Invasive alien species (IAS) require management to mitigate their impact on ecosystems. The success of management decisions often depends on whether they are socially acceptable and to what extent people are willing to be actively involved in an early warning and rapid response system (EWRR). We administered a nationwide public poll to assess people's knowledge on plant, insect and fungal IAS; their perception of IAS as an environmental problem; and their support for different IAS management measures. Most respondents (76%) knew the term IAS, and more than half (62%) provided a correct definition. Species with more media attention and those that are easily visible are more frequently identified correctly. Almost all respondents (97%) support an EWRR system; however, there is heterogeneity in terms of the types of actions people approve of. Non-lethal measures garner more support than lethal ones. Gender and previous knowledge also affect the level of agreement. The willingness-to-pay question largely confirmed this, as people were divided into four classes according to their preferences for either biological, mechanical or chemical measures to control IAS; completeness and location of removal; and having an EWRR established. Mechanical removal is the most preferred treatment in two of the four classes, and complete removal is preferred over partial removal in one of the four classes. Having an EWRR is consistently supported in all classes, and removal in urban areas is preferred over removal in forestland in only one class.
PovzetekPripravili smo Opozorilni seznam tujerodnih vrst za gozdove v Sloveniji, ki potencialno predstavljajo nevarnost za naše gozdove. Upoštevali smo glive, rastline, žuželke in sesalce, za katere po našem mnenju obstaja verjetnost, da se bodo v prihodnosti naselile v slovenskih gozdovih in povzročile ekološko in gospodarsko škodo. Pri izboru tujerodnih vrst smo upoštevali naslednje kriterije:1. Habitat vrste vključuje tudi gozdni prostor. 2. Vrsta je v drugih državah s primerljivimi okoljskimi in podnebnimi razmerami že invazivna in jo tako v Sloveniji smatramo kot potencialno invazivno tujerodno vrsto.3. Vrsta se že pojavlja v bližini Slovenije in zanjo obstaja verjetnost, da se razširijo na območje naše države. Pri rastlinah smo upošte-vali tudi tiste vrste, ki so že prisotne v Sloveniji, vendar so njihove populacije majhne in lokalizirane in ocenjujemo, da jih je še mogoče povsem izkoreniti, zato je smiselno aktivno iskanje novih lokacij in hitro odzivanje ob njihovem odkritju.4. Upoštevali smo tudi tiste gozdne vrste, ki so z Izvedbeno uredbo Komisije (EU) 2016/1141 o sprejetju seznama invazivnih tujerodnih vrst, ki zadevajo Unijo, v skladu z Uredbo (EU) št. 1143/2014 Evropskega parlamenta in Sveta vključene na seznam tujerodnih vrst, ki zadevajo Unijo. Za te vrste mora Slovenija skladno z Uredbo (EU) št. 1143/2014 o preprečevanju in obvladovanju vnosa in širjenja invazivnih tujerodnih vrst vzpostaviti zgodnjega obveščanja in hitrega odzivanja. Pri pripravi Opozorilnega seznama tujerodnih vrst smo pregledali relevantno strokovno literaturo in sezname ITV ter od strokovnjakov iz sosednjih držav pridobili aktualne podatke o ITV, ki so prisotne v njihovih državah in za katere obstaja velika verjetnost, da se razširijo v Slovenijo. Opozorilni seznam trenutno vključuje 12 vrst gliv, 51 vrst rastlin, 13 vrst žuželk in 7 vrst sesalcev. Glavne poti vnosov teh skupin ITV od najpomembnejše do najmanj pomembne vključujejo: pobeg iz ujetništva/vrtov, širjenje s transportom blaga, kot slepi potniki in namerna naselitev v naravo. Pobeg iz ujetništva/vrtov je značilen predvsem za rastline in sesalce. Glavne poti vnosov pri glivah in žuželkah so spontano širjenje, kot slepi potniki in širjenje s transportom blaga. UVODInvazivne tujerodne vrste (ITV) v zadnjih nekaj desetletjih predstavljajo enega glavnih globalnih okoljskih problemov, in sicer zaradi njihovega negativnega vpliva na biotsko raznovrstnost, gospodarstvo ter na zdravje ljudi in živali (Vila in sod., 2011). Čeprav obstajajo šte-vilne definicije izraza ITV, je vsem skupno, da so to vrste, ki so na nekem območju prisotne zaradi vpliva člo-veka in s svojo prisotnostjo negativno vplivajo na ekosisteme, gospodarstvo ali na zdravje ljudi in živali (EU, 2014). ITV lahko na različne načine prizadenejo lokalne populacije domorodnih organizmov (Lockwood in sod., 2013).Gozdovi so v primerjavi z drugimi ekosistemi razmeroma dobro odporni na ITV (Alpert in sod., 2000;. Martina, in sod., 2009;. Sanderson, in sod., 2012), vendar pa so v zadnjih nekaj desetletjih podnebne s...
In Slovenia invasive alien species (IAS) have been overlooked for many years. Despite a growing body of evidence about the negative impacts of IAS, little attention has been given to the issue on a policy level. Legislation and institutional support have also been poorly developed. IAS have only been studied by a few experts. Among the general public, even the term ‘alien species’ was virtually unknown until recently. In 2008 the first nation‐wide awareness project on IAS, Project Thuja, was launched. During this project many general awareness raising activities were carried out including a travelling exhibition and a brochure for hobby gardeners. A well‐attended conference on IAS brought together stakeholders from governmental and non‐governmental sectors. In April 2012 a follow up project Thuja 2 started. This was directed to target groups (fishermen, pet keepers, pet shop employees, gardeners), to aim to change their practices and thereby limit further introductions of IAS. A web‐based system to report observations of IAS was also established. Through these activities, alien species have been recognised as a serious threat to biodiversity by various stakeholder groups. However, as the projects were carried out by non‐governmental organisations, making improvements on a policy level was limited to expert proposals. These have not yet been implemented and a national policy on IAS is still to be developed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
