Comprehensive biotic surveys, or all taxon biodiversity inventories (ATBI), have traditionally been limited in scale or scope due to the complications surrounding specimen sorting and species identification. To circumvent these issues, several ATBI projects have successfully integrated DNA barcoding into their identification procedures and witnessed acceleration in their surveys and subsequent increase in project scope and scale. The Biodiversity Institute of Ontario partnered with the rare Charitable Research Reserve and delegates of the 6th International Barcode of Life Conference to complete its own rapid, barcode-assisted ATBI of an established land trust in Cambridge, Ontario, Canada.The existing species inventory for the rare Charitable Research Reserve was rapidly expanded by integrating a DNA barcoding workflow with two surveying strategies - a comprehensive sampling scheme over four months, followed by a one-day bioblitz involving international taxonomic experts. The two surveys resulted in 25,287 and 3,502 specimens barcoded, respectively, as well as 127 human observations. This barcoded material, all vouchered at the Biodiversity Institute of Ontario collection, covers 14 phyla, 29 classes, 117 orders, and 531 families of animals, plants, fungi, and lichens. Overall, the ATBI documented 1,102 new species records for the nature reserve, expanding the existing long-term inventory by 49%. In addition, 2,793 distinct Barcode Index Numbers (BINs) were assigned to genus or higher level taxonomy, and represent additional species that will be added once their taxonomy is resolved. For the 3,502 specimens, the collection, sequence analysis, taxonomic assignment, data release and manuscript submission by 100+ co-authors all occurred in less than one week. This demonstrates the speed at which barcode-assisted inventories can be completed and the utility that barcoding provides in minimizing and guiding valuable taxonomic specialist time. The final product is more than a comprehensive biotic inventory - it is also a rich dataset of fine-scale occurrence and sequence data, all archived and cross-linked in the major biodiversity data repositories. This model of rapid generation and dissemination of essential biodiversity data could be followed to conduct regional assessments of biodiversity status and change, and potentially be employed for evaluating progress towards the Aichi Targets of the Strategic Plan for Biodiversity 2011-2020.

The Grand River watershed is the largest in southern Ontario. Poor water quality, floods and drought experienced in the 1930s prompted the formation of the Grand River Conservation Authority. While significant water improvements have been achieved, the Grand River faces chronic stress from the impacts of rapid population growth, land use intensification and changing climate. There is renewed commitment to address evolving water issues through integrated watershed management. This article summarizes the lessons learnt in the Grand River watershed and contends that integrated watershed management, although difficult to implement, provides a useful framework for practical application and positive results. © 2016 Informa UK Limited, trading as Taylor & Francis Group

The Grand River, the largest river in southwestern Ontario, flows 311 km from Dundalk to Lake Erie. To mitigate flooding and low-flow extremes created by the removal of forest cover and wetlands, the Grand River Conservation Authority (GRCA) operates seven multi-purpose reservoirs. The ability to meet future human and ecological water needs depends both on the careful operation of the reservoir network and the protection, rehabilitation and enhancement of hydrologic and ecological functions provided by natural features such as the Waterloo Moraine, the largest moraine within the Grand River watershed. This moraine contains a complex set of stratigraphic and topographic elements, including extensive areas of sand hills and gravel terraces that readily allow precipitation to infiltrate and recharge several overburden aquifer systems. These aquifer systems discharge groundwater to the headwater wetlands and streams and contribute baseflow. This paper presents a watershed perspective of the importance of the Waterloo Moraine to the hydrology, water quality and ecology of the river system and urges the timely uptake of adaptive management and coordinated multi-scale planning (e.g. watershed, subwatershed and municipal) to safeguard the moraine's natural functions. © 2014 Canadian Water Resources Association.
