“…Oil sands sites reclaimed using forest floor material (vs. peat-mineral mix) had higher cover of trees, shrubs, and forbs, and the soil microbial community composition was converging more quickly towards that of natural upland forest (Hahn and Quideau 2013). Plant propagules in forest floor material lose their viability quickly if the material is stockpiled prior to placement but direct placement of forest floor material can overcome this problem and has shown promise in trials in several different locations (Holmes 2001;Iverson and Wali 1982;Koch et al 1996;Rokich et al 2000;Tacey and Glossop 1980). For example, direct placement of forest floor material on a coal mine reclamation site in Alberta resulted in rapid (B3 year) establishment of 65 native species, 30 of which were characteristic of mature, closed boreal forest (Macdonald et al 2015).…”

Many forested landscapes around the world are severely altered during mining for their rich mineral and energy reserves. Herein we provide an overview of the challenges inherent in efforts to restore mined landscapes to functioning forest ecosystems and present a synthesis of recent progress using examples from North America, Europe and Australia. We end with recommendations for further elaboration of the Forestry Reclamation Approach emphasizing: (1) Landform reconstruction modelled on natural systems and creation of topographic heterogeneity at a variety of scales; (2) Use and placement of overburden, capping materials and organic amendments to facilitate soil development processes and create a suitable rooting medium for trees; (3) Alignment of landform, topography, overburden, soil and tree species to create a diversity of target ecosystem types; (4) Combining optimization of stock type and planting techniques with early planting of a diversity of tree species; (5) Encouraging natural regeneration as much as possible; (6) Utilizing direct placement of forest floor material combined with seeding of native species to rapidly re-establish native forest understory vegetation; (7) Selective ongoing management to encourage development along the desired successional trajectory.

“…Beauchamp et al (1975) found that additional seed was required to meet reclamation requirements when topsoil was used in Wyoming, Application of topsoils on mined lands after their removal from other locations resulted in higher components of native species in the resulting plant communities than when standard seed mixes were used. Iverson and Wali (1982) reported that seed banks are important in introducing some native species to reclaimed lands in North Dakota. They placed a higher importance on innnigrant species, however.…”

Abstract. Three pioneer conununities, a mix of commonly used reclamation species, a community from a forest soil.seed bank, and a mixed community of reclamation species plus seed bank species were established on surface-mine spoils in microplots. A total of 84 taxa originated from the soil seed bank, including five tree species. Adding the reclamation species to the seed bank soil resulted in signific~tly fewer established native species, including tree seedlings in the resulting conununity; many native species were stunted or phenologically delayed. The seed bank community produced more aboveground biomass and sequestered more N, P, K, Ca, and Mg in vegetation than in the other two communities. Speed of ground cover development ranked reclamation mix> reclamation mix plus seed bank > seed bank, but amounts of cover were not significantly different 16 weeks after the study was.established. Differential effects of pioneer communities on ecosystem development on surface-mined lands and use of soil seed banks in their establishment are discussed.

“…Bluegrass is an exception to most perennial grasses because it forms substantial reserves of viable seed (Chippindale and Milton 1934, Champness and Morris 1948, Jalloq 1975, Roberts 1981. Of course, grazing can also affect seed bank composition (Major and Pyott 1966, Jalloq 1975, Iverson and Wali 1982, Kinucan and Smeins 1992, Bertiller 1992 especially if defoliation interrupts sexual reproduction.…”
