Jehane Samaha, MSc, Urban Forestry Technician

ISA Certified Arborist (PD-2675A), American Public Gardens Association (APGA) member, International Dendrology Society (IDS) member.

Ms. Samaha earned a Masters of Science in Forestry at the University of British Columbia (UBC) with a research focus on urban tree species selection.

Previously, she studied Environmental Science at Brown University and subsequently worked in various horticultural and research roles at public gardens. Following an internship at the Arnold Arboretum of Harvard University, she worked as a research technician investigating tree phenology and climate change as a member of the Wolkovich Lab. There she also co-founded a successful citizen science program. As a Morris Arboretum intern, she propagated woody plants and evaluated the Magnolia collection.

Her approach to urban forestry is influenced by her certificate in permaculture design (PDC), which advocates for a deep understanding of how interrelated systems of plants and people support resilience of the entire community.

With the Morris Urban Forestry Team, Ms. Samaha collects and documents high-quality tree data, writes policies and reports, and utilizes the most up-to-date scientific information to provide urban forestry recommendations.

Adi Shiloh, Martha S. Miller Endowed Urban Forestry Intern

Adi grew up surrounded by the forests and rivers of the traditional land of the Erie & Haudenosaunee, also known as Northeast Ohio. She graduated from Cleveland State University with a dual degree in Psychology and Organizational Leadership. Shortly after, she found community forestry through a Tree Steward Training, and immediately knew that trees were at the core of her life’s path. She worked for nearly two years in community forestry in Ohio, before moving to PA to become the Urban Forestry Intern at the Morris Arboretum. Adi works with the Urban Forestry team to consult and assess trees, and help write reports, tree policies and standards and other tree related documents to protect trees and other natural resources. This position is supported by the Martha S. Miller & Rusty Miller Endowment.
