Become a citizen scientist with the Claremont Urban Arboretum. In 2015, Environmental Analysis students of the Claremont Colleges, Naomi Bosch, Alison Marks, Sydney Stephenson, Nadine Lafeber, and their adviser Ben Wise created the Claremont Urban Arboretum using the 2014 Street Tree Inventory for the City of Claremont. Since then, many trees have been removed to drought dead and disease and many new trees have been planted - we still believe this is a useful learning tool to become familiar with trees in Claremont.
