Long Lake Provincial Park in Halifax, Nova Scotia. Map & Guide: www.halifaxtrails.ca/long-lake-provincial-park/
The dense foliage in a stand of hemlocks creates an environment that is cooler, moister and darker than the surrounding forest. As the evergreen needles fall the soil becomes more acidic. Under these conditions few if any species can compete so the hemlock regenerates and grows as pure stands which can live for 600 years or, in some cases, as much as 1,000 years.
