Tallest Trees in Eastmoreland could be cut down ; Three 150 foot Sequoias

3 Historic Giant Sequoia Trees said to be 158  years old, up to 150+ feet tall, & 7 feet diameter could be cut down in Eastmoreland, S.E. Portland! – by MJ Ewers, 6-28-15.

These are the tallest trees in Eastmoreland, and possibly among the oldest. (based on my Google Earth canopy height survey project). I measured the foremost of the 3 giants, at 153- 154 ft with inclinometer from 4 different angles on June 24th. This confirms, and exceeds the Google Earth 3D model of 147 -150 ft. They are approx. 58 – 60 feet in spread, and range from 78 to 83 inches DBH, diameter. (Update: Darvel Lloyd and I measured the circumference of the tallest and largest Sequoia at about 23 -1/2  feet on 6/28/15 — giving an average diameter of 7 ft 6 inches at 4.5 feet above ground).  No trees in Eastmoreland match or exceed 150 feet, based on my survey. You have to go out 1 to 2 miles radius to find taller trees than this in South East Portland. See Map below:

The tallest of these 3 Giant Sequoias may well be taller than any other tree in S.E. Portland for nearly a mile radius. Taller than any other trees in Eastmoreland proper, Woodstock Park, or the grove of Douglas firs at the Apostolic Campgrounds in Brentwood-Darlington, You don’t see trees higher than 150 feet except for one or two at Crystal Springs Rhododendron Garden,a few at Kenilworth Park, Mt Scott Park, and Sellwood Park has some firs up to 175+ ft — about 1 to 2 miles away.

Losing some of the tallest trees of inner S.E. Portland would be unfortunate. I figure, that if each of these trees is from 6-1/2 to 7-1/2 ft diameter, range from 140 – 154 feet tall, then they contain about 1,300 to 2,200 cubic feet of biomass in the trunks alone (volume of a cone). You would need a stand of about 15 – 20 big Douglas firs, 120 feet tall and 3 ft diameter each to equal the same amount of biomass as these 3 Sequoias!

  • Neighbors have raised $50,000 to protect the giant trees, but this only delays their harvest by a week! Neighbors and citizens are trying to raise an additional $900,000 to to puchase the property from the developer and possibly turn it into a small park or green space.
  • A Go Fund Me page was created to try and raise enough funds through donations to help save the Giant trees:  http://www.gofundme.com/SaveTheGiants

  • My interest in saving these trees: Having been a resident of South East Portland all my life, I had always been impressed with these 3 massive Sequoias which loom high above the Eastmoreland urban canopy. Taking the Bus line 19 up Woodstock hill, these three “wise men” jut out of the Eastmoreland neighborhood with majesty, perched atop Martins street, overlooking the neighborhood — ancient Goliath sentinels, always on guard… to be poetic. I first became aware in 2013- 2014 that these were the tallest trees in the Eastmoreland Neighborhood, while perusing Google Earth’s 3D mode, attempting to find the tallest trees in Portland. (See project on portland’s urban canopy): PDX TREES – Some Notable & Tallest Trees of Portland, Oregon Metro
East Moreland Sequoias

My initial estimate placed these trees at 138 to 147 feet high, based on Google Earth 3D, subtracting the tops, 323 ft, from the DEM ground elevation of 176 ft. However, measuring the tallest of these 3 in person with inclinometer on 6/24/15, indicates they are slightly taller– the tallest approx. 153 ft.

There are dozens of similar old Giant Sequoias sprinkled throughout the Portland metro area– Seven of them are listed as Heritage trees: Heritage Trees of Portland- Sequoiadendron giganteum

PDX Courthouse Seuoia

156 ft + Sequoia at Lownsdale Square.

There are a similar number of giant Sequoias not yet nominated as Heritage trees: A 156+ foot tall Sequoia at Lownsdale Park, in front of the Multnomah County Court House, and a 164 ft tall Sequoia at the 2700 Block of S.E. Harrison, in Milwaukie , near the Crystal Lake Apartments.
