Abstract: Large timber availability after storms can lead to a drop in timber prices that can impact local markets. The Vaia storm, which occurred in Northeastern Italy at the end of October 2018, felled large volumes of timber, particularly spruce. To estimate the loss in volume and value connected to Vaia, data of roundwood sales from four local markets (Province of Trento, Province of Bolzano, Veneto Region and Friuli Venezia Giulia Region) were collected before and after Vaia, as well as reports on the status of salvage operations. The results confirm that Vaia had a strong impact on Northeastern Italy. A large area of the forest was hit and massive volumes of wood were affected. The analysis of prices showed a negative trend in the post-Vaia period due to an increase in volume per sale, especially for stumpage sales. It also highlighted the difficulties of storing the salvaged wood and the consequent fast saturation of the market. Although it was not possible to assess long-term effects on the four local markets, the presence and use of local e-commerce platforms proved useful in making roundwood sales more organized and efficient.

Forests 2021, 12, 414 3 of 19 Motta et al. [2] explored the main factors explaining the damage provoked by Vaia and compared it to four other major storm events across Europe, showing that site and climatic conditions played a major role in this case: for example, the pure spruce stands of the Fiemme Valley in Trentino Alto Adige are historically susceptible to wind damage because of microclimatic and topographic conditions, and forest composition and structure. A new database of wind disturbances in European forests named FORWIND, also including data on Vaia, was published at the end of 2019 [10], with information on more than 80 thousand spatially delineated areas disturbed by wind in the period 2000–2018. This database enables comparisons amongst storm events across Europe. Windthrow events are typically followed by a fall in roundwood prices, with con- nected effects on procurement that can last months or even years [4,11]. Changes in price may depend on (1) the amount of windthrow timber; (2) the possibility to increase exports and reduce imports of roundwood; (3) the possibility to store roundwood; (4) the extent of utilization capacity in the local forest-based industries; (5) the price elasticity of demand and (6) the quality of salvage harvests [11]. Gardiner et al. [4], Schwarzbauer et al. [11] and González-Gomez et al. [12] studied price trends in spruce-dominated Central European markets, showing that the drop in price fluctuates in intensity and duration. Toth et al. [13] showed that a larger quantity of calamity logging available on the market in respect to ordinary times affected the timber price drop in the Czech Republic. Nieuwenhuis et al. [14] documented the same drop in Ireland following a storm in 1997. Eriksson et al.
