Estimating Energy Concentrations in Wooded Pastures of NW Spain Using Empirical Models That Relate Observed Metabolizable Energy to Measured Nutritional Attributes

Wooded pastures serve as a traditional source of forage in Europe, where forest grazing is valued as an efficient tool for maintaining the diversity of semi-natural habitats. In a forest grazing setting with diverse diet composition, assessing the energy content of animal diets can be a difficult task because of its dependency on digestibility measures. In the present study, prediction equations of metabolizable energy (ME) were obtained performing stepwise regression with data (n = 297; 44 plant species) on nutritional attributes (Acid Detergent Fiber, lignin, silica, dry matter, crude protein, in vitro organic matter digestibility) from 20 representative stands of Atlantic dry heathlands and pedunculate oak woodlands. The results showed that the prediction accuracy of ME is reduced when the general model (R2 = 0.64) is applied, as opposed to the use of the specific prediction equations for each vegetation type (R2 = 0.61, 0.66, 0.71 for oak woodlands; R2 = 0.70 heather-gorse dominated heathlands, R2 = 0.41 continental heathlands). The general model tends to overestimate the ME concentrations in heaths with respect to the observed ME values obtained from IVOMD as a sole predictor, and this divergence could be corrected by applying the specific prediction equations obtained for each vegetation type. Although the use of prediction equations by season would improve accuracy in the case of a Winter scenario, using the general model as opposed to the prediction equations for Spring, Summer or Fall would represent a much smaller loss of accuracy.

Impact of the Disturbances for Forest Grazing on Flora Composition in a Natural Forest

Daegwallyeong is a mountain pass at an altitude of 832 m, which has been designated a conservation area because of its essential role in Korea’s forest ecosystem. Simultaneously, this area is considered a suitable place for forest grazing due to the cool temperature during the summer. Some areas have been converted to grassland for livestock feeding, and the scale has continued increasing. Although livestock in a forest area is more ecofriendly than industrialized facilities, it could impact the native ecosystem, especially in terms of the flora and vegetation. We investigated the changes in flora and vegetation of Daegwallyeong before and after the grassland formation. The total number of vascular plant species changed throughout the survey period. It was decreased by thinning and forest floor removal in 2015. However, it bounced back to the original number in 2016, even after grazing. However, there was a dramatic decrease after the second forest floor removal and 3 months of grazing in 2017. The number of flora slightly increased after the fallow of grazing in 2019, but it did not fully recover. Although the number of flora seemed back to normal, the composition of the flora in 2019 was significantly changed from the forest without disturbance in 2014. First, there was the invasion of naturalized plants such as Taraxacum officinale and Barbarea vularis, as well as ecosystem-disturbing flora such as Carex callitrichos var. nana and Rumex acetosa. Second, the coverage of those species expanded after thinning and grazing. Most importantly, we lost five valuable rare species, Anemone koraiensis, Viola diamantiaca, Chionanthus retusus, Scopolia japonica, and Streptopus ovalis, from the area. Additionally, the ground condition of the area was severely damaged, and plants no longer grow in some areas. The survey and analysis of plants in this study showed the adverse effects of forest grazing practices on rare plants in Daegwallyeong. Forest grazing practices should be carefully conducted to preserve vulnerable plant species and a healthy ecosystem.

Capitalism in Central Norrland, Sweden, during the Iron Age

The authors challenge the opinion that a traditional hunter-gatherer culture existed during the Iron Age in the forested interior of central Norrland (En. Northern Sweden). Two new and several earlier pollen analyses together with osteological finds from domestic animals confirm that extensive forest grazing was widespread throughout the interior. The distribution of iron slag deposits suggests that iron production is a key factor to understanding the society in the area. The modes of subsistence, the low-technology ironwork, and a common conceptual world as reflected in the graves on the coast and in the interior can be viewed as elements of an early capitalistic system.

