Data collection in 2020 used a early development version of the digital data sheet. 
This generated data with a different format from later years and included some potentially challenging issues. 
Our team corrected these issues and excluded erroneous data. 
The zip file contains the cleaned, corrected data plus an R / RStudio notebook with the code we used to make these corrections.

In November 2023, we made corrections to land management unit and subunit names.

The following corrections were made to unit names at Stone Lakes NWR (*old unit name was moved to subunit name):
	- *"HQ-5" ~ "Headquarters Unit"
	- *"HQ-6" ~ "Headquarters Unit"
    	- *"HQ-7" ~ "Headquarters Unit"
    	- *"Lewis 1" ~ "Beach Lake-Lewis Unit"
    	- *"Lewis 2" ~ "Beach Lake-Lewis Unit"
    	- *"Lewis 6" ~ "Beach Lake-Lewis Unit"
    	- "Beach Lake Unit" ~ "Beach Lake-Lewis Unit"
    	- *"Beach Lake 1" ~ "Beach Lake-Lewis Unit"
    	- *"Beach Lake 2" ~ "Beach Lake-Lewis Unit"
    	- *"Beach Lake 3" ~ "Beach Lake-Lewis Unit"
    	- *"LIC" ~ "South Stone Lake Unit"

The following corrections were made to subunit names at Stone Lakes NWR:
    	- "HQ - 1" ~ "HQ-1"
    	- "HQ - 2" ~ "HQ-2"
    	- "HQ - 3" ~ "HQ-3"
    	- "HQ - 4" ~ "HQ-4"
    	- "HQ - 5" ~ "HQ-5"
    	- "HQ - 6" ~ "HQ-6"
    	- "HQ - 7" ~ "HQ-7"
	- "22" ~ "Lewis 6" (if unit name was Lewis 6)
	- "22" ~ "Lewis 1" (if unit name was Lewis 1)
	- "57" ~ "LIC"
	- "27a" ~ "HQ-7"

In August 2024, corrects to land management units and subunit names were made for Kern NWR.
Corrections changed unit and subunit names to seperate numbers and letters with "-", such that 4A becomes 4-A and 14E-1 becomes 14-E-1.
