Wetland mapping and monitoring in the Regional District of Nanaimo
MetadataShow full item record
Wetlands play a pivotal role within the Regional District of Nanaimo (RDN), including the Mount Arrowsmith Biosphere Region (MABR), providing ecosystem services and significant value to the region. Wetlands in this region face threats including climate change, hydrological changes, urban development, and resource extraction; therefore, it is important that we have a more in-depth understanding of their local roles. This study looks at what part wetlands play in groundwater recharge or discharge. Instrumentation was installed at three sites within the MABR, collecting water levels in three piezometers installed at different depths, precipitation, and daily site photos, with data downloaded every three months and compared to data from the nearest climate, hydrometric, and observation well stations. Data interpretation is still in the initial stages and more data is required in order to confidently conclude the role these selected wetlands have with regards to their connection to the underlying aquifers of the region.
