“…Many large native species such as oak, beech, and ash are vulnerable to pests and diseases, and hence, planting several species in intimate mixtures, managed by halo‐pollarding, may provide high rates of carbon sequestration and add resilience to climate change (Chavardès et al., 2021; Millar et al., 2007). Although good in‐country seed orchards and nurseries can minimise risks, diseases and pests that are already spreading across Europe (Pötzelsberger et al., 2021) have the potential to damage or kill large numbers of trees in forest and urban landscapes. In addition, the threat to native trees from invasive diseases and pests is growing because of climate change, the transport of live trees and wood products, and the expansion of international trade and travel.…”

Many governments have set ambitious targets for tree planting and increased woodland cover as a key part of actions to reach net‐zero carbon emissions by 2050. However, many uncertainties remain concerning how and where to expand tree cover, what species to plant, and how best to manage new plantations. Much contemporary forestry has been based on even‐aged monocultures, largely because of perceived advantages for timber production. However, in order to play a key role in climate change mitigation future forests will have to achieve timber production (and wider ecosystem service provision) alongside resilience to biotic and abiotic challenge. It is therefore crucial that appropriate informed decisions are made with regard to the structure, composition, and planning of future forests, in order to provide sustainable solutions that provide environmental, economic, and health benefits to society. Genetically diverse, mixed, and irregular forests, with their higher biodiversity and niche complementarity, are promising new forest configurations for regulating the water cycle, storing carbon, and delivering other goods and services. In the following discussion, we have used UK information to illustrate the benefits of mixed woodland versus monocultures and highlighted current issues related to government initiatives and policies for current and future forests. However, similar issues and problems are encountered globally.

“…Of course, 2013 was very rich in May-June precipitation, and allowed significant biomass increases for all clones. Still, outcomes may be influenced by the different densities and conditions of 2015, when defoliator attacks were reported [81].…”

In Romania, the productivity of the new clones of hybrid poplar has not been tested in recent years. This case study aims to fill a gap on the productivity map of the new poplar clones, estimating, by biomass measurements, the productivity of two clones (AF2 and AF8) with different planting densities (from 1333 trees·ha−1 to 2667 trees·ha−1). The short-rotation woody crops (SRWCs) were established in homogeneous conditions, in North-East (NE) Romania and the northern part of Suceava County. Using a specifically developed method, biomass production was estimated using destructive methods, with 190 poplar trees being harvested, measured, and weighed to compute the accumulated biomass for each growing season The biomass production of the crops with 1667 trees·ha−1 planting density highlighted significant differences in productivity in favour of the AF2 clone after five growing seasons. The crops shared similar annual growth patterns, and the stem biomass represents approximately 73–80% of the total biomass of the trees. The second research question concerning planting density influence on productivity showed fluctuations of biomass accumulations at different planting densities (1333 trees ha−1, 1667 trees ha−1 and 2667 trees ha−1) for a 5-year rotation. The outcomes emphasized the influence of the annual weather conditions—primarily the rainfall in May–June—on poplar growth, showing that productivity also depends on the genotype, density and biotic disturbances.

“…Despite their potential in phenology (Depauw et al, 2022), few papers have yet explored the use of CS photo observations to track phenological events across large scales (but see Puchałka et al, 2022; Reeb et al, 2022). As CS data collected without guidance may be biased concerning their spatial and temporal distribution (Pötzelsberger et al, 2021; Tiago et al, 2017), it can be difficult for researchers interested in phenology to deal with challenges arising from the use of CS data. Here, we propose a workflow for iPhenology, the use of publicly available photos to track phenological events (following the iEcology definition of Jarić et al, 2020).…”

Citizen science (CS) comprises the participation of nonprofessional volunteers in scientific projects or investigations. During the last decades, CS has enabled data collection at unprecedented scales (Dickinson et al., 2012). Among the different types of data collected by citizen scientists, photo observations are an invaluable but underused source of research data (Depauw et al., 2022). Recently, the collection of photos potentially available for ecological research has strongly increased, mainly due to the use of smartphone applications for species identification, such as iNaturalist (inatu ralist.org), Pl@ntNet (plant net.org) or Flora incognita (Mäder et al., 2021). These applications have become widely popular during the last years with more than 12 million downloads for the abovementioned apps alone.
