500 Miles for Tree Research
2012 Tour des Trees
Benefits the Tree Fund

You can support Salvador Alemany, Pete Smith and all the Texans in their ride to raise funds in the Tour de Trees.

The STIHL Tour des Trees is a weeklong, 500-mile cycling event held each year to benefit the Tree Research and Education Endowment Fund (TREE Fund). Since its inception in 1992 the Tour des Trees has raised more than $5 million for scientific research and education programs related to arboriculture (the science of caring for trees in a landscape) and urban forestry.

Each full-Tour cyclist commits to raising $3500, and the proceeds of the event support the discovery of better methods for propagation, planting and care of urban trees. The Tour also funds education programs aimed at connecting young people with the environment and with career opportunities in the green industry. With itineraries in the U.S., Canada and abroad, the legacy of the Tour des Trees includes a growing urban forest planted by its cyclists and a new appreciation among the residents of its destination communities for the trees which shade their lives.

Texas drought takes toll on the urban forest,
millions of shade trees dead

The Texas Forest Service estimates 5.6 million trees that once shaded homes, streets and parks in communities across Texas now are dead as a result of last year’s unrelenting drought.


Texas Forest Service findings include:

·         An estimated 5.6 million trees in urban areas were killed as a result of the drought. This figure may represent as much as 10 percent of the total number of trees that make up the urban forest.

·         Because these dead trees are in populated areas, many are a safety issue and will need to be removed. The estimated cost to remove these trees is $560 million.

·         Urban trees do more than just beautify your community. They also provide economic and environmental benefits like cutting your heating and cooling bill, cleaning the air you breathe and water you drink and boosting your property values. The estimated loss of economic and environmental benefits provided by these trees is roughly $280 million per year.

Epic Drought In Texas
Water Trees Now!

We’ve seen some rainfall in parts of the state over the past couple of months … So what does that mean for the historic drought we keep hearing about?  

The rain is welcome and has actually improved drought conditions in North Texas, according to the most recent drought monitor.  

But we’re not quite seeing the light at the end of the tunnel just yet. Texas Forest Service Predictive Services Department Head Tom Spencer said nearly all of the state remains in extreme to exceptional drought – and the onset of a second La Nina event means Texans are likely to continue seeing below-normal precipitation through May.

Click here for tips on watering trees in this exceptional drought.

Thank you for helping our valuable Texas trees.

Texas Wildlife and Woodland Expo

Texas Wildlife and Woodland Expo & Spring Fling is designed to help families learn a little about the land on which they live — and how to best take care of it — through hands-on clinics, live demonstrations and children’s activities.

Though Expo & Spring Fling is an annual event, this year organizers have placed a special emphasis on helping residents recover from drought and wildfires.

It doesn’t matter if you’re a nature lover or outdoor enthusiast. It doesn’t matter if you’re an urban homeowner or a rural landowner. It doesn’t matter if you’ve got just one tree in your yard or thousands of them. Texas Wildlife and Woodland Expo & Spring Fling has got you covered.

We’ve got free, hands-on clinics and live demonstrations that will teach you how to nourish your plants and trees, attract wildlife to your property, collect and use rainwater and protect your home from wildfires.

And don’t forget to take your little ones to the Family Adventure Zone, where they can climb a rock wall, take a peek at a live screech owl and learn how to kayak.

At Expo & Spring Fling, you’ll play for a day but learn for a lifetime.
