Wilding pines in New Zealand threaten hydropower generation and tourism, particularly in Queenstown. Each year, 6,000 wilding trees are removed from Cecil Peak, costing about $110,000 annually, with a projected budget of $1 million over the next years.

Farmers pay up to $60,000 yearly for control efforts. Studies indicate that wilding pines can reduce water yield by 20%, leading to a loss of 330 megawatts from hydroelectric schemes. Despite a favorable cost-benefit ratio for investments in pine control, government funding remains inadequate, risking further economic and ecological consequences.
