1	"Invasive Species" Invasive Species: Canadian Thistles
2	Insects infested the White Pine forest resulting in the deforestation of the White Pines in January 2007. Environmentalists planted different trees in April 2007 to replace the White Pines.

10	"This is our research question" This is our research question: To what extent does the invasive species, Canadian Thistle, impact the natural succession process in the clear cuts at Harford Glen?
11	Data Collection Tool We took a total population survey of the Canadian Thistle plants in the clear-cuts at Harford Glen.
12	"We mapped the Canadian Thistle..." We mapped the Canadian Thistle on our GPS We plotted our findings on a map ( every plant had its own entry)
13	Total Population Count-Canadian Thistle 2008
14	"There are about 1,120 Canadian..." There are about 1,120 Canadian Thistle plants growing in 2 out of the 3 cut areas of Harford Glen. Canadian Thistle usually grows together Canadian Thistle is very thorny Canadian Thistle is an invasive plant Canadian Thistle spreads its seeds like a dandelion

17	Recommendations To not spray herbicides in the clear cut areas. (kills all plants) Investigate different herbicide options. To have a student committee to come once a year (Envio. Summit) to develop a forestry management plan. Continue to cut thistle seed heads and dispose of properly. Find a use for the thistle without spreading it.(Fire starter, bird feed, etc.)
18	"While we were collecting data" While we were collecting data, we also did a fraction of our action plan. We were pulling off the flower heads and buds for two reasons. 1. So we wouldn’t count the same plant twice. 2. So the seeds couldn’t grow more Canadian thistle
