Native Plant Species

For East Cascades Oak Habitat Restoration

Balsamroot

Recommended plant species

ECOP’s Native Plant Materials working group has collated a list of priority grass and forb species for restoration in East Cascades oak habitats. The list below is a starting point—review your Ecological Site Description for your site and consult with experts to further refine your desired seed mix.

If you have questions about the species on this list, others you’d like to suggest, or to request the table as an Excel file, reach out to oaks@ColumbiaLandTrust.org.

In the section below, you can learn more about a few of the widespread and often dominant species listed in the recommended oak understory plant species list.

Grasses and Sedges:

Perennial grasses and sedges are a critical part of the oak understory with deep roots that stabilize soils, a clumpy growth that is more fire resistant than invasive annual grasses, and nutritious aboveground leaves and stems that provide forage for wildlife. Here are some of the more common and widespread native species:

  • Alaska brome (Bromus sitchensis)
  • Blue wildrye (Elymus glaucus)
  • Bluebunch wheatgrass (Pseudoroegneria spicata)
  • Bottlebrush squirreltail (Elymus elymoides)
  • Geyer’s sedge (Carex geyeri)
  • Idaho fescue (Festuca idahoensis)
  • Lemmon's needlegrass (Achnatherum lemmonii)
  • Pinegrass (Calamagrostis rubescens)
  • Prairie junegrass (Koeleria macrantha)
  • Sandberg’s bluegrass (Poa secunda)

Forbs:

  • There are many species of balsamroot, but this is a common wildflower on sunny slopes throughout the East Cascades and offers many benefits. It takes years to bloom, but they are well worth the investment!

  • There are several native species of native buckwheat. Arrowleaf buckwheat, tall woolly buckwheat, or snow buckwheat (E. compositum, E. elatum, E. niveum) are some of the more common species.

  • There are many species of lomatium in our area and even an endemic species to the Columbia River Gorge, Lomatium columbianum. Barestem desert parsley (L. nudicaule) and narrowfruit biscuitroot (L. triternatum- recently renamed to L. brevifoloium in our area) are some of the most common species.

  • Lupines produced beautiful, showy spikes of flowers. They have nitrogen-fixing roots and attract a variety of pollinators.

  • A drought tolerant and pollinator-friendly plant. It provides nectar later in the summer when many other plants have finished blooming.

  • This is a culturally important plant that grows in seasonally wet meadow habitats. Camas is also important for wildlife and pollinators.

  • This yellow flowered plant likes well-drained soils, is pollinator-friendly, and spreads rapidly once established.

  • Considered a ‘work horse’ species because it establishes quickly and easily. It is widespread in our region and adapted to most habitats.

Pro Tip

Grass seed is generally cheaper than forb seed, but don’t forget to include forbs in your mix to hit your goals of increasing biodiversity and providing resources for pollinators!

Planting oaks

Oregon white oak is drought tolerant, fire resilient, pollinator friendly, and provides wildlife forage, making it a great species to include in your planting. We recommend planting acorns collected from your site or from a nearby area that experiences similar conditions. It is possible to transplant oak seedlings; however, their long tap root makes transplanting them less successful than many other species. See ECOP’s Acorn Planting Guide for specific instructions.
