Background
The department of Forest Economics of
Baden-Wuerttemberg's Forest Research Institute (FVA) developed the "Storm
Handbook – Coping with storm damaged timber" for the federal states of
Baden-Wuerttemberg and Rheinland-Pfalz on behalf of the Ministry for Food and
Rural Areas Baden Wuerttemberg and in collaboration with the Forest Research
Institute Rheinland-Pfalz.
While clearing up the damage caused by storm "Lothar"
(1999) it became clear that, despite a purposeful and coordinated action for
coping with the damage, a practical handbook for on-site staff is needed to
handle storm damage which might occur in the future.
So far, a practical guide for handling extreme damage
situations for locally affected staff and forest owners is missing. This
handbook deals primarily with technical instructions, gives suggestions and
proposes solutions as a direct aid for coping with future storms.
Objectives
The aim of the project was to develop a
practical and technically oriented handbook on how to cope with storm damaged
forests. The main contents being basic and fundamental information as well as
lastingly valid instructions to fill information gaps on how to deal with
suddenly occurring calamities.
The collection of instructions, checklists and
leaflets encompasses the whole process of coping with storm damaged timber and
provides basic information. The handbook therefore creates a basic standard of
knowledge, providing staff with a compendium for future storm calamities,
enabling them to handle the damage in a well equipped, calm and efficient
manner.

1. First Measures and Survey of
Damages
|
|
|
|
Survey of Damages after Storm Events
|
 |
|
Exact information on the extent of storm damage is important to forestry offices/ forest authorities, forest districts as well as for forest administration management planning, organising and coping with the storm's aftermath.
|
|
2. Strategies and Personnel Management
|
Foundation of a Solidarity Community
|
 |
|
The foundation of a solidarity community offers key benefits when coping with storm damages. The community of Gengenbach exemplified this after storm "Lothar".
|
|
|
|
The Forest Damage Compensation Law
|
 |
|
If national impacts on the timber market due to a storm catastrophe are expected, it's possible to reduce the regular cut in other non affected federal states by the Forest Damage Compensation Law.
|
|
|
|
|
|
Strategies for storm damage management
|
 |
|
How to find the best strategy for storm damage management? Several factors are to be considered. A reasonable way is to have a common strategy for all affected owners.
|
|
|
Personnel Management at Salvage Logging
|
|
|
Without a doubt there will be an extraordinary high work load for all personnel after storm catastrophes. Appropriate personnel measures are necessary to support personnel motivation.
|
|
|
|
3. Salvage Logging and Work
Safety
|
Harvesting Methods for Windthrown Timber
|
 |
|
Which harvesting method is most suitable when coping with storm damages? Depending on conditions and availability of machines different combinations are possible.
|
|
|
|
Storm Damage - Work Safety
|
 |
|
Dangerous situations - at the beginning of logging due to safe practices being underestimated or overlooked and later on as work becomes routine and is treated light-heartedly.
|
|
|
|
|
|
Salvage Logging of Storm Damaged Timber
|
 |
|
Safety training, organising the supporting machines, instruction of contractors, maintaining quality standards … Many things have to be taken into consideration for a safe and clean salvage logging.
|
|
4. Timber Storage
|
Storage Methods after Calamities
|
|
|
Log-conservation is an important issue after storm events. Due to the situation, there are different methods of log conservation.
|
|
|
|
|
|
|
|
Timber Storage - Storage Over Bark
|
 |
|
The simplest way to store storm-damaged timber is the storage over bark alongside forest roads - if the period of time between processing and transport to the customer is known.
|
|
4.1 Wet Storage
|
|
|
|
Wet Storage – Winter Operation
|
 |
|
This article shows how the irrigation system needs to be handled in winter to prevent the timber and the system itself from damage.
|
|
5. Forest Protection
|
Insecticides
|
|
|
Instructions for professional application of insecticides.
|
|
|
|
|
|
|
|
Integrated Forest Protection
|
 |
|
Forest protection problems – mostly bark beetle calamities – mainly follow storm calamities. Integrated Forest Protection can be an important instrument for preventive measures.
|
|
|
Bark Boring Insects
|
 |
|
The most effective way of reducing bark beetle damage to conifers is "clean" forest practise.
|
|
|
|
Wood Boring Insects
|
 |
|
After storm damages there is often a proliferation of wood boring species as well as bark boring species. They can do considerable economical damage.
|
|
6. Timber Transportation
|
Transportation by Truck
|
|
|
Not only to avoid transportation shortages during catastrophes but also in normal times, truck transport systems with containers or trailers are an interesting alternative to common timber trucks.
|
|
|
|
|
Timber Haulage by Railway
|
 |
|
For long distance transportation of timber after storm events the railway is a cost efficient alternative. Thereby additionally capacities for short distance transportation are made available. The article shows what has to be taken into consideration when organising transportation by railway.
|
|
|
|
Timber Haulage by Ship
|
 |
|
For the first time after the "Lothar" stormlarge amounts of timber from Baden-Wuerttemberg was shipped to customers. The immense organisational effort demands careful planning and coordination.
|
|
7. Regeneration and
Afforestation
|
Regeneration and Afforestation of Storm Damaged Areas
|
|
|
Post storm the question arises: How to reafforest a side adapted stand? Through the assessment of the site and the existing and expected natural regeneration, it is possible to estimate the potential of the area to regenerate naturally.
|
|
|
|
8. Subsidies and Public Relations
|
Public Relations after Storm Events
|
 |
|
Due to storm damage coverage, the forest and forestry receives a broad media response ("Only bad news is good news"). Ongoing media coverage of well chosen topics helps the public build a positive image of forest enterprises.
