MEASURING UNDERSTORY LEAF OBSTRUCTION IN ECOLOGICAL STUDIES: A COMPARISON BETWEEN TWO METHODS
: The square wooden frame and the digital photography are methods widely used to measure density or foliar obstruction of the understory (FOU) in structurally complex habitats. Here we compared these two methods by measuring FOU in two grids in the Garrafão, an area of Atlantic Forest in the Serra dos Órgãos National Park, state of
