Like John Muir, David Pitt-Brooke stepped out for a walk one morning—a long walk of a thousand kilometres or more through the arid valleys of southern interior British Columbia. He went in search of beauty and lost grace in a landscape that has seen decades of development and upheaval. In Crossing Home Ground he reports back, providing a day-by-day account of his journey’s experiences, from the practical challenges—dealing with blisters, rain and dehydration—to sublime moments of discovery and reconnection with the natural world. Through the course of this journey, Pitt-Brooke’s encounters with the natural world generate starting points for reflections on larger issues: the delicat...
With growing numbers of people turning to birdwatching as their favourite outdoor activity, this delightful book will be welcome. Unlike the typical guidebook, this beautifully illustrated work brings readers the birding experience-the thrill of spotting a particular bird for the first time, the wonder of witnessing the easy power of a gyrfalcon's flight, the pleasure of watching the dramatic choreography of a flock of wheeling shorebirds. Naturalist and veteran birder Bruce Whittington takes the reader through a year with birds. Each month offers descriptive information about several birds, along with interesting bits of bird lore, including the incredible story of long-range migrations, how birds fly, the plumage changes they undergo, and the life stories of early ornithologists. Read in its entirety or savoured story by story as the months on the kitchen calendar go by, this wonderful book will edify and please all who appreciate the beauty and song of our "feathered friends."
Whitebark pine is a critical component of subalpine ecosystems in western North America, where it contributes to biodiversity and ecosystem function and in some communities is considered a keystone species. Whitebark pine is undergoing rangewide population declines attributed to the combined effects of mountain pine beetle, white pine blister rust, and fire suppression. The restoration and maintenance of whitebark pine populations require an understanding of all aspects of seed fate. In this paper, we review the literature on seed dispersal in whitebark pine. Clark's nutcracker, pine squirrels, and scatter-hoarding rodents are all known to influence whitebark pine seed fate and ultimately affect the ability of whitebark pine populations to regenerate. We also provide a general overview of the natural histories of the most influential species involved with whitebark pine seed fate: Clark's nutcracker and the pine squirrel.
Birdwatching is one of America's most popular activities, but many field guides are so comprehensive or advanced that they intimidate novice birders. Covering the region north of the U.S. border, south of Prince George, east of Manning Park and west into the Rockies, Birds of Interior BC and the Rockies is for beginning and intermediate birders who wish to identify the birds they regularly spot in this area. However, the book will also appeal to more experienced local and visiting birders who want to learn more about the behavior, habitat and seasonal occurrence of local birds. Packed with useful information, this handy, portable guide tells you how to identify local birds, find out where they live and what they eat, how to attract birds to your yard and how to select a pair of binoculars. Identification is made easy with more than 400 sharp, full-color photos illustrating over 200 species of birds, in the plumage most likely seen in the region and color-coded by species. There's even a checklist to record your sightings.
