Mapped wetlands in the Backlands amount to approx. 6.5% of the total area, similar to the average for NS (6.6% in freshwater wetlands).<\/p>\n

However, smaller wetlands\/seasonal watercourses in the form of Boulder Fields, Mt Holly Washes, Vernal Pools and Whaleback Troughs in this landscape would likely more than double that figure. As documented by N. Hill* the water regime in the Halifax Backlands has features of dryland systems, with these intermittent stream courses probably accounting for a majority of the water flow. There are only a few bogs in the Backlands.

Wetlands\u2013natural defence against wildfires<\/strong><\/a>
\nArticle by Cathy Vaughan in the Chebucto News Vol 25(2) Oct 2023, pp1-2. “Wildfires have slammed our local communities recently and heightened our awareness of the results of human activity on climate change. Besides the practical tasks, such as emergency evacuation preparedness, we are now looking to the science of wetlands as a valuable and available natural defence against wildfires.<\/p>\n

\n“This report was written and prepared by Dr. Patricia Manuel, Mimi O’Handley(Ecology Action Centre), Becky Parker(Nature Nova Scotia), and a staff member from Halifax RegionalMunicipality.” Oct 2023, 14 pages. “On February 2, 2023, World Wetlands Day, the Ecology Action Centre, Nature Nova Scotia, and Halifax Regional Municipality (HRM) conducted interactive workshops on the protection and management of wetlands in Nova Scotia. Both workshops took place at the Captain William Spry Community Centre in Spryfield, HRM. The morning workshop, hosted by all three organizations, brought together primarily government and NGO stakeholders with interests in wetlands, natural areas, and watershed protection and management. The second workshop, hosted in the evening by the Ecology Action Centre and Nature Nova Scotia, was geared toward the general public.<\/p>\n

Vernal Pool Mapping in the Williams Lake Watershed, Halifax<\/a><\/strong>
\nProject Report by Huan Liu, Dalhousie School of Planning, 2012. This project tested several remote sensing approaches for documenting vernal pools by employing them individually in mapping potential vernal pools in the undeveloped area of the central Williams Lake Watershed. Field observations examined the accuracy of the predictions and an evaluation of the methods and data that this project used.<\/p>\n

Water quality measurements on Williams Lake and Colpitt Lake (Halifax, N.S.) Dec 7-13, 2015 with reference to possible impacts of road salt<\/a><\/strong>
\nReport to Williams Lake Conservation Company (WLCC) by David Patriquin, Jan 6, 2016. There is evidence for delayed (or possibly absence) of the fall turnover of the water column in Williams lake which may be related to salt induced stratification. Conditions have clearly deteriorated since 1990\/1991. Even though three-quarters of the watershed is undeveloped, salt inputs from the other 1\/4 are having significant impacts on the health of both Colpitt Lake and Williams Lake.<\/p>\n

\nAnna Bishop, ENVS 4902 Environmental Science Undergraduate Honours Thesis (on DalSpace) \u201c\u2026This project has provided baseline data on the characteristics and features of vernal pools in Halifax County, which lays the groundwork for future research in other geographic regions in NS. Ultimately, it provides some first steps towards protecting vernal pool ecosystems from anthropogenic impact within NS.<\/p>\n

Forested Wetlands in Nova Scotia<\/strong><\/a>. (YouTube)
\nRachel Kendall on Nature NS Webinar July 4, 2023.\u201dRachel is currently working as a Research Associate with NSCC Applied Research. She gained professional recognition with her paper on the role of forested wetlands as carbon sinks in southwest Nova Scotia. This research showed that forested wetlands store more carbon in the soil than adjacent upland forests! This is important information to guide decision-making around wetlands and this was the first carbon budget study of forested wetlands in Nova Scotia. In this talk, Rachel will give a background on wetlands in Nova Scotia, explain how she did this research and the results, and highlight studies conducted by other researchers as part of the large collaborative forested wetlands research in Atlantic Canada.\u201d See also: R.
