En effet, leur fourrure imperm\u00e9able, leur chair et leur glande odorante tr\u00e8s convoit\u00e9e pour la pharmacie et la parfumerie, ont grandement particip\u00e9 \u00e0 la diminution de la population.\u00a0<\/p><p>Heureusement, des groupes ont surv\u00e9cu sur le continent, notamment en France dans le Delta du Rh\u00f4ne.\u00a0<\/p><p>Si les lois fran\u00e7aises et europ\u00e9ennes prot\u00e8gent le castor, son habitat ainsi que les barrages qu&rsquo;ils construisent, les Humains, par leurs actions, sont encore une menace pour lui.\u00a0<\/p><p><span style=\"text-decoration: underline;\">Et maintenant, finissons avec son r\u00f4le d&rsquo;ing\u00e9nieur des rivi\u00e8res,<\/span>\u00a0<\/p><p>Le castor apporte des avantages environnementaux avec sa casquette de\u00a0 garant de la biodiversit\u00e9 des rivi\u00e8res.\u00a0<\/p><p>Et oui ! Notre ami le castor, sait enrichir et diversifier les milieux ainsi que revitaliser les zones humides (r\u00e9servoirs de biodiversit\u00e9) fragilis\u00e9s par l&rsquo;activit\u00e9 humaine.\u00a0<\/p><p>La biodiversit\u00e9 habitant les zones humides sait profiter, voire m\u00eame d\u00e9pend, des actions du castor.\u00a0<\/p><p>En effet, gr\u00e2ce aux barrages (qui n&rsquo;entrave pas la circulation des poissons) offrent un habitat pour des \u00e9cosyst\u00e8mes tels que les loutres, les batraciens, les insectes, les oiseaux&#8230;.\u00a0<\/p><p>De plus, ses constructions de barrages diminuent les p\u00e9riodes d&rsquo;assecs, r\u00e9alimentent en eau les nappes alluviales, r\u00e9duisent de 1\/3 le d\u00e9bit des crues et participent \u00e0 la d\u00e9gradation des pesticides.\u00a0<\/p><p>On peut m\u00eame ajouter que les barrages ont un effet b\u00e9n\u00e9fique contre les incendies.\u00a0<\/p><p>Avec tous ces b\u00e9n\u00e9fices environnementaux, le castor, pr\u00e9sent depuis 10 millions d&rsquo;ann\u00e9es et absent depuis quelques si\u00e8cles, est, sans aucun doute, un acteur favorable \u00e0 la lutte contre le r\u00e9chauffement climatique et ses effets tels que l&rsquo;\u00e9rosion de la biodiversit\u00e9.\u00a0<\/p><p>En Ari\u00e8ge, il \u00e9tait pr\u00e9sent il y a 4\/5 si\u00e8cles entre Ax les Thermes