The importance of livestock grazing at woodland-grassland interface in the conservation of rich oakwood plant communities in temperate Europe

Traditional husbandry fostered rich semi-open oakwood communities composed of forest and non-forest species. In the eastern Carpathian region, silvo-pastoralism was commonplace by the mid-1900s. This study aimed to determine the state of the preservation of the ecotonal character of grassland-woodland interfaces in formerly pastured cultural landscapes of SE-Polish Carpathian foothills and W-Ukrainian Ciscarpathia in the context of land-use change. In the first region, despite the long-lasting history of forest grazing amongst mainly arable land, the post-WWII collapse of husbandry and the imposed ban on forest grazing, has led to swift development of dense undergrowth and establishment of impermeable ecological woodland-open habitat barrier. As a result, former silvo-pastoral oakwoods developed the features of the Tilio-Carpinentum forest community although some forest species have not yet moved in due to their poor dispersibility. The much younger oakwoods in the Ukrainian study region are remnants of the sparsely treed grasslands, some of which had been ploughed in the mid 20th century. Their semi-open canopy structure, maintained through repetitive grass burning, contributes to the communities ecotonal character, but without regular livestock-led plant “spill-over” from the grassland, the oakwoods remain species-poor. The restoration of species-rich semi-open oak woods requires “unsealing” the forest-grassland interface, reducing the degree of canopy closure, and opening that zone up to extensive grazing—an important seed dispersal vector.

Prohibited, but still present: local and traditional knowledge about the practice and impact of forest grazing by domestic livestock in Hungary

Background Forests have been grazed for millennia. Around the world, forest grazing by livestock became a controversial management practice, gradually restricted in many countries over the past 250 years. This was also the case in most Central and Eastern European countries, including Hungary, where forest grazing was a legally prohibited activity between 1961 and 2017. Until the 2010s, ecologists and nature conservationists considered it merely as a historical form of forest use. As a result, there is little contemporary scientific information available about the impact of forest grazing on vegetation and the traditional ecological knowledge associated with it. Our aim was to explore and summarize this type of knowledge held by herders in Hungary. Methods We interviewed 58 knowledgeable herders and participated in forest grazing activities in 43 study locations across the country. The results were analysed qualitatively. Results We revealed a living ecological knowledge tradition and practice of forest grazing in native and non-native forest stands. The impact of livestock grazing on native and non-native forests is not considerably different, in the view of the herders. For both forest types, the greatest impact of grazing was the suppression of the shrub layer, while grazing also increased the dominance and palatability (“tameness”) of the grasses. Livestock could cause significant damage to seedlings during forest grazing, but if done with care, grazing could also be an integral part of forestry management. Conclusions Sustainability of current forest grazing practices depends on the depth of local and traditional knowledge applied and herders’ stewardship. We stress the importance of collaborating with holders of local and traditional knowledge in order to gain a better understanding of the effects of livestock grazing on vegetation in temperate forests.

Model Pengelolaan Ternak di Sekitar Hutan Gunung Mutis dan Dampaknya terhadap Kelestarian Hutan

Penelitian ini mengkaji kelayakan finansial dan dampak dari model pengelolaan ternak yang ditemukan di sekitar hutan Gunung Mutis di Pulau Timor. Data dikumpulkan melalui wawancara terhadap 40 masyarakat sekitar hutan. Terdapat dua model pengelolaan ternak yang ditemukan di sekitar hutan. Model pertama adalah model pemeliharaan ternak di dalam kandang dan model kedua adalah model penggembalaan ternak di hutan. Hasil penelitian menunjukkan bahwa kedua model layak secara finansial. Namun demikian, jika menggunakan biaya tenaga kerja komersial, model pemeliharaan ternak di dalam kandang secara finansial tidak layak untuk dilakukan, sedangkan model penggembalaan di hutan layak secara finansial. Model pengelolaan ternak di dalam hutan berdampak negatif terhadap regenerasi pohon sedangkan model pemeliharaan ternak di dalam kandang tidak berdampak negatif terhadap kelestarian hutan. Dari hasil penelitian disarankan agar pemerintah membatasi areal untuk penggembalaan ternak di hutan.Kata kunci: kelayakan finansial; model silvopasture; Mutis; penggembalaan ternak hutan; Timor Livestock Management Models Around Mt. Mutis Forest and Its Impact on Forest SustainabilityAbstractThe study examined the financial feasibility and impacts of livestock management models found around Mt. Mutis forest in Timor Island of Indonesia. Data was collected through interviewing 40 communities around the forest. There were two livestock management models around the forest, the first model was livestock management which raise livestock in the cattle pen, and the second model was livestock management which graze livestock in the forest. This study found that both livestock management models were financially feasible. However, if commercial cost of workers was counted, the livestock management model which raise livestock in the cattle pen was financially not feasible while livestock management model which graze livestock in the forest was financially feasible. Livestock management model which graze livestock in the forest however had negative impacts on the regeneration of trees. On the basis of this study, it is suggested that the government should limit the forest area that could be used for forest grazing.
