Camosun Bog Restoration assignment -st

Image
5000 years ago, the Camosun Bog formed when a heavy block of ice created a depression in the land. Initially, it was a lake but over time it turned into a swamp and finally to a bog. In 1929, the City of Vancouver added drains because housing was intruding the area which made the bog really dry. Hemlock trees started growing in the area and were taken down in 1991. To help improve the bog conditions, sphagnum moss was planted. Volunteers from schools came to help restore the bog and without them,  the bog would not be what it is today. The Camosun Bog is quite important for the Musqueam people To Western people, they thought the bogs were unusable and had no meaning; however, to Musqueam people, the bog was important to them because it was part of their history. Grant states that draining a bog is essentially erasing the "evidence of the story Musqueam." and when a bog is completely drained it is removing all evidence of Indigenous people. They are unable to tell where...

Camosun Bog Restoration As early as 5000 years ago, the Camosun Bog started as a lake to a swamp and ending as a bog due to a depression in the land. The bog thrived, until 1929, when drains were installed, completely drying out the bog. The lack of water and nutrients caused the sphagnum moss to die, outcompeted by other invasive species. As a result, in order to restore the bog to its previous glory, volunteers had to remove many hemlock trees, lower the ground, and plant many sphagnum mosses.  The Camosun bog was important to Musqueam people. Urbanization was a means of calling the bog useless, unusable to Western people. However, to Musqueam people, it was an essential part of their history. To them, the bog told stories, memories, and was so full of life. Through the loss of the bog, it destroyed all traces of their previous history, as it was something that was always there before urbanization and everything else. It was a part of the land for so long, and to have the ori...

1. How was the bog formed? A bog is an ecosystem where plants are adapted to an acid environment, low nutrients, high water table, and little oxygen in the water. The bog is formed when a lake slowly fills up with plant debris. Sphagnum moss and other plants grow out from the lake's edge.  As sphagnum dies, more sphagnum grows on top of it. 2.  What is the keystone species of a bog?  Read about sphagnum moss.   How does Sphagnum maintain the acidic conditions?  The keystone species of a bog is sphagnum moss. The sphagnum moss is a plant that is favored by low oxygen, low nutrients, and moist acidic conditions. Sphagnum moss is sometimes referred to as peat is essential to a bog. Without sphagnum a bog would not exist. Sphagnum maintains acidic conditions by absorbing water and pumping hydrogen ions into its surroundings which creates a very acidic environment. 3.  What is peat?  How is it different from soil? Peat i...
