The American National Standards Institute (ANSI) and Tree Care Industry Association (TCIA) have placed a call for public review of a revision draft for the current ANSI A300 (Part 4)-2008, the standard for lighting protection systems in trees. This is the intended final public review draft for this revision and will be open for comments through June 24, 2013. The A300 Part 4 standard addresses the following items:
May's TCI Magazine cover story, Managing Drought Stress on Urban Trees, by Brandon M. Gallagher-Watson takes a look at how drought is a condition that can be managed and the stress on trees can be reduced.
Back in 2011, during Texas’ worst drought on record, Bastrop State Park was nearly destroyed by wildfires caused by 30 mph wind gusts that blew broken tree limbs into power lines. The fires killed two people, destroyed around 1,700 homes, and burned nearly 6,000 acres of the park.
On Friday, April 12, Petzl was informed of an accidental fall in a training center in Germany. This fall was related to a failure of the rope end attachment hole of the Petzl ZIGZAG mechanical Prusik. Petzl has since been informed of another identical failure.

As part of a national Arbor Day Foundation program called "Energy Saving Trees," Atlantic City Electric in New Jersey is offering 2,000 free trees to customers. The idea is that planting them strategically near houses and businesses can help reduce energy bills.
An online tool developed by the foundation and TCIA member company Davey Institute uses Forest Service research to calculate the benefits of planting trees, including cleaner air and improved storm-water management.
