Peatlands

Question 0

Requires significant organic matter production,

Answer 0

In excess of decomp.

Question 1

Significant amounts of partly

Answer 1

Decayed plant material.

Question 2

Require restricted drainage,

Answer 2

Limiting the removal of dissolved or particulate carbon.

Question 3

Hydrology is dominated by

Answer 3

Precipitation, therefore peatland is nutrient poor.

Question 4

Reduced decomp rates from combination of

Answer 4

Cool temperatures and anaerobic conditions.

Question 5

Can be subdivided into

Answer 5

Bogs and fens; depending on hydrology.

Question 6

Bogs: isolated from groundwater, main water supply is from

Answer 6

Precipitation.

Question 7

Bogs: Have a low pH and are

Answer 7

Nutrient poor.

Question 8

Bogs: Dominated by mosses,

Answer 8

Sedges and low woody shrubs, with thick leaves to reduce nutrient loss and herbivory as they would be difficult to digest.

Question 9

Fens: Receive some groundwater or through flow, therefore are

Answer 9

More nutrient rich

Question 10

Fens: Dominated by sphagnum, or by

Answer 10

Mosses, sedges, grasses (with increasing nutrient availability).

Question 11

Generally less productive than

Answer 11

Other vegetation communities in the same zone and less productive than other wetlands.

Question 12

Water table is generally near the

Answer 12

Surface and relatively constant over the year.
