No full textUrsus Arctos e promozione territoriale: un approccio di marketing
No full textThe brown bear (Ursus arctos) is a rare species that still survive in the Italian alpine space in Trentino, thanks to “Life Ursus” reintroduction project. The presence of the brown bear is extraordinarily important since only high quality natural environments can host this plantigrade. Nevertheless, the brown bear is potentially a dangerous animal, because it can cause damages to crops and livestock while looking for food. For this reason, some people focus on the cost of hosting the brown bear species in the territory where they live and they protest against its presence. On the other hand, hosting such an endangered species has many advantages too, not only from the ecological point of view, but also connected with a good publicity for tourists. Often, Italian broadcasting companies broadcast reportages about the animal and the BBC have produced a documentary titled “Predators in your backyard”, broadcasted worldwide. These programs create a good publicity to Trentino province and may attract tourists. This contribution offers an Advertising Value Equivalent (AVE) application, through which it is assessed the advertising value of a sample of reportages broadcast in italian newscasts and the BBC documentary, in order to have an overview of what it is the general magnitude of the appearance value of the brown bear in television.
L’orso bruno (Ursus arctos) è una specie in estinzione, che ancora sopravvive nell’arco alpino italiano solo nella provincia autonoma di Trento, grazie al progetto di reintroduzione “Life Ursus”. La presenza dell'orso bruno è straordinariamente importante perché solo ambienti naturali di alta qualità possono ospitare l'animale. Tuttavia, visto che l'orso può avere comportamenti potenzialmente dannosi per gli allevamenti e le coltivazioni, una parte della popolazione residente in provincia non vede di buon occhio l’animale. L’orso però può essere un fattore di attrattiva per i turisti interessati alla natura e alla possibilità di vedere l’animale nel suo ambiente naturale. Anche i telegiornali nazionali sovente trasmettono servizi che parlano dell’orso e che lo ritraggono nel suo habitat. Inoltre, la BBC inglese è andata sul territorio dove vive il plantigrado per trasmettere un documentario dal titolo “Predators in your backyard”, trasmesso poi in molte parti del mondo. Questo interesse da parte del mondo televisivo produce una buona pubblicità per il territorio e può indurre turisti ad andare in vacanza in quelle zone. Partendo da queste considerazioni, il presente lavoro mostra un’applicazione di una tecnica di marketing chiamata Advertising Value Equivalent (AVE), utilizzata per valutare il valore in termini promozionali dei servizi televisivi. In questa sede viene preso in considerazione un campione di servizi televisivi ed il documentario della BBC, al fine di capire in quale ordine di grandezza si possa attestare il valore di queste apparizioni televisive
Advertising value of the brown bear in the Italian Alps
No full textIn Italy, the reintroduction of the brown bear (Ursus arctos) has created conflicts with people because bears may damage livestock, crops, or honey farms. These damages—and their financial costs—are sometimes used as an argument by those who oppose the presence of this carnivore. Despite such damages, bears can provide economic benefits, such as attracting eco-tourists for bear-watching. The Advertising Value Equivalent was used to assess the value of the bears’ appearances in newscasts and documentaries from 2011 to 2015. The marketing value of the bear as a promoter largely exceeds the amount of reimbursements for damages. This method can be used to highlight the economic benefit that the bear can produce for a destination and contribute to complex discussions with managers and stakeholders
Multi-temporal dataset of stand and canopy structural data in temperate and Mediterranean coppice forests
No full textKeymessageWe provided long-term stand and canopy structural data from permanent monitoring plots representative of somemost diffuse temperate and Mediterranean forests, under different coppice management regimes. Periodic inventories wereperformed in the surveyed plots since the 1970s. Annual litterfall production and its partitioning (leaf, woody, reproductiveparts) and optical canopy measurements using the LAI-2000 Plant Canopy Analyzer were performed every year in fully equippedplots since the 1990s. These data can be used for evaluating the influence of coppice management in the stand and canopystructure, the parametrization of radiative transfer models that require accurate ground truth data, and the calibration of high tomedium resolution remotely sensed data.

Modelling the expansion of grey squirrels (Sciurus carolinensis) in Lombardy, northern Italy: implications for squirrel control
No full textNondestructive tree stem and crown volume allometry in hybrid poplar plantations derived from terrestrial laser scanning
No full textAccurate and frequently updated tree volume estimates are required for poplar plantations, which are characterized by fast growth rate and short rotation. In this study, we tested the potential of terrestrial laser scanning (TLS) as a reliable method for developing nondestructive tree volume allometries in poplar plantations. The trial was conducted in Italy, where 4- to 10-year-old hybrid plantations were sampled to develop tree crown volume allometry in leaf-on conditions, tree stem volume, and height-diameter allometries in leaf-off conditions. We tested one-entry models based on diameter and two-entry models based on both diameter and height. Model performance was assessed by residual analysis. Results indicate that TLS can provide accurate models of tree stem and crown volume, with percentage of root-mean-square error of about 20 percent and 15 percent, respectively. The inclusion of height does not bring relevant improvement in the models, so that only diameter can be used to predict tree stem and crown volume. The TLS-measured stem volume estimates agreed with an available formula derived from harvesting. We concluded that TLS is a reliable method for developing nondestructive volume allometries in poplar plantations and holds great potential to enhance conventional tree inventory and monitoring
Modelling the expansion of Sciurus carolinensis (Grey Squirrels) in Lombardy, northern Italy: implications for squirrel control
No full text1) A population of the North American grey squirrel (Sciurus carolinensis), has recently been discovered
in the Ticino Park, Lombardy (N. Italy).
2) We extended Spatially Explicit Population Dynamics Models, successfully used to predict the
spread of grey squirrels in England and Italy, to examine the effects of different control scenarios
on grey squirrel expansion in a 20,000 km2 area around the Ticino Park.
3) Model scenarios were based on the assumption that hair-tube surveys carried out in the past reflect
the actual grey squirrel distribution, which may not be accurate, and underestimate the real distribution
range and current population size.
4) Simulations of grey squirrel spread indicate that, without control, grey squirrels will invade
Switzerland within the next two decades, and that size and distribution of local populations of
native red squirrels will be reduced.
5) Simulation of three different control scenarios suggested that efficient control, removing the alien
species, is possible.
6) The main factor influencing control efficiency is the spatial distribution and total woodland size of
the trapping areas.
7) Immediate actions must be undertaken, as delay in grey squirrel control will result in a population
increase, undermining a successful containment programme.
8) A combination of hair-tube monitoring and a public participation survey to detect grey squirrel
presence is recommended, as well as local co-operation between Italian and Swiss authorities
involved in wildlife management
