“…Strawberry yield and quality can be affected by day length, temperature, soil characteristics, altitude, latitude, cultivation system and management practices (Kruger et al, 2004) and the variation in strawberry yield among four states can be attributed to these factors. One of the most important factors was the climate (Palencia et al, 2013) which was totally different among these four states. California's unique climate (moderate temperature year round) is a perfect condition for growing strawberry which result in high yield (1.25 million tons strawberry production in 2014 (90% of the U.S. strawberry production) (USDA, 2015)).…”

The goal of this study was to develop a cradle to farm gate life cycle inventory and assess the environmental impacts of strawberry production in four major strawberry producing states of the United States: California, Florida, North Carolina and Oregon, representing 99% of the United States strawberry production. Life cycle environmental impacts depend strongly on geographic location and production practices. Data for California and North Carolina strawberry production were collected in collaboration with agricultural economists from those states using the "LCA Extended Enterprise Budget" Excel sheet (version 4.11). Data for Florida strawberry production were collected from the state's existing enterprise budget (a detailed accounting of production costs and returns which estimates profitability of an enterprise). Data related to Oregon strawberry production were obtained through interviews with strawberry producers. OpenLCA software was used to conduct life cycle assessment for strawberry production. Missing unit processes for production of agricultural machinery, pesticides, fertilizers and materials were modeled based on existing literature. In order to better assess the sustainability of strawberry production, three metrics encompassing nitrogen productivity, phosphorous productivity and fossil energy productivity were introduced. Global warming potential for California, Florida, North Carolina and Oregon strawberry production was estimated to be 1.75, 2.50, 5.48 and 2.21 kg CO 2-eq per 1 kg of strawberry, respectively. The difference between LCA results was due to variation in yield and management practices which depend on geographic location. Plastics, fuels and fertilizers were the inputs with the highest contribution to environmental impact categories. California strawberry production scored the highest on three sustainability metrics mainly due to having the highest strawberry yield.

“…Weather influence on strawberry has been documented in various studies. For instance, [3] examined strawberry yield efficiency and its correlation with temperature and solar radiation and found strawberry yield was significantly correlated with solar radiation. There are various other studies that showed the importance of solar radiation in strawberry growth and development overall [4][5][6].…”

California state is among the leading producers of strawberries in the world. The value of the California strawberry crop is approximately $2.6 billion, which makes it one of the most valuable fruit crops for the state and nation’s economy. California’s weather provides ideal conditions for strawberry production and changes in weather pattern could have a significant impact on strawberry fruit production. Evaluating relationships between meteorological parameters and strawberry yield can provide valuable information and early indications of yield forecasts that growers can utilize to their advantage. Objectives of this paper were to evaluate correlations of meteorological parameters on strawberry yield for Santa Maria region and to develop meteorology based empirical yield forecasting models for strawberries. Results showed significant correlation between meteorological parameters and strawberry yield and provided a basis for yield forecasting with lead time. Results from empirical models showed that cross-validated yields were closely associated with observed yield with lead time of 2 to 5 months. Overall, this study showed great potential in developing meteorology based yield forecast using principal components. This study only looked at meteorology based yield forecasts. Skills of these models can be further improved by adding physiological parameters of strawberry to existing models for strawberry.

Citation: Pollock, S. Z., S. E. Nielsen, and C. C. . A railway increases the abundance and accelerates the phenology of bear-attracting plants in a forested, mountain park. Ecosphere 8(10):e01985. 10. 1002/ecs2.1985 Abstract. Vegetation enhancement along railways has not been well studied, despite high rates of mortality from train strikes across numerous species, including sensitive populations in protected areas. This situation describes grizzly bears (Ursus arctos) in the mountain parks of Canada, where train strikes have become the leading source of known mortality. We hypothesized that attraction by bears to railways occurs partly because of increases in the richness, diversity, cover, and maturation rate of plants consumed by bears relative to adjacent forest and that this effect may increase with elevation. We quantified and compared responses in plants used by bears to the railway (ballast), forest edge, and within adjacent forest for two growing seasons (May-October) at 19 locations spanning an elevational gradient in Banff and Yoho National Parks in the Canadian Rocky Mountains. Overall, richness, diversity, and total cover of plants consumed by bears were greatest at the forest edge. On the forest edge or ballast, flowering rates of some species were over three times higher and fruit occurrence was up to five times higher than 50 m into the adjacent forest. Enhancement of berry productivity along rail edges increased with elevation. Buffaloberry (Shepherdia canadensis), an important regional pre-hibernation resource, had more fruit, faster ripening, and higher sugar content for shrubs located within 15 m of the rail than within surrounding interior forest. Our results demonstrate that railway edges can increase the quantity and quality of palatable vegetation resources of both native and introduced species, potentially increasing strike risk for bears and other wildlife. Potential mitigation of this risk could include removal of attractants along the rail, particularly at locations where other factors increase the risk of collisions, and creation of forest openings, either through natural processes or through forest modification that would provide forage in less risky habitats.
