Despite being one of the most heterogeneous Brazilian biomes, regardless of being the least known, the Caatinga is under strong anthropism. In this way the forest management offers techniques that, when used, guarantees the maintenance of the sustainability of the productive system, sustainability that is guaranteed through the resilience of the regenerative stratum. Thus the objective of this work was to evaluate the effect of forest management on natural regeneration in a caatinga area, under different cutting ages. The study was developed in the settlement of the agrarian reform, Brandão III, located in the city of Cuité-PB. To evaluate the natural regeneration, 40 plots measuring 5 × 5 m (25 m2) were randomly allocated within the plots exploited and in the Legal Reserve. All individuals with Circumference at baseline (CNB) ≤ 6 cm and with a minimum height of 0.5m were measured, and distributed in three height classes. A C1: 0.5 m < H < 0.99 m; C2: 1.0 m ≤ H < 1.99 m and C3: H > 2.0 m. The data of density, richness and number of individuals by type of regeneration origin were compared by the Tukey test at 5% significance. We sampled 2021 individuals, represented by 32 species, 27 genera distributed in 16 families. The exploration did not cause significant changes to the floristic composition nor to the richness of the species. The exploration and the time elapsed between the cut and the measurement influenced the increase of the density.

Local extinction of native Atlantic Forest flora species occurs mainly due to habitat fragmentation. Reforestation and natural regeneration can mitigate these factors. The present study attempts to understand whether floristic composition and dispersal processes are being reestablished in an area of lowland Atlantic Forest, eight years after its reforestation. The study area was an old pasture set between two urban fragments in the city of Recife that was reforested in 2011. Melastomataceae species were collected in this area and the morphology of their fruits was compared with the species of the family recorded in the adjacent fragments. Miconia prasina, M. albicans, M. affinis, Clidemia hirta, and C. capitellata have been found in the reforested area. Although there are species with larger fruits in the adjacent fragments, there was no statistically significant difference between the means of the two areas. The fruit morphology indicates that the species found in the area are dispersed by birds and small mammals. It is possible to conclude that the reforested area already presents the expected ecological processes for a corridor between two fragments. Thus, the two adjacent areas serve as vectors for the colonization of native Atlantic Forest species in the reforested area.

Aims: To evaluate the shrub-tree species of natural regeneration in a remnant of Tropical Rain Forest, located in the northeastern region of Brazil. Study Design:  Systematic sampling. Place and Duration of Study: The study was carried out in a remnant of Tropical Rainforest, categorized as a Forest of Miritiba Wildlife Refuge, located in the municipality of Abreu and Lima, distant approximately 42 km from the city of Recife, state of Pernambuco, Brazil. The area has approximately 273.40 ha. The data were collected in November 2016. Methodology: The data were collected in 12 plots (25 m² each) allocated in 3 transects of 100 m in length, equidistant 50 m from each other, perpendicular to the edge of the weir located inside the fragment. The inclusion level established was a minimum height of 1.0 m and a base circumference at 30.0 cm from the ground (CAB 0.30 m) ≤ 15.0 cm. Three height classes (H) were considered, where Class I included individuals with 1.0 ≤ H ≤ 2.0 m; Class II with 2.0 <H <3.0 m and Class III with H> 3.0 m and CAP <15.0 cm. Results: A total of 41 species belonging to 24 botanical families and 31 genus were recorded, representing a density of 8,867 ind.ha-1. The five richest families were Fabaceae, Myrtaceae, Melastomataceae Anacardiaceae and Sapindaceae. The species with the highest estimated densities were Protium heptaphyllum, Erythroxylum mucronatum and Hirtella racemosa. Conclusion: Among the species sampled in the regenerating component, which presented higher density and can be used for enrichment of areas in recovery process are Protium heptaphyllum, Erythroxylum mucronatum, Hirtella racemosa, Myrcia tomentosa and Eschweilera ovata.

Forest Management Plan

Abstract A forest management plan based on ecological principles and forest management sustainability was elaborated for the Domogt Sharyn Gol Company, Mongolia. We presented possibility of use of principles and methods traditionally utilized in forest management planning in the Czech Republic. A used methodology was adjusted for the forestry legislature in Mongolia. A stratification of site characteristics and the forest development type concept was used as a framework for assessment of a forest property state via an operational forest inventory. A randomly generalized network of 354 inventory plots on the total area of 3 194 ha with spacing of 300 × 300 m was established for measurements of tree species, natural regeneration and a volume of lying deadwood. We produced a text, table, graph, figure and map material consisted of areal, tree species and wood volume structuring including calculation of decenal logging, thinning treatments, plantation activities and natural regeneration support. This forest management plan provides a feasible perspective not only towards immediate commercial benefits but also towards sustainability of forest yield and other ecological forest functions. This way of management planning is also a save way towards mitigation of current environmental issues in a Mongolian forest landscape.

