Understanding tree transpiration variability is vital for assessing ecosystem water-use efficiency and forest health amid climate change, yet most landscape-level measurements do not differentiate individual trees. Using canopy temperature data from thermal cameras, we estimated the transpiration rates of individual trees at Harvard Forest and Niwot Ridge. PT-JPL model was used to derive latent heat flux from thermal images at the canopy-level, showing strong agreement with tower measurements (R2 = 0.70–0.96 at Niwot, 0.59–0.78 at Harvard at half-hourly to monthly scales) and daily RMSE of 33.5 W/m2 (Niwot) and 52.8 W/m2 (Harvard). Tree-level analysis revealed species-specific responses to …

Drought is one of the important factors that cause a decrease in productivity and quality in plant cultivation. Stress tolerance in plants can be increased or damage can be reduced by various exogenous applications. One of them is flavonoids, which have an important role in the response to stress through changes that occur at the endogenous level in the plant due to drought stress. The effects of exogenous treatment of chrysin, a member of the flavonoid group, on tomato seedlings grown under water deficit were examined. Different doses (C0: Control with no treatment, C1: 0.1 mM, C2: 0.5 mM and …

Perceptions Of Spruce Budworm Monitoring, Management, And Remote Sensing Technology In Maine's Forest Sector, Allison E. Foster, Adam Daigneualt, Parinaz Rahimzadeh-Bajgiran, Aaron Weiskittel
Maine Policy Review
Eastern spruce budworm (Choristoneura fumiferana Clem; SBW) is a native forest pest that can severely damage spruce-fir forests in Maine. Monitoring SBW defoliation and populations is important to ensure forest managers make timely decisions regarding forest management. This research brief presents the results of a survey of Maine’s large forest owners and managers. Our findings indicate a need for clear policies and collaborations between forest organizations to prepare for a SBW outbreak. While many forest organizations use satellite imagery, personnel capacity and lack of knowledge are barriers to using remote sensing. We recommend strengthening forest health programs by hiring a …

The Great Lakes Entomologist
In the eastern United States abiotic forest disturbances are common and cause extensive tree damage. Freshly broken trees and tree branches attract bark and ambrosia beetles that utilize inner bark and xylem of damaged branches and trees to fill requisite habitat needs. An ice storm in February 2003 on the Wayne National Forest presented an opportunity to study the local ambrosia beetle species and their reaction to this storm event. Ethanol baited Lindgren traps were deployed from 2003-2006 starting in the summer after the storm. Eight native and introduced Scolytinae ambrosia beetle species were trapped in large numbers (>500 …

Tree Diversity Across The Minneapolis-St. Paul Metropolitan Area In Relation To Climate And Social Vulnerability, Adrienne B. Keller, Leslie A. Brandt, Jeannine Cavender-Bares, Joseph F. Knight, Sarah E. Hobbie
Michigan Tech Publications, Part 2
Urban tree canopy cover is often unequally distributed across cities such that more socially vulnerable neighborhoods often have lower tree canopy cover than less socially vulnerable neighborhoods. However, how the diversity and composition of the urban canopy affect the nature of social-ecological benefits (and burdens), including the urban forest's vulnerability to climate change, remains underexamined. Here, we synthesize tree inventories developed by multiple organizations and present a species-specific, geolocated database of more than 600,000 urban trees across the 7-county Minneapolis-St. Paul (MSP) metropolitan area in the Upper Midwest of the United States. We find that tree diversity across the MSP …

Soil moisture is a critical parameter that significantly impacts the global energy balance, including the hydrologic cycle, land–atmosphere interactions, soil evaporation, and plant growth. Currently, soil moisture is typically measured by installing sensors in the ground or through satellite remote sensing, with data retrieval facilitated by reanalysis models such as the European Centre for Medium-Range Weather Forecasts (ECMWF) Reanalysis 5 (ERA5) and the Global Land Data Assimilation System (GLDAS). However, the suitability of these methods for capturing local-scale variabilities is insufficiently validated, particularly in regions like South Korea, where land surfaces are highly complex and heterogeneous. In contrast, artificial intelligence …

Building Gender Equity In Forestry Education: The Benefits Of Oregon’S Women Owning Woodlands Network, Lauren A. Grand, Tiffany Hopkins
The Journal of Extension
The Women Owning Woodlands Network was launched in 2005 as a way to provide collaborative and hands-on peer learning education to women who felt uncomfortable participating in traditional Extension programs. Since its inception the program as grown to provide education and resources for over 300 women. We surveyed these women to identify if the program continues to meet their needs. It is evident that WOWNet has continued to be an important part of OSU FNR’s outreach education program and continues to meet the needs of a historically undeserved group of landowners in ways that traditional programming does not.
