A series of experiments was conducted to examine fire spread along fences subjected to wind at various speeds and angles. Specifically, sections of western redcedar, California redwood, or vinyl privacy fences were ignited with a burner. Wind fields of 9 m/s, 13.5 m/s, or 18 m/s aligned with, perpendicular to, or at a 45 angle to the fences were applied during the experiments. To simulate fine fuels typically present in real installations, dried shredded hardwood mulch beds were placed under most of the fence sections. Also, some fence sections were coated with fence preservative to assess its effect on fire spread. Pans of mulch were downwind targets for firebrands produced by the burning fence and mulch bed. At all wind speeds tested, a mulch bed was required for flames to spread. Fastest flame spread was achieved with the fence aligned with the wind field. During most experiments, the burning mulch and fences produced firebrands which ignited spot fires in the mulch targets. These experiments demonstrated that ignited wood fence structures can be rapid conduits for fire along them and potentially spread fire to attached or adjacent structures. Additionally, it was found that burning fences can produce spot fires from their own firebrand generation. This study of fence fire spread is part of a series designed to better inform standards and codes regarding placement of landscape features around homes at risk of exposure to wildland-urban interface fires.

This document provides managers with a literature synthesis of the historical conditions, current conditions, fire regime condition classes (FRCC), and recommended treatments for the major ecosystems in southern Utah. Sections are by ecosystems and include: 1) coniferous forests (ponderosa pine, mixed conifer, and Engelmann spruce-subalpine fir), 2) aspen, 3) pinyon-juniper, 4) big and black sagebrush, and 5) desert shrubs (creosotebush, blackbrush, and interior chaparral). Southern Utah is at the ecological crossroads for much of the western United States. It contains steep environmental gradients and a broad range of fuels and fire regimes associated with vegetation types representative of the Rocky Mountains, the Great Basin, Northern Arizona and New Mexico, and the Mohave Desert. The Southern Utah Demonstration Area consists of contiguous state and federal lands within the administrative boundaries of the Bureau of Land Management (BLM), Fishlake and Dixie National Forests, National Park Sevice, and State of Utah, roughly encompassing the southern 15 percent of Utah (3.24 million ha). The vegetation types described are similar in species composition, stand structure, and ecologic function, including fire regime to vegetation types found on hundreds of millions of hectares in the 11 western states.
