“…Additionally, clustering seeds into a single pellet (agglomerative seeding) can provide seedlings enough force to emerge from underneath soil crusts that harden in dry conditions (Madsen et al 2012). Furthermore, large areas are usually reseeded using airplanes or seed drills, which likely do not dispense seeds at the appropriate seeding depth (Rawlins et al 2009). Strategies to aid in bulk seed dispersal while improving seed germination and survival will be critical for effective applications of seed mixes.…”

The worldwide decline in bee populations is threatening the delivery of pollination services, thus leading to the development of pollinator restoration strategies. In the United States, one way to protect and restore bee populations is to use seed mixes composed of pollinator-friendly native plants to revegetate federal lands following disturbance. However, we lack information about which native plant species and mixes are best for bees. We assessed the attractiveness and use by bees of 24 native plant species that are standard for revegetation projects (focal plants) on national forest lands in western Montana. Focal plants that had the highest visitation rate, attracted the most bee species, supported specialist bee species, and bloomed for extended periods across the landscape were considered "pollinator-friendly." Our results suggest that Salix bebbiana, Arctostaphylos uva-ursi, Lupinus sericeus, Rosa woodsii, Symphoricarpos albus, Erigeron speciosus, Symphyotrichum foliaceum, and Gaillardia aristata could create a seed mix that is effective for pollinator restoration on public lands. Pollinator-friendliness score cards are provided to allow land managers to select plant species to include in restoration mixes that benefit pollinators. Identifying mixes of pollinator-friendly native plant species that are available for restoration will allow land managers to both revegetate disturbed habitats and restore bee communities on federal lands. The methods developed in this project can be used to design seed mixes for pollinator restoration on other public lands.

“…While habitat restoration efforts have historically focused on perennial grasses, native forbs are also important to reestablish in ecosystems after a disturbance [1][2][3]. Forbs have value for wildlife and livestock forage, pollinator use, and ecosystem resilience [4][5][6]. The use of these species has historically been limited due to high costs and low success in forcing plants to germinate and emerge [1,3,7].…”

Many plant species exhibit strong seed dormancy. This attribute benefits the species’ long-term survival but can impede restoration when rapid establishment is required. Soaking seeds in gibberellic acid (GA3) can overcome dormancy and increase germination but this treatment may not be effective outside the laboratory. An easier and potentially more effective method to apply this hormone is to coat seeds with a GA3-impregnated polymer. Seed dormancy can also be mitigated by creating a favorable microsite with increased soil moisture. We compared the emergence and establishment of penstemon seeds coated with GA3 to those of uncoated seeds planted in shallow drill rows versus deep, U-shaped furrows. Overall, 6 times more Palmer’s penstemon (Penstemon palmeri; p < 0.01) and 21 times more thickleaf penstemon (P. pachyphyllus; p < 0.001) established when coated with GA3, but GA3 coating did not affect the establishment of firecracker penstemon (P. eatonii; p = 1). Establishment was higher from deep furrows than shallow rows (p < 0.001). These results indicate that GA3 seed coating and deep, U-shaped furrows may improve the restoration success of some native forbs by breaking dormancy and providing a favorable microsite. Land managers could use these techniques to restore native forbs in dry, disturbed areas.
