“…In times of human domination of ecosystems of the Earth, their transfer to the new habitat might have occurred directly with human assistance [18,63,64] or indirectly profiting from human infrastructures linking previously unconnected areas [25]. Hence, it becomes increasingly difficult to assess the role of humans in the observed range expansion [65,66], especially if species originate from the same continent or adjacent regions, but human assistance in their transfer cannot be excluded.…”

“…1a-e), assisted migration is a strategy to help them reach more climatically suitable areas (Hoegh-Guldberg et al 2008;Thomas 2011;Schwartz et al 2012;Aitken and Whitlock 2013;Williams and Dumroese 2013). The term 'assisted migration' encompasses both movements within current species ranges-assisted gene flow-as well as assisted colonisation of areas outside of current rangestranslocations (Aitken and Whitlock 2013).…”

“…An extension of assisted migration is to translocate species into novel habitats identified as suitable via modelling approaches (Hoegh-Guldberg et al 2008;Schwartz et al 2012;Williams and Dumroese 2013). This approach could prove particularly valuable in preserving narrowrange endemic species experiencing very rapid climate change and are unable to adapt or migrate quickly enough (Thomas 2011 ; Fig.…”

Constraints to and conservation implications for climate change adaptation in plants

Contemporary climate change is having widespread impacts on plant populations. Understanding how plants respond to this change is essential to our efforts to conserve them. The key climate responses of plant populations can be categorised into one of three types: migration, in situ adaptation, or extirpation. If populations are to avoid extirpation then migration and/or in situ adaptation is essential. In this review we first articulate the current and future constraints of plant populations, but trees in particular, to the different adaptation strategies (e.g. space availability, rate of change, habitat fragmentation, niche availability). Secondly, we assess the use of the most appropriate methods (e.g. natural environmental gradients, genome and transcriptome scans) for assessing and understanding adaptive responses and the capacity to adapt to future challenges. Thirdly, we discuss the best conservation approaches (e.g. assisted migration, biodiversity corridors, ex situ strategies) to help overcome adaptive constraints in plants. Our synthesis of plant, and particularly tree, responses and constraints to climate change adaptation, combined with the identification of conservation strategies designed to overcome constraints, will help deliver effective management actions to assist adaptation in the face of current and future climate change.

“…Such decisions will depend significantly on the perspectives of different segments of society (policymakers, conservationists, the public) about the level of intervention needed to maintain nature for nature's sake or nature deemed valuable for human utility or amenity, and what plant communities constitute naturalized landscapes whether it be native, exotic, or novel compositions where ecological integrity is maintained (Higgs, 2003). Retention or restoration of many historic ecosystems, and/or conserving certain species in their current range may no longer be feasible; however, there are species, sites and scenarios where other options are appropriate (Hoegh-Guldberg et al, 2008).…”

Managed Migration of Coast Redwoods: Subjectivity of Stakeholders in Oregon’s Land Use Planning Community

The Earth's climate is changing at a faster pace than the slow natural adjustment rates of most species to their rapidly shifting habitat conditions, especially for long-lived tree species, such as the iconic coast redwood Sequoia sempersqvirens. This may leave some species stranded in less than optimal environments, resulting in population extinctions and/or the need for human-assisted migration. However, the implementation of assisted migration does not come without economic, legal, political, ecological, and ethical issues. One of the most important and complex social questions regarding assisted migration is that of the land use planning community in the area being considered. This article explores the subjective beliefs among these stakeholders regarding managed migration of coast redwood trees into suitable habitats in Oregon. Q-methodology was used to structure the complexity of participants' subjective beliefs into a few manageable themes to reveal broader socio-economic and environmental perspectives and shared ways of perceiving and valuing the relationship between social, economic, and environmental concerns. The findings of this study suggest two main factors 1) positively ranked values that align on new perspectives of utilitarian ecological values, and 2) positively ranked values that align on a land based communitarian perspective. This convergence suggests an ecologically aware land management ethos as opposed to the view of favoring human's dominion over nature, and therefore bolsters the potential for the future success of managed migration of coast redwoods into suitable habitats in Oregon given the state's existing land use policy.
