“…The progression from S3 to S5 is associated with increased competition and mortality, which can reduce both R and N (Li et al, 2019). Other factors, such as stand origin, floral and faunal communities, geography and climate, and disturbance may also influence the pattern and quantitative relationships of R and N among life stages (D'Amato et al, 2009;Ostertag et al, 2014;Jin et al, 2019;Ray et al, 2021).…”

“…Many assessments of tree diversity in natural stands use permanent monitoring plots, wherein the recording of trees begins when they reach a diameter at breast height (DBH; 1.3 m) of ≥ 1 cm, following the standards proposed by the Center for Tropical Forest Science (He et al, 1996;2002;Ostertag et al, 2014;Inman-Narahari et al, 2016;Shankar, 2019). Few studies have assessed trees with a DBH < 1 cm (Zhang et al, 2010), because these individuals are often grouped together under "regeneration" and assessed at lower vegetation strata (Barna & Bosela, 2015;Liira et al, 2017;Lin et al, 2017;Awasthi et al, 2020;Ray et al, 2021). However, variability in regeneration may not be well reflected in understory surveys (Clark et al, 1999).…”

Natural forests comprise trees of different species and sizes, constituting a “biotic framework”. Although examinations of diversity patterns at various spatial scales are frequently conducted, life stages are rarely accounted for. Pine-oak mixedwood forest is widely distributed around the world and constitutes main forest type in the Nanpan River Basin in southwest China. We established a fixed plot with an area of 100 m × 100 m in an undisturbed forest stand and classified trees according to five life stages based on their diameter at breast height (DBH) and height. Then, we calculated eight traditional diversity indices for each life stage. We found that species richness (R), abundance (N), and three diversity indices first increased and then decreased with increasing life stage. As sampling area increased, R, the Shannon-Wiener index (H') and Simpson’s diversity index (D) first increased quickly, followed by a reduced rate of increase, whereas N showed a linear increase and three evenness indices showed gradual decreases. Global Moran’s I values for each diversity index were small, indicating weak spatial autocorrelation. Both R and N of shrubs and saplings decreased sharply with life stage, with only large trees comprising the later life stages. Our results indicate that species diversity patterns in pine-oak forests, particularly in early successional stages, differ among life stages. The changes contribute to the understanding and conservation of forest biodiversity.

“…The use of litter fire is considered a low-cost management practice with little labor required to “manage” (burn) large forest areas. Given a large number of fire-tolerant species in Central India, fires have likely been a part of the complex dynamics of these forests (Saha and Howe 2006 ; Ray et al 2020 ). The use of fire, however, is deemed illegal by the Forest Department because it is considered damaging to forests.…”

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

et al. 2023

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. गौण वन उत्पादने जगभरातील वन-आधारित समुदायांसाठी उपजीविका म्हणून महत्त्वाची आहेत. त्यांच्या शाश्वत उपलब्धतेसाठी तसेच त्यांच्यावर अवलंबून आजीविकांच्या दृष्टीने वन उपजाच्या नियोजन पद्धतींचा वनवृक्षशास्त्राच्या दृष्टीने अभ्यास होणे गरजेचे आहे. मध्य भारतातील वन-आधारित समुदाय अनेक वर्ष तेंदू वृक्षाच्या पानांना (म्हणजे बिडी-पत्त्याला) निरनिराळ्या पद्धतीने संकलित करीत आहेत व त्याकरिता निरनिराळ्या पद्धतीने नियोजन करीत आहेत. झाडाची झुडपी वाढ करून, पाने हाता जवळ वाढवणे हा त्यातील मुख्य उद्देश आहे. यामध्ये झाडाच्या रोपांची मुळाशी छाटणी करणे (खुट/बेल कटाई) किंवा, जंगलातील पाचोळा पेटवणे, किंवा या दोन्ही पद्धती एकत्रित वापरणे (‘छाटणी-व-आग’) अशा पद्धतींचा समावेश आहे. अलीकडे काही लोक तेंदू संवर्धनासाठी झाडाची विना-नियोजन वाढ होऊ देतात (म्हणजे विना आग आणि विना खुट कटाईने). यातील कोणत्या पद्धतीने प्रती हेक्टरी सर्वात जास्त तेंदू पाने तयार होतात याचा अभ्यास आम्ही केला. यासाठी आम्ही उत्तर गडचिरोली, महाराष्ट्र येथील काही गावांच्या सामुहिक वन क्षेत्रात मार्च ते मे २०२० मध्ये वेगवेगळ्या नियोजन पद्धतीमध्ये होणाऱ्या तेंदूपत्ता उत्पन्नाचा पद्धतशीर अभ्यास केला. एकूण आम्हाला असे दिसले की, आग वापरण्यापेक्षा तेंदूच्या रोपांची मुळाशी केलेली छाटणी व ‘छाटणी-व-आग’ या पद्धती अधिक पानांचे उत्पन्न देतात. आम्ही पाहिले की स्थानिक जंगल प्रकार, त्याची दाटी, व तेंदू वृक्षाची निकटता या निकषांमुळे पानांच्या उत्पन्नात नियोजन पद्धतीपेक्षा जास्त परिणाम होत नाही. प...

“…The forest biomass and productivity are governed by growth traits and affected by various site factors. Thus, the chronsequence assessment of forest stand would help to predict the vegetation development and dynamics of the species (S. S. Bargali et al, 1992; Long & Turner, 1975; Ray et al, 2020). Litter biomass (forest floor and litterfall) is the key determinant of soil organic matter in the forest and essential component of C and nutrient cycle that affect the growth and development of the vegetation and soil C pool (Cornelissen & Thompson, 1997; Mfilinge et al, 2002).…”

In Kumaun Himalaya, the shrublands dominated by Coriaria nepalensis are present in patches and due to their facilitative nature enhance the restoration of degraded hills.This study deals with the dry matter dynamics of C. nepalensis shrublands. The equation for C. nepalensis was developed to measure the biomass and to understand the dry matter dynamics through compartmental models. Total biomass of tree, shrub and herb varied from 71.66 to 217.40 t ha À1 , 43.65 to 77.55 t ha À1 and 11.11 to 64.55 t ha À1 , respectively. The biomass of herbs was higher during monsoon and lowest during the summer season. Litter fall varied from 1.02-1.70 t ha À1 yr À1 and the highest value of litter fall was recorded during winter (52%) followed by rainy (29%) and summer season (19%). Order of contribution of different components to total litter fall was: foliage (45.32%-50.33%) > twigs (36.80%-42.22%) > miscellaneous litter (4.62%-6.97%) > Bark (3.56%-5.47%) > reproductive parts (2.13%-3.57%). Shrub floor biomass was recorded maximum during the rainy season (11.32-37.55 t ha À1 ) followed by the winter season (13.03-25.36 t ha À1 ) and minimum in the summer season (6.83-12.80 t ha À1 ). Net primary productivity in trees, shrubs and sapling was ranged from 0.94 to 11.01, 1.83 to 4.88 and 0.55 to 0.87, respectively. Due to less canopy cover, the litter fall was less than from the majority of the forest types of the region. Thus, proper conservation and management measures must be designed to improve the structural components and functional traits of the shrubland ecosystem to enhance the ecological services on sustained basis.
