2. Genetics within the same species may vary from eco-region to eco-region.
3. Different species within a plant community reduce competition by occupying complementary niches within the community.
4. In temperate zones within the US herbaceous species are generally the earliest stage of ecological succession.
5. Earthworm presence in a woodland soil indicates an optimal condition for plant establishment.
6. Canada Goldenrod will generally decrease diversity in a meadow due to its highly competitive nature.
7. Soil disturbance generally stimulates seed germination.
8. Cultivars of Native Species Do Not Attract Pollinators.

10. Cool season European grasses are generally mat forming.
11. Coefficients of Conservatism refers to the elevation in which a plant commonly occurs.
12. Lands with a high level of disturbance history are most likely to be dominated by indigenous species.
13. Habitat Fidelity refers to the need for a plant to grow in a highly fertile condition.
14. Ecotone refers to a transitional area between two different vegetation types.
