Haley Spadafora (she/her)

Forest Field Coordinator

Growing up in the PNW, Haley hiked constantly, but was often distracted from the destination by animal sign and goopy fungi. She holds a special spot in her heart for the small or less charismatic organisms in the woods. These small passions grew into action as she worked with local environmental organizations, such as watershed councils, local parks and rec, and the Oregon Zoo. She holds a BS in Conservation Biology and a Master of Curriculum Development and Environmental Education, and is excited to put them to use to help Bark achieve its goals. She is ready to help people experience the forest and understand ecosystems in a way that inspires a deeper connection with nature.

Christine Jervis (she/her)

Operations Manager

Christine joins Bark from the renewable energy sector where she was working toward a brighter climate future as an operations manager. She enjoys creating and maintaining processes and systems to ensure that her co-workers are set for success. Christine also brings over 10 years of experience and passion for connecting people to nature through informal education and empowerment. In earning her master’s in biology, Christine was privileged to learn about community-based conservation efforts around the world. Working with Bark allows Christine to connect her enthusiasm for operations to a shared vision for the future that challenges traditional conservation and prioritizes connection to place. When not at work she’s probably at the barn with her two horses or running around looking for birds.

Jordan Latter (he/him)

Forest Watch Coordinator

Jordan began his time at Bark as a volunteer, participating in forest and wetland surveys and interacting with Bark staff and volunteers. He quickly fell in love with Bark’s mission and vision for the future. Jordan’s passion for forest ecology and management began as a wildlife technician for the Forest Service, studying spotted owls and fishers amongst the granite peaks of the Sierra Nevada mountains in California. That passion turned to conviction while earning a Master’s degree studying sustainable ecosystems management at Harvard University Extension School, where his Master’s project focused on understanding the nuances of forest thinning practices on federal lands across the Pacific Northwest. A self-proclaimed “forest nerd,” he loves talking about forests and challenging contemporary perspectives on conservation. In his free time, Jordan loves hiking, backpacking, watching baseball, staring at trees, and seeking out old forest remnants.

Meg Waller (she/her)

Field Survey Coordinator

Hailing from the swamps of North Florida, Meg solidified a love of nature at a young age. After moving to the San Francisco Bay area in 2011, she started her fine gardening career and fell in love with the flora of the west coast. Meg moved to Portland in 2018 to attend PSU and graduated in 2022 with a Bachelors in Environmental Science. Alongside hydrology and ecology classes, she fell even more in love with plants and developed a keen interest in wetland ecosystems specifically. During that time, she volunteered regularly with Bark, bringing her adventure pup Japhy along on many timber sale surveys and camp outs. As Barks new Field Survey Coordinator, Meg is excited to use her environmental science knowledge to foster and expand Barks volunteers love of and interest in the beautiful nature of Mt. Hood.
