Recent fire and cattle herbivory enhance plant‐level fuel flammability in shrublands
Abstract Question Could disturbance by fire and ungulate herbivory alter fire regimes by increasing flammability in shrublands and early‐successional forests? Location Nahuel Huapi National Park, northwest Patagonia, Argentina. Methods We compared four characteristics that influence fuel flammabilit...

Location Nahuel Huapi National Park, northwest Patagonia, Argentina. Methods We compared four characteristics that influence fuel flammability – fine fuel load, plant bulk density, percentage fine fuel, and percentage dead fine fuel – and the vertical distribution of live and dead fine fuel at recently burned (<15 yr) and unburned (>50 yr) sites, both in the presence and absence of cattle, for six resprouting species: non‐palatable L omatia hirsuta and D iostea juncea , moderately palatable N othofagus antarctica and S chinus patagonicus , and highly palatable M aytenus boaria and R ibes magellanicum .

Cattle browsing was the main driver of variability in flammability for highly palatable species, showing increased plant bulk density and percentage fine fuel in response to cattle.
