While sustainable forestry in Europe is characterized by the provision of a multitude forest ecosystem services, there exists no comprehensive study that scrutinizes their sensitivity to management on pan-European scale, so far. We compile scenario runs from regionally tailored growth models and Decision Support Systems (DSS) 20 case studies throughout analyze whether service depends intensity other co-variables, comprising regional affiliation, social environment, tree species composition....
Global Ecosystem Dynamics Investigation (GEDI) satellite mission is expanding the spatial bounds and temporal resolution of large-scale mapping applications. Integrating recent GEDI data into Airborne Laser Scanning (ALS)-derived estimations represents a global opportunity to update extend forest models based on area approaches (ABA) considering dynamics. This study evaluates effect combining ALS-based aboveground biomass (AGB) estimates with GEDI-derived by using temporally coincident...

Europe's forests provide vital habitat for biodiversity and essential ecosystem services whose provision must be sustained or enhanced over the coming century. However, potential to secure increase forest services, while securing requirements of taxa remains unclear, especially within context uncertain climate socio-economic developments. To tease out associated trade-offs synergies, we used ten case study landscapes nine countries throughout Europe. Starting with current status in...
New remote-sensed biomass change products will transform our capacity to monitor and validate large-scale carbon dynamic in the next decade. In this study, we evaluated use of multitemporal Airborne Laser Scanning (ALS) Climate Change Initiative (CCI) BIOMASS spaceborne mission estimate AGB dynamics different Mediterranean forest over an 8-year period (2010–2018). To do so, maps AGB, specifically indirect approach using forest-type specific ALS-based i) countrywide ALS coverage at 25 m...
Wildfires cause substantial environmental and socioeconomic impacts threaten many Spanish forested landscapes. We describe how LiDAR-derived canopy fuel characteristics spatial fire simulation can be integrated with stand metrics to derive models describing behaviour. assessed the potential use of very-low-density airborne LiDAR (light detection ranging) data estimate in south-western Spain Mediterranean forests. Forest type-specific equations were used attributes, namely height, base load,...
The evaluation of forest fuel loading is required by most fire management activities. However, the consideration shrub biomass for planning purposes has been limited inability to predict its growth and accumulation. main objective this study was model over time under a tree canopy be able include in risk mitigation plans. Data purpose obtained from 4th 5th Portuguese National Forest Inventories. Five biologically realistic models were built describe accumulation forests. selected indicates...
Abstract Background Climate change may strongly influence soil erosion risk, namely through variations in the precipitation pattern. Forests contribute to mitigate impacts of climate on and forest managers are thus challenged by need define strategies that protect while addressing demand for other ecosystem services. Our emphasis is development an approach assess impact silvicultural practices management models risks under change. Specifically, we consider annual variation cover-management...
This paper presents a model to predict annual wildfire risk in pure and even-aged eucalypt stands Portugal. Emphasis was developing management-oriented model, i.e., that might both: (a) help assess occurrence probability as function of readily available forest inventory data; (b) the effects management options (e.g., silvicultural treatments) on fire stands. Data from both 1995/1998 2005/2006 Portuguese National Forest Inventories well perimeters' data were used for modeling purposes....
Abstract Background Soil erosion is still identified as the main cause of land degradation worldwide, threatening soil functions and driving several research policy efforts to reverse it. Trees are commonly associated some most successful land-use systems achieve protection goals, but extent which forest ecosystems reduce risks can largely depend on management decisions silvicultural practices. Optimization tools assist foresters in solving complex planning problem they face, concerning...
Assessing impacts of management strategies may allow designing more resistant forests to wildfires. Planning-oriented models predict the effect stand structure and forest composition on mortality for supporting fire-smart decisions, allowing its inclusion in optimization systems were developed. Post-fire was modeled as a function measurable inventory data projections over time 165 pure 76 mixed stands Portugal, collected by 5th National Forest Inventory plots (NFI) plus other sample from...
<ja:p>Forest and fire management planning activities are carried out mostly independently of each other. This paper discusses research aiming at the development methods tools that can be used for enhanced integration forest activities. Specifically, damage models were developed Eucalyptus globulus Labill stands in Portugal. Models based on easily measurable characteristics so managers may predict post-fire mortality structure. For this purpose, biometric data fire-damage descriptors from...
Maritime pine (Pinus pinaster Ait.) is an important conifer from the western Mediterranean Basin extending over 22%of forest area in Portugal. In last three decades nearly 4% of has been burned by wildfires. Yetno wildfire occurrence probability models are available and fire management planning activities thus carriedout mostly independently each other. This paper presents research to address this gap. Specifically, it a modelto assess regular pure stands Emphasis was developinga model based...
In this paper, we present a web-based decision support system (DSS)—wSADfLOR—to facilitate the access of stakeholders to tools that may contribute enhancing forest management planning. The emphasis is on architecture and web graphic user interface (wGUI) effectively analysis trade-offs between ecosystem services in order address participatory sustainable objectives. For purpose, wGUI provides remote information system, enabling users analyze environmental biometric data topological as well....
Estimating forest inventory variables is important in monitoring resources and mitigating climate change. In this respect, managers require flexible, non-destructive methods for estimating volume biomass. High-resolution low-cost remote sensing data are increasingly available to measure three-dimensional (3D) canopy structure model structural attributes. The main objective of study was evaluate compare the individual tree estimates derived from high-density point clouds obtained airborne...
Sustainable forest management needs to address biodiversity conservation concerns. For that purpose, managers need models and indicators may help evaluate the impact of options on under uncertainty climate change scenarios. In this research we explore potential for designing mosaics stand-level objectives a broader landscape-level. Our approach integrates (i) an effective indicator reflect tree species composition, stand age, understory coverage divergent conditions; (ii) linear programming...
Maritime pine (Pinus pinaster Ait) is a very important timber-producing species in Portugal with yield of ∼67.1 million m3 year−1. It covers ∼22.6 per cent the forest area (710.6 × 103 ha). Fire most significant threat to maritime plantations. This paper discusses research aiming at development post-fire mortality models for P. Ait stands that can be used enhanced integration and fire management planning activities. Post-fire was modelled using biometric data from 2005/2006 National Forest...

Climate change is driving worldwide efforts to mitigate and reverse the increasing anthropogenic emissions of greenhouse gases. Forests can uptake considerable amounts carbon from atmosphere, but management decisions resultant silvicultural practices largely influence these ecosystems’ balance. This research presents an approach help land managers cope with need ensure provision forest products services while contributing mitigating climate via sequestration. The emphasis on combining a...
