Abstract:Researchers concerned with sustainable management of forests in the tropics have argued that the road to improved stewardship of forest resources is the transfer of responsibility to the local communities
“…This forest tenure structure has led to and supports a robust system of community-conserved areas and sustainable management for timber production, although the extent of these activities varies considerably by region (Bray et al 2003;Martin et al 2011). Although it has slowed by 55 percent from the previous decade, the average rate of deforestation from 1990 to 2010 was approximately 0.39 percent annually (Food and Agriculture Organization 2015), with land use change broadly contributing an estimated 3.34 percent of the country's total greenhouse gas emissions (World Resources Institute 2016).…”

“…There are sixteen distinct indigenous groups in the state, which is one of the few in Mexico to legally recognize indigenous customary law and governance practices, and approximately 80 percent of the territory is held communally as legally recognized nucleos agrarios (Gonzalez Rıos 2011). Unlike Chiapas, the functionality of governance at the community level, as well as strong state-level umbrella organizations and NGOs, has led to robust systems of and experience with natural resource management and protection, including community forestry, cooperative coffee, and community protected areas (Bray et al 2003;Gonzalez Rıos 2011). (Bray 2012).…”

“…Approximately 60% of Mexico's forested area (including both temperate and tropical forests) is managed by local communities [11]. This depth of experience has made Mexico a leading example of community-based forest management [12]. Among Mexican wet tropical forests, those in the state of Quintana Roo in the Yucatan Peninsula stand out because of their great extent (4.4 Mha; [13,14]) and their high degree of conservation, which has been attributed to their three decades under community-based management [15][16][17].…”
Sustainable management of tropical forests is essential for conserving the ecosystem services they provide and protecting the livelihoods of the millions of people who depend on these forests. Community-based forest management in Quintana Roo, Mexico, has shown that conserving forests while generating economic benefits is achievable in the tropics. However, this management is carried out with technical gaps that jeopardize sustainable use of these resources. Crucial among these gaps is a lack of equations for precise calculations of logged timber volumes. Current equations employ a proportion of bark volume (PBV) of 0.14 for mahogany and a flat 0.10 for species with dense woods, despite their wide variation in bark thickness. Here, using Meyer's method, we calculated species-specific PBVs for the most commercially-important species in the Felipe Carrillo Puerto community-based logging operation. For most species, the new PBVs were smaller, indicating that wood volumes are currently underestimated. However, for two species, PBVs were higher. New values could influence the profits of the local enterprise and on the management of some of the most commercially-important species of Mexico's tropical forests through changes in the numbers of individuals felled.
“…Over the past few decades, the view that biodiversity rich areas partially or largely managed by local residents, sometimes referred to as community-conserved areas (CCAs), can be effective in saving species from extinction, has gained considerable ground [13,14]. Several ecological studies have been carried out in sacred forest patches.…”
The present study was carried out in four community based religious conserved forests areas i.e., Ansuiya Devi, Ulkagari, Maroor and Jameshwar in Garhwal Himalaya. The aim of the study was to access the ecological and diversity status. The selected sites have status either of reserve forest, communal forest/Van Panchyat or a combination of these apart from having several temples of religious significance. Study was conducted following the stratified random sampling technique by placing random quadrats of 10 m × 10 m size at forest floor. A total of 240 species of plants were recorded from the four study sites, which varied from 93 in Jameshwar to 119 in Ansuiya Devi. The density of these forests ranged from lowest of 782 trees/ha in Jameshwar to 1352 trees/ha in Maroor. The total basal cover (TBC) for trees showed a range of 31.67 m 2 /ha in Ulkagari to 84.34 m 2 /ha in Ansuiya Devi. Distribution pattern of whole herb and shrub layers were found contagious whereas only three tree species were found randomly distributed. Shannon diversity index (Hʹ) for tree species was recorded highest in Ansuiya Devi (2.93) whereas; lowest value (2.10) was recorded in Maroor. Species richness (Margalef index) for trees ranged from 3.29 to 4.35. The study is a pioneer in the aspect and can be helpful in making protocols and policy implications to protect these sites by involving local communities in biodiversity conservation outside the protected area network.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
