ORAM Metric 6

Metric 6: Plant communities, interspersion, microtopography The final metric is designed to evaluate what kinds of plant communities are inhabiting the wetland under study. Certain kinds of plants can tolerate and prefer living close to or in heavily saturated areas; even in the water. This is a major indicator of what grade of wetland you will have after completing the scoring sheet. The first section of this metric asks you to score wetland vegetation communities on a scale from 0 to 3. The description for each number can be found to the left of the vegetation community boxes. A common question from the vegetation community section is what is a mudflat? Mudflats, also known as tidal flats, are coastal wetlands that form when mud is deposited by tides or rivers. Mudflats can be found along the coast of Lake Erie. The second section of metric six asks you to score the horizontal interspersion of the wetland. Interspersion is the intermixing of different habitat types or plant communities on an area of land. The more mixing of plant species in the wetland, the higher the degree of interspersion. If you need more help with this question, there is a diagram in your backpack kit. Section C of metric six asks about coverage of invasive species. Below is a list of invasive species that could be found around you: Section D of metric six asks you to score the microtopography of the wetland on a scale from 0 to 3. The description for each number can be found to the right of the scoring box. A common question from this section is what is the difference between a hummock and a tussock. Hummocks are wooded areas that lay above the level of an adjacent marsh. Tussocks are a tuft or clump of growing grass.
