Development of storm resistant landscapes (STORMRISK)

Development of STORM resistant landscapes through regional co-operation, adapted management and RISK communication


Storm damage in southern Sweden, January 2005The countries situated around the North Sea have experienced forest wind damage throughout history. Severe storms in recent years have caused large scale disruption not just to forest industries, but also to the infrastructures of these countries, and climate change is expected to increase the frequency of these extreme events in the North Sea Region. Experiences and expertise on how to reduce windthrow in forest landscapes have developed differently in each country.

The aim of the STORMRISK project was to integrate and make accessible the knowledge and experience developed over decades to end-users in the North Sea Region.

Research objectives

There were four different activities within the project:

Future aims and ecological conditions for the forests and landscapes in the North Sea Region

Knowledge of past storm damage in the North Sea Region will be collected and various scenarios for the future climate in the Region will be examined. Available information on landowner and management aims as well as expected future trends were collected and disseminated. Two pilot study landscapes in storm damaged areas in Sweden were conducted in cooperation with land owners and other stakeholders.

Wind damage - general planning models and risk communication

The wind damage models, ForestGALES and Winda, were used to calculate the probability of stand scale wind damage in the pilot study areas. Information from running the models provided decision support to land owners.

Preventive management methods to reduce the risk of wind damage to natural and cultural landscapes

In order to give landowners, planners and managers options on how to create and manage their future landscapes, information on wind damage risk and alternative management methods was made easily accessible. Existing knowledge and information about forest wind damage, preventive management methods and restoration was gathered and evaluated. The information collected was evaluated by an expert group and transformed into a toolbox available via the project website.

Establishment of new sustainable forests and landscapes

Forest owners and managers were given advice and knowledge to assist them in responding to current and future challenges presented by the wind climate in the North Sea Region. The STORMRISK project provided a source of inspiration by demonstrating experiments on how to create sustainable forests and landscapes. This in combination with publications, excursions, and a web based "toolbox" based on all the project activities provided up-to-date information adapted to practical forestry.

Funders and partners

The STORMRISK project was part funded by the European Regional Development Fund through the Interreg IIIB North Sea Programme.

Forestry Commission policy

Research on windthrow has been identified as a component of the UK Programme on Sustainable Forestry. Paragraph 3.28 states the aim:

"To promote better prediction of the onset of windthrow to optimise the returns from windthrow susceptible sites."

This is consistent with priorities identified by other organisations such as Timber Growers Association (TGA), Home Grown Timber Advisory Committee (HGTAC) and the National Audit Office (NAO).

Forest Research activities in the STORMRISK project

These included release of a web-based version of ForestGALES that can be adapted for use in any part of the North Sea Region where wind data are available, and developing methods to map wind risk to forests at a landscape scale using remote sensing data from air-borne LiDAR.

Further information

The use of LiDAR remote sensing data for forest wind risk management was featured at the Silvilaser Conference in September 2008.

The STORMRISK project started in 2006, and was completed during 2008.
