MODELING LANDSCAPES FOR VINEYARD SITE SUITABILITY IN A MARGINAL CLIMATE

O. Shaposhnikova, A. DeGaetano, A.N. Lakso
Some winegrape-growing regions are on the cold margins of grape production. In these cases, the landscape is important to the patterns of damaging coldest temperatures, as well as to growing season conditions. Vineyard site selection is a priority in New York State and Ukraine to optimize current sites and identify acceptable new vineyard sites in regions with many unsuitably cold sites. Important environmental factors (climate, soil, topography, etc.) that influence grapevine winter injury and survival, development, and fruit quality, were integrated to define micro zones for quality wine production in Ukraine, based on landscape and ecosystem studies. For New York State, an online GIS-based vineyard site evaluation system was created (http://www.nyvineyardsite.org) to provide basic site information for site decision support. It includes information on soil suitability data, climatic and topography parameters. Site suitability maps for groups of grape cultivars and species are being developed based on varying climate and landscape requirements. Additionally, relationships of topography to temperature patterns in vineyards of the Finger Lakes region were modeled to estimate the warming “lake effect” that is noted in the winter. A temperature database was collected on the local vineyard scale with temperature sensors. The system represents a valuable tool that helps vine growers of New York State in the decision-making process choosing a vineyard site.
