La primavera ja esclata a les Valls d\u2019\u00c0neu. Despr\u00e9s de mesos de fred i neu, el paisatge es transforma r\u00e0pidament: els marges del riu reverdeixen, els boscos recuperen activitat i les primeres floracions omplen l\u2019entorn de colors i formes ben diverses.<\/p>\n\n\n\n

Avui, durant l\u2019activitat al riu de Son amb l\u2019alumnat de 1r d\u2019ESO de l\u2019Institut Morell\u00f3, hem aprofitat aquest moment de l\u2019any per observar algunes de les esp\u00e8cies que anuncien l\u2019arribada definitiva del bon temps. I entre flors i fulles\u2026 tamb\u00e9 hi hem descobert algun petit habitant ben amagat.<\/p>\n\n\n\n

\ud83c\udf38 Esp\u00e8cies observades durant la sortida<\/strong><\/p>\n\n\n\n

\ud83d\udcf8 V\u00eddua borda (Knautia arvensis<\/em>)<\/strong>
Esp\u00e8cie molt apreciada pels insectes pol\u00b7linitzadors gr\u00e0cies a la gran quantitat de n\u00e8ctar que produeix. Les seves flors poden mantenir-se durant bona part de l\u2019estiu, convertint-se en una important font d\u2019aliment per a papallones i abelles.<\/p>\n\n\n\n

\ud83d\udcf8 Corniol (Aquilegia vulgaris<\/em>)<\/strong>
Probablement una de les flors m\u00e9s espectaculars dels boscos de muntanya. Les seves formes elegants i els esperons de les flors estan adaptats a insectes pol\u00b7linitzadors amb espiritrompa llarga, com alguns borinots.<\/p>\n\n\n\n

\ud83d\udcf8 Herba d\u2019orenetes (Chelidonium majus<\/em>)<\/strong>
Esp\u00e8cie molt coneguda pel l\u00e0tex de color taronja intens que despr\u00e8n quan es trenca la tija. Tradicionalment s\u2019ha utilitzat per tractar berrugues, tot i que tamb\u00e9 \u00e9s una planta t\u00f2xica si no se\u2019n fa un \u00fas adequat.<\/p>\n\n\n\n

\ud83d\udcf8 Lamium maculat (Lamium maculatum<\/em>)<\/strong>
Planta t\u00edpica de zones humides i ombr\u00edvoles, f\u00e0cil de recon\u00e8ixer per les seves flors rosades i les fulles sovint tacades de blanc. Les seves flors atrauen nombrosos insectes pol\u00b7linitzadors. A la fotografia, entre les flors, s\u2019hi amagava un petit visitant sorpresa.<\/p>\n\n\n\n

\ud83d\udcf8 Frare de verneda (Lathraea clandestina<\/em>)<\/strong>
Una de les plantes que m\u00e9s curiositat desperta. No t\u00e9 clorofil\u00b7la i, per tant, no fa la fotos\u00edntesi. Sobreviu parasitant les arrels d\u2019altres plantes, especialment verns i pollancres. El seu color violaci i l\u2019aspecte carn\u00f3s la fan molt caracter\u00edstica.<\/p>\n\n\n\n

\ud83d\udcf8 Roella (Papaver rhoeas<\/em>)<\/strong>
Una de les flors m\u00e9s emblem\u00e0tiques de la primavera. El seu color vermell intens destaca especialment en marges i camps oberts. \u00c9s una esp\u00e8cie pionera que aprofita terrenys remoguts per cr\u00e9ixer r\u00e0pidament.<\/p>\n\n\n\n

\ud83d\udcf8 Llimac negre (Arion ater<\/em>)<\/strong>
Tot i no ser una flor, aquest gran gaster\u00f2pode ha captat l\u2019atenci\u00f3 del grup. S\u2019hi pot observar clarament el pneumostoma, l\u2019orifici respiratori caracter\u00edstic dels llimacs pulmonats. T\u00e9 un paper important en la descomposici\u00f3 de mat\u00e8ria org\u00e0nica al bosc.<\/p>\n\n\n\n

\ud83d\udcf8 Cominassa \u00e0uria (Chaerophyllum aureum<\/em>)<\/strong>
Una umbel\u00b7l\u00edfera pr\u00f2pia de vores de riu, clarianes i prats frescos. Les seves infloresc\u00e8ncies en forma de paraigua s\u00f3n molt importants per a molts insectes pol\u00b7linitzadors, especialment petites mosques i escarabats.<\/p>\n\n\n\n

\ud83d\udcf8 Vinca (Vinca<\/em> sp.)<\/strong>
Planta de flors violetes molt comuna en zones ombr\u00edvoles i marges humits. T\u00e9 una gran capacitat de cobertura del s\u00f2l i sovint forma catifes vegetals molt denses.<\/p>\n\n\n\n

\ud83d\udcf8 Herba de Sant Robert (Geranium robertianum<\/em>)<\/strong>
Petita planta molt comuna en marges i boscos humits. \u00c9s f\u00e0cilment identificable tant per les seves petites flors rosades com per l\u2019olor intensa que desprenen les fulles quan es freguen.<\/p>\n\n\n\n

\ud83c\udf3f La primavera \u00e9s molt m\u00e9s que un paisatge bonic: \u00e9s el moment en qu\u00e8 es reactiven les relacions ecol\u00f2giques. Les plantes floreixen, els insectes pol\u00b7linitzen, augmenta l\u2019activitat dels animals i els ecosistemes recuperen el seu dinamisme despr\u00e9s de l\u2019hivern.<\/p>\n\n\n\n

Sortides com aquesta ens permeten observar aquests canvis de prop i entendre que, darrere de cada flor o de cada petit organisme, s\u2019hi amaguen hist\u00f2ries fascinants i connexions essencials per al funcionament del medi natural. \ud83d\udc9a<\/p>\n","protected":false},"excerpt":{"rendered":"
