Lancaster City – Tree Inventory and Municipal Street Tree PlanConclusions and Summary of RecommendationsConclusions• Maple species, red and Norway inparticular, are overabundant. The Cityshould increase both tree species andage diversity by limiting the planting ofthese tree species.• While there is an overabundance ofsome species, there is good overalldiversity of species. New plantingsshould focus on including a variety ofspecies, especially those occurringless commonly in the current inventory.• The overall age/size distribution oftrees was indicative of the patterns ofattrition with age typically seen inhealthy urban forests and reflectsongoing replacement of street trees.• A majority (74%) of the trees are inexcellent or good condition. Of these,the majority are in good condition(59% of total population).• 7% of the trees are in poor or deadcondition and should be removed.• About one-third of evaluatedsidewalks showed damage, mostlythought to be caused by trees.• The southeastern section of the City isparticularly under-stocked. Considerdirecting extra resources and attentionto this area.• Many residents encountered duringthe inventory were unaware of who isresponsible for maintenance of theCity street trees.Recommendations• Inspect all trees and update the treeinventory annually.• Address risk trees through removalor pruning in a timely manner.• Choose the proper species for eachplanting location.• Develop a cycle of annual treeremovals and plantings to achieveand maintain species and agediversity.• Monitor mature trees in decline,especially those in fair or poorcondition.• Use structural soils, plastic rootbarriers, and other tools along withproper tree selection and planting toreduce hardscape damage.• Consider developing tree plantingstandards for sidewalk and parkinglot plantings.• Through the use of porous concrete,curb cuts, grading, engineered soils,and bioretention basins, tie treeplantings into stormwatermanagement.• Increase public education andparticipation through tree-plantingand other related activities.• Consider adding a landscape designsection to the existing subdivisionand land development ordinancesand “Rules of Arbor Work” to thestreet and park tree ordinance.27
