Spacing Guidebook

This guidebook is intended to assist forestry practitioners in British Columbia to meet the requirements of the provincial Forest Practices Code with respect to spacing, or the cutting of undesirable trees within a young stand to reduce competition among the residual trees for water, nutrients, and sunlight. Chapters of the guidebook cover the regulations regarding spacing, the maximum density required by the silviculture prescription, biological criteria and operational considerations for including spacing in stand management prescriptions, fire protection, maintenance of stand-level biodiversity, considerations for post-treatment densities, manual and mechanized methods of spacing, selection of crop trees, monitoring, and reporting. The appendices include stand selection guidelines for use in stand management prescriptions.

Provides practical information for would-be space tourists, describing different types of flights and covering flight training, the launch, emergencies, and such aspects as sleeping in weightless environments and using the vacuum toilet --

Beloved science commentator Bob McDonald takes us on a tour of our galaxy, unraveling the mysteries of the universe and helping us navigate our place among the stars. How big is our galaxy? Is there life on those distant planets? Are we really made of star dust? And where do stars even come from? In An Earthling’s Guide to Outer Space, we finally have the answers to all those questions and more. With clarity, wisdom, and a great deal of enthusiasm, McDonald explores the curiosities of the big blue planet we call home as well as our galactic neighbours—from Martian caves to storm clouds on Jupiter to the nebulae at the far end of the universe. So if you’re pondering how to become an astronaut, or what dark matter really is, or how an asteroid wiped out the dinosaurs, look no further. Through a captivating mix of stories, experiments, and illustrations, McDonald walks us through space exploration past and present, and reveals what we can look forward to in the future. An Earthling’s Guide to Outer Space is sure to satisfy science readers of all ages, and to remind us earthbound terrestrials just how special our place in the universe truly is.

Anxiety disorders and OCD are the most common mental health problems of childhood and adolescence. This book provides a complete, step-by-step program for parents looking to alleviate their children's anxiety by changing the way they themselves respond to their children's symptoms.

For everyone who’s curious about what’s new under (and over and around) the stars. Douglas Adams famously pronounced in The Hitchhiker’s Guide to the Galaxy that the answer to life, the universe, and everything was 42. Quirks & Quarks, whose approach to science owes almost as much to Adams as it does to Newton or Einstein or Hawking, have flipped that notion through a gap in the space-time continuum (or something like that) and come up with answers to the 42 essential questions about space. Much about the universe is very hard for most of us to grasp, and if anyone can explain these mind-bending aspects of the heavens above, it’s the Quirks & Quarks producers, who have been bringing Canadians understandable science, with trademark humour, for more than thirty years. In their Guide to Space, they answer such pressing questions as Where does space begin? Why is most of the universe missing? Is there intelligent life in the universe? And the real puzzler: What came before the Big Bang? They also answer questions we wish we’d thought to ask, such as Can you surf a gravity wave? and Why is the universe’s temperature on my TV? There are answers as well to far more practical questions, like What happens when you fall into a black hole? and How will the universe end? The answers, which have been vetted by a team of astronomers, are witty, authoritative, in-depth, accurate, up-to-date astronomically, and, of course, quirky.

This guidebook has been prepared to help forest resource managers plan, prescribe, and implement sound forest practices that comply with the British Columbia Forest Practices Code. The information provided is to help users exercise their professional judgment in developing site-specific management strategies and prescriptions to accommodate resource management objectives in the Vancouver Forest Region.
