Selected quote: “Local adaptation to historical conditions could increase vulnerability to climate change, even for geographically widespread species.”
Comment: Native plants from local ecotypes are often promoted as the best choice for home gardens. This study, and many others, show that plants locally adapted to historical conditions may be less suitable than non-native or non-local selections in a changed climate.

Selected quote: “These results illustrate that the belief of local adaptation underlying many management and conservation practices, such as using local seed sources for restoration, may not hold for some species. If contemporary adaptational lag is commonplace, we will need new approaches to help alleviate predicted negative consequences of climate warming on natural systems. We present one such approach, “genome-informed assisted gene flow,” which optimally matches individuals to future climates based on genotype–phenotype–environment associations.”

Wildfires and climate change push low-elevation forests across a critical climate threshold for tree regeneration. Proceedings of the National Academy of Sciences, 116(13), 6193-6198. Full Article
Selected quote: “. . . our results demonstrate that climate change combined with high severity fire is leading to increasingly fewer opportunities for seedlings to establish after wildfires and may lead to ecosystem transitions in low-elevation ponderosa pine and Douglas-fir forests across the western United States.”
Comments: Entire ecosystems are transitioning to different states because of climate change. Managed landscapes (e.g. home gardens) can be manipulated to adapt to such changes up to a point. For example, we can use irrigation in dry spells. However, it is prudent to fortify the resilience of home gardens with a diverse palette of plants that are adapted to conditions other than historical norms. In other words, native plants of local ecotypes cannot alone provide the needed diversity.

Selected quotes: “Climate analogues are being used to identify places in Australia and elsewhere with conditions today similar to those predicted for Melbourne in 2090, to help select new species for the collection. Modelling of the natural and cultivated distribution of species will be used to help select suitable growth forms to replace existing species of high value or interest.”

“Cultivars dominate many designed landscapes including public and private gardens. Despite this, relatively little is known about their ability to tolerate the hydrological extremes that are likely to become more frequent in the near future. Our research in both controlled and garden experiment settings found strong evidence to suggest that highly-cultivated taxa of Primula are more susceptible to extreme stress (including both waterlogging and drought). If many cultivated forms of garden/landscape plants prove to have limited tolerance to the effects of climate change (such as more radical oscillations in soil moisture availability), even when maintained in highly-managed landscapes, then the implications are significant. The loss of a high proportion of cultivated plants (and as this paper also implies, less generalist species) from gardens and parks would have an immense impact on the floral diversity of such landscapes, and in terms of public/heritage gardens undermine the viability of many. Thus a key consequence of this research is a call for ornamental plant breeders to give much greater consideration to stress tolerance when breeding and selecting new cultivars.”

Excerpt: “This review demonstrates that there is ample conceptual and empirical evidence to support trees’ energy saving benefits, especially the assertion “urban trees cool houses”, albeit with considerable variation in the magnitude of impacts and with a caution about how to carefully interpret these benefits.”
