American Forest's report on Milwaukee's 'forests' reads:
Milwaukee has a long history of urban forestry. Past struggles with Dutch elm disease and current ones with emerald ash borer (EAB) have led the city to implement diversification plans, as well as develop comprehensive inventories of its trees. With the exception of the city’s ash trees, which are battling the ravages of EAB, the city’s street trees are in excellent condition. Milwaukee has 25 acres of park per 1,000 residents. Its urban forest provides $15 million in stormwater savings and removes 496 tons of pollution annually — a value estimated at $2.59 million.
