“…These values are as little as 17% of pairwise population F ST calculated from microsatellites for other natural Banksia populations at a similar spatial scale (He et al ; Merwin et al ), and 6% of the mean pairwise population differentiation among 24 sampled populations from across the 250 km range of B . menziesii when assessed with AFLP markers (Krauss et al ). These genetic results for the restored patches confirm the sourcing of highly diverse local genetic provenance seed that is genetically integrated with the nearest natural remnant, and reflect an application of best practise seed collection principles for restoration that emphasizes multiple source plants from the local genetic provenance (McKay et al ).…”

Ecosystem functionality is an increasingly important objective of ecological restoration. Despite this, a few studies have rigorously assessed reproductive functionality within restored plant populations, and it is largely assumed that pollinators follow restoration of plant communities-"build it and they will come." Here, we applied an ecological genetic approach to determine the impact of spatial separation on mating in Banksia menziesii (Proteaceae), a dominant bird-pollinated species of Banksia woodlands of Western Australia. All plants at three post-mining restored sites (n = 72 [13 years old], n = 21 [8 years old], and n = 20 [9 years old]), as well as a sample from an adjacent natural reference site (n = 42), were genotyped at nine microsatellite loci. Seed set, mating system parameters, realized pollen dispersal through the assignment of paternity to seed, and avian pollinator species composition, abundance and behavior, were assessed. All patches displayed equivalent heterozygosity (H e = 0.53-0.59) and very weak genetic divergence (F ST ≤ 0.01). Seed of plants within restored sites showed complete outcrossing and relatively high seed set, 26% of which were sired by pollen donors located beyond the local patch. Similar abundance and movement of nectar-feeding birds was observed in restored and natural sites, despite lower bird species diversity in the restored site, where a smaller, less aggressive species was dominant. Our results demonstrate the restitution of wide outcrossing in these restored Banksia patches within an active mine-site, and suggest that restored bird-pollinated Banksia populations are resilient to human impacts, due largely to their generalist pollinator requirements and highly-mobile avian pollinators.

Summary1. Ecological restoration of grasslands is increasingly based on regional seeds derived from predefined seed transfer zones. However, the degree and spatial pattern of genetic differentiation among provenances of different seed transfer zones is largely unknown. 2. We assessed the genetic differentiation among eight out of 22 German seed transfer zones for seven common grassland species (Arrhenatherum elatius, Centaurea jacea, Daucus carota, Galium album, Hypochaeris radicata, Knautia arvensis and Lychnis flos-cuculi) using AFLP markers. We analysed genetic population structure with AMOVA and Bayesian cluster analysis and tested for isolation by distance and isolation by environment. 3. In all of the investigated species, almost all pairs of provenances were genetically differentiated. Bayesian cluster analysis revealed species-specific numbers and spatial patterns of gene pools, with between two (Arrhenatherum) and eight clusters (Lychnis). Most investigated seed transfer zones represented a unique gene pool in the majority of the species. 4. We found isolation by distance in four species, isolation by environment, driven by climatic seasonality, in three species, and a lack of both in three species. Thus, the observed genetic differentiation appears to be caused by both neutral and adaptive processes. 5. Synthesis and applications. Our study shows that grassland plants are indeed strongly genetically differentiated across Germany supporting the strategy of seed transfer zones for ecological restoration. Although the predefined seed transfer zones are unlikely to match the exact genetic structure of many species, they serve their purpose by capturing a substantial amount of intraspecific genetic variation across species.

If climate change proceeds as predicted, plant stock well matched under current climate will be growing in sub-optimal conditions. Forest restoration projects should be based on scientific knowledge especially under climate change. Revegetation with native species is identified as a partial solution for many landscape and biodiversity problems linked to restoration. Plant material can be either sourced locally or from more distant locations within the species range. In the recent decades, genetic material for revegetation projects has been quite often collected locally. However, seed sourcing for ecological restoration is a highly complex issue. Plants that are locally adapted now may not be locally adapted in the future. Adaptation strategies resulting from climate change may not always be possible through a simple shift of seed sources along environmental gradients. Restoration by establishing tree populations genetically diverse and appropriate to ecosystem stability has not been frequently evaluated. This review intends to assess the relevant aspects of tree seed sourcing for future restoration projects. We searched peer-reviewed articles dealing with seeds from tree species published during the last two decades, regardless of continents. Keywords: seed germination; native species; plant adaptation; seed genetics. RESUMOSe as alterações climáticas prosseguirem como previsto, as plantas bem adaptadas ao clima atual estarão crescendo sob condições subótimas. Projetos de restauração florestal devem ser baseados no conhecimento científico especifico sob mudanças climáticas. A revegetação com espécies nativas é identificado como uma solução parcial para muitos problemas de paisagem e da biodiversidade ligados à restauração. O material vegetal pode ser selecionado localmente ou em locais mais distantes dentro da ocorrência das espécies. Nas últimas décadas, o material genético para projetos de revegetação foi, muitas vezes, coletado localmente. No entanto, a seleção de sementes de espécies lenhosas para a restauração ecológica é uma questão altamente complexa. As plantas atualmente adaptadas ao local poderão futuramente não se readaptarem. As estratégias de adaptação resultantes das alterações climáticas nem sempre poderão ocorrer através de simples mudança de fontes de sementes ao longo de gradientes ambientais. A restauração através do estabelecimento de populações de espécies lenhosas geneticamente diversas e adequadas à estabilidade do ecossistema não tem sido frequentemente avaliada. Esta revisão pretende discutir aspectos relevantes da seleção de sementes de espécies lenhosas para futuros projetos de restauração. Utilizaram-se manuscritos abordando sementes de espécies arbóreas revisados e publicados nas últimas duas décadas independentemente dos continentes. Palavras-chave: germinação de sementes; espécies nativas; adaptação vegetal; genética de sementes.
