AbstractForest soil and litter is inhabited by a diverse community of animals, which directly and indirectly rely on dead organic matter as habitat and food resource. However, community composition may be driven by biotic or abiotic forces, and these vary with changes in habitat structure and resource supply associated with forest land use. To evaluate these changes, we compiled comprehensive data on the species composition of soil animal communities and environmental factors in forest types varying in land-use intensity in each of three regions in Germany, i.e., coniferous, young managed, old managed, and unmanaged beech forests. Coniferous forests featured high amounts of leaf litter and low microbial biomass concentrations contrasting in particular unmanaged beech forests. However, soil animal diversity and functional community composition differed little between forest types, indicating resilience against disturbance and forest land use. Structural equation modelling suggested that despite a significant influence of forest management on resource abundance and quality, the biomass of most soil fauna functional groups was not directly affected by forest management or resource abundance/quality, potentially because microorganisms hamper the propagation of nutrients to higher trophic levels. Instead, detritivore biomass depended heavily on soil pH. Macrofauna decomposers thrived at high pH, whereas mesofauna decomposers benefitted from low soil pH, but also from low biomass of macrofauna decomposers, potentially due to habitat modification by macrofauna decomposers. The strong influence of soil pH shows that decomposer communities are structured predominantly by regional abiotic factors exceeding the role of local biotic factors such as forest type.

The Future

The development of the forester's leadership role in forest land management is compared to rising profile of land between a sea or lake shoreline and a range of mountains, the progression is upward but the rate of climb changes. No plateau is identified. Reference is made to forestry leadership in several fields of forest land management; administration, land use, planning, research, forest management, recreational land use and fish and wildlife management. It is noted that forest land management includes activities for which foresters were not academically trained and reference is made to the fact that non-foresters, e.g. biologists and geographers are giving leadership in forest land management and thus providing beneficial competition and stimulation. The most important leadership role in the future may relate to regional planning. The forestry profession is cautioned not to abdicate this field to those in other disciplines.

In an earlier special issue of this journal, Marsh & Greer summarized forest land use in Sabah at that time and gave an introduction to the Danum Valley Conservation Area. Since that assessment, during the period 1990–2010, the forests of Sabah and particularly those of the ca 10 000 km 2 concession managed on behalf of the State by Yayasan Sabah (the Sabah Foundation) have been subject to continual, industrial harvesting, including the premature re-logging of extensive tracts of previously only once-logged forest and large-scale conversion of natural forests to agricultural plantations. Over the same period, however, significant areas of previously unprotected pristine forest have been formally gazetted as conservation areas, while much of the forest to the north, the south and the east of the Danum Valley Conservation Area (the Ulu Segama and Malua Forest Reserves) has been given added protection and new forest restoration initiatives have been launched. This paper analyses these forest-management and land-use changes in Sabah during the period 1990–2010, with a focus on the Yayasan Sabah Forest Management Area. Important new conservation and forest restoration and rehabilitation initiatives within its borders are given particular emphasis.

Special Region of Yogyakarta (DIY) experience the dynamics of changes in land use so that the decline in the forest area of the country. The government set the FMU Forest Management Unit as part of efforts to protect the forests remain sustainable so we need a study that could support optimal implementation of the Management Plan Forest Management Unit (FMU RP). One method to support the optimization is to do a land change prediction models. The purpose of this study include: (1) analyze the land use change from 1990 to 2013 period and (2) predicting the year 2023. Changes in land use land studied is 1990 and 2013, which would then be used as a base projection in 2013-2023. Methods to be used are: 1) Analysis of input output, 2) the integration of Markov chain Celullar automata (CA-MC) with logistic regression. The prediction model will use two scenarios, namely: 1) the existing condition of the existing and 2) the assumption of government intervention with the basic rules. The results showed in the period of 1990-2013 there is a change of land use is of 23%, or around 3,703 ha. From the results predicted changes in land use in 2023, with scenario 1 change-forest land dry land agriculture as an area of 1,337 ha and a change of scenario 2 of forest land area of 1264.36 ha.

Forested Landscapes

Canadians desire involvement in forest management at normative or early planning phases. One way of accomplishing this is through meaningful public involvement in land-use planning efforts. The Provinces of Ontario and Manitoba have, respectively, completed or are completing the development of land use plans for large areas of forested landscapes. Both governments identified public participation as being an integral part of these processes. This paper examines how well these processes promoted participation by the general public, the vast majority of which resides in urban areas located outside the respective planning regions. It is determined that in both cases this was poorly done. Reasons are given for why and how increased participation by the urban public should be pursued.

ABSTRACT Land-use and soil characteristics drive variation in soil community composition, but the influences of these factors on dispersal and community assembly at regional scale remain poorly characterized. Land-use remains a consistent driver of soil community composition even when exhibiting patchy spatial distribution at regional scale. In addition, disturbed and early successional soils often exhibit stochastic community assembly patterns. These observations suggest local community composition is influenced by dispersal and assembly from regional species pools. We examined bacterial community assembly within agricultural cropland, old-field, and forested sites across 10 landscapes in the region around Ithaca, New York (USA). We found that the Sloan neutral model explained assembly well at regional scale (R2 = 0.763), but that both soil pH and land-use imposed selection that shaped community composition. We show that homogeneous selection was a dominant assembly process with respect to both soil pH and land-use regime, but that these two factors interacted in their effects on bacterial community assembly. We conclude that bacterial community assembly at a regional scale is driven by dispersal from regional species pools and local selection on the basis of soil pH and other soil characteristics that vary with land-use.

