Maples can also suffer from leaf scorch, which results from drought conditions or poor soil quality. Assessing maples involves checking for symptoms of these diseases, structural soundness, and environmental conditions that could exacerbate their vulnerabilities.
Ash Trees: Battling the Emerald Ash Borer
Ash trees were once abundant in Saint Louis but have faced significant decline due to the invasive emerald ash borer (EAB). This beetle infests ash trees, causing extensive damage and often leading to tree death. Assessing ash trees involves looking for signs of EAB infestation, such as D-shaped exit holes and canopy thinning. Given the severity of EAB impact, many ash trees require removal to prevent the spread of the pest and ensure public safety. Efforts to manage and replace affected ash trees are ongoing, highlighting the importance of continuous monitoring and intervention.
Elm Trees: Resilience Amid Challenges
Elm trees, particularly the American elm, were historically popular in Saint Louis for their graceful form and shade. However, Dutch elm disease (DED), a fungal infection spread by bark beetles, has drastically reduced their numbers. Despite this, disease-resistant varieties have been developed and planted. Assessing elm trees involves checking for DED symptoms, such as wilting and yellowing leaves, and ensuring that resistant varieties are not compromised by other stressors. Proper care and regular inspections help maintain the health and safety of elm populations.
Sycamore Trees: Majestic Giants with Potential Risks
Sycamore trees, recognized by their distinctive bark and large size, are common in Saint Louis. While generally robust, they can be susceptible to anthracnose, a fungal disease that causes leaf blight and twig dieback. Sycamores are also prone to structural issues due to their size and weight, making them a focus of risk assessments. Arborists examine sycamores for signs of disease, structural integrity, and potential hazards posed by their large branches. Managing these giants involves balancing their aesthetic and ecological benefits with the need for public safety.
