For more details about the Mer Bleue reports, due dates and corrections, please visit the lab website. Site description The Mer Bleue conservation area is a protected wetland of a little more than 30 km2 and is located about 10 km southwest of Ottawa (see map on website). This area is particularly important for the conservation of its biodiversity, as it represents one of the last relatively intact bogs in southern Canada. It is a refuge for certain plant and animal species that are threatened by extinction, for instance, the spotted turtle (Clemmys guttata). 1 0 Lab 1 ‐ Distribution of plants at Mer Bleue The vegetation found there is similar to that found many hundreds of kilometres to the north, in the boreal forest. About half of the conservation area's surface is a raised or domed bog. The sphagnum mosses found therein release acids that significantly reduce microbial activity. Since decomposition is slowed or almost stopped, dead moss accumulates slowly (over hundreds, even thousands of years) and eventually fills the ponds or lakes until it forms a dome, as in Mer Bleue. The semi‐aquatic acid habitat that results is colonized by specific types of plants that you will see, such as: blueberries, black spruce, leatherleaf, larches, etc. The raised bog at Mer Bleue is adjacent to a marsh dominated by cattails and home to beavers and muskrats. At the edge of the wetland you will find sandy dunes or ridges that are colonized by vegetation normally found on drier soils (basswood, sumac, etc.) or by conifer plantations. Your task You will visually sample the vegetation at 5 stations in Mer Bleue by recording which of the plants listed in the lab manual are present in your sampling area.
Back from the field trip, you will enter your observation in the BIO1130‐Labs virtual campus site. This way, the observations of all students will be combined in one big file. One week after your lab, hand in your assignment using the combined data corresponding to the species that has been assigned to you. Your lab report will include: 1‐ A Graphical analysis of the data, by plotting a graph showing the incidence of your plant throughout the 5 observation stations (ordered in a dry to wet gradient). 2‐ Answers to the questions listed in the instruction file located on the lab website at: web5.uottawa.ca/avaron/BIO1130/ The instruction file on the lab website contains additional information about the Lab 1 assignment.
