Today’s Pond vs. the Pond of the 1960s
Scour the internet and local resources for old pictures of the Millrace Pond
Lane County Historical Society
Don Hunter Collection
Take “before and after” style pictures
Identify plants in old pictures
I had assumed that the vegetation was far older than that
Made plant ID easy
Grass and Dirt to Canopy in 54 years
Today’s Pond vs. the Pond of 500 Years
The Quest for Analogous Ponds
On Analogous Ponds
I needed to find a pond/slough that would be a
good representation of what the Millrace Pond
would have looked like 500 years ago.
I was looking for a pond that had not beenaltered much since then, and I was told about two.
One 30-meter transect parallel to water’s edge
One 5-meter transect perpendicular to water’s edge every 5 meters along the 30-meter transect
Millrace Pond Transect
Analog 1: Mt. Pisgah Water Garden
Analog 2: Willamette River Slough
Initial Observations and Changing Ideas
Initial findings showed no obvious change in vegetation type in lateral transects
Decided to break parallel transect up into 5-meter sections and add percent cover calculations from those to lateral transect data
The Millrace Pond was largely planted
Less native species
Would have had far more canopy cover from
Would have had a shrub layer of
Wouldn’t have any
