“…The strategic placement of these plantations in watersheds and erosion-prone areas means that per unit forest area, the watershed and soil services they provide are also greater (Izquierdo and Clark 2012). Plantations have much lower biodiversity than native forests but they do provide habitat for some species, especially in association with the corridors, and they frequently act as buffers of native forests, which limits access and expands the habitat for jaguars, peccaries, and other large vertebrates (Di Bittetti et al 2006, Paviolo et al 2008, Zurita et al 2006. The economy of the province is dependent on forests for both industrial forest products and tourism (Izquierdo et al 2008).…”

ABSTRACT. New forests are expanding around the world. In many regions, regrowth rates are surpassing deforestation rates, resulting in "forest transitions," or net gains in forest cover. Typically measured only in terms of aggregate"'forest cover" change, these new forests are ecologically distinct from each other and from those originally cleared. We ask, what are the ecological attributes, goods, and services we might expect from different pathways of forest recovery? To address this question, we proposed a typology of forest transitions that reflects both their social drivers and ecological outcomes: tree plantation, spontaneous regeneration, and agroforestry transitions. Using case studies, we illustrate how the ecological outcomes of each transition type differ and change over time. We mapped the global distribution of forest-transition types to identify global epicenters of each, and found that spontaneous transitions are most common globally, especially in Latin America; agroforestry transitions predominate in Europe and Central America; and plantation transitions occur in parts of Europe and Asia. We proposed a conceptual framework to understand and compare the ecological services arising from different types of forest transitions over time: forest ecosystem-service transition curves. This framework illustrates that carbon sequestration tends to be comparatively lower in agroforestry transitions, and biodiversity recovery is lower in industrial plantations. Spontaneously regenerating forests tend to have relatively high biodiversity and biomass but provide fewer provisioning and economically valuable services. This framework captures the dynamism that we observe in forest transitions, thus illustrating that different social drivers produce different types of ecosystem-service transitions, and that as secondary forests grow, these services will change over time at rates that differ among transition types. Ultimately, this framework can guide future research, describe actual and potential changes in ecosystem services associated with different types of transitions, and promote management plans that incorporate forest cover changes with the services and benefits they provide.

“…This result emphasizes the importance of using native plant species in silviculture systems, which reduces the negative impact on the local fauna. Studies of bird assemblages confirm this statement (zurita et al, 2006;volPato et al, 2010). The presence of the understory in exotic plantations allowed Mottle-cheeked Tyrannulet to use the different foraging substrates, showing differences in the height, angle and frequency of utilization of attack maneuvers between the Pinus plantations.…”

ABSTRACT. Few studies have related the effects of silviculture practices to the behavior of bird species in the Neotropics. The present study examined the foraging behavior of Phylloscartes ventralis (Temminck, 1824) in a native forest and in silviculture areas of Pinus elliotti and Araucaria angustifolia with different structures and ages. We tested two general hypotheses: (1) areas of commercial forest plantation change the foraging behavior of P. ventralis in relation to native forest, and (2) the foraging behavior of P. ventralis in silviculture areas with understories (complex structures) is different from its behavior in areas without understory. The results showed that P. ventralis changed its foraging behavior depending on the type of forest, and on the presence of an understory in silviculture areas. Main changes involved the height and angle of substrate where the prey was captured. Phylloscartes ventralis showed the same set of attack maneuvers, with more maneuvers type in young Pinus planted without understory. The frequency of use of attack maneuvers was more similar in areas of silviculture with understory and in the native forest. The results highlight the importance of an understory structure and the utilization of native plant species in silviculture practices, to the foraging behavior of native bird species.

Comportamento de forrageio dePhylloscartes ventralis (Aves, Tyrannidae) em florestas nativas e plantadas no sul do Brasil. Poucos estudos têm relacionado os efeitos que práticas silviculturais exercem sobre o comportamento de aves neotropicais. O presente estudo analisou o comportamento de forrageio de Phylloscartes ventralis (Temminck, 1824) em uma floresta nativa e em áreas de silvicultura de Pinus elliottii e Araucaria angustifolia com diferentes estruturas e idades. Foram testadas duas hipóteses gerais: (1) áreas de plantio comercial alteram o comportamento e forrageio de P. ventralis em relação à mata nativa e (2) o comportamento de forrageio de P. ventralis em áreas de silvicultura com sub-bosque (estruturalmente mais complexas) é diferente do registrado em áreas sem sub-bosque. Os resultados demonstram que P. ventralis alterou seu comportamento de forrageio dependendo do tipo de floresta e da presença de sub-bosque em áreas de silvicultura. As principais mudanças envolvem a altura e o ângulo de substrato onde a presa foi capturada. Phylloscartes ventralis exibiu o mesmo grupo de manobras de ataque a presas, com um maior número de tipos de manobras em plantações jovens de Pinus sem sub-bosque. A frequência de uso de manobras de ataque a presas foi mais similar em áreas de silvicultura com sub-bosque e na floresta nativa. Os resultados destacam a importância do sub-bosque e da utilização de espécies nativas em práticas silviculturais para a manutenção do comportamento de forrageio de uma espécie de ave nativa.

“…Crop and forestry production are major drivers of deforestation and ecological degradation, both generally (Geist and Lambin 2002, Green et al 2005, Phalan et al 2011) and in the study system (Goerck 1997, Chiarello 1999, Rômulo et al 2003, Naidoo and Adamowicz 2006, Zurita et al 2006, Uezu et al 2008. The documentation of this relationship provides evidence of the mechanism linking agricultural/silvicultural income and supporting service decline.…”

Ecosystem service trade-offs and land use among smallholder farmers in eastern Paraguay

ABSTRACT. The trade-off between economically critical provisioning services and environmentally sustaining supporting services often seems absolute. Yet, when land use is inefficient, managers may be able to increase provision of both economically and ecologically sustaining services. To explore such sustainable "win-win" outcomes, I present a model of predicted trade-offs of provisioning and supporting services on smallholder farms in eastern Paraguay. The spatially implicit model simulates smallholder parcels as mosaics of subsistence agriculture, cattle pasture, eucalyptus plantations, and/or natural forest cover, and predicts provisioning and supporting service supply depending on the relative abundance of each land-use type per parcel. I represent provisioning services as the annual, per-ha proportion of a smallholder family's subsistence needs met by agriculture and forestry. I represent multidimensional supporting services as a composite index of forest bird biodiversity, soil organic carbon content, and aboveground annual net primary productivity (NPP) relative to what would be expected in a stand of high-quality Atlantic Forest. I use this model first to predict ecosystem-service supply for 38 actual smallholder parcels in rural eastern Paraguay, and then to generate an efficiency frontier that illustrates the optimal trade-offs between provisioning and supporting services that are biophysically possible for the system. Comparison of the empirical findings and the efficiency frontier indicates that current land use is inefficient relative to the biophysical optimum. All smallholder parcels included in the study but one lie far from the modeled efficiency frontier, indicating that for a given level of agricultural and forestry production, supporting services are not optimally conserved. If parcel owners were able to overcome constraints to sustainability by, for example, transitioning from cattle ranching to agroforestry production, they could protect high levels (often upward of 90%) of the supporting ecosystem services provided by natural forest without sacrificing economically valuable provisioning services. Pathways to such sustainable outcomes are discussed.
