Given the fоllоwing infоrmаtion, develop а strаtegy for the scenario given below. Give an appropriate goal, the approach(es) you would use, and the tool(s) you would use. YOU MUST JUSTIFY YOUR STRATEGIES - EXPLAIN WHY THEY ARE APPROPRIATE FOR THE SCENARIO. (4 points) Combating invasions – Goals 1. Prevention 2. Eradication 3. Exclusion/Containment 4. Suppression Must balance: -Work involved/expense -Chance of success -Scale of invasion (and detection) -Threats of the invasion (and treatment) -Support Combating invasions - Tools -Education -Barriers / filters -Pesticides (herbicides) -Slaughter / bounty -Mechanical treatments -Traps -Biocontrol Combating invasions – Approaches -Early detection / eradication -Pick your battles / triage -Work from the edge of infestations -Control propagule production -Enhance natives / competition -Use disturbances wisely SCENARIO: A prairie you manage has a large pristine calcareous fen and sedge meadow complex on it. The prairie preserve is two sections in size, a rectangle 2 miles long and a mile wide. On all borders of the preserve are gravel roads with ditches, and these ditches are filled with a monoculture of reed canarygrass. Reed canarygrass is known to be invasive in sedge meadows and fens. At present there are a few patches of reed canarygrass within the prairie, but mostly it is just in the ditches. You can only afford to put 30 people hours a year into controlling this invasion.
