Species cover

Percent cover of each species (%)

The number of times an individual of each species was encountered at each of the 100 points along the transect line

Evaluate the compositional differences between intact chaparral and treated fuel break

Untreated vs treated

NMDS
 
Lifeform cover

Percent cover of each lifeform category (%)

The number of times a lifeform category was encountered at each of the 100 points along the transect line

Evaluate the difference in lifeform cover between intact chaparral and treated fuel break

Untreated vs treated

ttest = all lifeform categories, except Wilcoxon ranksum for tree cover

Squareroot: shrub cover, herb cover

Evaluate the change in lifeform cover due to shortduration goat grazing

Pregrazing vs postgrazing

ttest

Squareroot: herb cover, tree cover

Species richness

Number of species within each lifeform category (count)

Number of unique species encountered along each of the 100 points along the transect line

Evaluate the difference in species richness between intact chaparral and treated fuel break

Untreated vs treated

ttest = all lifeform categories, except Wilcoxon ranksum for tree richness

Squareroot: shrub richness, herb richness

Evaluate the change in species richness due to shortduration goat grazing

Pregrazing vs postgrazing

ttest = all lifeform categories, except Wilcoxon ranksum for tree richness

Squareroot: dead shrub richness, herb richness; Sin: live shrub richness

Lifeform height

Maximum height for each lifeform category (cm)

Average maximum height for each lifeform category encountered along each of the 100 points along the transect line

Evaluate the structural differences between intact chaparral and treated fuel break

Untreated vs treated

ttest = shrub height; Wilcoxon ranksum = herb height

Squareroot: shrub height

Evaluate the structural differences caused by shortduration goat grazing

Pregrazing vs postgrazing

ttest = shrub height; Wilcoxon ranksum = herb height
