Eastern Larch

## Identification Eastern larch or tamarack (Larix laricina) is a deciduous conifer with soft needles that turn yellow and fall in autumn. It is native across northern North America and often occurs in cool, moist or wet habitats. It needs full sun and ample space for a mature tree; it is poorly suited to hot, dry or shaded sites. The [US Forest Service profile](https://research.fs.usda.gov/silvics/tamarack) describes its range and habitat. ## Care and placement Match the planting site to its moisture needs and climate, and provide supplemental water where necessary. Allow for its eventual size and falling needles. Monitor for local larch pests and maintain tree health using local extension guidance. ## Firewise source guidance The [Idaho BLM database](https://www.blm.gov/sites/default/files/documents/files/Fire%20Resistance%20of%20Plants%20Master%20Database.pdf) rates eastern larch 4, with a 60-by-20-foot example, full sun, medium water and cold hardiness to zone 2. Its conifer-table guidance calls for pruning lower branches and removing dead needles. The [US Forest Service](https://research.fs.usda.gov/feis/species-reviews/larlar) notes its thin bark and shallow roots make it susceptible to fire damage. Follow local defensible-space and tree-placement guidance; the source score is not a guarantee of survival.
