The title is in the Skidegate dialect of Xaayda /Haida for Restoring Balance.
The Llgaay gwii sdiihlda project was a Parks Canada Agency funded project (2014-2020) that attempted to restored the balance in the coastal forest ecosystem on six islands of the Haida Gwaii archipelago within the National Park Reserve, National Marine Conservation Area Reseve and Haida Heritage site known as Gwaii Haanas. The project goal was to eradicate all invasive Sitka black-tailed deer from six islands where their persistent browsing had greatly diminished the understory and young trees in the forest and negatively impacted biodiversity. The code in this repository used data from that project to determine the efficacy of the different eradication methods used during the project. It also looks at the cost through time of the different methods and estimates the likely number of deer remaining on the islands at the time of the project’s cancellation (while it was still incomplete).
In order to install and run the code, you will need to open the
zzz-run-all.r file which has the order to go for running the code. The
csv files with the final data from the project will be accessed through
the open data portal of the Government of Canada. The first call is to
run install-packages.R which will install all dependencies beyond base
R.
This project had many collaborators both operationally in the field and for the analysis. The paper for which this analysis was done has a full list of acknowledgements. For this analysis, the main programmer was Dr. Joe Thorley with database programming assistance from Seb Dalgarno, both of Poisson Consulting Ltd. The data cleaning and tidying was done by Patrick Bartier, Charlotte Houston, Robyn Irvine and Christine Bentley of Parks Canada.
