Abstract Nature-based solutions for mitigating climate change focus largely on land management to reduce carbon emissions and enhance sequestration. Tree planting, commonly advocated offset, threatens grassland biodiversity may induce positive radiative forcing (warming) by lowering albedo. Before making decisions about land-use changes in grasslands, an understanding of the fine-scale albedo grassy versus woody vegetation is needed. Existing satellite-based products offer global coverage with temporally fine, but spatially coarse, resolution, whereas situ data are sparse. We examined hypotheses that varies seasonally between grass type patches, shrub grazing at patch scale. Using a tripod-mounted albedometer, we quantified seven distinct patches South Africa’s eastern Karoo during early late dormancy growing seasons. Patches included intensely-grazed lawn ( Cynodon dactylon ), grazed less-grazed red tussock Themeda triandra white Eragrostis lehmanniana Pentzia incana ) encroached grass, bare ground. Season influenced all and, additionally, found strong differences same period years due varying rainfall temperature patterns. For grass-dominated were most pronounced dormancy, likely effect inflorescences. Albedo lawns was consistently higher than other except when equally high. no difference either or grass. Shrub-encroached exhibited lower patches. Our findings underscore nuanced relationship albedo, encroachment, proposed afforestation, certain grasses possibly increasing warming potential through reduced As initiatives extend into these patterns essential mitigation conservation.

Clarifying the driving mechanisms of spatial and temporal changes in regulating ecosystem service value (RESV) is an important part realizing goal sustainable development. Existing studies have focused on specific factors, ignoring complex interactions between factors their regional differences. In this regard, RESV its different zones (core area, fringe peripheral area) were explored Poyang Lake Area, China. The results showed that spatially distribution characteristics area > core while lakes influenced provision services, showing per unit was higher gradually declined with increase distance from lakes, presenting decreasing trend area. From 2000 to 2020, study lost 70.5988 billion CNY for RESV, which most affected.

The state of within-stand variation (WSV) in boreal, coniferous production forests and how it is dealt with thinning operations a scarcely researched topic. In the autumn 2018, we surveyed series Norway spruce (Picea abies (L.) Karst) or Scots pine (Pinus sylvestris L.) dominated stands scheduled for first commercial from below.

Thinning reduced standing volume, number, while quadratic mean diameter weighted height remained unaffected. At thinning, guideline increased increasing density height. However, moderate high guidelines only reached plots elevated (>15 m) combination (>2250 N ha-1). Thus, recommended range (12–14 generally exceeded, which may attributed low thinning. This study suggests that sub-optimal regeneration efforts management young can lead across wide attributes, likely reductions yield. decreased volume however, heavily thinned such degree could potentially cause losses.

In the climate-vulnerable Mediterranean basin, severity and frequency of disturbances such as windthrows, droughts fires are intensifying. Forests generally resilient, but struggle to adapt abrupt changes, which can impact their functionality service provision. Various forest management alternatives aim reduce vulnerability disturbances, few studies have evaluated on multiple provision simultaneously. We aimed at filling this gap by conducting simulations dynamics between 2020 2100 for 261 pine-dominated plots in Catalonia (NE Spain), under two emissions scenarios (RCP4.5 RCP8.5) four (business-as-usual, promotion bioenergy, maximum carbon storage, ecohydrological management). used annual simulated output structure composition future climatic projections produce estimates six ecosystem services, we determined potential forests three main abiotic region: fire, droughts, windstorms. also trade-offs synergies disturbance services. Our predicted a greater influence over climate scenario caused all disturbances. The business-as-usual consistently higher impacts than other scenarios, regardless considered or (fire 175% higher, drought 300%; wind 130%). showed similar patterns impact, differences among them increased more severe conditions. general, there was positive correlation agents, particularly fire (Pearson's r = 0.69). observed that some services is highly correlated impacts, suggesting that, certain schemes, may be compromised due impacts. work supports need an "adaptation-first" model adaptation placed core only way ensure persistence delivery

Drought can impact forests directly causing a decrease of growth, but also increase the vulnerability trees to secondary pests and pathogens, additional loss volume production. To develop new silvicultural strategies, it is crucial understand if thinning promote resilience remaining drought by enhancing an efficient use resources. Given projected drier vegetation periods in Southern Sweden, aim study was determine how tree growth affected severe summer droughts under different regimes. We used experiment established 1991 40-year-old pure oak (Quercus robur L.) stand with two intensities unthinned control. collected cores before after specific events occurring treatment. observed that heavy intensity increased resistance, decreased recovery time reduction when since last intervention 4–5 years. Our results suggest frequent interventions would be appropriate management alternative alleviate stress stands close northern edge their distribution.
