“…Hohnwald et al [ 35 ] reported that I. edulis was a ‘high’ producer of woody and leafy biomass, a frequently occurring tree in Capoeira, a nitrogen fixing legume and palatable to cattle. Hohnwald [ 20 ] reported that I. edulis had ‘bad performance’ on a scale of palatability and biomass, which suggested it had poor forage quality and was given an ‘intermediate’ value for mortality. However, the same study reported that I. edulis suffered from the overgrown grass sward during the establishment phase, but when established it was robust.…”

“…Some tree forages have also shown potential to reduce ruminant methane emissions [ 17 , 18 ]. There are tree species native to the Amazon that are palatable to cattle and show potential for domestication in silvopastoral systems [ 19 , 20 ]. In the Bragantina region of Northern Brazil, Hohnwald et al [ 21 ] demonstrated that the integration of woody species had the potential to enhance forage production, ecological stability and sustainability when compared to grass monocultures.…”

Assessing the palatability of forage from locally adapted trees could improve the sustainability of livestock production systems. However, grasses continue to dominate livestock feed across the Amazon. We established a silvopastoral cattle farming system in Peru, comparing three different forage tree species with grass monocultures using a randomised block design. Trees were arranged in alleys of 0.5 × 7.5 m, planted alongside grass, and were directly browsed by cattle. Browse removal was estimated by three methods: destructive sampling, canopy measurements and leaf counts. We found that all three tree species were palatable to cattle. Plots containing trees and grass produced more available forage (mean > 2.2 Mg ha−1) for cattle than the grass monocultures (mean = 1.5 Mg ha−1). Destructive sampling below 1.6 m demonstrated that cattle consumed 99% of the available Erythrina berteroana forage, 75% of the available Inga edulis forage and 80% of the available Leucaena leucocephala forage in 8 days. This research demonstrates methodologies to estimate the intake of locally adapted browse species by cattle and highlights the potential benefits of silvopastoral systems in the Amazon. Planting trees could also benefit animal health and provide ecosystem services such as soil regeneration, enhanced nutrient cycling and carbon capture.

“…Cratylia argentea (Cratylia) is a leguminous shrub species, native to the South American Savanna [1], but also observed in the Amazon and Caatinga biomes [2]. Some important characteristics of this leguminous shrub are its ability to thrive in acidic soils characterized by high aluminum saturation and low fertility [3], as well as its great palatability for ruminants [4]. Cratylia stands out as a forage source with great potential for tropical areas with extended dry seasons [5].…”

Cratylia argentea is a leguminous shrub that has the potential for use as livestock feed in tropical areas. However, time-consuming and labor-intensive methods of chemical analysis limit the understanding of its nutritive value. Near-infrared spectroscopy (NIRS) is a low-cost technology widely used in forage crops to expedite chemical composition assessment. The objective of this study was to develop prediction models to assess the crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), and dry matter (DM) of Cratylia based on NIRS and partial least squares analysis. A total of 155 samples were harvested at different maturity levels and used for model development, of which 107 were used for calibration and 48 for external validation. The cross-validation presented a root mean square error of prediction of 0.77, 2.56, 3.43, and 0.42; a ratio of performance to deviation of 4.8, 4.0, 3.8, and 3.4; and an R2 of 0.92, 0.92, 0.87, and 0.84 for CP, NDF, ADF, and DM, respectively. Based on the obtained results, we concluded that NIRS accurately predicted the chemical parameters of Cratylia. Therefore, NIRS can serve as a useful tool for livestock producers and researchers to estimate Cratylia’s nutritive value.

“…Intact Umbrisols and Histosols under natural or near-natural forest cover are particularly vulnerable to land degradation and should be protected. Therefore, it is important to find silvicultural alternatives that consider tree protection and sustainable management, for instance, by the integration of secondary vegetation [55,56] or the use of silvo-pastoral systems [57].…”

Abstract:The Andes of northern Peru are still widely covered with forests, but increasingly suffer from habitat fragmentation. Subsequent soil degradation often leads to the abandonment of overused forests and pastures. Ecological knowledge on the restoration potential, e.g., on dependencies of soil conditions and altitude, is scarce. Therefore, we compared soil and vegetation patterns along nine transects within the upper Pomacochas Basin, which is an important biodiversity corridor along the Andes, between remaining forests, succession sites and pastures. Anthropogenic successional and disturbance levels, geological substrate, and altitude have the most important ecological impacts on vegetation and tree species composition. Species responded to sandstone versus calcareous substrates, but also to depths of the organic soil layer, and light conditions. The absence of organic layers under pastures contrasted with the accumulation of thick organic layers under forest cover. Vegetation composition at succession sites revealed certain starting points (herbal stage, bush stage, or secondary forest) for restoration that will determine the length of regeneration paths. Pre-forest patches of Alchornea sp. and Parathesis sp. may act as habitat stepping stones for expeditiously restoring biocorridors for wildlife. The key findings can contribute to the sustainable use and conservation of biodiversity in a fragile ecoregion.
