“…All factors had correlation coefficients less than 0.7. Transect site was included as a random factor, and the model with the lowest Akaike s information criterion (AIC) was selected for each species (Hamberg et al 2009). All statistical analyses were performed using the software R v 2.11.1 (R Core Development Team, Vienna, Austria).…”

We investigated the environmental factors and tree species characteristics that are important for colonization of an interior-exterior gradient across the forest edge, for application to the restoration of abandoned shifting-cultivation areas in tropical montane forests in the Umphang Wildlife Sanctuar y, nor thwest Thailand. The relative impor tance of physical environment and recruit limitation was evaluated in relation to the regeneration traits of tree species. Three belt transect plots (150 m x 20 m) were established at the transition from secondary forest (edge interior) to open areas (edge exterior) of different ages (1, 3, and 5 years) after abandonment of shifting cultivation. We also set three belts (20 m x 50 m each) in a primary forest remnant. The species composition of canopy trees, regenerated seedlings, and saplings was studied, together with aspects of the physical environment. We found that it was difficult for primary forest species to effectively colonize the forest edge exterior, mostly due to recruitment limitations rather than the physical environment. Many of secondary forest species and generalists were also affected by recruitment limitation (significant negative correlation with the distance from forest edge), though they were also affected by factors related to the physical environment and forest structure and more abundant in open area. Only a few species, like Choerospondias axillaris (primary forest species), Wendlandia tinctoria (secondary forest species), Colona elobata, and Ficus hispida (generalist species) did not suggest recruitment limitation. These results suggested that natural regeneration of secondary forest and generalist species could be utilized as a first step in restoration expecting their facilitation effects for primary forest species.

“…Closed edges with dense vegetation can also increase litter accumulation so as to be similar to the forest interior. Soil fertility and pH had been usually higher at forest edges than that of the interior due to addition of nutrients carried by wind and anthropogenic activities (Hamberg et al, 2009). This could also result from the rapid turnover of litter from fast growing pioneer species including some invasive species.…”

Fragmentation has exposed the Kirigala forest to conditions of the forest and demonstrated its degradation × 5 m gradsects each accommodating 3 pairs of 10 m × 5 m plots, a total of 60 soil samples and 20 seed traps provided annual seed rain of the forest, respectively. Diversity of the edge and the forest interior were compared for the different neighbourhood land use types using the Shannon and Weiner (H) and Simpsons reciprocal (D) indices. Change in the forest in soil pH, soil moisture, nitrogen, available phosphorous and potassium, organic matter content, air temperature, humidity and light intensity between the forest edge and the interior were determined. Soil, microclimate and species richness were combined for clustering of similar areas. The site reported the presence of 55 tree, 12 shrub, 15 herb, 07 climber and 02 vine species including a total of 23 endemic species and 06 invasive species. A higher diversity was observed at the edge, and the highest was observed beside roads as indicated by both diversity indices H and D. Soil and microclimate of the practices. Dominance hierarchy of the trees was Dipterocarpus zeylanicus > Gaertnera vaginans > Aporusa lanceolata, while that for undergrowth/shrubs herbaceous species was Ochlandra stridula > Dracaena thwaitesii > Piper sylvestre. Annual seed rain contained propagules of 23 plant species, while invasive Alstonia macrophylla provided the highest density of seeds. Establishment of foot paths, selective removal of juveniles by root-balling technique and encroachment for crop cultivation have also facilitated the degradation process. It is vital to pay attention on maintaining the ecological stability of this forest before it loses its identity as the Hora Kele of Ingiriya.

“…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). Quando as plantas não conseguem se adaptar às novas condições, há uma alteração na diversidade e composição de espécies (Harper et al 2005, Pütz et al 2011, Tabarelli et al 2012, cuja dimensão irá depender do grau e amplitude do impacto sofrido (Hamberg et al 2009. Estudos feitos por Dupuy & Chazdon (2008), Melo et al (2010) e Dybizinsk & Tilman (2012) demonstraram como essas novas condições ambientais são capazes de interferir no recrutamento de plântulas, propiciando que espécies que antes não ocorriam no local que sofreu impacto, ou eram encontradas em baixas densidades, sejam capazes de ali se estabelecer.…”

-(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
