    How Wind Forces Cause Damage. Wind forces can break the building's load path or punch a hole in the building envelope. Sometimes the actual force of high winds can cause a door or window to break open. Other times nearby debris can be picked up in the wind and projected against the building envelope.   Fig. 2a–c shows the influence of bark beetle mortality on various fuels characteristics during the period between bark beetle refer to this period of time as the bark beetle rotation for Engelmann spruce, Douglas-fir and lodgepole pine. Each of the seven graphs were derived from fuels data collected in stands with endemic, epidemic and post-epidemic populations of bark beetles.

    Building wind damage assessment & damage repair or restoration procedures. This article series provides residential & light construction building wind damage assessment procedures for buildings following disasters such as from a hurricane, cyclone, tornado, or other wind damage. We discuss safe building entry procedures, setting the priority for repairs, and we give more detailed building. wind speed increases, trees are more likely to suffer damage (i.e. uproot, break, or lean), resulting in greater urban forest loss, as the graph shows. However, it is important to point out that in addition to wind intensity and speed, other factors influence urban forest damage during hurricanes.

Description: Damage to timber surrounding clearcuttings and in one light selection cutting in mixed white fir-red fir stands was monitored for 6 years in northeastern California.

Balsam fir stands represent 62% of the total windthrown area in the Charlevoix region. For wind speeds between 28–37 km h −1, pure balsam fir stands were more heavily damaged in comparison with spruce-fir stands (black spruce: Picea mariana (Mill.) B.S.P.) (p=) ().For winds reaching 37–46 km h −1, years-old pure balsam fir stands were more damaged than fir-birch stands.

Plantation Silviculture in Europe provides an up-to-date, succinct, and comprehensive overview of current European plantation forestry practices. Recognising that plantation silviculture today is no longer largely a question of how to grow large-scale industrial plantations, the authors have included chapters describing other, more diverse reasons for establishing trees.

Damage from wind and other causes in the mixed white fir-red fir stands adjacent to clearcuttings. USDA Forest Service Research Paper PSW. GENERAL BOTANICAL CHARACTERISTICS: White fir is a large, native, coniferous tree. Mature white fir trees in the central Sierra Nevada are to feet ( m) tall, and 40 to 80 inches ( m) dbh, but may grow larger [,].Rocky mountain white fir rarely exceeds feet (38 m) tall or 3 feet ( m) in diameter [].Bark on young trunks is smooth, gray and blistered with resin.

Stem or branch failure is a recurrent problem in silviculture and arboriculture. The risk of rupture varies with species in relation to the inherent mechanical properties of the species and the presence of defects.

In general, calculations of critical loads for breakage are based on mechanical properties determined from defect-free samples and adjustment factors that try to scale up to full. The literature on the effects of catastrophic wind disturbance (windstorms, gales, cyclones, hurricanes, tornadoes) on forest vegetation is reviewed to examine factors controlling the severity of damage and the dynamics of recovery.

Wind damage has been quantified in a variety of ways that lead to differing conclusions regarding severity of disturbance.

Preventing Damage from Wind. Plants with a constant stream of wind blowing over them may develop wilted leaves and brown edges from desiccation. The plants may need water, but chances are good that the wind is simply drying the leaves faster than the roots can pull water from the soil.

Median point fire return intervals were shortest in lower montane mixed conifer and Jeffrey pinewhite fir stands ( y) and upper montane red firwhite fir stands ( y), intermediate in.

At lower elevations red fir habitats intergrade with white fir-dominated mixed conifer stands on drier sites and with lodgepole pine-mountain meadow stands on moist sites.

In stands with fir presence, practices which cause abrupt environmental changes such as clear-cutting negatively affect silver fir (Eichenseer ) as it was the case in the past in regions such.in mixed stands with white fir and incense cedar at lower ele- vations (and Sierra juniper in the north), and with red fir and lodgepole pine at higher elevations (Potter ).Interior Douglas-fir is a prevalent forest type throughout the central Rocky Mountains.

Past management actions, specifically fire suppression, have led to an expansion of this forest type. Although Douglas-fir forests cover a broad geographic range, few studies have described the interactive effects of various disturbance agents on forest health conditions.
