Some Biogeographers, Evolutionists and Ecologists:
Harshberger, John William (United States
botany, phytogeography, conservation
Apart from occasional trips out of the country to
collect specimens, Harshberger spent his entire life in the Philadelphia
area, including a long-term association with the University of Pennsylvania,
first as a student, and then as faculty member. Industrious and with catholic
interests, he worked in the areas of mycology, economic botany, phytogeography,
phytopathology, conservation, ecology, and floristics. His most important
scientific work was probably his Phytogeographic Survey of North America,
published in 1911, but his most influential and best known study is his
Vegetation of the New Jersey Pine-Barrens, which not only described
the area in an educated layperson-accessible fashion, but developed a
model of the environment's ecological evolution and brought attention
to it in conservation terms.
