This document contains graphs and tables taken from data collected from the Cedar Creek Juniper Mastication Project. QA/QC summaries on this have been broken down into three portions: “Woody Debris”, “Belt Transects” and “Plant composition”. All three are from the original data spreadsheet “CedarCreekMastication.xlxs” (file path: Rangeland responses to Fire > Woody plants > Juniper mastication > BLM > data)

A summarizing of woody debris (mean count, SE) taken from ALL combined Cedar Creek transects.

Histograms reflecting woody debris count distribution via size

Sec 2: Belt Transects

Using a bargraph to show plant intersects by species, we see the two dominant species along each transect are Rocky Mountain Juniper (Juniperus scopulorum) and snowberry (Symphoricarpos albus)

Sec 3: Plant Composition

Original dataset from CedarCreekMastication spreadsheet (PlantComp)

Objective was to find out the overall averages in cover (%) for each species within the expiremental unit. Of the 1211 observations from 5 variables I filtered the data to reflect species coverage removing all zero values as these values are irrelevant and skewing the data. This produced a breakdown version of 686 observations of 2 variables (% coverage and species)

Quick summary of forage clips taken from quadrats of each transect. Histogram reflects the distribution for forage availability before mastication treatment.

Outliers at low end (0’s) are not errors as there were quadrats without any plant life.
