Do Christmas Trees Drink Vodka?

(Hint: Save the vodka for your Holiday Cheer...)
Visit a 60,000-Year-Old Underwater Forest
Ancient cypress forest in the Gulf of Mexico

The ancient cypress forest found 60 feet underwater in the Gulf of Mexico, due south of Gulf Shores, Ala., is about 60,000 years old, says a team of scientists who have studied the site.
The forest appears to be a wholly unique relic of our planet's past, the only known site where a coastal ice age forest this old has been preserved in place, with thousands of trees still rooted in the dirt they were growing millennia ago. It is considered a treasure trove of information, providing new insights into everything from climate in the region to annual rainfall, insect populations, and the types of plants that inhabited the Gulf Coast before humans arrived in the new world. Scientific analysis of the site is ongoing.

Predating the arrival of humans in North America and the pyramids of ancient Egypt by more than 50,000 years, the trees discovered in the Underwater Forest date to an ice age 60,000 years ago, when sea levels were hundreds of feet lower, and the Earth was much cooler than it is today, with much of the water on the planet locked up in glaciers.
While most people think of the period from about 12,000 to 18,000 years ago when they think of "the" ice age, the planet has actually been visited by dozens of ice ages, which occur every 40,000 to 100,000 years.

Want to Plant Trees in Your Town?  
There is probably a program to do it!
And arborists can help

San Angelo: After the 2010-2012 drought, an intense windstorm in 2017 and with an average of only 22 inches of rain a year , San Angelo needed some help to reforest its public lands. Donations are accepted to plant trees and you can even request a small plaque to dedicate the tree.

San AntonioNow is a good time to plant shade trees. Planted in the fall and early winter, the trees have a chance to develop a root system before they must face the South Texas summer.  For the customers of the CPS Utility it is a good time to plant a shade tree because you can receive a $50 rebate for up to five shade trees. Plant the trees to shade your house on the south and west sides and you can reduce air-conditioning costs by 25 percent.

AustinNeighborWoods is a partnership between TreeFolks and the City of Austin to lower summer temperatures and reduce energy consumption by investing in tree canopy cover for Austin area neighborhoods. NeighborWoods is proudly supported by the Community Tree Preservation Division in the Development Services Department at the City of Austin. They distribute 4,600 free trees every year during the very best planting season for Central Texas, October 1st through March 31st.

England (the country): Aimed at local authorities, charities and community groups, this new manual provides advice on selecting the right tree for the right place in towns and cities - ensuring the views of local communities are at the heart of decision-making and residents are properly consulted before street trees are planted or felled.

Does your city have a tree planting program? Why not make a New Year's resolution to donate your arborist skills to your community next year. Call your city and ask who the person is in charge of trees then let them know you would like to lend a hand.  You can make your community a better place to live!
