Environmental Stewardship

Go GREEN with the Environmental Stewardship Team

The Environmental Stewardship Division of the Community Services Department works with communities, groups and individuals to promote sustainable living, environmental protection and education throughout the municipality. We work to develop community programs and initiatives to increase environmental awareness, engage the community in environmental projects and establish new partnerships. Township staff offers assistance with project development and coordination, fundraising and marketing.

Ongoing Projects
  • Delivering community education programs and workshops in partnership with various organizations
  • Subsidizing compostable food service products to community groups
  • Tall Grass Prairie Restoration initiative
  • Reducing mowing by increasing naturalization through tree, shrub and wildflower plantings
  • Terrestrial invasive species monitoring and mapping throughout King Township
  • Increasing educational signage throughout the municipality
  • Enhancing existing and creating new habitats for pollinators in parks, gardens and naturalized areas to support our Bee City Certification & Mayors Monarch Pledge
  • ​Identify new environmental funding opportunities

Greening Initiatives

European Gypsy Moth Lymantria Dispar Dispar (LDD Moth)

From now until late- April you can protect your trees by scraping egg masses into a bucket of soapy water. Manual egg mass removal will help reduce the number of hatched caterpillars in the spring. For more information please see the Management & Removal section below.

The European Gypsy Moth also known as Lymantria dispar dispar (LDD), is an invasive insect found throughout southern Ontario that feeds on hardwood and some softwood tree species. They get their name from their ability to travel by attaching to various objects. The LDD moth population generally surges every 7 to 10 years and the increase usually lasts for 1 to 3 years. 

Use of the name Gypsy Moth could be perceived as culturally insensitive. Alongside York Region, the Township of King will educate and build awareness for replacing the name Gypsy Moth by introducing the Latin name Lymantria dispar dispar (LDD).

LDD caterpillars begin to appear in May and evolve into moths in late July/ early August. The caterpillars eat leaves causing the trees to lose some or in extreme cases, all their canopy. Favoured tree species include oak, birch, poplar, willow and maple. Healthy trees are able to regrow their leaves during the same growing season within two to three weeks. While most healthy trees can withstand several years of severe defoliation, trees that are already in poor health may have a harder time recovering and can result in tree morality.  Additional stressors such as other pest/diseases or hot, dry weather may result in tree decline or mortality.

In some rare cases, when the numbers are extremely high as they were in 2021, the caterpillar will feed on evergreens such as pine and spruce. When it comes to evergreens, it may take longer for a coniferous tree to put out new needles then it would a deciduous tree to re-leaf. Provided the tree is relatively healthy it will have new growth at the outer tips of the branches where new growth appears every year. The needles on the inner branches will not grow back and as a result it may take many years before the tree is aesthetically appealing

Long term effects can be reduced or prevented through management techniques.
