Summary
| Description |
English: Nurse logs are characteristic of old-growth forests. As old trees die and fall to the forest floor they begin to slowly decay. This provides an excellent starting ground for young seedlings (here Tsuga heterophylla) and also retains moisture necessary for species such as Lungless salamanders.
Français : Les troncs-nurserie (Nurse log pour les anglophones) sont caractéristiques des forêts anciennes ou à haute naturalité. Quand les vieux arbres meurent et tombent au dessus du sol de la forêt, ils commencent à se décomposer. Champignons et bactéries transforment peu à peu ce bois souvent couvert d'une couche de mousse, et qui peut être gorgé d'eau (ou significativement humide, même en période sèche grâce à des substances mucilagineuses) et par l'absorption capillaire d'eau mise en réserve dans le bois mort. Il semble que ces troncs morts soient un excellent terrain de départ pour les jeunes plants issus du semis naturel. (ici Tsuga heterophylla) L'humidité conservée par ces troncs est aussi appréciée voire nécessaire pour diverses espèces d'invertébrés (limaces, escargots, insectes, etc.) notamment consommées par des salamandres sans poumons (très sensibles à la dessication). |
