#' Cutthroat trout and salamander length and weights in Mack Creek, Andrews Forest LTER
#'
#' Includes count and size data for cutthroat trout and salamanders in clear cut or old growth sections of Mack Creek, Andrews Forest LTER.

#' @format A tibble with 32,209 rows and 16 variables:
#' \describe{
#'   \item{year}{a number indicating the observation year}
#'   \item{sitecode}{a character denoting the coded name of sample area}
#'   \item{section}{a character denoting the section in Mack Creek (CC = clear cut forest, OG = upstream old growth coniferous forest)}
#'   \item{reach}{a character denoting the reach sampled from each section; L = lower reach (0 - 50 meters), M = middle reach (50 - 100 meters), U = upper reach (100 - 150 meters))}

#'   \item{length_1_mm}{a number denoting vertebrate length in millimeters; total or snout-fork length for trout, and snout-vent length for salamanders}
#'   \item{length_2_mm}{a number denoting snout-tail length in millimeters (for Coastal giant salamander only)}
#'   \item{weight_g}{a number denoting vertebrate mass in grams}

#'   \item{sampledate}{a date denoting the date of observation}
#'   \item{notes}{a character denoting additional comments}
