• Indicator of conservation success
• Invasion of natural ecosystems
• Competition with native vegetation
Why is monitoring exotic invasive vegetation important to TLC?

• To create a method for measuring the extent of exotic invasive vegetation.
• To make this method user-friendly and repeatable for volunteers of the Triangle Land Conservancy.
• Demonstrate how our method can be used in several test areas, including riparian areas in NCSU main campus, Centennial Campus, and Schenck Forest.

Simple Materials
• Rope with pre-measured lengths (2m, 5m) and stake attached• Clipboard with data sheet, percent cover card, and plot layout• Diameter tape (record units on data sheet) • Metric tape measure (100m)

Recommendations
• Data collected can be evaluated over time to determine increases or decreases in exotic invasive vegetation per site
• Exotic invasive species identification training session for volunteers
• Survey when species are most visible

Common: Multiflora roseScientific: Rosa multiflora
• Alternate leaf arrangements (one leaf with 5 leaflets in picture)
• 5-11 leaflets per leaf• Leaf edges serrated• White flowers with 5 petals
bloom in early summer• Thorn-like prickles on stems• Long arching stems, can be
vine-like

Conclusion
• Method is repeatable and user-friendly• Method can be adjusted to accommodate
different cover types• Comparing data over time will alert TLC
to exotic invasive vegetation problems• Early detection allows for intervention
