosections.

Place these in the data folder of this repository. You will also require BEC_BIOGEOCLIMATIC_POLY.gdb from here and ERC_ECOSECTIONS_SP.gdb from here

The data-raw folder contains a file sources.csv that lists all of the source land designation layers used in the analysis.

Running the analysis

• Run the 01_clean.R file to prepare the data. Note that this will take a long time (several hours)
• Run the 02_analysis.R file to calculate the summaries.
• Summary csv files are copied to the out directory, and summary tabular objects for use in the land designations Shiny app are copied to the out-shiny directory.
• Run the 03_output_static.R script to create outputs (png maps and graphs etc).
• Run the 04_output_shiny.R scrip to generate the objects required for the shiny app. This will also copy the files from out-shiny to the ../land-designations-shinyapp/app/data folder, assuming the folder exists in same parent directory as this repository

Designated Lands Python script:

Input data was created by running the python script here. Please note that the code there is still being developed to make it more efficient.

It was run using the following commands:

## Download the Biogeoclimatic Zone layer from here: 
## https://catalogue.data.gov.bc.ca/dataset/biogeoclimatic-ecosystem-classification-bec-map
## and store it in your working directory

## Download the Ecosection layer from here: 
## https://catalogue.data.gov.bc.ca/dataset/ecosections-ecoregion-ecosystem-classification-of-british-columbia
## and store it in your working directory
