Silvicultural Practices in the Management of Diospyros melanoxylon (Tendu) Leaf Production: Options and Trade‑offs

Non-timber forest products (NTFPs) are known to provide livelihoods for forest-based communities across the world. While ensuring the sustainability of NTFP harvests is a key challenge, optimizing the production of NTFPs through appropriate silvicultural practices is also critical for forest-based economies. In Central India, the suitability of fire or pruning practices for enhancing the production of leaves of the tendu tree (Diospyros melanoxylon) has been much debated. While villagers commonly adopt annual litter fires, the state Forest Department urges leaf collectors to adopt the more labor-intensive practice of pruning. On the other hand, conservationists recommend completely hands-off management (no fire or pruning). In this study, we compared leaf production from the competing practices of litter fire, pruning, pruning-with-fire, and hands-off management, that are experimented with in community-managed forests. We checked for confounding factors such as tree canopy cover, presence of tendu trees, and inherent differences in forest type. We conducted the study during the pre-harvest season from March to May 2020 in villages in the northern Gadchiroli district of Maharashtra, India. We found that pruning and pruning-with-fire lead to higher root sprout production and, in turn, higher leaf production per unit area when compared to litter fire and the control (no pruning or fire). Fire alone led to a negative impact on leaf production. Implementing pruning instead of litter fire, however, comes with labor costs. Its adoption is therefore linked with the institutional arrangements for tendu management and marketing that shape community perception of costs.
