Durant els mesos d\u2019abril i maig els alumnes de 3r ESO C de l\u2019institut ens hem dedicat a millorar l\u2019ecosistema del riu Ter a l\u2019assignatura de Projecte Cooperatiu, amb l\u2019ajuda de la Fundaci\u00f3 Emys, una entitat ambiental que treballa per la conservaci\u00f3 del patrimoni natural de la comarca; el seu objectiu \u00e9s la conservaci\u00f3 de la natura i, en especial, de les zones humides i de la Tortuga d\u2019estany (<\/span>Emys orbicularis)<\/span><\/i>.\u00a0<\/span><\/i><\/p>\n

Primer vam fer unes quantes sessions a la classe per decidir i planificar l\u2019acci\u00f3 de millora, i quan ho vam tenir tot a punt vam anar 3 dies a l\u2019espai escollit: la vora del riu Ter.\u00a0<\/span><\/p>\n

El riu Ter forma part d\u2019un ecosistema fluvial i el bosc de ribera \u00e9s molt important per al seu funcionament. Els boscos de ribera s\u00f3n boscos caducifolis que creixen al voltant del riu, i en destaquen esp\u00e8cies aut\u00f2ctones d\u2019arbres com l\u2019Om (<\/span>Ulmus minor<\/span><\/i>), el vern (<\/span>A<\/span><\/i>lnus glutinosa)<\/span><\/i>, el salze blanc (<\/span>Salix alba<\/span><\/i>), el saulic (<\/span>Salix purpurea)<\/span><\/i> o el freixe de fulla gran (<\/span>Fraxinus excelsior<\/span><\/i>).\u00a0<\/span><\/p>\n

L\u2019acci\u00f3 va consistir a eliminar el m\u00e0xim de plantes invasores i recollir brossa del terra. Ho vam dur a terme amb grups cooperatius i vam treure les seg\u00fcents plantes: Canya Americana (<\/span>Arundo donax<\/span><\/i>), Bamb\u00fa groc (<\/span>Phyllostachys aurea<\/span><\/i>), Budleia <\/span>(Buddleja davidii<\/span><\/i>) i Miragu\u00e0 de jard\u00ed (<\/span>Araujia sericifera<\/span><\/i>). Les eines que vam fer servir per eliminar aquestes plantes, van ser: tisores de podar, guants, aixades i fal\u00e7. Seguidament amb aquestes plantes, vam escollir les canyes que estaven en bon estat per portar-les a l’institut i poder-les aprofitar per al nostre hort. Quan acab\u00e0vem de fer l\u2019acci\u00f3 deix\u00e0vem les restes apartades i l\u2019ajuntament les anava a recollir.\u00a0<\/span><\/p>\n

L\u2019eliminaci\u00f3 completa d\u2019aquestes plantes invasores \u00e9s diferent segons cada esp\u00e8cie. Per exemple, per la canya americana s\u2019ha de fer un seguiment durant varis anys perqu\u00e8 no torni a cr\u00e9ixer, ja que el seu rizoma \u00e9s una tija subterr\u00e0nia molt resistent i dif\u00edcil d\u2019extreure; l\u2019ideal seria que cada any an\u00e9ssim a eliminar les canyes, fins que el rizoma es debilit\u00e9s per complet. Per altra banda, per al miragu\u00e0 de jard\u00ed \u00e9s molt important recollir tots els fruits que ens sigui possible, i per la buddleia \u00e9s necessari treure-la d\u2019arrel perqu\u00e8 pot rebrotar. La problem\u00e0tica de les plantes invasores \u00e9s molt important perqu\u00e8 produeixen una disminuci\u00f3 de la diversitat local, competeixen amb les esp\u00e8cies aut\u00f2ctones, les desplacen, i generen desequilibris en l’ecosistema que poden arribar a ser molt greus. Recomanem la p\u00e0gina d\u2019Exocat per a qui vulgui saber m\u00e9s, i el joc online de parelles ex\u00f2tiques.<\/span><\/p>\n

Nosaltres hem pensat que ha estat un bon projecte per comprendre com les plantes invasores estan envaint els nostres ecosistemes, i generant impactes greus a les plantes del nostre territori. Tamb\u00e9 per ser conscients de les escombraries que arriba a haver-hi en entorns naturals per responsabilitat de les persones que van a passejar i llencen la brossa a terra, i sensibilitzar-nos davant aquest problema. I sobretot per fer una cosa \u00fatil per al nostre entorn natural.<\/span><\/p>\n
