What opportunities for training and professional development has the project provided?This project has created the opportunity for Michael North (post doctoral fellow) to (1) facilitate a multi-state collaborative research project for the first time, (2) practice communicating research procedures and outcomes to a general audience, (3) expand his experience collecting a new time-series cold hardiness dataset, and (4) further develop his experience analyzing cold hardiness data and writing code to generate process-based mathematical models. How have the results been disseminated to communities of interest?M. North presented a seminar at thePlants and Climate Symposium at Reiman Gardens (Ames, IA) in September 2023. This event was attended by a wide audience demographic, including general public, farmers, Iowa State University students, staff and faculty, and Iowa State University Extension and Outreach staff. Co-PI A. Kovaleski presented a seminartitled "Cold hardiness is a covariant in dormancy assays" at the International Plant Dormancy Symposium in Perth, WA, Australia on 09/2023. This event was attended by scientist, extension professional, and stakeholders. Co-PI A. Kovaleski presented a seminar titled Dormancy non-binary: moving away from the endo-ecodormancy dichotomy (part of workshop: "Fruit and nut tree dormancy and flowering biology in a changing environment") at the American Society for Horticultural Science Annual Conference on 08/2023 in Orlando, FL. This event was attended by scientists, students, extension professional, and stakeholders. Co-PI A. Kovaleski presented a seminar titled "Activity of woody perennials through winter" at the Allen Centennial Garden Winter Presentation Series at the University of Wisconsin Madison, Madison WI on 02/2023. This event was attended by a wide audience demographic, including general public, farmers, students, staff and faculty, and Extension and Outreach staff. What do you plan to do during the next reporting period to accomplish the goals?Obj. 1:We plan expand our compiled dataset by (1) soliciting more requests for preexisting bud cold hardiness datasets, (2) repeating experiments with dormant grapevine canes in the same locations and with the same cultivars approximately monthly in winter of 2024-2025, and (3) expanding future experiments to include both new locations (coordinating with collaborators in Georgia and Ohio) and additional cultivars (considering Vitis vinifera cultivars that are available from 3 or more locations). We will also proceed with model optimization and validation using stepwise iterative methods that generate root mean square error, correlation coefficients, and bias (the predicted minus measured value). These statistics will be produced for all interaction of cultivar, year, and location. Obj. 2:A user interface (UI) for preliminary testing will be completed in Year 2. User experience and user interface (UX/UI) feedback will be collected in the coming year for improvements over the winter. NYUS1 and WIUS1 models will be finalized by June 15, 2024. These are programmed in javascript directly to the web app. NYUS2 is generated from a python-based machine learning algorithm and requires an external API call. This is within project scope but was unexpected and requires additional time for implementation because a separate workflow is required to send station data from NEWA to an external endpoint hosted by NYSIPM in the cloud, which will then return results. Once implemented, however, this will be a useful method for using new ML and AI methods in NEWA risk assessments. Northeast Regional Climate Center also developed an option for users to choose a 'gridded' data point, which will be implemented by June 1. 2024. This means a user can use a physical NEWA location or a 'virtual' location from any location in the continental United States (CONUS). This hybrid approach is the first of its kind on the NEWA platform and work completed for use in this grape cold hardiness risk tool lays the groundwork for future integrations in future models. The user will have a seamless experience when switching between models and data types, however, as the entire process will take 1 or 2 seconds at most. By October 2024, all three models will be fully integrated, allowing the user to select from an extensive list of grape cultivars, each utilizing one of the three models, predetermined by the lead investigators. Obj. 3: We will deliver 2 webinars to introduce stakeholders to the NEWA ColdSnap tool; we will present at 2 grower meetings (NY and WI); we will develop 2 blog posts in the NEWA blog. All these extension activities will target grape growers in the Midwest and Northeastern regions, extension professionals, and scientist.
Impacts What was accomplished under these goals?
Obj. 1. Validate and expand two newly developed bud cold hardiness prediction models through analysis of regionally diverse data collected in: New York, Wisconsin, South Dakota, Minnesota, Michigan, Ohio, Pennsylvania, Iowa, and Quebec. A bud cold hardiness dataset for model optimization and validation was created by compiling multiple preexisting datasets, including datasets from Iowa (3 sites, 33 cultivars, 2 seasons), Michigan (11 sites, 11 cultivars, 2 seasons), Pennsylvania (1 site, 2 cultivars, 2 seasons), Quebec (15 sites, 17 cultivars, 4 seasons), and Wisconsin (1 site, 5 cultivars, 5 seasons). In addition, new bud cold hardiness data was generated by running experiments with dormant grapevine canes from 7 states (IA, MN, 2 locations in NY, PA, SD, TX, 2 locations in WI) including 8 different cultivars (Cabernet Sauvignon, Clarion, Concord, Frontenac, Itasca, Marquette, Petite Pearl, Riesling; see list below for distribution of cultivars received according to state). These experiments were repeated in December 2023, January 2024, and February 2024. This compiled dataset has been organized and cleaned in preparation for further analysis. Locations and cultivars included in experiments conducted in winter of 2023-2024: Iowa: Concord, Marquette, Petite Pearl, Minnesota: Clarion, Frontenac, Itasca, Marquette New York: Cabernet Sauvignon (2 locations), Concord, Marquette, Riesling Pennsylvania: Concord, Marquette South Dakota: Marquette Texas: Cabernet Sauvignon, Concord, Riesling Wisconsin: Frontenac, Marquette (2 locations), Petite Pearl Objective 2. Model implementation and site selection. Phase 1/Year 1 (complete): End user requirements and technical information was gathered and compiled from project PIs, model researchers, and extension experts. Phase 2/Year 1 (90% complete):A user interface (UI) for preliminary testing has been completed. User experience and user interface (UX/UI) feedback has been collected from a small group of extension professionals.
