“…Long-term land-use legacies on soil physical and chemical properties have been widely documented [61,62] and can lead to altered plant successional trajectories for years after the abandonment of disturbance [63][64][65][66]. There is some evidence that changes in microbial communities may mediate the altered biogeochemical processes in historically disturbed soils [67,68], although the focus of land-use legacies has been on soil properties, while less research has elucidated the historical imprints on microbial communities themselves [68,69].…”

Responses of Soil Fungi to Logging and Oil Palm Agriculture in Southeast Asian Tropical Forests

Human land use alters soil microbial composition and function in a variety of systems, although few comparable studies have been done in tropical forests and tropical agricultural production areas. Logging and the expansion of oil palm agriculture are two of the most significant drivers of tropical deforestation, and the latter is most prevalent in Southeast Asia. The aim of this study was to compare soil fungal communities from three sites in Malaysia that represent three of the most dominant land-use types in the Southeast Asia tropics: a primary forest, a regenerating forest that had been selectively logged 50 years previously, and a 25-year-old oil palm plantation. Soil cores were collected from three replicate plots at each site, and fungal communities were sequenced using the Illumina platform. Extracellular enzyme assays were assessed as a proxy for soil microbial function. We found that fungal communities were distinct across all sites, although fungal composition in the regenerating forest was more similar to the primary forest than either forest community was to the oil palm site. Ectomycorrhizal fungi, which are important associates of the dominant Dipterocarpaceae tree family in this region, were compositionally distinct across forests, but were nearly absent from oil palm soils. Extracellular enzyme assays indicated that the soil ecosystem in oil palm plantations experienced altered nutrient cycling dynamics, but there were few differences between regenerating and primary forest soils. Together, these results show that logging and the replacement of primary forest with oil palm plantations alter fungal community and function, although forests regenerating from logging had more similarities with primary forests in terms of fungal composition and nutrient cycling potential. Since oil palm agriculture is currently the mostly rapidly expanding equatorial crop and logging is pervasive across tropical ecosystems, these findings may have broad applicability.

“…The effects of former land uses, particularly agriculture, on ecosystems may be long-lived (Dupouey et al 2002;Thompson et al 2002;Uriarte et al 2004). However, variation in both agricultural practices and the ecological matrix make it difficult to draw generalizations about forest recovery processes although some general patterns are apparent (Guariguata and Ostertag 2001;Chazdon 2003).…”

Forest recovery in a tropical landscape: what is the relative importance of biophysical, socioeconomic, and landscape variables?

et al. 2009

Socioeconomic changes in many areas in the tropics have led to increasing urbanization, abandonment of agriculture, and forest re-growth. Although these patterns are well documented, few studies have examined the drivers leading to landscape-level forest recovery and the resulting spatial structure of secondary forests. Land cover transitions from agricultural lands to secondary forest in the island of Puerto Rico have been ongoing since the 1940s. This study is a glimpse into this landscape level trend from 1991 to 2000. First, we relied on Landsat images to characterize changes in the landscape structure for forest, urban, and agricultural land classes. We found that although forest cover has increased in this period, forest has become increasingly fragmented while the area of urban cover has spread faster and become more clustered. Second, we used logistic regression to assess the relationship between the transition to forest and 21 biophysical, socioeconomic, and landscape variables. We found that the percentage of forest cover within a 100 m radius of a point, distance to primary roads and nature reserves, slope, and aspect are the most important predictors of forest recovery. The resulting model predicts the spatial pattern of forest recovery with

“…Additionally, cultural and tillage practices before abandonment have marked consequences on overall vegetation development (Bonet 2004), and agricultural land use intensity and site history may have irreversible effects on subsequent biodiversity (Bossuyt et al 1999;Dupouey et al 2002). Successions may also differ due to varying climate conditions or diaspore supply in the initial stage (Schmidt 1981;1983;Peet 1992).…”

This paper compares vegetation composition, light availability, carbon and nutrient pools and Ellenberg indicator values among four old-field successional permanent plots that have received an initial treatment (ploughing, herbicide or sterilisation) prior to being left undisturbed in 1969, a second set of six plots received additional treatments (continued ploughing or mulching until 1982). On all plots species rich pioneer forests developed. Vegetation still varies among plots with different initial treatments: Sterilised plots can be distinguished from the others by dominance of Betula pendula, ploughed plots by Fraxinus excelsior, whereas herbicide-treated plots are intermediate with proportions of both species. By affecting light availability at the ground, tree species in turn influences ground vegetation and soil properties. Light availability turned out to be the dominant factor determining the composition of the vegetation in old-field succession.
