Structure and function of western red cedar and western hemlock forests on northern Vancouver Island
… differences may have been due to: (i) regular windthrow in the HA type, (ii) a greater accumulation of forest floor organic matter in the CH type, which may lead to detrimental changes in soil physical properties; or (iii) differences in foliar and woody litter quality of the dominant …

Modeling gap dynamics, succession, and disturbance regimes of mangrove forests
… gaps remained as “green islands” within windthrow sites in the plantation due to their low stature and provided seeds for surrounding disturbed areas thereby accelerating their recolonization. The results of the simulation analysis of a theoretical landscape showed that in the simulated …

Vegetation community development eight years after harvesting in small streams buffers at the Malcolm Knapp Research Forest
… treatments, up to 15% overstory trees were windthrown in the first 2 years after harvest producing large canopy gaps. Consequently, the understory development in the 10m and 30m buffers is more like that in the 1868 and old-growth stands than in the controls, but these treatments still lack …

Climate change vulnerability assessments in the regional context
… an exemplary sectoral study was carried out on windthrow impacts in forests to provide an absolute quantification of the present and future impact. This is achieved by formulating an empirical relation between the forest characteristics and damage based on data from a past storm event. The …

Effect of fire and wind-throw on a forest area
This study is a quantitative analysis of the effect of fire and wind-throw on a spruce-fir-northern hardwoods forest on Peaks Island, Casco Bay, Maine. Six years after the burn, data for the effect of fire on approximately 170 acres of this forest type, were collected and categorized. The …

Biomass and Nutrient Studies of Selected Tree Species of Natural and Plantation Forests: Implications for a Sustainable Management of the Munessa-Shashemene Forest, Ethiopia
… has a shallow root and is more susceptible to windthrow compared to E. globulus. With the exception of E. globulus, the dry season live fine root (LFR) biomass was higher for all trees studied. The seasonal variation in the fine root biomass was attributed to the changes in soil moisture of the …

Ökonomische Bedeutung und Management von Naturrisiken im Wald : theoretische Grundlagen und empirische Analysen nach dem Sturm Lothar in der Schweiz
In den 1990er Jahren haben schwere Stürme in West- und Mitteleuropa deren hohes Schadpotential verdeutlicht. In dieser Arbeit wurden die ökonomischen Auswirkungen von Sturmschäden, die Sturmbewältigung und das Risikomanagement mit einem Fokus auf Versicherungslösungen in fünf Studien am Beispiel …
