Tour des Trees – 25-year Silver Anniversary

It all began in 1992, in the Pacific Northwest Chapter, when 13 hardy souls decided they could raise money for trees by riding their bicycles from Seattle to San Francisco in eleven days. The inaugural ride was 1,050 miles. The riders averaged over 100 miles a day with the longest day being 144 miles. The first Tour des Trees exceeded their goal of $60K by raising nearly $100K. Twenty-five years later the Tour is still going strong. This year’s riders traveled a mere 578 miles in seven days and raised over $300K for tree research and education. In 25 years the Tour des Trees has raised more than $3 million dollars and riders have pedaled nearly 15 thousand miles, all in the name of tree research and education. Not too bad for a bunch of tree hugging cyclists! Read More "Tour des Trees – 25-year Silver Anniversary"

Growth Rings in the New Year

Growth Rings in the New Year

A Letter from J. Eric Smith of TREE Fund

Dear ISA Friends,

Annual growth rings in temperate-climate trees mark the increments of new wood added each year. As you all know, we can learn a lot by studying a tree’s annual rings: its age, the climates it has thrived in, its relationships with symbiotic organisms, and even the nature and quality of its interactions with humans.

What would the TREE Fund's 2016 annual growth ring tell you about our nonprofit organism if you peeked inside?

I’ve been thinking about the imagery of annual growth rings as I reflect on my first year with TREE Fund, much of it spent travelling to meet, listen to, and learn from the tree care community. We’re a year older now, so what would our latest annual growth ring say about our nonprofit organism if you peeked inside?

growth-ring-closeupFirst off, it would show that we’re growing in both resources acquired and resources disbursed, and that the ratio of those two flows is trending in a healthy direction, as we’re working to get more of every dollar we raise back out to support you in the field. We’re doing this by growing new branches and adding new coverage — additional programs, larger grants, and more awards — all to the benefit of the professionals who shelter under our canopy of knowledge.

To sustain this healthy growth, we’re continuing to “open the circle” in a healthy, non-invasive fashion, thereby allowing new friends and supporters to build atop our strong roots, injecting new revenue streams that will ensure we remain vibrant for many years. Trees are long-lived organisms — just as an endowment fund is — and we exist solely to provide long-term support for tree care professionals like you, helping you adapt to the ever-evolving challenges facing our urban forests.


Of course, there’s another meaning to “annual ring” — namely, a once-per-year call — and I’m hoping you’ll indulge me on that front here as well. As we move forward and upward, solid sustenance sets the stage for potentially transformative growth in 2017, so we respectfully request that you consider a gift of at least $100 to our 2016 year-end appeal. Please make your contribution at today. With your support, growth can ring in the New Year from day one.

With best regards, and deep gratitude,


J. Eric Smith, President and Chief Executive Officer

Opportunity to Join the PNW Board and Get Involved in the TREE Fund

Tree FundAfter eight years as the TREE Fund Liaison for the PNW Chapter, I am stepping down. This was a tough decision because I truly believe in the TREE Fund mission to support scientific research and disseminate knowledge in the fields of arboriculture and urban forestry.
