Mednarodna noč netopirjev – najpogosteje jih ogroža človek

Mednarodna noč netopirjev (MNN) poteka vsako leto zadnji konec tedna v avgustu že od leta 1997. Pri letošnjem, 26. in 27. avgusta, sodeluje že več kot 30 držav.

Mednarodna noč netopirjev ozavešča javnost o biologiji, pomenu in varstvu netopirjev ter njihovih habitatov preko različnih aktivnosti, kot so predavanja, razstave in vodeni sprehodi s poslušanjem ter opazovanjem netopirjev.

Netopirjev je na svetu več kot 1400 vrst in so za glodavci po vrstni pestrosti najbolj pestra skupina sesalcev. So tudi edina vrsta letečih sesalcev. V Evropi živi preko 40 vrst, v Sloveniji pa trenutno 30.

Netopirji imajo pomembno vlogo v vseh ekosistemih

Netopirji imajo pomembno vlogo v vseh ekosistemih, mnogi so žužkojedi in ob prehranjevanju pojedo tudi vrste žuželk, ki so škodljivci na poljščinah ali drugih nasadih, so pomembni rastlinski opraševalci in imajo pomembno vlogo pri obnavljanju tropskih gozdov.

V Sloveniji dogodke ob Mednarodni noči netopirjev, organizira in koordinira Slovensko društvo za preučevanje in varstvo netopirjev. Dogodki potekajo do 15. 9. 2023.

Ogroženost netopirjev

Netopirji so ena bolj najbolj ogroženih živalskih skupin tako v Sloveniji, kot tudi v Evropi in v svetu. Netopirje najpogosteje ogroža človek s svojim poseganjem v prostor, na primer: z uničevanjem netopirskih zatočišč z obnovami stavb, preprečevanjem dostopa v stavbe z zamreženjem odprtin; z nepravilno postavitvijo rešetk na jamskih vhodih in vznemirjanjem na zatočiščih (jamski turizem); z osvetljevanjem preletalnih odprtin na zatočiščih in splošno svetlobnim onesnaževanjem; z uničevanjem in drobljenjem gozdov ali spremembami v gospodarjenju z gozdovi (odstranjevanje starih dreves z dupli, uničevanje prehranjevalnega prostora); s pretirano uporaba pesticidov na kmetijskih površinah.

To function properly, Hotjar stores first-party cookies on your visitor's browser. Cookies are either set by the Hotjar script, or by visiting Hotjar's website. Displaying the correct content to your visitors without personally identifying anyone relies on Hotjar's cookies.

_hjClosedSurveyInvites Hotjar cookie. This cookie is set once a visitor interacts with a Survey invitation modal popup. It is used to ensure that the same invite does not re-appear if it has already been shown. 365 days _hjDonePolls Hotjar cookie. This cookie is set once a visitor completes a poll using the Feedback Poll widget. It is used to ensure that the same poll does not re-appear if it has already been filled in. 365 days _hjMinimizedPolls Hotjar cookie. This cookie is set once a visitor minimizes a Feedback Poll widget. It is used to ensure that the widget stays minimizes when the visitor navigates through your site. 365 days _hjDoneTestersWidgets Hotjar cookie. This cookie is set once a visitor submits their information in the Recruit User Testers widget. It is used to ensure that the same form does not re-appear if it has already been filled in. 365 days _hjIncludedInSample Hotjar cookie. This session cookie is set to let Hotjar know whether that visitor is included in the sample which is used to generate funnels. 365 days _hjShownFeedbackMessage This cookie is set when a visitor minimizes or completes Incoming Feedback. This is done so that the Incoming Feedback will load as minimized immediately if they navigate to another page where it is set to show. 365 days _hjid Hotjar cookie. This cookie is set when the customer first lands on a page with the Hotjar script. It is used to persist the Hotjar User ID, unique to that site on the browser. This ensures that behavior in subsequent visits to the same site will be attributed to the same user ID. 365 days _hjRecordingLastActivity This should be found in sessionStorage (as opposed to cookies). This gets updated when a visitor recording starts and when data is sent through the WebSocket (the visitor performs an action that Hotjar records). Session hjTLDTest When the Hotjar script executes we try to determine the most generic cookie path we should use, instead of the page hostname. This is done so that cookies can be shared across subdomains (where applicable). To determine this, we try to store the _hjTLDTest cookie for different URL substring alternatives until it fails. After this check, the cookie is removed. Session _hjUserAttributesHash User Attributes sent through the Hotjar Identify API are cached for the duration of the session in order to know when an attribute has changed and needs to be updated. Session _hjCachedUserAttributes This cookie stores User Attributes which are sent through the Hotjar Identify API, whenever the user is not in the sample. These attributes will only be saved if the user interacts with a Hotjar Feedback tool. Session _hjLocalStorageTest This cookie is used to check if the Hotjar Tracking Script can use local storage. If it can, a value of 1 is set in this cookie. The data stored in_hjLocalStorageTest has no expiration time, but it is deleted immediately after creating it so the expected storage time is under 100ms. N/A _hjptid This cookie is set for logged in users of Hotjar, who have Admin Team Member permissions. It is used during pricing experiments to show the Admin consistent pricing across the site. Session _hjAbsoluteSessionInProgress The cookie is set so Hotjar can track the beginning of the user's journey for a total session count. It does not contain any identifiable information. 30 minutes
