Anthony R. Brach

I am interested in the digitization of specimen data for understanding responses to environmental change, and the development of digital floras and interactive identification keys.

My doctoral research explored the responses of two fern species to experimental changes in nitrogen deposition and irradiance, and my masters research, the effects of watershed liming on understory vegetation. From July 1993 to October 2012, I edited treatments for the Flora of China. I have experience building interactive identification keys for more than ten years, using the DELTA editor for inputting data from descriptions and outputting interactive keys for Intkey, NaviKey, and PathKey applications.

From November 2012 to May 2013, I assisted with the digitization (minimal data capture and imaging) of lichen specimen labels, as part of the North American Lichens and Bryophytes: Sensitive Indicators of Environmental Quality & Change Project. I continue to collaborate by entering data from imaged labels via the project’s crowd-sourcing interface and for the macrofungi digitization project (for an overview of these citizen-science efforts, see
