Persistence of restored populations depends on growth, reproduction, dispersal, local adaptation, and a suitable landscape pattern to foster metapopulation dynamics. Although the negative effects of habitat fragmentation on plant population dynamics are well understood, particularly in grasslands, the population traits that control grassland restoration are less known. We reviewed the use of population traits for evaluating grassland restoration success based on 141 publications (1986–2015). The results demonstrated that population demography was relatively well‐assessed but detailed studies providing information on key stages of the life cycle were lacking despite their importance in determining population viability. Vegetative and generative performances have been thoroughly investigated, notably the components of plant fitness, such as reproductive output, while genetic and spatial population structures were largely ignored. More work on the population effects of ecological restoration would be welcomed, particularly with a focus on population genetics. Targeted species were principally common and dominant natives, or invasive plants while rare or threatened species were poorly considered. Evaluation of ecological restoration should be conducted at different scales of ecological complexity, but so far, communities and ecosystems are over represented, and more focus should be directed towards a population approach as population traits are essential indicators of restoration success.

Research infrastructures play a key role in launching a new generation of integrated long-term, geographically distributed observation programmes designed to monitor climate change, better understand its impacts on global ecosystems, and evaluate possible mitigation and adaptation strategies. The pan-European Integrated Carbon Observation System combines carbon and greenhouse gas (GHG; CO2, CH4, N2O, H2O) observations within the atmosphere, terrestrial ecosystems and oceans. High-precision measurements are obtained using standardised methodologies, are centrally processed and openly available in a traceable and verifiable fashion in combination with detailed metadata. The Integrated Carbon Observation System ecosystem station network aims to sample climate and land-cover variability across Europe. In addition to GHG flux measurements, a large set of complementary data (including management practices, vegetation and soil characteristics) is collected to support the interpretation, spatial upscaling and modelling of observed ecosystem carbon and GHG dynamics. The applied sampling design was developed and formulated in protocols by the scientific community, representing a trade-off between an ideal dataset and practical feasibility. The use of open-access, high-quality and multi-level data products by different user communities is crucial for the Integrated Carbon Observation System in order to achieve its scientific potential and societal value.

European pulse production faces a continued loss of cultivated area along with decreasing or stagnant yields. Vicia faba is a traditional legume with high genetic diversity cultivated in a wide range of European climates. Therefore V. faba is promising to identify stable and high yielding genotypes for specific target environments. The Nordic-Baltic region is challenging for legume growing due to short vegetation period and heat/drought stress in continental climates. Within the pan-European Eurolegume project a set of 18 V. faba accessions containing var. minor and major local landraces and modern cultivars of different geographical origin was evaluated in multi-environmental trials. The aim of this study was to identify ideotypes for Northern Europe and reveal key phenotypic traits conferring high yield potential and stability. Four target environmental clusters represented the range of Nordic growing conditions with yield levels from 128 gm−2 to 380 gm−2. Multivariate classification differentiated distinctive groups of var. minor and var. major accessions with few overlapping genotypes, the former having higher average yield, taller structure, more pods per node and longer flowering duration. Late sowing under long-day conditions above 55°N latitudes resulted in early flowering due to short vegetative development (650 °Cd). Extended flowering duration and tall stature were the most important traits conferring high yields. A negative trade-off between yield potential and yield stability was detected, with yield advantages of stress resistant genotypes only in a limited range of low yielding target environments (< 180 gm−2). The highest yielding accessions (Latvian var. minor landrace Bauska and var. major landrace Cēres) represented a favourable combination of yield potential and stability. High temperatures at flowering, within a range of average maximum July temperatures between 20.5–24.5 °C, were identified as most critical environmental variable depressing yield levels between 38.5 (var. major) and 56.2 (var. minor) gm−2 °C−1. It was concluded that Baltic landraces are promising ideotypes, with adapted flowering phenology and morphological structure, for increased V. faba yields in Nordic target environments.
