Chaparral Transect - ecology lab with Thacher students

Transect field work with students from the Thacher School, Ojai, California.

Calculating biodiversity in two sites in the chaparral ecosystem. The first is undergoing secondary succession after being cleared by a bulldozer in the spring of 2009 in order to establish a firebreak (wildfires are frequent in the chaparral). The second represents an intact ecosystem with higher biodiversity and plant density, having reestablished after a wildfire in the late 1990s.

Data was collected to determine coverage of species, density, frequency and diversity (according to the Shannon-Weiner Diversity Index). The most inspiring example of transects are those conducted by Michael Fay, such as the African Megatransect and the Redwood Transect.
