Program: Hidden Prairie: Photographing Life in One Square Meter
Presenter: Chris Helzer, director of science for The Nature Conservancy in Nebraska
In 2018, Chris Helzer embarked upon a journey to photograph all the beauty and diversity he could find within a single square meter of prairie in Aurora, Nebraska. The project was intended to share with others the diversity and value of prairies, but it ended up inspiring Chris much more than he’d expected. He came away with thousands of photographs, including more than 100 species, but the numbers represented only a small part of the results. By sitting quietly and intently watching a small space, Chris was able to see the prairie in a much more intimate way than he was used to. He had a window into the lives of the tiny organisms that make up prairie communities and got to follow both their stories and the story of the prairie itself through the seasons. The project has resonated with others well enough that it has been turned into a book and is the topic of an upcoming museum exhibit and potential documentary.

Program: Snow Brings Flowers: Sycan Marsh Preserve Presenters: Sarah Ratay At the East edge of the Cascades and a mile high sits The Nature Conservancy’s 30,000-acre Sycan Marsh Preserve. It’s been a wild year with a plague of grasshoppers and the Bootleg Megafire burning onto the preserve. This important landscape-scale site is helping inform the forest management debate. Hear from the Preserve Steward, Sarah Ratah, about the interesting botanical treasures and challenges of the remote preserve.

Sarah Ratay has spent 25 years working in botany and conservation. She studied the rare plants of the California Islands for a master’s project at UCLA and helped with conservation projects in the amazing Baja peninsula. Moving to the other end of the California Floristic Province, Sarah’s job is a never-boring mix of prescribed fire implementation, maintenance of an off-grid field station, fence repair, and a lot of snowplowing!

Meeting: Siskiyou Chapter Member Meetings will resume after the holidays on the fourth Thursday of the month in 2022.

William Theodore Schattenkerk
It is with sad hearts that we report the death of William Theodore Schattenkerk. Ted's life accomplishments were many. He loved hiking, including a 287-mile portion of the Appalachian trail in 1950 with a friend. Ted was in the U.S. Army in the Korean War, worked his way through college, and achieved a B.S. degree from Oregon State University in Range and Wildlife management. He worked for the U.S. Forest Service and Bureau of Land Management for many years. Ted and Dorothy have volunteered as members of NPSO Umpqua Chapter since 1989 and Ted led many wildflower field trips. His botany skills were well known. He narrated natural history on the Shobu to Roseburg Sister City bus tour in Oregon and later traveled to Japan with the Sister City group. He also helped at the Glide Wildflower Show for many years. Ted and Dorothy and family lived in Corvallis, Albany, Bend, Star Ranger Station on the Upper Applegate River, Klamath Falls, Pendleton, and Winston.
Ted was 92. For more about Ted's life go to
