Monsoon Croaks Bioblitz 2025: citizen scientists gear up for third season of frog mapping
The programme officially began on Friday, following the India Meteorological Department's declaration of monsoon onset and will continue until October 1.
Over the past two years, this initiative has become a vibrant platform for nature enthusiasts, students, forest watchers, researchers, and the public to actively engage in biodiversity documentation. In 2023 and 2024, over 3,000 amphibian observations were contributed by nearly 400 citizen scientists, recording more than 100 species from various habitats—home gardens, roadsides, paddy fields, wetlands, and forest streams.
Notable species
Some notable species recorded include the purple frog (Nasikabatrachus sahyadrensis), a rare, burrowing species endemic to the Western Ghats; Malabar gliding frog (Rhacophorus malabaricus), known for its ability to leap and glide between trees; Silent Valley bush frog (Raorchestes silentvalley); Kalpetta yellow bush frog (Raorchestes nerostagona; wrinkled frog (Nyctibatrachus spp.); and the stream-dwelling micrixalus frogs with their characteristic foot-flagging behaviour.
All observations are contributed via the iNaturalist platform, allowing participants to submit frog photos and call recordings from any location across the State. These sightings help map the distribution of both common and threatened amphibians, track their breeding patterns, and assess habitat preferences—especially for those found outside protected areas.
'Frogs are important ecological indicators, acting as natural pest controllers and food for many animals. Their presence reflects ecosystem health and freshwater availability,' says Peroth Balakrishnan, Head of the Wildlife Biology Division at KFRI and coordinator of the programme. 'Through Monsoon Croaks, we not only generate critical data, but also build a community of biodiversity ambassadors.'
Ecological research
Verified observations from this initiative are contributed to the Global Biodiversity Information Facility (GBIF), a worldwide open-access biodiversity database. These data are valuable for ecological research, environmental education, conservation planning, and climate change studies.
This year, the KFRI aims to reach more rural communities, school eco-clubs, and nature groups by offering training sessions and frog walk events. A special focus will be on identifying breeding habitats for endemic frogs under threat due to habitat loss, pollution, and climate variability, according to Dr. Balakrishnan.

‘Third-party impact assessment needed for NH projects'
A public convention organised by the Kerala Samsthana Janakeeya Prathirodha Samithi on the condition of the newly constructed national highway across the State called for a third-party impact assessment of major projects such as national highways. T.V. Sajeev, a scientist associated with the Kerala Forest Research Institute (KFRI), who inaugurated the convention, pointed out that an impact assessment study is often carried out by agencies appointed by the contractors in their favour, thereby defeating the purpose of such studies. The convention, held at the Sports Council Hall in Kozhikode on Saturday (July 5), brought together several experts in the fields of environment, construction, and geology to brainstorm solutions to the problems at hand. 'The topography of Kerala cannot support the kind of construction typically carried out in other States, where there is enough vacant space. This State is narrow, densely populated, and extremely sensitive,' said Mr. Sajeev. He alleged that land acquisition and the destruction of large trees had contributed to the recurring outbreaks of Nipah infection in the State. 'Around 75,000 large trees were cut down for the widening of National Highway 66. The bats that lived on these trees had to migrate to the nearest available habitat, often trees in house compounds. The overpopulation of bats in a single tree weakens some of them, making it easier for parasites in them to perform a 'species jump,'' Mr. Sajeev said. He also pointed out that the huge wall constructed in the North-South direction in the form of the National Highway, prevented the free flow of rainwater from the mountains to the sea, though the distance is very short. 'We faced a flood in 2018 before the NH widening. The situation would be worse if we had rain of that intensity once again', he added. Geologist Radhakrishnan Kinattinkara highlighted the characteristics of laterite soil, which absorbs rainwater like a sponge. However, only the upper layer is structurally strong, while the underlying layer is mushy. 'When laterite hills are cut perpendicularly, the mushy layer is exposed. It oozes water and cannot hold on its own, ultimately leading to collapse,' he said. Mr. Radhakrishnan said that the rock formation in Kerala is over 35 million years old and should be treated as geological monuments worthy of preservation. He added that the damage caused by the highway project could have been minimised if it had been constructed on viaducts rather than on embankments. Noted environmentalists and activists, including Sreedhar Radhakrishnan, Joseph C. Mathew, Hashim Chendambilli, N. Subramanian, S. Rajeevan, and N.V. Balakrishnan, participated in the discussions. The convention demanded that the State government appoint an expert committee to conduct a comprehensive study on the condition of the National Highway.

