Figure 7 - Value of imports of material with potential for introduction of invasive plant species, according to their destinations in Canada, 2001–2005.

Figure seven is a line graph with the y-axis representing the dollar value of imports in increments starting with ten million dollars and moving up to ten billion dollars. The values are plotted on a logarithmic scale. The x-axis represents the year from 2001 on the left through to 2005 on the far right. Value of imports is plotted on a logarithmic scale. Only provinces with more than ten million dollars in annual imports are included in the graph.

There are eight lines across the graph, each representing a province which imports materials with the potential for the introduction of an invasive plant, and the dollar amounts of the imports across years. From the top of the graph to the bottom, the dollar value of imports by Ontario is the greatest at about five hundred million dollars in each of 2001, 2002, 2003, 2004 and 2005; followed by British Columbia and Quebec at just over one billion dollars; Alberta; Manitoba and New Brunswick at about five hundred million dollars; Saskatchewan; and Nova Scotia whose imports were valued at about thirty million dollars in 2001, and rose to about sixty million dollars by 2005.
