El dijous 19 de mar\u00e7 vam viure una jornada inoblidable a la natura. Amb les motxilles posades, ens vam despla\u00e7ar fins a la riera d\u2019Arb\u00facies per convertir-nos en cient\u00edfics per un dia. L\u2019objectiu era clar: determinar la qualitat de l\u2019aigua a partir de l\u2019estudi dels seus habitants m\u00e9s petits: els macroinvertebrats.
\nL\u2019emoci\u00f3 era palpable des del primer moment. Preparades amb salabrets i safates, vam comen\u00e7ar a explorar el fons del riu. La motivaci\u00f3 del grup va ser incre\u00efble; l’esfor\u00e7 de buscar sota les pedres i entre el corrent va tenir recompensa r\u00e0pidament. No es tractava nom\u00e9s de trobar “bestioles”, sin\u00f3 d’entendre qu\u00e8 ens deien sobre l’ecosistema.
\nTrobar macroinvertebrats \u00e9s la millor manera de saber si un riu est\u00e0 sa. El grup va identificar una gran varietat d’esp\u00e8cies:
\n\u2022 Els arquitectes del riu: Vam trobar molts tric\u00f2pters, uns insectes que construeixen la seva pr\u00f2pia casa amb pedretes i sorra. La seva pres\u00e8ncia \u00e9s la prova definitiva que l\u2019aigua \u00e9s de bona qualitat.
\n\u2022 Diversitat animal: Tamb\u00e9 vam observar larves de lib\u00e8l\u00b7lula, escorpins d\u2019aigua, sabaters, heptag\u00e8nids (futures ef\u00edmeres) i larves de t\u00edpula. Tamb\u00e9 vam identificar larves d\u2019escarabat escrib\u00e0 i fins i tot algun amfibi que semblava una sargantana aqu\u00e0tica!
\nConclusi\u00f3: L\u2019aigua d\u2019Arb\u00facies est\u00e0 neta. Quan un riu nom\u00e9s t\u00e9 cucs o cargolets, ens indica contaminaci\u00f3, per\u00f2 la riquesa que vam veure ens confirma la bona salut d\u2019aquest entorn.
\nPer\u00f2 no tot va ser recerca cient\u00edfica. Tamb\u00e9 vam tenir temps per gaudir de l’entorn al parc, on vam compartir un dinar d’entrepans a l\u2019aire lliure. Entre an\u00e8cdotes sobre qui s\u2019havia mullat m\u00e9s i la satisfacci\u00f3 d\u2019haver descobert un m\u00f3n invisible a simple vista, la jornada va ser meravellosa.
\nMarxem amb la roba una mica bruta de fang, per\u00f2 amb la motxilla plena de coneixements i, sobretot, amb la satisfacci\u00f3 d’haver connectat de veritat amb el nostre medi ambient.<\/p>\n

Aqu\u00ed teniu les imatges d’aquell dia!<\/a><\/p>\n
