le foreste dell'australia

LA CONDIZIONE AMBIENTALE :Le foreste australiane variano da pluviali tropicali (umide e calde) a temperate (fresche e umide), con foreste di eucalipti e mangrovie lungo le coste. Sono habitat per specie uniche come koala, casuari e il diavolo della Tasmania. Minacce principali: incendi, deforestazione, cambiamenti climatici e specie invasive.

RUOLO ECOLOGICO:LE FORESTE REGOLANO IL CICLO DELL'ACQUA CATURANO CARBONIO E OFFRONO HABITAT

Biodiversità unica.molte speciedi flora e fauna sono endemichetipo koala e causari

diversità climatica :climi tropicali,temperati e aridi influenzano la vegetazione e la fauna

adattamento agli incendi : gli eucalipti e altre piante sono progettatiper rigenerarsi dopo gli incendi

• CON VEGETAZIONE SPARSA

• FORESTE TEMPERATE:SI TROVANO NELLE

La distribuzione delle foreste australiane varia in base al clima:

LE SPECIE FOCALI

Le foreste australiane sono dominatE da specie chiave come gli eucalipti, che sostengono animali come il koala, e le acacie, importanti per la fauna e la fertilità del suolo. Le casuarine proteggono le coste, mentre i ficus forniscono frutti vitali per diversi animali. Il dingo regola le popolazioni di erbivori, e i cacatua dispersano semi, favorendo la rigenerazione della vegetazione. Queste specie sono fondamentali per la biodiversità e la stabilità degli ecosistemi forestali.

Le foreste australiane sono minacciate da cambiamenti climatici, incendi boschivi, deforestazione, specie invasive, inquinamento e sfruttamento non sostenibile. Questi fattori alterano gli ecosistemi, riducono la biodiversità e compromettono la salute delle foreste.
