Si certains insectes sont redout\u00e9s du sylviculteur, d\u2019autres sont bien utiles \u00e0 la for\u00eat ! Certes, les ravages que causent certaines esp\u00e8ces ne sont plus \u00e0 documenter. Les insectes ravageurs peuvent en effet s\u2019attaquer \u00e0 toutes les parties de l\u2019arbre : feuilles, rameaux, \u00e9corces, bourgeons, fruits, s\u00e8ve, etc. Ils sont la cause de d\u00e9g\u00e2ts importants surtout s\u2019ils sont exotiques et que la nature n\u2019est pas adapt\u00e9e localement pour contrer leurs effets.<\/p>\n

Cependant, bien des insectes sont de v\u00e9ritables alli\u00e9s du sylviculteur, rendant d\u2019innombrables services \u00e0 la for\u00eat : pollinisation, pr\u00e9dation des ravageurs, d\u00e9composition de la mati\u00e8re organique, nettoyage des cadavres et autres excr\u00e9ments ou encore a\u00e9ration des racines n\u2019en sont que quelques exemples. Sans les insectes et autres organismes du sol, comment pousseraient nos arbres ? Sans pollinisateurs, comment certaines essences se reproduiraient-elles ?<\/p>\n

Plusieurs actions simples peuvent \u00eatre mises en place pour favoriser les insectes en for\u00eat, notamment le maintien de grosses tiges de lierre et la pr\u00e9servation d\u2019arbres porteurs de microhabitats. Le lierre offre le g\u00eete et le couvert \u00e0 de nombreux insectes et oiseaux, alors que le maintien de quelques arbres \u00e0 microhabitats, g\u00e9n\u00e9ralement de faible valeur \u00e9conomique, permet \u00e0 de nombreux insectes d\u2019accomplir leur cycle de vie complet. Un objectif de trois \u00e0 cinq arbres porteurs de microhabitats par hectare est d\u2019ailleurs recommand\u00e9.<\/p>","protected":false},"excerpt":{"rendered":"
