“…Microbial activity level followed the SOM content but the quality of the SOM affected the enzyme activity patterns. Vegetation increased rapidly in the sites covered with forest organic soil and even the establishment of mycorrhizal symbiosis is expected to be enhanced in covered areas (Lunt and Hedger 2003). We suggest that transferring the surface soil humus layer is a useful approach for ensuring the outcome of habitat restoration and complementary habitat creation especially in situations where the source soil areas would otherwise be lost.…”

A landfill site in southern Finland was converted into urban green space by covering it with a layer of fresh forest humus transferred from nearby construction sites. The aim was to develop the 70 m high artificial hill into a recreational area with high biodiversity of flora and fauna. Forest humus was used as a source of organic matter, plant roots, seeds, soil fauna and microorganisms in order to enable rapid regeneration of diverse vegetation and soil biological functions. In this study we report the results of three years of monitoring of soil enzyme activity and plant species compositional patterns. Monthly soil samples were taken each year between June and September from four sites on the hill and from two standing reference forests using three replicate plots. Activities of 10 different enzymes, soil organic matter (SOM) content, moisture, pH and temperature of the surface layer were monitored. Abundances of vascular plant species were surveyed on the same four hill sites between late May and early September, three times a season in 2004 and 2005. Although the addition of organic soil considerably increased soil enzyme activities (per dw), the activities at the covered hill sites were far lower than in the reference forests. Temporal changes and differences between sites were analysed in more detail per soil organic matter (SOM) in order to reveal differences in the quality of SOM. All the sites had a characteristic enzyme activity pattern and two hill sites showed clear temporal changes. The enzyme activities in uncovered topsoil increased, whereas the activities at the covered Middle site decreased, when compared with other sites at the same time. The different trend

“…Such types of soils are usually rich in ECM fungal propagules and hence, by placing it on the surface of the spoil, may serve as a source of symbiotic fungi for the first generation of trees. Organic enrichment of mine spoils with leaf litter was found to stimulate ECM colonization and therefore, facilitate the growth and foliar N concentration of tree seedlings (Lunt & Hedger, 2003). Seedling establishment and root colonization by a diverse community of ECM fungi can also be enhanced significantly by soil subsurface preparation methods (Bauman et al, 2013).…”

“…Therefore, the inoculum potential and the role of ECM fungi in facilitating tree growth in such environments have been extensively studied. The occurrence of ECM fungal propagules in strongly disturbed soils, like young mine spoils and other pure reclamation materials is usually very low (Malajczuk et al, 1994;Lunt & Hedger, 2003;Bois et al, 2005). Fungal propagules can arrive via airborne or animal-dispersed spores or via the vegetative spread of common mycorrhizal networks from adjacent tree stands (if present) (Allen, 1991;Thiet & Boerner, 2007).…”

“…The inoculum potential, ECM root colonization, and host plant growth can be increased significantly by retaining topsoil, which was removed from the site at the beginning of mining, or transported subsequently from other places (Helm & Carling, 1993;Lunt & Hedger, 2003;Bois et al, 2005). Such types of soils are usually rich in ECM fungal propagules and hence, by placing it on the surface of the spoil, may serve as a source of symbiotic fungi for the first generation of trees.…”

Ectomycorrhizal (ECM) fungi and their symbiotic associations with forest trees are among major drivers of key ecosystem functions such as carbon and nitrogen cycling, plant nutrient and water uptake from soil, plant-plant facilitation/competition and diversity regulation via common mycorrhizal networks. Through their functional traits and interactions with both abiotic and biotic environment, they also significantly affect the process of open land colonization by trees as well as vegetation succession coupled with soil and ecosystem development. Here we review the role of ECM fungi in the early primary and secondary succession following major anthropogenic disturbances. Based on the examples of mine spoils and post-agricultural lands, we demonstrate key ecosystem services provided by ECM fungi in the processes of forest restoration. We point out ecological mechanisms and adaptations which underpin ECM fungal community successional interactions, particularly life histories, dispersal, spatial structure, host preferences, and sensitivity to environmental filters. We emphasize the need of better understanding the role of ECM fungi in the forest restoration practice as it seems crucial for afforestation success and biodiversity rehabilitation. Thus, ectomycorrhizal traits should be a prime consideration in afforestation and carbon sequestration polices, sustainable forest management and biodiversity conservation practices.

Land degradation on officially ‘reclaimed’ opencast coal‐mine sites is a widespread problem in South Wales. This project explores methods suitable for use by community volunteers seeking to effect local environmental improvement by restoring geoecological self‐sustainability on lands that are commonly affected by extreme auto‐compaction and low soil nutrient status. This paper describes a formally established 7‐year experiment designed to assess the effect of three alternative tree planting strategies used in the forestation of such lands. These are notch planting (e.g. forestry), pit planting (e.g. parks and gardens) and trench planting (e.g. orchard terraces). The study explores tree survival and growth for two species commonly used in land reclamation contexts: alder [Alnus glutinosa (L.) Gaertn] and Welsh or Durmast Oak [Quercus petraea (Matt.) Liebl]. t‐testing of the results shows that survival and growth rates for both species tend to be significantly better for trench planting than for pit planting than for notch planting. Differences in mortality between pit‐planted and trench‐planted trees become less significant during the experiment while differences in growth increase with time. The conclusion is that providing a loosened, lower density, rooting substrate significantly improves both the growth and the survival rates of trees planted in compacted Welsh surface coal‐mine spoils and that trench planting is more effective than parks and gardens‐style pit planting, which is more effective than forestry‐style notch planting.
