Tri-Met’s Orange Line Landscapes: Clinton & SE 12th to Harold St.

This shows the banded pattern common today in long mass plantings each swath a single species.

This shows the banded pattern common today in long mass plantings each swath a single species going for a kind of landscape scale ‘graphic’ pattern that is less concerned with ‘fit’.  This is near the Clinton/ SE 12th stop.

Size matters.  In horticulture it changes everything.  Things that are inconsequential, or maybe even enjoyable in the backyard garden, can quickly become daunting or onerous when the scale is ramped up.  Working at a commercial or institutional scale has to change your entire approach to the landscape.  In a small garden it is easier to accommodate mistakes, the conflicted combinations and those issues of horticultural ‘fit’ that we missed when we design or install.  Scale, however, rubs our faces in it everyday, makes us pay with aching backs as unintended consequences play out across the thousands of sq.ft. and acres.  It becomes a matter of physical survival and undermines your professionalism.  You become perforce part laborer, part diagnostician, designer, plantsman and critic….Out of necessity you sharpen your critical thinking skills and the last thing you ever wanted, your sales skills, as you work to sell your ideas to management who are absurdly ignorant of the problems you face everyday in the field.  And, then, eventually, you retire, but you don’t turn it off…you can’t.

Which brings me to the MAX Orange Line and its landscapes.  When I did horticultural design review for large capital Parks projects, it often felt like a dueling match.  I would pour over the design, whatever the stage it was in, match that with my particular knowledge of site conditions and my maintenance experience within Parks.  I would state my concerns on paper and in meetings with the Project Managers and Architects.  I was stubborn and consistently found myself up against a process that undervalued horticulture and my input.  Good horticultural practice was regularly placed in a losing position opposite not just that of the Landscape Architects but of a very political process that tried to give the public what it wanted as long as it fit within the Architect’s vision.  Horticulture always came out a poor third, even though good horticulture always saves money in the mid and long runs.  It was exasperating.  The public, by and large is ignorant of horticultural practice and no effort is made to educate them at any level.

Revisiting Holgate Overpass: A Mistake Repeated

Holgate Overpass - the northeast approach. This was taken Aug. 28 of the landscape cut down in April showing regrowth in a hot drought year.

Holgate Overpass – the northeast approach. This was taken Aug. 28 of the landscape cut down in April showing regrowth in a hot drought year.

Holgate Overpass Update:

It finally rained this last weekend!  Somewhere around .3″.  Woohoo!  It will be the most rain that we’ve received since March.  It’s been dry!  In April the City cut down the ‘weedscape’ on the northeast approach of the Holgate Overpass.  It’s rained very little since and we’ve had record warm temperatures all summer.  No one has come back to spray, plant or do anything.  No one’s even picked up the trash.  If you compare the four ‘weedscapes’ on the two approaches they are very similar.  The NE, by volume has had the most regrowth.  This is for two different reasons: first, this site was cut earlier in the season when there was more moisture still in the soil to enable regrowth, and secondly, because the site is dominated by Blackberry and Tree of Heaven, both perennials, well established and of larger stature than the plants dominating the other approach landscapes.

The Subterranean Dance: Plants, Nutrients, Water and Their Relationship in Soil Health

The western coast of North America is home to an amazing array of landscapes each with its particular climate and range of soils.  This is in the California coastal range looking southerly towards the distant Bay area across meadow, native Coast Live Oak, Doug Fir and the Coast Redwood of the Armstrong Grove in the lower creek bottom land.

Third in the Water Series

As I seem to keep repeating, water, makes life possible. Plants and animals, with too little, die. Soil, in a very real sense is alive as well, and requires water to animate it. Without water the teeming organisms that occupy and comprise it, die or lie dormant until they are rehydrated. Topsoil, that thin layer upon which all terrestrial plants rely, is a swarming, largely invisible, community. Its effect on all life are essential and intimate. Topsoil is where all of terrestrial life is grounded. It’s health and vitality reflects that of the life on the surface including our own. As humans we are essentially consumers and, if we are to survive, stewards of the life upon which we depend. Plants are the creators. That is perhaps a bit simplistic because the relationship between plant, animal and earth is considerably more complicated. Life has evolved together, each species, each element, and, because of this, is part of an integrated whole. Continue reading →
