A WEED REPORT from the book Weed Control in Natural Areas in the Western United States This WEED REPORT does not constitute a formal recommendation. When using herbicides always read the label, and when in doubt consult your farm advisor or county agent. This WEED REPORT is an excerpt from the book Weed Control in Natural Areas in the Western United States and is available wholesale through the UC Weed Research & Information Center (wric.ucdavis.edu) or retail through the Western Society of Weed Science (wsweedscience.org) or the California Invasive Species Council (cal-ipc.org). Toxicodendron diversilobum (Torr. & A. Gray) E. Greene Pacific poison-oak Family: Anacardiaceae Range: Baja California to British Columbia. West of the Cascade Range in Washington and Oregon; ubiquitous in California west of the Sierra Nevada. Also along the western side of Nevada. Habitat: Mixed evergreen forests, woodlands, chaparral, coastal sage scrub, and riparian zones. It is one of the most widespread shrubs in California. It generally occurs on acid soils, but is not limited to any particular soil type, texture or drainage pattern. Pacific poison-oak is typically found at less than 5,000 ft elevation and grows on all aspects. It can tolerate drought, fire, and low temperatures. Origin: Native to the Pacific Coast of the western United States from British Columbia to Baja California. Impacts: One of the most hazardous native plants in the western states. It can be problematic wherever people are likely to contact the plant such as along trails or during brush removal around homes, along rights-of-way, fire breaks, construction sites, etc.

Poison Ivy (Toxicodendron Radicans) DESCRIPTION
Weed Identification and Control Sheet: www.goodoak.com/weeds Poison Ivy (Toxicodendron radicans) DESCRIPTION: Poison ivy is a native woody vine and member of the sumac family. It can be found in shady and sunny sites rambling along the ground, forming a small shrub, or climbing up trees. The vines attach to surfaces by means of thin aerial roots which grow along the length of the stem. The plant always has three leaflets which are often serrated. Usually these leaflets have one dominant lobe, giving the outer two leaves the appearance of mittens with the central leaf resembling a mitten with two thumbs. Young leaves are often dark green or maroonish, and the attractive fall foliage can range from brick to fire- engine red. Poison ivy is generally not considered a threat to native plant communities, in fact, the white berries provide winter food for birds and deer relish the foliage. Though harmless to most animals, many humans are allergic to the urushiol (yoo-roo-shee-ol) oil produced by the plant which results in itching, inflammation and blisters. This oil is found in all parts of the plant during all times of the year. This oil can also be spread by contact with clothing, shoes, pets or equipment that have touched poison ivy weeks or months after initial contact. It can even be transmitted in the air when poison ivy is burned, which presents a severe risk if inhaled and has been known to result in hospitalization and death. Though some people are not alleargic to the oil, its important to wear pants, long sleeves and gloves when working around poison ivy since the allergy can develop af- ter repeated exposures to urushiol.

Non-Native Invasive Plants of the City of Alexandria, Virginia
March 1, 2019 Non-Native Invasive Plants of the City of Alexandria, Virginia Non-native invasive plants have increasingly become a major threat to natural areas, parks, forests, and wetlands by displacing native species and wildlife and significantly degrading habitats. Today, they are considered the greatest threat to natural areas and global biodiversity, second only to habitat loss resulting from development and urbanization (Vitousek et al. 1996, Pimentel et al. 2005). The Virginia Department of Conservation and Recreation has identified 90 non-native invasive plants that threaten natural areas and lands in Virginia (Heffernan et al. 2014) and Swearingen et al. (2010) include 80 plants from a list of nearly 280 non-native invasive plant species documented within the mid- Atlantic region. Largely overlapping with these and other regional lists are 116 species that were documented in the City of Alexandria, Virginia during vegetation surveys and natural resource assessments by the City of Alexandria Dept. of Recreation, Parks, and Cultural Activities (RPCA), Natural Lands Management Section. This list is not regulatory but serves as an educational reference informing those with concerns about non-native invasive plants in the City of Alexandria and vicinity, including taking action to prevent the further spread of these species by not planting them. Exotic species are those that are not native to a particular place or habitat as a result of human intervention. A non-native invasive plant is here defined as one that exhibits some degree of invasiveness, whether dominant and widespread in a particular habitat or landscape or much less common but long-lived and extremely persistent in places where it occurs.

Scandent plants are high in conductive capability, but therefore have highly vulnerable hydrosystems; this survey attempts to see what kinds of adaptations exist for safety and in which taxa. A review of scandent dicotyledons reveals that a high proportion possesses vasi centric tracheids (22 families) or true tracheids (24 families); the majority of scandent families falls in these categories. Other features for which listings are given include vascular tracheids, fibriform vessel elements, helical sculpture in vessels, starch-rich parenchyma adjacent to vessels, and other parenchyma distributions. The high vulnerability of wide vessels is held to be countered by various mechanisms. True tracheids and vasicentric tracheids potentially safeguard the hydrosystem by serving when large vessels are embolized.
