Aquest dimarts i dimecres 28 i 29 d’abril de 2026 l’alumnat de les classes del Cavall Bernat i Sant Jeroni de l’escola la S\u00ednia<\/a> de Molins ha descobert els secrets del Delta del Llobregat<\/a>. L’alumnat de 4rt de prim\u00e0ria \u00e9s tot un expert en l’an\u00e0lisi de rius i de l’ecosistema del bosc de ribera! Es nota que van aprendre les habilitats dels ec\u00f2legs a la sortida que van realitzar el mes passat a la Riera de Corbera<\/a>! Ara, dins del seu projecte anual de descoberta del Riu Llobregat han caracteritzat el tram m\u00e9s baix del riu! I d’aqu\u00ed unes setmanes aniran al CdA de l’Alt Bergued\u00e0<\/a> a completar l’an\u00e0lisi al seu naixement! Segur que s’emportaran una bona visi\u00f3 del riu en tots els seus trams i d’un dels seus afluents al seu pas per la comarca on viuen! Enhorabona per aquest ambici\u00f3s projecte!<\/p>\n

Han comen\u00e7at fent una valoraci\u00f3 de tots els impactes antr\u00f2pics al voltant d\u2019aquesta zona protegida: l\u2019ampliaci\u00f3 del Port de Barcelona, la depuradora de El Prat de Llobregat, les f\u00e0briques del pol\u00edgon de la Zona Franca i, per descomptat, l\u2019Aeroport Josep Tarradellas Barcelona \u2013 El Prat. Tamb\u00e9 han mesurat la contaminaci\u00f3 ac\u00fastica provocada principalment per avions de passatgers i de mercaderies. Segons els seus c\u00e0lculs, cada dia sobrevolen aquest espai gaireb\u00e9 un miler d\u2019avions!<\/p>\n

Despr\u00e9s d\u2019esmorzar en una zona de p\u00edcnic, han iniciat un recorregut seguint el curs del riu identificant les plantes m\u00e9s caracter\u00edstiques del delta com ara el tamariu, l\u2019\u00e0lber, el cany\u00eds o el jonc. Tamb\u00e9 han reconegut altres plantes com l\u2019esbarzer, la ginesta, el pi pinyoner o l\u2019eucaliptus, i han descobert que la canya \u00e9s una esp\u00e8cie invasora provinent d\u2019\u00c0sia. Finalment, han fet una valoraci\u00f3 de la qualitat ecol\u00f2gica de la vegetaci\u00f3 de ribera seguint el protocol QRISI del\u00a0Projecte Rius.<\/a> \u00c9s important\u00edssim mantenir les zones com a Parcs Naturals! La nostra riba del riu t\u00e9 una qualitat interm\u00e8dia mentre que la de l’altre riba, no protegida pel parc natural, la qualitat del bosc \u00e9s p\u00e8ssima!<\/p>\n\r\n\t

    Amb els binocles han pogut observar xatracs, algun bernat pescaire i flamencs! A continuaci\u00f3 hem extret una mostra d\u2019aigua per analitzar. N\u2019han pogut determinar una s\u00e8rie de par\u00e0metres com la temperatura, la transpar\u00e8ncia, l\u2019olor, la pres\u00e8ncia d\u2019escuma i la seva densitat, d\u2019aproximadament 1,006g\/cm3<\/sup>. Tal com esperaven, sembla que l\u2019aigua analitzada t\u00e9 molta terbolesa a causa del sediment en suspensi\u00f3, la pres\u00e8ncia d\u2019algues i de contaminants, amb una densitat gaireb\u00e9 id\u00e8ntica a l\u2019aigua dol\u00e7a a causa del poc aiguabarreig amb l\u2019aigua marina.<\/p>\n

    Despr\u00e9s han arribat a l\u2019aguait de Cal Tet, on gr\u00e0cies als prism\u00e0tics i a un telescopi ornitol\u00f2gic han seguit observant un munt d\u2019ocells de zones humides: oca comuna, cabuss\u00f3 emplomallat, bernat pescaire, martinet, a m\u00e9s d\u2019algunes gavines. Tamb\u00e9 s\u2019han sorpr\u00e8s amb la pres\u00e8ncia de tres exemplars de tortuga; “la plaqueta”, “la toru” i “la colors”. Eren de l’esp\u00e8cie de la tortuga d\u2019aigua americana de Florida. \u00c9s una esp\u00e8cie ex\u00f2tica i molt abundant als nostres ecosistemes que amena\u00e7a la tortuga end\u00e8mica de rierol per la destrucci\u00f3 del seu h\u00e0bitat. Anem en compte que tamb\u00e9 hem apr\u00e8s d’esp\u00e8cies invasores com la canya que tamb\u00e9 despla\u00e7a el cany\u00eds aut\u00f2cton.<\/p>\n

    L\u2019enhorabona per la vostra gran tasca! Heu estat uns grans exploradors i exploradores plens d\u2019il\u00b7lusi\u00f3 i ganes d\u2019aprendre. Esperem el vostre an\u00e0lisi complert quan torneu de les col\u00f2nies! Som-hi defensors i defensores del riu Llobregat!<\/p>\n","protected":false},"excerpt":{"rendered":"
