Geomatics: soil consuming risk in renewable energy plants installation Maurizio Pollino
As indicated in the 2009/28/EC Directive of the European Parliament and Council, ambitious energy and climate change objectives for 2020 have been stated: greenhouse gas emissions reduction for 20%, renewable energy increase for 20%, improvement in energy efficiency for 20%.
Types and "forms" of intervention on the territory, to produce energy from renewables, appear to be multiple and certainly comparable to infrastructure "linear and areal" of anthropogenic nature. It follows that, also for this purpose, the "environment consumption” is one of the main phenomena found at different levels, which add to the already growing soil consumption in our country.
Starting from this consciousness, research of potential and actual impacts, due to the installation for energy production from renewable sources, in a modern land management, must focus on assessing the landscape ecology. A significant problem for some types of plants, mainly those solar and wind power, is the need to install the devices in the environment, with possible negative effects in terms of visual impact and soil consuming. Careful planning to individuate the less invasive and less “visible” plants integration" could reduce the problem, but certainly not eliminate it. It is therefore extremely important to define what weight can have different impacts on the environment, however, considering all possible options.

Understanding and modeling masting in European tree speciesGiorgio Vacchiano
This document summarizes research on modeling and understanding masting in European tree species. It discusses how masting patterns can be reproduced spatially and temporally using context-dependent data to parameterize models. It also examines integrating masting processes mechanistically by relating it to underlying physiological mechanisms like resource accumulation. Challenges include relating seed production to multiple interacting factors and implementing processes not captured in some models. A resource budget model provides the best existing approach, but complete process-based masting models do not exist yet.
This document discusses prescribed burning programs for forest fire management in Italy. It notes that wildfires burn over 112,000 hectares per year in Italy, and climate change is increasing fire frequency and severity. Prescribed burning is used in Italy for several reasons: to regulate rural fire uses, maintain strategic fuel breaks around periodically large wildfires, reduce wildfire risk by increasing forest and plant resilience, and train fire operators. The document describes how prescribed burning plans are implemented and monitored in different regions of Italy, and their effects on reducing fuels and crown mortality in Mediterranean pine forests.
The document discusses the European bioeconomy and forest biomass. It provides background on the EU's Bioeconomy Strategy and Action Plan. Forests play a key role in Europe's circular bioeconomy, providing renewable resources for 25% of the EU's bioeconomy. Forest-based sectors currently employ over 3 million people in the EU.
The document describes the SILVA forest growth simulation model. It discusses trends in forest management, environmental policy, and information technology that created a need for complex simulation models. SILVA is a single tree-based model that simulates individual tree and stand development over time under different treatments and conditions. The model outputs growth, yield, financial, and ecological indicators to support sustainable forest management planning and decision making. The document provides examples of how SILVA has been used for management plans, testing thinning guidelines, economic evaluations, and climate change studies.
A natural stand of Pinus contorta was clearcut and regenerated. It currently has over 7000 trees per hectare. The objectives are to have full site occupancy of over 35% while maintaining vigor with less than 60% occupancy. Precommercial thinning will be conducted to reduce the stand density to 1600 trees per hectare when average diameter is 19 cm, then another thinning will reduce it further to 800 trees per hectare.
This document discusses modeling fire behavior through interactions between fire weather and fuel profiles of forest stand structures. It then provides statistics on an unmanaged Pinus contorta forest that experienced a stand-replacing fire, including stand age, top height, average diameter at breast height, volume, basal area, trees per hectare, relative density, and crown fire indices that indicate an active crown fire would occur.
This document introduces three tree species found in Yellowstone and northern Utah: lodgepole pine (Pinus contorta var. latifolia), Engelmann spruce (Picea engelmannii), and subalpine fir (Abies lasciocarpa). It provides details on lodgepole pine, noting it is adapted to high severity fires, light demanding, produces serotinous cones, and its fire regime varies by location. Engelmann spruce and subalpine fir are typically associated, are shade bearing, and late successional.
This document provides an introduction to modeling forest dynamics. It discusses different types of forest models including tree stand models that operate over 10-50 years and landscape models that operate over 50-100 years. It also summarizes various approaches to modeling including process-based models, empirical growth models, stand models with and without diameter distributions, individual tree models, gap models, and landscape models. The document concludes by discussing tools for visualization of forest modeling results and the aims of a training course on the Forest Vegetation Simulator (FVS) model.
The document describes a stand visualization system that allows users to model tree stands geometrically as a tree list with user-created or FVS output data. The system displays the tree stand with an overhead, profile, and perspective view and stores input data for each tree including species code, plant ID, status, diameter, height, lean angle, end diameter, crown radius, crown ratio, marking status, and X-Y-Elevation coordinates.
FVS is a tree growth and yield model that uses empirical equations to predict tree growth over time including diameter and height growth, crown changes, and mortality. It represents a variety of forest management actions and outputs stand statistics, measures of competition, species composition, economic values, fuel loads, and carbon accounting. Users input tree inventory data, site characteristics, and management prescriptions and FVS simulates forest growth and updates stand statistics over multiple cycles.
1. The document discusses sustainable forest management and outlines several key models and parameters for forest modeling including carbon stocking, wood yield, data availability, and differences between RPF and FVS-NE.
2. It describes a meeting of the Steering Committee where participants were welcomed and an opening of the meeting was provided.
3. Differences between RPF and FVS-NE are discussed and the document suggests what features participants would like to see added to these models.
This document discusses key concepts for designing effective density management regimes for thinning stands of trees, including:
1) Site index - a measure of site quality based on average dominant tree height that can be used to estimate future stand age.
2) Stand dynamics - the different stages of stand development with varying levels of relative density, competition, and site occupancy.
3) Size-density relationships and relative density - ways to quantify current density and desired future condition (DFC) to inform thinning plans. Relative density compares current stand density to the density at full site occupancy.
This document contains instructions and activities for a forest modeling workshop using the Forest Vegetation Simulator (FVS) and Stand Visualization System (SVS). The activities guide participants through simulations of forest stands using FVS, analysis of the output, and visualization of stand conditions over time using SVS. Participants are asked to compare thinning and no-management scenarios, assess stand growth and yield, and customize views of modeled stands in SVS.

