“…Plant abundance was higher in grassland than in forest, but there was no significant difference between old and new grasslands, although the old grasslands tended to harbour higher abundance in the Sugadaira Highland. In the Kirigamine Highland, browsing by the expanding sika deer ( Cervus nippon ) populations has reduced plant species diversity in recent decades (Uchida et al ., 2020). This effect may explain the lack of difference in plant species abundance between old and new grasslands there.…”

Old grassland is considered one of the most biodiverse terrestrial ecosystems. The habitat temporal continuity may promote the accumulation of host species and symbiont arbuscular mycorrhizal fungi (AMF) diversity and strengthen symbiont interactions. We tested the hypothesis that covariation between AMF and plant communities is stronger in old grasslands. We compared the relationship between AMF and plant communities in forests and in new and old semi-natural grasslands in Japan. DNA was extracted from bulk roots collected at each site and from roots ofMiscanthus sinensisat each grassland site. AMF operational taxonomic unit was characterized on the basis of small subunitrRNAgene sequences. Old grasslands harboured the highest diversity of AMF among vegetation types. The AMF compositions were significantly related to those of plant species. The covariation of plant–AMF communities was stronger in old grasslands than in new grasslands. Individuals ofM. sinensiswere found to share AMF with bulk roots comprising different species. This suggests that AMF form a common mycorrhizal network among several coexisting plants of different species. Increasing AMF diversity in the shared rhizosphere has been proposed to lead to more efficient utilization of soil nutrients and to increase overall benefits of plant–AMF facilitation.

“…The coarse‐filter conservation approach often requires additional management activities for species‐level conservation based on the fine‐filter approach (Hunter, 2005). Although deer fencing, a coarse‐filter approach, is effective for conservation and recovery of plant species richness and flower resources (Uchida et al, 2020), it is insufficient for protecting non‐target endangered and rare plant species unless each individual species is targeted. In contrast, in a case of deer‐overbrowsed grassland in the USA, community‐level deer exclosure and bush removal benefited the population maintenance of a non‐target rare annual plant (Vitt et al, 2009).…”

“…In a sub-alpine, semi-natural grassland on the Kirigamine Plateau, Japan, browsing by sika deer (Cervus nippon Temminck, 1838) has led to catastrophic vegetation damage, and in response, more than 10 deer fences had been built by 2017. Our previous studies showed the positive effects of deer fences on the recovery of plant and pollinator insect species diversity (Nakahama et al, 2020;Uchida et al, 2020). Here, we examined whether deer fences that could recover total plant species richness can also benefit the conservation and recovery of non-target endangered and rare species.…”

“…Even in species‐rich alpine and sub‐alpine grasslands with a variety of endangered species, deer browsing has caused degradation of vulnerable plant communities (Nagaike, 2012; Bernes et al, 2015; Sundqvist et al, 2019). Although little is known about the effectiveness of deer fencing for biodiversity conservation, several recent studies showed its benefits for restoration of plant and insect species diversity in sub‐alpine grasslands (Otsu et al, 2019; Nakahama et al, 2020; Uchida et al, 2020).…”

Questions: Deer-proof fencing is an essential conservation tool to protect and recover plant species diversity in deer-overbrowsed ecosystems, including species-rich sub-alpine grasslands. However, community-level conservation tools (such as fencing) may be insufficient for single-species conservation, particularly for non-target endangered or rare species that are sparsely distributed. We examined whether fencing that can protect and recover total plant species richness also benefits nontarget endangered or rare species. Location: A sub-alpine semi-natural Kirigamine grassland in Nagano Prefecture, Japan. Methods: We conducted two complementary plant surveys (typical vegetation survey using 1-m 2 sampling units and flowering survey using 150-m 2 sampling units) to account for scarce species. We examined the community-level responses (species richness, flowering species richness, and flowering abundance) of all species and endangered or rare species and the species-level responses (occurrence and flowering abundance) of each species to deer fences. Results: Fencing benefited not only the community-level response of all species, but also that of endangered or rare species. As species-level responses, about half of 43 endangered or rare species had greater flowering abundance inside the fences than outside, but only three of them showed a positive effect on their occurrence. These results suggest that once an endangered or rare species has disappeared, it may be difficult to recover. Conclusions: Continued placement of deer fences is necessary to protect community-level plant species richness of sub-alpine endangered and rare species in deeroverbrowsed ecosystems. We also highlight the necessity of additional strategies focusing on non-target individual species across broad areas outside fences.
