1) Based on the video, how would you define an invasive species? Besides cogongrass, what is another problematic, invasive species plant in Florida? Write a brief paragraph describing this species, including full scientific name, key identifying characteristics, where is grows (native range and here in Florida), why it is problematic, and how it is managed or controlled 2) Why could drought and invasion in combination can impact native plant communities? How does the Biven's Arm experiment test for this interaction? (Note: BE SPECIFIC! Your answer should include all treatments, including the control), species included in the study, the general experimental design/layout, and data collected. 3) How did soil moisture change in the plots over time (make sure to include all plot types in your answer? Why do the researchers think that the cogongrass invasion ameliorated the effects of the drought conditions? Explain in detail how this impacted pine survival in the plots. Why might this information be important to land managers where cogongrass may interact with native species? 4) How did the cogongrass invasion impact native species cover and richness in the plots? What characteristics of cogongrass might allow it to have such strong impacts on native plants communities (you will have to research this!). Do you think all invasive plants have similar impacts on native plant communities? Explain your
