When did the swamps in the maritimes form?

The swamps in the Maritimes, particularly in regions like New Brunswick and Nova Scotia, began to form during the Holocene epoch, which started around 11,700 years ago after the last Ice Age. As glaciers receded, they left behind depressions and fertile soils that, combined with rising sea levels and changing climate conditions, facilitated the development of wetland ecosystems. Over thousands of years, these areas evolved into the diverse swamps and marshes we see today.
