“…Hence, AMF are important since they can significantly improve tree seedlings field survival and establishment. Pouyu-Rojas and Siqueira (2000) , Habte et al (2001) , Ouahmane et al (2006) , Dag et al (2009) , Kapulnik et al (2010) , Karthikeyan and Krishnakumar (2012) , and Manaut et al (2015) have demonstrated the positive effect AMF have in these regards. Pouyu-Rojas and Siqueira (2000) investigated the AMF effect on seven tree species seedlings survival and establishment on degraded pot soils.…”

“…They found out that AMF inoculation in the nursery or during transplanting have equally significantly positive effect on trees survival and establishment. Later on Habte et al (2001) determined the effect AMF nursery inoculation has on field establishment of Acacia koa and accordingly, AMF was shown to improve transplanted tree seedlings growth and establishment by increasing seedlings P nutrition. The role of native AMF inoculation was also demonstrated to have a significant positive effect on the field survival and establishment of Cupressus atlantica Gaussen seedlings on a degraded Moroccan field site ( Ouahmane et al, 2006 ).…”

“…The external hyphae network (extraradical mycelium) of the fungi permeate in to the microsites of rocks and soils surrounding the plant roots ( Finlay, 2008 ; Barea et al, 2011 ) increasing the root absorbing surface area 100 or even 1000 fold ( Larcher, 1995 ). Therefore, AMF increase plants’ nutrient and water relation (e.g., Birhane et al, 2012 , 2015 ; Banerjee et al, 2013 ), and can improve plants’ field survival and establishment (e.g., Pouyu-Rojas and Siqueira, 2000 ; Habte et al, 2001 ; Ouahmane et al, 2006 ; Dag et al, 2009 ; Kapulnik et al, 2010 ; Karthikeyan and Krishnakumar, 2012 ; Manaut et al, 2015 ). AMF improve soil structure, soil water relation, plants’ tolerance to biotic and abiotic stresses, increase plants’ nutrient supply, plants’ growth, yield and reproductive success and reduce fertilizer requirement ( Finlay, 2008 ; Gianinazzi et al, 2010 ; Simard and Austin, 2010 ; Barea et al, 2011 ; Al-Karaki, 2013 ; Soka and Ritchie, 2014 ).…”

The Potential Role of Arbuscular Mycorrhizal Fungi in the Restoration of Degraded Lands

Experiences worldwide reveal that degraded lands restoration projects achieve little success or fail. Hence, understanding the underlying causes and accordingly, devising appropriate restoration mechanisms is crucial. In doing so, the ever-increasing aspiration and global commitments in degraded lands restoration could be realized. Here we explain that arbuscular mycorrhizal fungi (AMF) biotechnology is a potential mechanism to significantly improve the restoration success of degraded lands. There are abundant scientific evidences to demonstrate that AMF significantly improve soil attributes, increase above and belowground biodiversity, significantly improve tree/shrub seedlings survival, growth and establishment on moisture and nutrient stressed soils. AMF have also been shown to drive plant succession and may prevent invasion by alien species. The very few conditions where infective AMF are low in abundance and diversity is when the soil erodes, is disturbed and is devoid of vegetation cover. These are all common features of degraded lands. Meanwhile, degraded lands harbor low levels of infective AMF abundance and diversity. Therefore, the successful restoration of infective AMF can potentially improve the restoration success of degraded lands. Better AMF inoculation effects result when inocula are composed of native fungi instead of exotics, early seral instead of late seral fungi, and are consortia instead of few or single species. Future research efforts should focus on AMF effect on plant community primary productivity and plant competition. Further investigation focusing on forest ecosystems, and carried out at the field condition is highly recommended. Devising cheap and ethically widely accepted inocula production methods and better ways of AMF in situ management for effective restoration of degraded lands will also remain to be important research areas.

“…Because sites can vary in their AM fungal inoculum potential, to rule out any false negatives among the target species due to a lack of AM fungi at a given site, we also collected roots from one Acacia koa plant at each site. This species is known to be dependent upon AM fungal associations (Miyasaka et al, 1993; Habte et al, 2001); therefore, the absence of mycorrhiza in situ would indicate a lack of AM fungal inoculum rather than be evidence of a nonmycorrhizal host among our target species. Sampled roots were stored for up to 3 days at 4°C before being processed for staining.…”

“…Numerous studies have shown that greenhouse inoculation with local AM fungi can improve plant performance in restoration projects (Maltz and Treseder, 2015). Although three greenhouse studies have examined the effects of AM fungi on six native Hawaiian plant species, and all have shown that inoculation leads to a significant increase in plant performance in terms of biomass (Gemma et al, 2002; Miyasaka et al, 1993) and phosphorus uptake (Habte et al, 2001), the fate of these inoculated versus uninoculated plants has not been monitored under field conditions. Furthermore, while the symbiosis between plants and AM fungi is important for plant health and fairly common, there have been very few reports on the mycorrhizal status of Hawaii's native plant species.…”

Premise Prior efforts have shown that continents harbor a greater proportion of mycorrhizal hosts than on islands. However, in the Hawaiian Islands, estimates of the proportion of mycorrhizal plant species are higher than on continents (>90%), but there are few studies to support this claim. Concurrently, Hawaii's flora faces some of the greatest global risks of extinction, and significant efforts are aimed at restoring native vegetation. Arbuscular mycorrhizal (AM) fungi have been shown to improve plant restoration success, but little work has been done in Hawaii to understand the extent of mycorrhizal associations among native plant populations. Methods We surveyed 35 native Hawaiian plant species in the wild, focusing on plant species that are reared for reintroduction. Roots from wild individuals were collected from 10 sites on Oahu to determine degree of mycorrhizal fungal colonization and how this varies across host populations. Results Of the species surveyed, 97% had evidence of mycorrhizal colonization, including 25 endemic and nine indigenous species from 23 families. The mycorrhizal status of 22 of the species surveyed was unknown before this study. For four species, the degree of colonization by AM fungi differed among sites, and these differences corresponded with variations in precipitation and temperature. Conclusions The high incidence of mycorrhizal colonization provides evidence that island flora can actually harbor more mycorrhizal hosts than species on mainlands and that future reintroduction projects should consider the potentially important roles of AM fungi for success of these hosts in the wild.
