I just wanted to insert my opinion. I'm not advocating that people should stop using Cedar because it is beautiful. I wanted to share my ecological experience with what I have witnessed in the harvesting of Cedar.
The long flat Cedar we use in the floral industry is a variety called Port Orford Cedar. It grows along the Cascade Mountains in the North West. The trees that are harvested usually come off private land but permits can be obtained to harvest off of public lands. The Port Orford Cedar trees have been in trouble for years. Harvesters that cut the Cedar foliage track funguses on their shoes that attacks the roots of the trees. I have not checked the recent data, but research I ordered back in 1998 showed that 60% of the Cedar population was either dead, or was dying. I directed my researcher to visit areas that were previously harvested and infact the researcher noted that all the trees harvested were dead. He noted that the trees were shaved of limbs or cut down and shaved.
I was the CEO of a lumber company that owned 70,000 acres in Oregon. My job was to create a company that harvested foliage and preserve them with glycerin. I hired a Agricultural Scientist that I relied closely on both for quality product development but also to develop sound environmental policies that addresses sustainable practices. I personally befriended a group of local harvesters that knew the southern Oregon land quite well, due to many many years of harvesting. On numerous occasions I would accompany them on harvest runs. For them to make any money the best choice for them was indeed to cut the tree down and strip. In areas that groves of Cedar trees were indeed cut and stripped there were no seedlings or young trees to replace because once the groves were gone, the undergrowth replaced and chocked out every thing else. Not only did I see this with the Cedars, but I also saw this with the berried Junipers in the high desert areas. The harvesters would simply push the trees over with their trucks and strip them. Sad thing is that Juniper trees that are harvested are one to two thousand years old and only stand fifteen to twenty feet tall.
I must say this because in a way I am getting back at what these people put me through. At first I looked the other way because it was my job to make this company successful. My division was housed within a huge facility that manufactured veneer to the paper rolls that make up paint roller brushes. The company was operating at a fraction of it's former glory so much anticipation and money was given to me to make it work. My main product was preserved Salal and Cedar. I invented a process to preserve Manzanita to keep it's foliage on. At times our largest runs were 10,000 pounds per day. This is a very small figure compared to the fresh demand on our forest overall. After witnessing this mill dump resins into areas that were within a mile from the Pacific, and going home each night with cloths tinted red and blowing red buggers because of the resin fumes from the paper injection lines, I started to object to these practices. Who among you would not of when a large percentage of workers even the President's own wife died of cancer. And then start to demand sustainable harvesting foliage? forget it. Top that off with I was only allowed to hire mill workers and former mill workers who basically stared at a giant machine with teeth that screamed while it tore into logs. Trying to motivation people to use two hands to increase production instead of one, dam easterner, fancy bastard. The mill itself caught fire and was completely demolished which made my resignation easy.
My opinion, Salal is sustainable, sheet moss is sustainable, Break Fern, Braken Fern, Huck, all undergrowth, all sustainable. Holly is agriculturally grown. Your Firs, not sure how thats doing, no experience. Manzanita, here again, a three foot branch is one to two hundred years old and I am not aware of any studies although they must exists because it's illegal to cut on public lands. I believe our use of Cedar will eventually deplete it's source.
Please make your own decision with this information.
I was fortune with greens this year. The former owner of my property planted cedar trees, and holly bushes many years ago so I have a long time source. However there is a Hydrangea company on the southern Oregon Coast that I befriended that advertises in local papers for people to cut from their properties ornamental cuts like Callas, Holly, Hydrangea in exchange for purchase certificates in their store. This process works very well for them. One could offer cash for product and still save money. I just think this is a good way to change our footprint and help our local economy.
