economics – Is the value of a tree $193,250?

without comments

Here is an interesting sign I first saw on Facebook. There will be much quibbling over the numbers, but one thing remains clear: Mature trees have great value for many reasons.

There is a sign, at the Eden Nature Park & Resort in City of Davao, Philippines, that says this:

Of concern to all! A tree is worth $193,250

According to Professor T.M.Das of the University of Calcutta. A tree living for 50 years will generate $31,250 worth of oxygen, provide $62,000 worth of air pollution control, control soil erosion and increase soil fertility to the tune of $31,250, recycle $37,500 worth of water and provide a home for animals worth $31,250. This figure does not include the value of fruits, lumber or beauty derived from trees. Just another sensible reason to take care of our forests.

The figure, sometimes incorrectly quoted as $196,250, is cited at various green blogs, and sold on a bright red poster at Singapore Zoological Gardens, but i haven’t been able to find the study behind it.

So is a tree living for 50 years worth $193,250?

(1) Walk with the Trees in W.C. Reed Park

without comments

Here is some ancillary material Larry Cornett posted to this coming Saturday’s Facebook event. I present it here so that it will be available on the internet for a long, long time. I think the reasoning here is incredible. Whenever federal money shows up, common sense, individual rights, and intrinsic values fly out the window.

Larry Cornett

US EPA currently plans to cap Reed Park and remove most of the trees. Reasons given for removing the trees include:
* It would cost money to save them
* Only a few people at public meetings focused on saving the trees.
* The roots of trees only extend 8” below the surface and putting two feet of fill above the roots of the trees to cap the soil would deprive them of oxygen and eventually kill them
* Many of the trees are old…
* Some trees are sick or dead
* Some species of trees are undesirable
* Some of the trees are not structurally sound and could fall on children
* If a tree blows down, exposing the roots, subsurface contamination would also be exposed
We need to have activists, ecologists, arborists, and others accompany the forester and EPA in the park on Saturday.
A previous brownfields study in the park showed concentrations of polynuclear aromatic hydrocarbons (PAH) above those acceptable for direct contact in the fill material sampled to depths of 2’ or 4’ in most of the park. Three to six inches of grassy topsoil has been covering most of the surface of the park and subsurface fill material for about 50 years or more. Portions of the park are also covered with concrete or sand (in the baseball diamond).
The topsoil was never separately analyzed to determine if it presents a significant risk from direct contact. Fungus and other microorganisms in grassy topsoil have been found to destroy PAHs at a rate of 0.2% to 17% per month. Microorganisms associated with tree roots can also destroy PAHs. For details, see

Until the topsoil, etc. are sampled and analyzed, NO SIGNIFICANT RISK FROM DIRECT CONTACT WITH THE SOIL AT THE SURFACE OF THE PARK HAS BEEN ESTABLISHED, although there would be a need to rebury or treat contaminated fill material that would be excavated where and when the City does any construction in most of the park.

WikiName explicates our “Teagan”

with one comment

We have a new granddaughter this past year, and her name is Teagan. Here, on, is a great research resource for name origins, spellings, meanings, namesakes, and name-alikes.


Tegan comes from the Welsh word teg, which means “beautiful”[1] or “fair.”[1]

As a surname, Tegan may be related to the Irish name Tadgh or Taidgh, which means “poet.”[1] Some of the variants are Teigue and Teige, which could have transformed into Tegan or Teagan.[1] As a surname, it most likely arose as a patronymic, McTeague or McTague, meaning “son of Teague.”[1] The surname is Irish in origin, specifically from the region of Connacht.[1]

Usage of Tegan as a feminine name is modern.[1] Historical usage is probably a mistranslation of a similar name, such as Tegau.[1]


In the United States, the spelling Teagan is more popular than Tegan. Tegan first appeared on the top 1000 chart of most popular baby boy names in the year 2007, ranking at number 985. As a girl’s name, the spelling Teagan first appeared on the top 1000 chart in 1999. Popularity has steadily risen. In 2007, Teagan was the 408th most popular name for baby girls in the United States. As a boy’s name, the spelling Teagan appeared on the chart in 2004 and ranked at number 677 in 2007.[1] Like other contemporary names such as Jayden and Riley, both the gender and spelling are just a matter of preference. The more it is used, the more likely it is that one gender and spelling will become conventional.

Tegan is a very popular girl’s name in Australia and New Zealand. It reached a high point as the 84th most popular name in both countries, during 1999 in New Zealand, and 1997 in Australia.[1]

Tegan is a popular girl’s name in Canada. It was most popular in 1997, when Tegan was the 328th most popular girl’s name in Canada. Popularity slipped a bit, but it remains a top 1000 name. In 2005, Tegan ranked at number 493. It has also begun to see usage as a boy’s name. In 2005, Tegan was the 574th most popular boy’s name in Canada.[1]

rule #1: never forget who you are

with 12 comments

Who knew that I would have to be reminded by my husband Tim of what is so important? I am fortunate to have the most wonderful care here (at MetroHealth in stroke rehab), but today this story is about my nurse Michelle.

Yesterday, she spent quite a bit of time with us telling us about Foster and Kleiser’s billboard business and about her uncle who was a poster artist. I believe I may have known him during the political campaigns of the ’70s, but that’s a blog for another day.

So yesterday, when we were having this conversation, I insisted on continuing to call her Marjorie even though I insisted I knew her name was Michelle. I said that Marjorie was a beautiful name and that it would be a good name for her.

To be truthful, I am not sure that I could get "Michelle" to stick in my head. But, what I didn’t realize was that I had forgotten what I had always prided myself on: Remembering peoples’ names. I am putting it in my head early, I have done this since 1972 when I first started student teaching: People’s names are who they are.

I grew up with Mom and Dad, who always were very centered on making sure that people were included and that new people were welcome. Thanks to Tim, I didn’t forget the biggest part of me and I won’t forget Michelle’s name, I know I won’t.

Through the days, I’ll be writing more little snippets, but they may be much different from what you remember, but remember, after all, this is my experience.

Wow, is it great to get back to writing!
