Book Description
Defective trees are potential hazards to people and property in recreation areas. Most reported tree failures within recreation sites in the Rocky Mountain Region occur in lodgepole pine. Defective root systems account for the greatest percentage of failures. External indicators of defects are used to identify trees that may fail. Some tree species, particularly aspen, are highly susceptible to visitor damage; managers should restrict recreational development in such forest types. Old growth spruce-fir stands should also be avoided for developed sites. Systematic, annual, documented inspections of trees in recreation sites and corrective action are recommended to reduce hazards to the public.

Book Description
Dendrogeomorphology Beginnings and Futures: A Personal Reminiscence My early forays into dendrogeomorphology occurred long before I even knew what that word meant. I was working as a young geoscientist in the 1960s and early 1970s on a problem with slope movements and deformed vegetation. At the same time, unknown to me, Jouko Alestalo in Finland was doing something similar. Both of us had seen that trees which produced annual growth rings were reacting to g- morphic processes resulting in changes in their internal and external growth p- terns. Dendroclimatology was an already well established field, but the reactions of trees to other environmental processes were far less well understood in the 1960s. It was Alestalo (1971) who first used the term, dendrogeomorphology. In the early 1970s, I could see that active slope-movement processes were affecting the growth of trees in diverse ways at certain localities. I wanted to learn more about those processes and try to extract a long-term chronology of movement from the highly diverse ring patterns.

Book Description
In this eloquent plea for compassion and respect for all species, journalist and gardener Nancy Lawson describes why and how to welcome wildlife to our backyards. Through engaging anecdotes and inspired advice, profiles of home gardeners throughout the country, and interviews with scientists and horticulturalists, Lawson applies the broader lessons of ecology to our own outdoor spaces. Detailed chapters address planting for wildlife by choosing native species; providing habitats that shelter baby animals, as well as birds, bees, and butterflies; creating safe zones in the garden; cohabiting with creatures often regarded as pests; letting nature be your garden designer; and encouraging natural processes and evolution in the garden. The Humane Gardener fills a unique niche in describing simple principles for both attracting wildlife and peacefully resolving conflicts with all the creatures that share our world.
