2 Invasive Plant Citizen Science Quiz Question 1
What adaptations do invasive species have that enable them to outcompete native species? Ability to secrete a chemical into the soil that inhibits germination of other species More efficient at removing nutrients from soil Unpalatable to grazing animals Extreme resilience All of the above

3 Answer to Question 1 What types of adaptations do some invasive species have that make them able to outcompete native species? Ability to secrete a chemical into the soil that harms other species More efficient at removing nutrients from soil Unpalatable to grazing animals Extreme resilience All of the above

4 Invasive Plant Citizen Science Quiz Question 2
Name this species: B. Legler

5 Answer to Question 2 Name this species: St. Johnswort (Hypericum perforatum) D. Visalli N Rees, Invasive.org B. Legler Note the 5-petaled yellow flowers at the top of branches, with black dots along petal margins, rust- colored stems, and oval leaves. Hold a leaf up to the light to check for transparent dots.

6 Invasive Plant Citizen Science Quiz Question 3
Name this species: J.M Randall, The Nature Conservancy

7 Answer Question 3 Name this species: Houndstongue (Cynoglossum officinale) M.E. Harte, Invasive.org B. Legler J.M Randall, The Nature Conservancy NPS photo Note the velvety-hairy leaves that are broad at the base and gradually smaller towards the top and the small, 5-petaled reddish-purple flowers, some of which may have matured into velcro-like burs.

8 Invasive Plant Citizen Science Quiz Question 4
Name this species: M. Shephard, Invasive.org

9 Answer Question 4 Name this species: Spotted Knapweed (Centaurea stoebe) B. Legler B. Legler B. A. Rice, The Nature Conservancy Note the pinkish-purple flowers on branch tips, with bracts tipped with brown comb-like fringe. Also note the coarse texture of the foliage and the alternate, deeply lobed leaves covered in fine greyish hairs.

10 Invasive Plant Citizen Science Quiz Question 5
Name this species: Weed Science Society of America

11 Answer Question 5 Name this species: Yellow Toadflax (Linaria vulgaris) NPS Photo D. Visalli S. Askew, Virginia Tech Note the dense clusters of yellow flowers with a fuzzy orange spot on lower lip and a downward-pointing yellow spur and the narrow, linear waxy-smooth leaves attached directly to stem.

12 Invasive Plant Citizen Science Quiz Question 6
Name this species: S. Askew, Virginia Tech

13 Answer Question 6 Name this species: Oxeye Daisy (Leucanthemum vulgare) B. Legler B. Legler B. Legler Note the daisy-like flowers on the end of each stem and the green bracts with brown margins in several overlapping rows underneath the flowers. Also note the alternate, toothed stem leaves that lack stalks.

14 Invasive Plant Citizen Science Quiz Question 7
Which of these is an Oxeye Daisy rosette (first year growth of leaves before flowering in second year): J.M. Ditomaso, UC Davis J.M. Ditomaso, UC Davis

15 Answer Question 7 Oxeye Daisy rosette
J.M. Ditomaso, UC Davis J.M. Ditomaso, UC Davis Oxeye Daisy rosette Note the spoon shaped leaves with wavy, scalloped margins and long, narrow stalks Houndstongue rosette Note the velvety-hairy, oval leaves with pointed tips and entire margins

16 Invasive Plant Citizen Science Quiz Question 8
Which of these is a Spotted Knapweed rosette: J.M. Ditomaso, UC Davis J.M. Ditomaso, UC Davis

17 Answer Question 8 Yellow Toadflax rosette
J.M. Ditomaso, UC Davis J.M. Ditomaso, UC Davis Yellow Toadflax rosette Note the smooth, waxy, pale green leaves that are linear, narrow and attached directly to the stem Spotted Knapweed rosette Note the coarse, deeply-lobed leaves covered in fine greyish hairs, attached by long stalks.

18 Invasive Plant Citizen Science Quiz Question 9
Which one is the invasive St. Johnswort, Hypericum perforatum? cm ( inches) tall 1 m (3 feet) tall NPS photo B. Legler

19 Answer Question 9 NPS photo B. Legler Native St. Johnswort, Hypericum scouleri, is typically found at higher elevations, is smaller and lacks transparent dots on the leaves Invasive St. Johnswort, Hypericum perforatum is larger and generally has narrower leaves with transparent dots that can be seen when held up to the light

20 Invasive Plant Citizen Science Quiz Question 10
Which species is Houndstongue? B. Legler B. Legler

21 Answer Question 10 Houndstongue Oblongleaf bluebells
B. Legler B. Legler Houndstongue Cynoglossum officinale Note the reddish-purple flowers and pointed tipped leaves Oblongleaf bluebells Mertensia oblongifolia Note the similar foliage but more rounded leaves and blue flowers
