In the July 2019 issue of ISA Arboriculture & Urban Forestry magazine, Hossain, Stuhlinger, Olson, and Babst contributed, “A Comparison of Indirect Water Devices for Benefiting Newly Transplanted Urban Trees.” Urban trees often undergo a period of post-transplant stress which is exacerbated by a water-limited environment. Watering devices are available to help a newly planted… More
If you are of a certain age (like me), you remember when shopping malls were the place to be. However, online shopping and cultural changes have greatly impacted the popularity and profitability of malls, resulting in vacant storefronts and little foot traffic. Now, hundreds of “dead” and dying malls sit decaying throughout North America –… More
1: Can Silva Cells go around utilities? Yes, our modules can be moved and oriented to accommodate most utilities, footings, and other obstacles. Integration with utilities is by no means a barrier to using Silva Cells! Silva Cells are designed to be completely structurally independent, meaning it is not necessary for them to be in… More
Water pollution is a serious problem worldwide, whether in rivers and lakes or massive oceans. After the famous Cuyahoga River fire of 1969, environmental regulations were put into place in the U.S. which have helped curb the amount of pollutants we put into our water and reversed some, but not all, of the problems stemming… More

Those who seek the heavens must drive far outside of urban centers and away from light-lined interstates in order to truly see the night sky, and even then, the effects of light pollution cannot be completely escaped. Light from our streetlights and buildings travels farther… More

Our cities and neighborhoods are designed around how cars travel though them, and pedestrians are secondary – if a pedestrian can safely cross traffic, the area is deemed a success. It has long been said that if you plan cities for cars and traffic, you will get cars and… More
After months of design, calculations, and careful planning, construction is starting on your next project. You have spent hours selecting which tree varieties to use, where to place them, and how they will be maintained. Perhaps you have even invested extra time and resources to make sure those trees will have ample soil and water… More
The sounds of the city are adored by some as a source of energy and excitement – the hustle and bustle of people crowding the sidewalks accented by cars and buses whooshing past.
