Study finds decline in use of non-timber forest products in forested landscapes of Karnataka, Kerala

The Hindu08-08-2025
Scientists in a new study conducted in eight diverse forested landscapes in the States of Karnataka and Kerala have found that many households noted a decline in non-timber forest products (NTFPs) use over the last decade due to restricted forest access, decline in resource availability, and new livelihood opportunities.
The scientists interviewed 641 households across eight forested landscapes in southwestern India to understand the extraction patterns of NTFPs. 'This study sheds light on the nuances of engagement in such activities, using empirical data from eight diverse forested landscapes in the States of Kerala and Karnataka,' CWS said.
The eight landscapes included Sirsi-Honnavara, Sharavathi, Mookambika, Someshwara, Kudremukh, Brahmagiri, Parambikulam, and Periyar.
According to the Centre for Wildlife Studies (CWS), NTFPs are a critical resource for rural communities in the Global South, supporting the lives of an estimated 2.77 billion people.
The researchers conducted semi-structured interviews with 641 households, and owing to the overlap in extraction for multiple purposes, they classified households along a four-tier scale of extraction engagement: 0 – Not involved in NTFP extraction (38.68%); 1 – Gather only fuelwood and leaf litter (8.73%); 2 – Extract NTFPs only for household/domestic use (24.80%); 3 – Extract at least one species for commercial sale (27.76%).
'Importantly, a large number of households (73.28%) reported that their extraction activity had decreased over the past decade. The most commonly cited reasons included reduced access to forests, decline in resource availability, and improvement in the availability of alternative livelihoods,' CWS said.
Sikha Hariharan from the Centre for Wildlife Studies and Manipal Academy of Higher Education who is the lead author of the study said, 'The region-wide examination of extraction patterns helped us capture regional differences in household-level engagement across multiple landscapes, including previously underrepresented areas in NTFP studies. The reports about declining natural availability of forest resources are concerning and call for long-term ecological studies and monitoring programs to track changes in NTFP availability, extraction rates, and ecological impacts over time.'

A Kerala engineer who wanders with wild elephants

The engineer-turned-environmentalist now works with the Centre for Wildlife Studies, where he manages an elephant project. His job lets him travel, study elephants, and interact with researchers and foresters in the same line of study. 'But my aim is not all these. Well, actually, there is no aim. I am just happy being in the company of elephants. Their calmness makes me feel connected to everything around, and their demeanour is what evokes a serene happiness in me,' Aneesh smiles. 'I have clicked them in the wild and otherwise, and have won about 12 international awards (including Sanctuary Asia, Nature in Focus, a Russian award titled Golden Turtle, the Monochrome Photography Awards, and an Italian competition award called Asferico, etc.) for my clicks. But, if you ask me, they are things that just happened on the way. I just want to be with them. Their calmness made me feel secure even when I was without a job, when I was going through tough times. The bond, actually, is beyond words.'

New study reveals how lion-tailed macaque strategically uses its habitat amidst increasing human pressures

In a new study, the Bengaluru-based Centre for Wildlife Studies (CWS) has shed light on how the endangered and endemic lion-tailed macaque (Macaca silenus) selectively and strategically uses its habitat in response to increasing human pressures. The study titled 'Highs and lows of arboreal life: Space use and movement strategies of lion-tailed macaques (Macaca silenus) in the Western Ghats of India' conducted in the Silent Valley National Park highlights how differences in forest management and human presence can shape animal behavior even within protected areas with similar forest structure. Fewer than 4,000 The lion-tailed macaque is found only in the Western Ghats with fewer than 4,000 individuals remaining and the Silent Valley National Park is a stronghold for its conservation. In the study led by Sikha Hariharan, a Doctoral Fellow at CWS, examined spatial ecology and movement-based habitat selection of two lion-tailed macaque troops living in areas with differing levels of human presence within the boundaries of the park. The CWS scientists tracked two troops of macaques, one in the boundary or buffer zone and another in the core zone of the National Park. They combined GPS tracking, vertical space use assessment, and advanced movement modelling to study how the macaques utilised the space around them, both high in the canopy and across the forest floor, one in the boundary or buffer zone and another in the core zone. The CWS said that the study troop living in the buffer of the protected area maintained a smaller home range and spent nearly all the time (94.2%) in the mid-level forest canopy. 'Their avoidance of the lowest forest strata suggests a strategic response to ecological factors and increased risks from humans, predators, or other disturbance. In contrast, the interior troops showed greater use of the forest floor with large parties descending to the ground and occupied a much larger home range,' the CWS said. Ecological flexibility It added that while both troops spent the majority of their time mid-canopy, the more terrestrial behavior of the core-area, interior forest troop highlights a level of ecological flexibility not previously attributed to this species, which has long been considered strictly arboreal. The macaques also demonstrated consistent patterns in their use of space near key resources such as fruiting trees and dense canopy patches. Ms. Hariharan said that an animal's movement reflects how it perceives its environment and balances food, safety, and survival, and is usually the first visible indicator of any response to changes around them. Understanding risk 'While terrestriality or usage of the ground was only attributed to macaque populations in degraded habitats, our study found that even in the absence of disturbances, the macaques routinely explore and use the forest floor. However, these also have their risks in terms of exposure to threats, so it is essential to prioritize continuous canopy connectivity, and even more critical to incorporate three-dimensional space use in wildlife conservation planning,' Ms. Hariharan said.
