The Tree Faller’s Manual is an essential handbook for forest operators and others who need to fell trees manually using a hand-held chainsaw. This manual builds on the information provided by the Chainsaw Operator’s Manual. Tree felling is a high risk activity. Many fatalities and serious injuries have occurred as a result of being struck by falling trees, dislodged tree limbs or other dangers in the area. Most of these accidents are caused by using unsafe felling techniques and not following safe work procedures. This manual will guide the faller to safer work techniques. The manual is based on the national competency standards for the forest and forest products industry where tree-felling is covered using three categories: basic, intermediate and advanced. Basic tree felling applies to trees that are relatively small, with a single stem and no defects. Intermediate tree felling covers trees with single or multiple stems, limited defects, and lean and weight distribution that can be adapted to felling direction. Advanced tree felling applies to larger and more complex trees and includes trees deemed to be more hazardous. Workplace safety, risk assessment and site preparation are included along with the theory, techniques and tools for each of the tree-felling categories.
“With the twinned calamities of climate change and mass extinction weighing heavier and heavier on my nature-besotted soul, here were concrete, affordable actions that I could take, that anyone could take, to help our wild neighbors thrive in the built human environment. And it all starts with nothing more than a seed. Bringing Nature Home is a miracle: a book that summons butterflies." —Margaret Renkl, The Washington Post As development and habitat destruction accelerate, there are increasing pressures on wildlife populations. In his groundbreaking book Bringing Nature Home, Douglas W. Tallamy reveals the unbreakable link between native plant species and native wildlife—native insects cannot, or will not, eat alien plants. When native plants disappear, the insects disappear, impoverishing the food source for birds and other animals. Luckily, there is an important and simple step we can all take to help reverse this alarming trend: everyone with access to a patch of earth can make a significant contribution toward sustaining biodiversity by simply choosing native plants. By acting on Douglas Tallamy's practical and achievable recommendations, we can all make a difference.
The Rapid Visual Screening (RVS) handbook can be used by trained personnel to identify, inventory, and screen buildings that are potentially seismically vulnerable. The RVS procedure comprises a method and several forms that help users to quickly identify, inventory, and score buildings according to their risk of collapse if hit by major earthquakes. The RVS handbook describes how to identify the structural type and key weakness characteristics, how to complete the screening forms, and how to manage a successful RVS program.
