Down Dead Wood

Abstract Fallen or down dead wood is a key element in healthy forest ecosystems. Although the amount of down wood and shrubs can provide critical information to forest resource managers for assessing fire fuel build up, data on biomass of down woody materials (DWM) are not readily accessible using existing databases. We summarized data collected by the USDA Forest Service's Forest Inventory and Analysis (FIA) program into biomass for mixed-oak forest types in Kentucky, Virginia, Tennessee, and North Carolina to obtain a baseline average for Appalachian mixed-oak forests. We sampled a subset of 76 plots from 16 oak forest types and computed biomass for each DWM component, using slightly different equations for each. Biomass of DWM components was summarized using simple statistics. The mean of all DWM components combined was 32 Mg/ha, and the median was 29 Mg/ha. Over half the mean DWM was duff and litter (18 Mg/ha combined); coarse woody material (CWM) was less than 15% of mean DWM; and fine woody material (FWM) (7 Mg/ha) was almost twice CWM. The range of mass for individual components was quite large. These estimates compare favorably to those found in studies for other forest types. South. J. Appl. For. 28(2):113–117.

Trends in windthrow management during the last 50 years in Lower Valais (essay) A review on the measures taken in forests hit by storms during the last 50 years reveals the mind-set behind the evolution of management operations. In the 1960s, to remove all dead wood in a stand was perfectly normal due to timber prices. Between 1984 and 1990, vast sums of money were pumped into the improvement of forest structures facing the threat of a general forest dieback. As a consequence, only few of the windthrow areas caused by storm Vivian remained with no intervention. Vivian also marked the beginning of manifold research activities and practical terrain examination in windthrow gaps. Conclusions of this first research phase resulted in a critical assessment of the windthrow areas caused by Lothar in 1999, considering different goals than systematic removal of damage wood and the prevention of bark beetle outbreaks. Since the 1990s, retaining timber after windthrow has been lively discussed, as well as the maintenance of the protection function against natural hazards and opportunities for biodiversity. Several handbooks were developed and successfully used for the planning and defining of top priority measures in damaged forests that resulted from disturbances in 2011 and 2012 in Lower Valais. These recent disturbances together with the certainty that storms will recur led to the formation of a task force in the canton Valais, aiming to organize both logistics and funds, as well as to define management priorities regarding a next hazard.

Responsibility for forest-linked dangers: examples from legal practice According to the Forest Policy 2020 of the Federal Council the share of old and dead wood should increase in Swiss forests. On the one hand, this is connected to positive ecological effects but on the other, to dangers, responsibilities and liability risks. Recent court and administrative decisions relating to accidents due to typical forest hazards such as falling trees and branches illustrate the legal situation for forest owners and enterprises as well as for forestry professionals. In the wooded environment near buildings and equipment there are obligations for the safety of traffic and passers-by. However, these obligations are limited by the reasonableness of protective measures and the personal responsibility of forest users. In this paper, the liability issue is illustrated by three legal case studies. The cases are assessed by the author, and the essential legal basis for liability is briefly summarized.

The Cost

Translocation of dead wood is a novel method for ecological compensation and restoration that could, potentially, provide a new important tool for biodiversity conservation. With this method, substrates that normally have long delivery times are instantly created in a compensation area, and ideally many of the associated dead wood dwelling organisms are translocated together with the substrates. However, to a large extent, there is a lack of knowledge about the cost efficiency of different methods of ecological compensation. Therefore, the costs for different parts of a translocation process and its dependency on some influencing factors were studied. The observed cost was 465 SEK per translocated log for the actual compensation measure, with an additional 349 SEK/log for work to enable evaluation of the translocation’s ecological results. Based on time studies, models were developed to predict required work time and costs for different transportation distances and load sizes. Those models indicated that short extraction and insertion distances for logs should be prioritized over road transportation distances to minimize costs. They also highlighted a trade-off between costs and time until a given ecological value is reached in the compensation area. The methodology used can contribute to more cost-efficient operations and, by doing so, increase the use of ecological compensation and the benefits from a given input.
