    Controlling Non-Native Plants in Ohio Forests: Callery Pear

    Feb 17, 2026

    Callery pear (Pyrus calleryana), often referred to by the cultivar name “Bradford pear,” is native to Asia. Its seed was initially brought to the United States in the early 20th century to serve as genetic material for breeding fire blight resistance in native pears in the Pacific Northwest. By 1950, Callery pear was recognized for its horticultural potential, especially its production of showy white flowers in early spring (Figure 1).

    Beef Cattle Handling: Physiology and Behavior

    Feb 12, 2026

    You have heard of horse sense. Well, to get cattle to do what you want takes knowledge of animal behavior, access to good facilities, and proper handling techniques. Collectively, these items add up to “cow sense”. Animal-related injuries to employees can be due to the preoccupation, impatience, or anger of the animal or its handler. During these moments, a livestock handler needs to understand animal behavior. Well-designed facilities do not make up for a lack of cow sense.

    Cressleaf groundsel (Packera glabella, formerly Senecio glabellus) has spread in Ohio since the early 1900s. With the adoption of no-till or reduced tillage, cressleaf groundsel has become more prevalent in Ohio across a variety of cropping fields, pastures, and other landscapes. Also called butterweed, this plant can spread aggressively. It has poisonous characteristics, making it a potentially toxic weed for livestock.
