“…This was generally a function of opening the typically closed canopy of Mediterranean evergreen sclerophyllus vegetation and competition for light and nutrions. With similar results, Hall & Kuss, (2003) found out that cover and species diversity increased as one moved closer to the trail in eight out of ten cases they studied.…”

“…Similarly, Farrel & Marion (2002) emphasized trail impacts related to visitation. Nepal (2003) examined trail conditions, Nepal & Nepal (2004) and Turton (2005) summerised visitor impacts on trails, whereas Hall & Kuss (1989) and Bhuju & Ohsawa (1998) examined vegetation responses to trail impacts.…”

“…In establishing hiking trails, long narrow openings are created through the forest. However, it is believed that the trail construction and consequent influx of large numbers of visitors can have negative effects on the surrounding habitats and vegetation (Hall & Kuss, 1989;Li et al, 2005;Maciel et al, 2011). Hiking trails through forests are becoming an important element of the infrastructure management of forests because of the increasing development of forest tourism worldwide.…”

Forest hiking trails may influence local microclimate and biodiversity, but the effects on community structure and diversity of epiphytic bryophytes on trees are currently unknown. Epiphytic bryophytes on 82 Abies faxoniana Rehder & Wilson tree trunks (41 along the hiking trail edge and 41 controls in the forest interior) were investigated at four heights from the ground (10, 50, 120, and 180 cm). At each site, air temperature and humidity were monitored for 1 year. The light radiation levels and air temperature were higher, and the canopy leaf area index and air humidity lower at the trail edge, indicating deterioration in microclimate, resulting from the trail establishment. The epiphytic bryophyte species richness, community cover, and mean cover of dendroid and pendent growth forms on trunks were significantly lower at the trail edge than the control site, suggesting that trail construction caused these reductions. One marked effect of the presence of the trail was the increase in some sun-loving species and decrease in shade-tolerant species. Moreover, the trail also slightly influenced species richness and epiphytic bryophyte cover at both community and species population levels along the height gradient. Comprehensive analyses showed that microclimate deterioration was mainly driven by the trail establishment, and that the change in microclimate along the trail, rather than any host traits, played an important role in the declining epiphytic bryophyte community structure and diversity at the trail edge, confirming the initial hypothesis that the presence of a raised boardwalk (hiking trail) indirectly influences epiphytic bryophyte community and diversity by altering the microclimate.Keywords: Biological conservation, Epiphytic bryophytes, Habitat edge, Old-growth forest, Raised boardwalk IntroductionHiking trails are one of the key infrastructure elements in protected areas including forest parks, and are often established with the intention of reducing direct visitor disturbance to the ground vegetation, forest, and environment, especially trampling damage and impaired regeneration (Cole, 1978;Boucher et al., 1991;Li et al., 2005). In establishing hiking trails, long narrow openings are created through the forest. However, it is believed that the trail construction and consequent influx of large numbers of visitors can have negative effects on the surrounding habitats and vegetation (Hall & Kuss, 1989;Li et al., 2005;Maciel et al., 2011). Hiking trails through forests are becoming an important element of the infrastructure management of forests because of the increasing development of forest tourism worldwide. However, the biological effects of such trails have been insufficiently investigated and thus, are still largely unknown. An understanding of the effects of trail formation and visitor activities on biodiversity is essential for conservation managers seeking to minimize human influence on such sites, where large numbers of visitors can negatively affect the biodiversity conservation of forests (Bo...

“…Grande parte do conhecimento sobre os efeitos dessa influência é proveniente da América do Norte, sobretudo dos Estados Unidos (Cole 1978, 1987, Cole & Marion 1988, Hall & Kuss 1989, Olive & Marion 2009, Wimpey & Marion 2010) e, em menor número, da Europa, Ásia e Oceania (Sun & Walsh 1998, Pickering & Hill 2007, Törn et al 2009). Em relação ao Neotrópico, que abriga elevada biodiversidade (e.g., Antonelli & Sanmartín 2011), apenas recentemente iniciaram-se investigações nesse sentido -notadamente a partir de Rodolfo et al (2008a, b), Villagra (2008) Conforme demonstrado em alguns estudos, principalmente os que tratam sobre o efeito de borda, as alterações das condições abióticas do ambiente, como as provocadas pelo desmatamento e abertura de clareiras e trilhas, são capazes de provocar mudanças em comunidades vegetais (Murcia 1995).…”

-(Trails and their ecological role: what have we learned and what are the prospects for restoration of ecosystems?). We aimed at reviewing the ecological role of the trails and inserting this theme into restoration ecology projects. For a comprehensive understanding of this ecological role, we addressed the applicability of trails to Environmental Education (EE) projects and their impacts on vegetation. We showed that trails are suitable places to practice EE programs. On the other hand, we point out a number of potential concerns arising from the use and opening of trails as, for example, soil compaction and changes in the composition, structure, and diversity of adjacent vegetation. Hence, we indicate that trails can be addressed in restoration projects of ecosystems. We conclude by suggesting some questions that can guide future works on trails and vegetation, including their connections with restoration ecology. Keywords: Environmental Education, forest fragmentation, human impacts, soil compaction, species diversity RESUMO -(Trilhas e seu papel ecológico: o que temos aprendido e quais as perspectivas para a restauração de ecossistemas?). Nosso objetivo foi revisar o papel ecológico das trilhas e inserir essa temática nos projetos de restauração ecológica. Para uma compreensão abrangente desse papel ecológico, abordamos tanto as possíveis aplicações das trilhas para projetos de Educação Ambiental (EA) quanto seus impactos sobre a vegetação. Mostramos que as trilhas ecológicas constituem espaços adequados para a prática de programas de EA. Por outro lado, apontamos uma série de potenciais problemas advindos da abertura e utilização de trilhas, como, por exemplo, compactação do solo e alterações na composição, estrutura e diversidade da vegetação adjacente, para então indicarmos que é possível abordar as trilhas nos projetos de restauração de ecossistemas. Concluímos sugerindo algumas perguntas que poderão nortear os futuros trabalhos sobre trilhas e vegetação, incluindo suas conexões com a restauração ecológica. Palavras-chave: compactação do solo, diversidade de espécies, Educação Ambiental, fragmentação florestal, impactos antrópicos
