Geocache Description:

The Kortright Marsh


At the Kortright Marsh there is a bird blind, boardwalk, and raised viewing platform. This marsh was created in 1977 by berming (dredging and piling up fill) and creating a diversion of drainage when needed with waters from Cold Creek. The outflow is the red structure by the bird blind. Wetlands, like a marsh, are important to our planet for many reasons including: nesting, feeding and resting habitat for migratory waterfowl; creation of food chains/web; habitat to a variety of mammals and shore birds; etc. One of their most important roles is to clean water as they are the 'planet's kidneys'. Of special note to this marsh is the returning pair of trumpeter swans which return every year.

In geography, a marsh, is a type of wetland that is subject to frequent or continuous flood. Typically the water is shallow and features grasses, rushes, reeds, typhas, sedges, and other herbaceous plants. Woody plants will be low-growing shrubs. A marsh is different from a swamp, which has a greater proportion of open water surface and may be deeper than a marsh. In North America, the term "swamp" is used for wetland dominated by trees rather than grasses and low herbs.

In order to log this earthcache you will need to perform the following tasks and email me the answers. You can perform the following tasks as you walk along the boardwalk and while visiting the viewing platforms.

a) Approximate the size of the marsh. Use the far shore and berms around the edge as a perimeter. Use acres or hectares. (A hectare is 100mx100m or 2.5 acres) Hint: One of the signs gives the answer. Compare what you calculated to what is mentioned on the sign. How close are you?

b) From the viewing platform decide how much of the original water portion of the marsh has disappeared. (View to north will add some insight here.)

c) Is the dominant plant growing in this area cattails or bull rushes?

d) Why would the water level be so low? You can ask Kortright staff for help if needed, but there are some obvious answers.

e) Using the signage if necessary submit the name of one example of each of the following which frequents the marsh at Kortright: mammal, bird (water); bird (shore); reptile; amphibian; mollusc/crustacean; fish. Did you see any of these, if so, which ones.
