West Texas Native Tree-Air Purification #167663

Asked February 21, 2014, 5:19 PM EST

I am looking for the best kinds of native trees to plant in my front yard to absorb or filter out street pollution. I intended to plant royal empress until i discovered it is an invasive species. Is there a fast growing tree, native to west Texas, that is superior in blocking/purifying/filtering/absorbing automobile or general pollution? Thank you for your help!

Expert Response

Urban trees For an excellent paper on all the factors to consider when choosing trees to reduce urban pollution, see this publication from Lancaster University: http://www.es.lancs.ac.uk/people/cnh/UrbanTreesBrochure.pdf You'll note there are several factors to consider for what is the "best" in terms of what. Cross checking which trees remove pollutants against the list of best trees for El Paso (http://aggie-horticulture.tamu.edu/ornamentals/elpasoplants/nativetrees.html ), it looks like a Green Ash, Hackberry, Bigtooth Maple or Red Oak  would suit the category best. But only if it is also the best choice for your specific site.  Do you have the space, location, soil, etc. to keep it healthy? So before to go buy that tree, you might also want to check on this site for location , care and needs with these resources from the Texas Tree Selector tree care information:  http://texastreeplanting.tamu.edu/ Your best choice will include not only species good at removing pollution but also ones that grow well in your particular yard. The Texas Tree Selector will help you make a good final choice.