cantieri saranno soggetti a monitoraggio a lungo termine, per
valutare l’efficacia degli interventi realizzati sulla stabilità dei
popolamenti forestali, sulla funzione di protezione e la sicurez-
za dei beni da proteggere.
La dimensione degli 8 cantieri sperimentali, compresa tra i 2 e
10 ettari, ha permesso di affrontare il problema della gestio-
ne dei boschi di protezione attraverso una scala di intervento
più ampia rispetto al precedente progetto, nel quale le aree si
imitavano a un solo ettaro. Questo ha permesso di evidenzia-
e come, in boschi di protezione, l’identificazione di più situa-
zioni morfologiche del versante e di più situazioni strutturali
del popolamento impongono una attenta analisi dei singoli
“settori” del cantiere e una loro contestualizzazione all’inter-
no del cantiere stesso. La diversa scala di intervento adottata
ha reso questi cantieri dei casi di studio molto più simili alle
ealtà gestionali presenti sul territorio; questo ha permesso di
analizzare in modo più concreto le problematiche che gli enti
gestori devono affrontare (allestimento del cantiere e gestione
n sicurezza delle diverse fasi, destinazione finale del legname
utilizzato, ecc.).

efficace è la stabilizzazione del manto nevoso attraverso opere di difesa
attiva quali i cavalletti in legno.Tali opere stabilizzano il manto nevoso
sino a una altezza pari a quella della struttura, mentre la loro azione
laterale arriva a 4-5 m verso valle e circa 2 m lungo le curve di livello.
Per tale motivo il loro utilizzo prevede la costruzione di più cavalletti
ravvicinati con una distanza lungo la linea di massima pendenza che var
in funzione di questo parametro (all’aumentare della pendenza si riduce
distanza tra i cavalletti). Nel cantiere in esame sono stati quindi realizzat
all’interno di due canalini di valanga, 25 cavalletti in legno seguendo du
tipologie costruttive diverse. Inoltre, essendo queste opere temporanee,
è necessario realizzare, eventualmente anche in una fase successiva alla
loro costruzione, interventi a favore della rinnovazione, quali la rottura
del cotico erboso, al fine di favorire l’esposizione di suolo minerale; la
creazione di piccoli gradonamenti, al fine di interrompere la morfologia a
elevata pendenza oppure realizzare nuclei di rimboschimento.
Settore 4
La compilazione della scheda di stabilità ha evidenziato il rischio di
una eccessiva semplificazione della struttura sia per strati che per classi
diametriche, anche per la scarsità delle componenti della rinnovazione.
Date però le caratteristiche complessive del cantiere e la limitata superfi
interessata da queste formazioni strutturali, si è ritenuto non necessario
intervenire rimandando a una valutazione futura questa eventualità.

synthetic index of direct protection which is the sum of the