The establishment and interpretation of diameter and height structures are essential for forest management decisions. This study aims to describe the diameter structure and spatial distribution of Pinus halpensis populations in the Chettaba state forest (Constantine, Algeria). The knowledge of these parameters is an essential step for their sustainable management. The diameter at 1.30 m from the ground and the total height of P. halpensis individuals were measured on 6 plots along an altitudinal gradient. The height structure shows that trees in the height classes between 5 and 10m have a very high density, indicating low natural regeneration. The total structure indicates that smaller trees are more abundant than larger trees (17.5<d≤27.5cm). These results contribute to the improvement of knowledge on current condition indicators of natural Pinus halpensis stands that can be used as a basis in the management of Chettaba forest

The aim of the work is to show how, thanks to the GIS software, it is possible to increase the size of natural renovated surfaces. By concentrating a large amount of data and applying appropriate criteria, you can plan your business operations in a more accurate way. Along with the planned harvesting activities that are closely related to breeding work, for example, optimization of the export route network can be planned. The ESRI software that has been used in this work allows for and can facilitate planning in the long term of the forest management plan. The paper presents results of the analysis of habitats and pine stands suitable for natural regeneration, which in theory should give breeding success.

The relevance of the sustainable management of public green spaces (PGSs) has increased as a result of the global trend of urban growth, especially in arid and semi-arid cities where planners are faced with the challenge of maintaining or increasing plant cover (PC) without increasing water consumption. This study analyzed legal and administrative documents concerning the regulatory framework for PGS in the city of Hermosillo. In addition, the floristic composition and PC of a sample of PGSs (n = 112) was estimated and the impact of this framework was determined using a case study. Our results indicate that the afforestation pattern derived from the current regulatory framework is unsustainable, and it results in insufficient PC in green spaces. On average, exotic species accounted for 62% of the afforestation pattern and PC averaged 27%.

This paper highlights the lessons of using adaptive learning in community forestry that effectively help to resolve forest based conflicts in Terai region of Nepal. The paper is based on a three-year action research carried out in Terai. Qualitative methods including participatory rural appraisal tools and documentation of engaged action and reflections were used. Methods and tools that largely fall under adaptive learning were deployed. The field data was complemented by review of secondary data and literature on environmental history of Terai. We found that policies on land and forest in Terai for the last fifty years have induced and aggravated conflicts over access and control between state and communities and also within diverse groups of local communities. These conflicts have had serious negative impacts on sustainable management of forests and on local people’s livelihoods, particularly resource poor and landless people. Centralised and bureaucratic approaches to control forest and encroachment have largely failed. Despite investing millions of Rupees in maintaining law and order in forestlands, the problem continues to worsen often at the cost of forests and local communities. We found that transferring management rights to local communities like landless and land poor in the form of community forestry (CF) has induced strong local level collective action in forest management and supported local livelihoods. Moreover, adding adaptive learning, as a methodological tool to improve governance and enhance local level collective action significantly improves the benefit of CF. It implies that a major rethinking is needed in the current policies that have often led to hostile relationships with the local inhabitants- particularly the illegal settlers. Instead, transferring forest rights to local communities and supporting them through technical aspects of forest management will strengthen local initiatives towards sustainable management of forests.

Structured Questionnaire

The current study examines the importance of planning and management documents (notably the forest management plan and the regional forest plan) for public relations purposes. 17 people (15 forest engineers and 2 forest guards) were interviewed using a semi-structured questionnaire. The results of our survey show that some of the information used for public relations is taken from the planning documents. The forest management plan is primarily considered to be an internal document, but it also provides information on the objectives of forest enterprises, justifications of the planned measures, numbers and maps. The regional forest plan contributes to the public relations in three ways: its content provides information about objectives, description of forest functions, projects and measures. In addition, the participation of the public in the process of elaborating this plan is an ideal opportunity to heighten awareness in society and further public understanding of the forest and forestry services. Finally, as the regional forest management plan is in the public domain, it functions as a type of «show case» of the forest service.

Forest Management Plan

The silvicultural principles of a forest management plan for Canton Neuchâtel reveals itself as steeped in a systemic approach that allows us to consider the forest as a truly living system. In this context, it seems judicious to the author to conceive of the body forest personnel as a group of responsible people who share certain common ethics and who, in their work, promote the emergence of collective services recognised as beneficial to the state and which would be supported by public funding for the good of the entire community.

The City

The City and County of San Francisco (“City”) embarked upon a 30-year master planning process in part prompted by public concerns related to the neighbourhood impacts of the Southeast Water Pollution Control Plant (SEP). The Sewer System Master Plan, as it is called, developed a long term Integrated Urban Watershed Management Plan for the City's treatment plants and collection system. This paper focuses on the planning framework and public input to the process, particularly as it relates to proposed changes to the SEP. The resulting improvements address issues of replacing aging infrastructure, eliminating odor emissions, and visually screening the treatment plants that are situated within an urban setting. The recommended project addresses the needed repair of the existing infrastructure; and proposes that the City move towards an integrated urban watershed approach, initially through localized rainwater harvesting and opportunistic water reclamation.
