City of Oxnard Urban Forestry and Tree Program Review

The City of Oxnard’s Tree Program Review provides a road map for the City to plan for the future of its trees. Dudek used a comprehensive approach to address issues associated with deferred maintenance, declining tree health, species diversity, out-of-date City tree policies, and infrastructure conflicts to develop the Tree Program Review.

5 Steps to Craft a Successful Urban Forest Management Plan in 2023

Urban forests play an important role in reducing surface temperatures, improving air quality, conserving energy, and increasing quality of life, amongst many other benefits. A sustainable urban forest must contain healthy, well-maintained trees with high species and age diversity. Creating such a robust urban forest can be complicated for cities and municipalities and is best

4 Vital Observations to Assess the Health of Blue Gum Eucalyptus Trees

Tasmanian blue gum eucalyptus (eucalyptus globulus) are ubiquitous in California. The species was imported as seeds from Australia during the Gold Rush during the mid-1800s, in the hopes that the fast-growing trees’ wood could be used for construction, furniture making, and railroad ties. They were unsuitable for that use due to the propensity of the

How Sonic Tomography Helps Arborists Detect Unhealthy Trees to Keep Communities Safe

Drought and pests, as well as tissue and root damage, put many trees at risk for internal rot and decay, which can pose a risk to property and public safety in the event a tree fails. Sonic tomography allows municipalities and developers to efficiently detect and accurately map tree decay in a non-invasive manner, especially

Trees are Infrastructure: Planning for Trees to Create Resilient, Equitable Communities

Planning for Trees Improves Climate Resiliency As the climate changes and the earth warms, extreme heat days (temperatures over 95°F) have increased in frequency and wildfires fueled by dry vegetation burn bigger and for longer, negatively impacting air quality both locally and nationally. While unable to completely cancel out the impacts of an extreme heat

How to Recognize and Manage an Invasive Shot Hole Borer (ISHB) Infestation

Invasive shothole borer (ISHB) is a group of two species of ambrosia beetles that are native to Southwest Asia. Suspected to have first arrived in Southern California in 2003, the beetles were previously misidentified as a less aggressive pest until approximately 2012. Since then, thousands of trees in forests, cities, and residential areas have become

Protected Tree Species: Limiting Development Impacts from Permit Application through Long-Term Monitoring

Limiting impacts to protected tree species takes place at four distinct points in time throughout project development. A thorough tree inventory informs and ensures a comprehensive Protected Tree Report. During construction, monitoring is essential to avoid impacts to protected species. Finally, long-term monitoring and management facilitate long-term health of protected tree species. Following, Dudek Urban

CalFire Grant Expands National City Urban Forest

National City — a small disadvantaged city in San Diego County — will expand its urban forest by planting 1,700 trees in city-managed properties with a $650,000 CAL FIRE grant. CAL FIRE’s Urban and Community Forestry Program focuses on using trees to provide neighborhoods the benefits of urban forests, such as sequestering greenhouse house gas,

California’s Urban Forests at Risk Due to Drought

Urban forests are the backbone of regional landscapes and represent a substantial natural resource investment. The 177 million trees in California’s urban forests are at risk as water cuts significantly reduce irrigation that is vital to mostly non-native, ornamental trees. Tens of millions of native trees in California’s wildlands have already died due to the

Rapid Assessment Monitoring Detects Early Threats to Drought-Stressed Native Oaks

California’s extended drought has put native oaks into survival mode as soils dry out at greater depths and water becomes less accessible. The trees conserve water use by decreasing transpiration and reducing the amount of tissue requiring water. At this stage, native oak trees are more susceptible to secondary pests and disease, invaders that attack
