Encouraging biodiversity on Maritime farms (2011-)
This work is an ongoing area of research and public engagement that began as collaboration with the Nova Scotia Department of Natural Resources (NSDNR), and has become a broader network of parties interested in conservation on private land in Nova Scotia. Funding has come from NSDNR, Environment and Climate Change Canada’s (ECCC) Species at Risk Partnerships on Agricultural Lands (SARPAL), Ducks Unlimited Canada (DUC), Agriculture and Agri-Food Canada (AAFC), Sage Environmental Program and in-kind support from all of these and the NS Department of Agriculture and the Nova Scotia Federation of Agriculture (NSFA). Findings from this work are the subject of numerous educational and extension activities (see sidebar), including via our farmer extension website. There are overlaps also with my SSHRC Insight Development Grant on farm ecosystem service stewardship, particularly related to farm wetlands under climate change and a small SSHRC research development grant on farm fragmentation and habitat.
The first output was a program evaluation of the small Agricultural Biodiversity Conservation (ABC) Program that is a voluntary stewardship program for farmers, delivered by NSDNR as part of their commitment to the Eastern Habitat Joint Venture of the North American Waterfowl Management Plan. We used surveys in 2012 and found that the ABC program was having an impact in some practices, specifically modified harvest and riparian protection (Goodale et al. 2014). Supplementary in situ interviews later that year suggested a strong land ethic in participating farmers, and the value of using the concept of ‘balance’, rather than sacrifice, to encourage voluntary stewardship (Goodale, 2013).
We also implemented a Nuisance Nature survey with DNR and NSFA in 2013, which was sent to a 625 random farmers in each of Nova Scotia and New Brunswick. We sought to understand which species were perceived as a nuisance, in what way, to which commodities, but also whether any cultural services were experienced (e.g. aesthetic enjoyment) and whether – on balance – the farmer would rather have or not have the species. The survey had an typical response for a single mail-out (12%) and the responses were analyzed for NB and NS-specific reports. The drivers of species tolerance differed whether the species was viewed as a threat, rather than simply causing damage (Goodale et al. 2015).
In summer 2015 we implemented a multiple-reminder survey about management on marginal lands in Nova Scotia with EC, DNR and NSFA, which explored how farmers see and use their less productive lands, like woodlands and wetlands, and the implications of that for biodiversity. Included in this survey were questions about ownership fragmentation, to assist us in understanding how farm geography affects habitat provision. It turns out that fragmentation has no impact on how much habitat is present on a farm; farm area is more likely to matter (Sherren and Greenland Smith, in press).
This work has now spun into the applied realm with the SARPAL project, based at the Nova Scotia Federation of Agriculture and project managed by lab alum Simon Greenland-Smith. He has developed an incentive program for the conservation of threatened wood turtles in the province, Wood Turtle Strides, which is being piloted this summer. Mhari Lamarque, MREM 2016, is helping me with program evaluation. We have no evidence from our work thus far that motivational crowding happens with such programs, but papers are in development.

This project supported Kate Goodale’s MES 2013, who worked for 1.5 years after graduation as a full time extension officer and statistical analyst, project-managing BioLOG and the Nuisance Nature survey. Her first post after Dalhousie was as a full-time Coordinator, Don River and Highland Creek Watersheds at Toronto and Region Conservation (TRCA).
Jillian Baker, MREM 2012, collaborated with Kate on an early literature review on biodiversity-friendly farming in Nova Scotia after her graduation.
Simon Greenland-Smith, MES 2014, took over from Kate Goodale as extension officer and post-Mastoral fellow, project-managing BioLOG and the marginal land survey, among other things. undertook a statistical analysis contract in early summer 2016 to generate farm-scale fragmentation metrics and relate them to the presence of habitat and farm management. He went on to be the project manager for Wood Turtle Strides, a SARPAL initiative funded by ECCC and hosted by the Nova Scotia Federation of Agriculture.
Jason Parise, MREM 2015, undertook preliminary spatial analysis on farm fragmentation as a research assistant in the Spring of 2014, when we discovered the difficulty of identifying individual farms from property databases.
Mhari Lamarque, MREM 2016, has joined the team to work on program evaluation of Wood Turtle Strides, as well as exploring motivational crowding from such programs. She has now taken over as the project manager for the Wood Turtle Strides program.
