1 Rare Plant Translocation: Don t Do It! Sarah Vinge-Mazer, Saskatchewan Conservation Data Centre Native Prairie Reclamation and Restoration Workshop 2017

2 Translocation the deliberate transfer of plant material from one area to another Seeds Cuttings Propagated seedlings Plants dug out of the ground

3 Translocation Issues Little knowledge of species requirements and associations

4 Translocation Issues Little knowledge of species requirements and associations Little knowledge of population structure Potential for mixing diverse genotypes outbreeding depression

5 Translocation Issues Little knowledge of species requirements and associations Little knowledge of population structure Potential for mixing diverse genotypes outbreeding depression Negative effects to the recipient site

6 Translocation Issues

7 Translocation Issues Little knowledge of species requirements and associations Little knowledge of population structure Potential for mixing diverse genotypes outbreeding depression Negative effects to the recipient site Movement of disease, other species, genetic material Attribution: By s shepherd schizoform on flickr [CC BY via Wikimedia Commons

11 What is success? Survival, vigor, reproduction

12 What is success? Survival, vigor, reproduction What is being measured? Presence, plant height, flowering, setting seed, germination of seed

13 What is success? Survival, vigor, reproduction What is being measured? Presence, plant height, flowering, setting seed, germination of seed Over what time period? 1, 2, 5, 20 years

14 What is success? Survival, vigor, reproduction What is being measured? Presence, plant height, flowering, setting seed, germination of seed Over what time period? 1, 2, 5, 20 years Comparison to control site?

15 What is success? Survival, vigor, reproduction What is being measured? Presence, plant height, flowering, setting seed, germination of seed Over what time period? 1, 2, 5, 20 years Comparison to control site? How will long term monitoring be ensured?

16 What is success? Survival, vigor, reproduction What is being measured? Presence, plant height, flowering, setting seed, germination of seed Over what time period? 1, 2, 5, 20 years Comparison to control site? How will long term monitoring be ensured? Will management be needed, how will that be provided?

17 The majority of projects fail (if success was even defined). Recent advances in soil science, microbial ecology, and population genetics have in some cases improved the effectiveness of transplantation, but new insights mainly permit a fuller appreciation of the causes of failure.

18 Policy/Legal Info Species At Risk Act Plant translocations for species listed as extirpated, endangered, or threatened under the federal Species at Risk Act (SARA) on Federal lands or Provincial lands where an order is made to have it apply would be prohibited as per Section 32 of SARA. SARA permits may be issued only if the activity meets the criteria under Section 73 of SARA and all reasonable alternatives to the activity have been considered, the activity will not jeopardize the survival or recovery of the species and all feasible measures will be taken to minimize the impact of the activity on the species. SK Ministry of Environment Policy

19 Even when success is defined, even for well planned projects, translocations rarely succeed. Rare plants are best conserved in situ!

20 What can we do instead? Site specific mitigation plans Avoidance! Minimize disturbance Enhance conservation of impacted species/communities through offsets Compensation is a last resort Let s use resources wisely!

21 What about conservation of communities? Conservation of associated species, microsites, ecosystem function Landscape scale planning
