IS­-SIĠAR BARRANIN… l­-impatt dirett tagħhom.

Alfred E. Baldacchino

L-­aħħar li tkellimna kien fuq id-­differenza bejn is-­siġar indiġeni Maltin, u s-­siġar li mhumiex indiġeni Maltin. Is­-siġar indiġeni Maltin huma dawk is­-siġar li minn dejjem kienu jikbru f’dawn il­-gżejjer. Dan, b’mod sempliċi, huwa l-­istess bħal mal-­lingwa Maltija hija lingwa indiġena tal­-gżejjer Maltin, u bħalma l­-Ġappuniż huwa lingwa indiġena tal-Ġappun.

Meta tinġab siġra barranija u titħawwel hawn Malta, din jista’ jkollha numru ta’ impatti negattvi fuq il-­biodiverstà Maltija. Dawn nistgħu niġbruhom taħt tlett irjus: dawk ekoloġiċi, dawk soċjali u dawk ekonomiċi. Dawn l­impatti jistgħu jkunu kemm diretti kif ukoll indiretti.

L-­impatt ekoloġiku ma jgħoddx biss għas­-siġar imma jgħodd għal kull speċi li tiddaħħal fl-­ambjent, fl­-ekosistema li ma tkunx naturali tagħha. Din tista’ tiddaħħal bi żball, bil-­ħsieb, jew inkella wara li tinġieb minn barra l-­ambjent mhux tagħha, taħrab u tibda toktor f’dan l-­ambjent natural fejn qatt ma kienet tikber qabel.

U meta din tinfiles f’dan l-­ambjent natural, ma tistax ma tagħmelx impatt li jkollu effett ħazin fuq l­-ekosistema ­ – in-­nisġa naturali tal-post. U hawnhek f’dan il-­każ, insibu siġar mhux indġeni li jew jaħarbu waħedhom billi jxerrdu ż-­żerriegħa, kif spjegajna fl­-ewwel artiklu, jew inkella billi xi ħadd jarmihom fl-­ambjent naturali.

U l-­impatt negattiv ta’ dawn huwa li huma jikkompetu ma’ speċi oħra indiġeni, jikkompetu għall-­art, u għall-­ispazju, jikkompetu għad-­dawl, jikkompetu għall-­ilma li bħalna mingħajru ma jgħaddux. U dawn is­sigar li ddaħħlu minn barra jistgħu jkunu tant b’saħħithom li s­-siġar, il-pjanti u l­-fawna indiġena ma jkunux jistgħu jagħmlu xejn kontrihom. Tant li ma jkun hemmx xejn li jista’ jwaqqafhom u jikkontrollahom.

Uħud minn dawn is­-sigar barranin li jiddaħħu Malta meta jirnexxilhom jaħarbu u jibdew jokbtru mingħajr ma jkunu jistgħu jiġu kkontrollati, jsiru invażivi ­ ikunu qed jinvadu ambjent naturali li mhux tagħhom.

Hemm saħansitra wħud minn dawn is-­siġar li nġabu u ddaħħlu hawn Malta li wara li jaħarbu, u anki jekk ma jaħarbux, huma kapaċi li kemm mill­-weraq tagħhom li jaqgħu taħthom kif ukoll mill-­għeruq tagħhom jagħmlu kimika bijoloġika li ma tħallix speċi oħra jikbru fil­madwar, biex hekk ma jkollhomx kompetizzjoni għas-­saħħa u l­-għixiem tagħhom. Waħda minn dawn is­-siġar hija l­-Ewkalyptus jew kif isibuha xi wħud, is­-siġra tal-­gamiem.

Minbarra hekk, billi huma ma jkunux jiffurmaw parti mill­-ekosistema tal-­post ma jkunx hemm speċi oħra la ta’ fawna u lanqas ta’ mikoorganismi li jattakkawhom u jgħixu fuqhom biex jikkontrollawhom.

Iżda dan huwa biss impatt dirett. Minbarra dan hemm ukoll l-­impatt indirett. Illum kif wieħed jista’ jara, anki f’pajjiżna l­-ġirja għal­konsumiżmu u l­-qligħ tal-­flus f’qasir żmien għelbet kull etifka, rispett u responsabbiltà ekoloġika, soċjali u ekonomika. Jekk hemm il­-qligħ tal-flus, mela mexxi u toqgħodx taħseb fuq l-­impatti li jista’ jkun hemm fil-qrib jew fil-­futur. Dan iħallsuhom il-­poplu u l-­ambejnt.

Jekk wieħed illum idur dawra mal­-pajjiż wieħed jista’ jara numru ta’ siġar kbar li ġurnata ma jkunux hemm u l­-għada Alla jbierek tarahom siġar kbar ta’ aktar minn 10, 12, 20 sena. Dan kif jingħad isir biex isebbħu l­-pajjiż, għalkemm mhux kulħadd jaqbel ma’ dan. U wieħed jista’ jara minn dawn is-­sigar li lanqss biss huma Mediterranji imma migjuba minn kontinenti oħra bħal Asja, l-­Amerika t’Isfel u l-­Affrika. Siġar kbar li jiġu importati fi qsari kbar bl-­għeruq fil-­ħamrija. U magħhom aktar iva milli le, dawn iġibu organiżmu oħra li ma jkunux jidhru u ma jkunux jistgħu jiġu kkontrollati. U meta dawn jitħawlu f’posthom madwar Malta dawn l-­organismi jinfirxu u jagħmlu l-­ħsara lill-­ekoloġija Maltija. Ngħidu aħna bħalma qed jagħmel il-­Bumunqar Aħmar tal­-Plm, fost ħafna oħrajn.

Imma fuq dan nitkellmu fl­-artiklu li jmiss.

  1. Alfred jirnexxilu jispjega bi kliem sempliċi l-effett ta’ siġar barranin fuq l-ekoloġija ta’ dawn il-Gżejjer.

  2. David Carabott says:

    you sound very labour – we cannot see your ”writing on the wall”. it’s such a shame that most of the castille area trees will be uprooted to make place for the monument of that squalid demonic dwarf

    • I am sorry to say Mr Carabott that I just cannot see your point. It seems that you are new to my blog, otherwise you would have easily seen the “writing on the wall”. I am afraid that you cannot see the wood for the trees. People who are monocolour do not usually see it. Furthermore you seem to be quite a staunch partizan political supporter by the tone of your comment. If you can please let me know of your writings in favour of trees and the need for the protection of local bioidversity, I would be very grateful and perhaps I can also give you a helping hand.

      Considering the present Government lack of sensitivity and lack of appreciation of local biodiveristy (which includes trees), similar to that of the previous government, I am not surprised of the fate of the trees at Castille. And I am sorry to say that the tone of your letter is giving this mentlaity a helping hand.

  3. politics has been the demise of all progress in Malta. We seem to depend much on the minister of environment to move on in life. Everything seems to be politicised at the detriment of our progress. Malta as seen from above is totally naked from greenery and lots of trees need be planted everywhere. The environment section should be privatised. If any monument is seen as more important than living trees than we are truly naive. But then again all parties have left their scars over environment. MEPA is badly managed, people are left unsatisfied knowing their taxes are being squandered. No wonder we take holidays and greatly enjoy others progress towards greenery. We keep hoping things will change but we are that change. Complaining will get us nowhere. A collective stand is needed the soonest.
