Parks / New
Brunswick / Kouchibouguac
Some 300 million years ago,
deposits of sand, silt and clay from the emerging
Appalachian Mountains compressed into the sandstone
and shale that makes up the parks bedrock.
As glaciers retreated 15 000 years ago, they
left loose rock deposits on the land while melting
ice raised the sea level and submerged the coast.
Waves and currents reduced the glacial fill
to small particles that built up over time to
form the elongated sand spit extending the entire
length of the Kouchibouguac Bay. This barrier
still calms and controls the effects of the
sea, sheltering estuaries, lagoons and salt-water
marshes to create nutrient rich mud flats. The
unique system of barrier islands, dunes, spits
and marine intertidal flats link land and sea
in a constantly shifting and varied ecosystem.
The hinterland of Acadian forest that conceal
cedar swamps and bogs, the salt marshes, shallow
estuaries, and fresh water streams that mix
with the lagoons, all provide a diverse and
varied habitat for plants and wildlife.
