Does Highlands Ranch require permits for tree removal?
Douglas County does not require permits for tree removal on private residential property unless trees are located within protected riparian buffers or open space easements. However, most Highlands Ranch properties fall under HOA jurisdiction with their own approval requirements. We coordinate with your specific HOA's architectural review committee to obtain necessary approvals before beginning work.
How serious is the emerald ash borer threat in Highlands Ranch?
EAB is a confirmed and active threat in Douglas County, first detected in 2013 and now widespread throughout the region. Highlands Ranch's green ash population, planted extensively during the 1980s and 1990s, is directly at risk. Preventive trunk injection treatments protect individual trees for up to two years. We assess each ash tree to determine whether treatment or planned removal and replacement is the better long-term investment.
What causes yellowing leaves on my maple trees?
Iron chlorosis — yellowing foliage with green veins — is extremely common in Highlands Ranch due to naturally alkaline soils that prevent trees from accessing iron. Maples, oaks, and pin oaks are particularly susceptible. Our iron chelate injection treatments correct deficiencies and restore healthy green foliage within one growing season. Untreated chlorosis progressively weakens trees and increases vulnerability to pests and diseases.
What tree species do you recommend for replanting in Highlands Ranch?
For Highlands Ranch's high plains climate and alkaline clay loam soils, we recommend disease-resistant elms (Accolade, Triumph, Princeton), Kentucky coffeetree, Autumn Blaze maple, Ohio buckeye, and bur oak for shade trees. Ornamental options include Prairifire crabapple, serviceberry, and hawthorn varieties. We avoid blue spruce and Austrian pine given their declining health throughout the community and recommend native ponderosa pine or limber pine for evergreen plantings.
How do you work with Highlands Ranch HOAs?
We have extensive experience with Highlands Ranch HOA requirements and approval processes. We prepare complete submission packages including project descriptions, arborist assessments, replacement planting specifications, and insurance certificates. We communicate directly with architectural review committees and can attend hearings when necessary to support approval requests.
How often should mature trees in Highlands Ranch be pruned?
Mature shade trees benefit from professional pruning every 3–5 years under normal conditions. Trees with known structural defects, rapid growth patterns, or proximity to structures and utility lines may require more frequent attention. Spruce and pine experiencing needlecast or tip blight often need annual deadwood removal to maintain canopy health and appearance. We develop customized maintenance schedules based on species, age, condition, and site factors.
