Impacts Question 1.1 Impact on abiotic ecosystem processes Identify ecosystem processes impacted: Dead leaves changes soil nutrients, raising the nitrogen and increasing tannin levels. Sources of information: B Other Pub. Mat l back Langeland, K.. and K. Craddock Burks Identification and Biology of Non-Native Plants in Florida's Natural reas. IFS Publication SP 257. University of Florida, Gainesville. 165 pp. Rice, B Weed lert!: Sapium sebiferum. The Nature Conservancy, Wildland Invasive Species Team. Question 1.2 Impact on plant community composition, structure, and interactions Rev d Sci. Pub n back Identify type of impact or alteration: Tallowtree creates monotypic stands outcompeting surrounding native vegetation. In Texas, tallowtree has changed coastal prairies into woodlands dominated by tallowtree. Sources of information: Bruce, K.., Cameron, G. N., & Harcombe, P.. (1995).

Question 1.3 Impact on higher trophic levels Identify type of impact or alteration: lthough a food source for some birds, it lowers the diversity of plant species and bird species.

Question 2.5 Potential for human-caused dispersal Identify dispersal mechanisms: C Observational back Tallowtree is on the Texas Noxious Weed list and is not significantly being dispersed by humans. lthough it is commonly planted in landscapes and berries fall into the beds on vehicles and can be dispersed this way.

5 Question 2.6 Potential for natural long-distance dispersal Identify dispersal mechanisms: Birds carry seeds far distances. Seeds are also dispersed by water during flood events.