Traditional Agroforestry

For centuries, many indigenous peoples across the archipelago have adopted customary agroforestry practices that are evidently sustainable. Forest Management Units (FMUs) or KPHs, intended to improve forest management at the ground level therefore, need to adopt policies that can align with, complement and strengthen existing local land-use systems. The purpose of this research is to gain an understanding on how KPH policies, those with direct implications on the ground, can be aligned with indigenous peoples' traditional agroforestry systems of Buru. We used a qualitative descriptive approach based on in-depth interviews with key informants and focus group discussions with indigenous groups of Buru.Results show that the indigenous peoples of Buru have and continue to follow a set of norms and rules in their forest land management practices: lands are utilized to plant various agricultural commodities that are combined with forest species which are left to grow naturally upon clearing land for agriculture or in establishing gardens. There are also norms and rules in establishing fields and gardens, starting from clearing of the land, to maintenance, to harvest. Every family in villages own fields and gardens, making them a vital part of community life. KPH policy of land use at the site level requires an understanding of how rules of resource use can be made compatible with and support community needs. In the operationalization of KPH, indigenous peoples’ rights to regulate the use of forest land, access to forest land use, and use of forest products need to be accommodated so that these communities continue to benefit from activities on their land.

Avian Assemblages

Habitat change following forest management may reduce biodiversity in boreal forests, as it has done globally in many forest types. Postharvest silviculture (PHS) is implemented to improve the yield of commercial tree species and has been applied to large areas of boreal forests. PHS may also influence animal communities and so we assessed songbird responses to these treatments in stands 20–52 years old in Ontario, Canada. We expected that several old-forest species would respond positively to PHS, that avian assemblages in treated forests would be distinct from those in untreated managed forests regardless of age, and that assemblages in our oldest treated stands would begin to converge with those of mature unmanaged forests. PHS stands had higher conifer density than naturally regenerating managed stands. The avian assemblage differed between treated and untreated stands at 20–30 years but not at 31–52 years. Convergence with old-forest assemblages was incomplete at 31–52 years after harvesting, although abundances of seven of 13 old-forest species did not differ from those in unmanaged forests. Of 10 old-forest species with competitive models, only Bay-breasted Warbler (Setophaga castanea (Wilson, 1810)) responded positively to PHS at the stand level, whereas two species responded positively at the landscape scale. Brown Creeper (Certhia americana Bonaparte, 1838), Boreal Chickadee (Poecile hudsonicus Forster, 1772), and Blackburnian Warbler (Setophaga fusca (Müller, 1776)) were absent from most managed stands and so require specific attention in planning for forest management, including retention of old-forest and delaying harvest of second-growth stands to ensure their occurrence and persistence.

The reserve “Stolby” is characteristic key plot of the mountain-taiga and subtaiga-forest steppe altitudinal belts in the East Sayan Mountains, where anthropogenic influence is the least pronounced. It was founded in 1925, in 15 km southward of Krasnoyarsk city, on north-west spurs of the Western Sayan Mountains which adjoin closely to right bank of the Yenisei River bordering upon the Middle Siberian Plateau. Reserve's physiography is characterized by low mountain and middle mountain erosion-accumulation relief with absolute heights of 200-800 m. Low mountain part (200-500 m) is composed of loose sedimentary rocks. In the middle mountain part of the reserve (500-800 m) there are outcrops of sienite rocks of various stages of destruction. Vegetation and soils of the reserve change in agreement with absolute heights and climate. In low mountains spread the subtaiga and forest-steppe leaved-light needle forests on mountain grey forest soils (8.1 % of reserve territory); the middle mountain part is occupied by the light needle and dark needle taiga forests on mountain podzol soils (91.9 % of the area). As the basement for vegetation map we took the map of forest environments of reserve by T. N. Butorina compiled according to materials of land forest management of 1977 year. As the result of forest management near 2000 biogeocoenoses were distinguished. The type of biogeocoenosis, according to V. N. Sukachev, is selected as mapping unit. Biogeocoenoses were united into 70 groups of forest types, representing 21 series of associations which are reflected in the map legend (Fig. 1). The main goal of map is to show the territorial distribution of groups and series of types of biogeocoenoses in the main structural units - altitudinal be't complexes (ВПК) which are equivalents of altitudinal vegetation belts. For designation of forest tree species various kinds of hatches were used. Formations of Siberian pine, larch, pine, fir, spruce, birch and aspen forests are shown on the map. Within the ВПК arabic numerals show the groups of types of biogeocoenoses (forest types), united into series according to similarity of dominants in ground layer. The mountain-taiga ВПК includes the following series and groups of types of biogeocoenoses: dwarf-shrub-moss (1-4); sedge-moss (5-9); bilberry-low herb-moss (10-14); tall herb-sedge (15-19); tall herb-wood sour-moss (20-26); tall herb-small reed (27-32). The subtaiga-forest steppe ВГ1К embraces: shrub steppificated (33-34); shrub-forb steppificated (35-38): sedge- bilberry (39-40); sedge-forb (41-43); bracken (44); small reed-forb (45); bilberrv-forb- sedge (46, 47); forb-tall herb (48-51); tall herb (52-55); wet tall herb-small reed (56-59); fern-tall herb (60). Intrazonal phytocoenoses: brook tall herb (61-63); brook shrub (64-68); lichen-moss (69); cowberry (70). In 1999-2000 on the base of topographic map in a scale 1 : 25 000, map of forest environments, transformed by us into vegetation map of the reserve, M. J . Erunova and I. S. Scerbinina worked out an electronic variant. For this project the instrumental facilities of GIS, GeoDraw and GeoGraph (CGI IG RAS, Moscow) and programs of Geophyt were used.
