The Government of the Islamic Republic of Afghanistan (GIRoA), in power during 2002–2021, initiated the process of instituting community-based forest governance and building local capacity for natural resource management. These efforts coincided with the presence of international security forces and the mobilization of civil society organizations, and they were in response to community aspirations to protect and restore often degraded local forests. Legislation was passed to enable forest protection and management, including a provision to encourage participatory management by local community user groups organized as Forest Management Associations (FMAs). By the end of the GIRoA era, c. 20 registered FMAs were operating with c. 400 others in various stages of development across Afghanistan. Our analysis of relevant policy documents revealed that the policy framework developed during the GIRoA era scores favourably on the ideal criteria for community-based resource management. Despite the change in political administration with the inception of the current Islamic Emirate of Afghanistan regime, the influence of the GIRoA era serves as a starting point and may have enduring influences on rural communities in Afghanistan and the natural resources that support them. Anecdotal evidence suggests that community-based forest management may persist under the current national leadership despite international isolation and funding constraints. The model developed in Afghanistan may be relevant to other fragile states, especially in contexts where rural forest-dependent communities have strong local institutions, such as shuras, and where forests are not prone to heavy extraction pressure.

Approximately 80% of neotropical forests are subject to unsustainable economic practices, such as logging. Spiders are a megadiverse taxonomic group with a particularly great diversity in forest ecosystems and could help indicate the sustainability of logging operations. At six sites at 400–700 m altitude in the piedmont forest of north-western Argentina, spiders collected using pitfall traps and forest structure and spider assemblage structure variables were quantified in order to examine the association between them and to identify indicator spider families. Logging changes forest structure and seems to generate an unsuitable habitat for spiders associated with mature forests. The family taxonomic level is a good surrogate for spider morphospecies. The Mysmenidae, Nemesiidae, Theridiidae, Pholcidae, Hahniidae and Tetragnathidae families were associated with upper canopy cover of 20% or more and with more than two dead fallen trees per 0.1 ha and >15 live trees per 0.1 ha, found in unlogged forests. Bearing in mind that the piedmont forest of north-western Argentina is being logged in the absence of sustainability criteria, we suggest including spiders in monitoring schemes to complement the information obtained from more readily used groups, such as charismatic vertebrates.

To conserve biodiversity on forest landscapes, it is necessary to understand how incentives in an offset market affect the dynamics of habitat loss and restoration. In this study, a model of firm behaviour in a temporary biodiversity offset market is developed to understand the impact of offset rules on the dynamics of land use and offset policy costs and benefits for Alberta's boreal forest. Policy treatments include eligibility rules for restoration versus avoided loss; time lags for crediting restoration benefits; and geographic trading restrictions. The analysis highlights the assumptions and trade-offs embedded in offset principles such as additionality. Restoration-based policies, which require biodiversity benefits to be established prior to development, are over 200 times more costly than policies that include avoided loss. Geographic trading restrictions result in a significant redistribution of policy costs and ecological risks between regions, with little impact on aggregate policy costs and benefits. Including avoided loss results in a decline in biodiversity intactness by 2% to 2.2% compared to a decline of 3.6% under a no-offset policy. Increasing time lags for crediting restoration to match ecological recovery trajectories reduces restoration effort when policies include both restoration and avoided loss.

There is a huge annual trade in Himalayan medicinal plants but only limited information on their sustainable use and conservation. The aim of this paper is to investigate if sustainable commercial medicinal plant management is promoted by forest policy formation and implementation in Nepal. Data was obtained through 175 semi-structured interviews with persons from five stakeholder groups involved in commercial alpine medicinal plant exploitation and conservation in Nepal: harvesters, traders, District Forest Office staff, staff at departments and ministerial level of the Ministry of Forests and Soil Conservation, and international and local NGOs and donors. The emphasis was on recording respondents' views on the official mechanisms regulating harvest of alpine commercial medicinal plants. It was found that current approaches to non-timber forest policy formation and implementation need to be revised if objectives of conservation and sustainable management are to be achieved. Identified problems include exclusion of harvesters from the policy formation process and widespread agreement among respondents that current collection permits and bans do not strongly affect resource utilization.