Deadly fungus threatens endangered Western Ghats tree
Scientists have sounded the alarm on a newly detected fungal disease attacking Dipterocarpus bourdillonii, a critically endangered tree endemic to the Western Ghats. The phytopathogen, Corynespora cassiicola, a highly aggressive fungus, is known to infect more than 530 plant species. The findings by Shambhu Kumar (Principal Scientist and Head, Forest Pathology Department, Kerala Forest Research Institute, Peechi), along with Raghvendra Singh (Senior Assistant Professor, Department of Botany, Banaras Hindu University, has been published in June 17th edition of Mycosphere journal. This marks the first recorded instance of the pathogen affecting D. bourdillonii, raising serious conservation concerns. The was identified based on morpho-cultural characteristics and molecular phylogenetic evidence. Detection of the emerging leaf spot and blight disease affecting Dipterocarpus bourdillonii highlight the urgent need for disease surveillance and integrated conservation strategies to protect one of Western Ghat's most vulnerable rainforest trees. 'Dipterocarpus bourdillonii (family: Dipterocarpaceae) is a critically endangered tree species listed on the IUCN Red List. Endemic to the Western Ghats of India, it plays a vital ecological role in maintaining rainforest canopy structure and supporting biodiversity. Economically, its hardwood is valued for construction and furniture, while its oleoresin (wood oil) has traditional medicinal and industrial uses. Due to overexploitation and habitat loss, the species already faces severe threats. The emergence of this additional biotic threat further underscores the urgent need for conservation measures to protect and restore its dwindling population,' Mr. Kumar said. The investigation of Corynespora cassiicola infecting Dipterocarpus bourdillonii in Kerala using morpho-molecular tools is of significant importance. Molecular identification ensures accurate pathogen detection, overcoming the limitations of morphology-based methods, and facilitates early diagnosis and monitoring. This study is crucial for understanding the disease's epidemiology, guiding effective disease management strategies, and safeguarding this threatened species. Additionally, it contributes to forest health surveillance and supports both ex-situ and in-situ conservation efforts, Mr. Kumar pointed out. Corynespora cassiicola is a widespread phytopathogen causing leaf spots, target spots, and blight diseases in a wide range of plant species, including economically important crops such as rubber, soybean, tomato, cucumber, cotton, as well as medicinal and ornamental plants. It thrives in warm, humid climates and spreads through conidia (spores produced by fungi) via wind, water, and human activity. The pathogen impairs photosynthesis, leading to defoliation, reduced yield, and plant death in severe cases. Management of the pathogen involves the use of resistant cultivars, cultural practices (e.g., proper spacing and removal of infected parts), and fungicides such as mancozeb and azoxystrobin. Early detection and integrated disease management are vital to minimising its impact and preventing outbreaks, noted Mr. Kumar.

With a population of 250, Western Ghats tree species faces fungal threat
Kochi: Kerala Forest Research Institute identified a fungal infection in Dipterocarpus bourdillonii, known as Chiratta-anjili, Kalpayin and Karanjili, a plant species already in the critically endangered category of the IUCN Red List. Endemic to the Western Ghats, there are around 250 mature individual trees of this species, found in Kerala, Tamil Nadu and Karnataka, as last assessed in 2020. Most of them are seen in the wild in Kerala. Posing a threat to the survival of this species, the infection was found in the leaves, which will affect the productivity of the trees. Dr Shambhu Kumar, principal scientist and head of the forest pathology department at KFRI, along with Dr Raghvendra Singh, senior assistant professor in the department of botany at Banaras Hindu University, detected an emerging leaf spot and blight disease affecting the Karanjili. The disease-causing pathogen (phytopathogen) was identified as Corynespora cassiicola based on morpho-cultural characteristics and molecular phylogenetic evidence. Dr Kumar stated that the fungal infection on the leaves will affect the photosynthetic capacity and its ability to produce energy, thereby adversely affecting the health of the tree.

The emergence of this additional biotic threat further underscores the urgent need for conservation measures to protect and restore its dwindling population," Dr Kumar said. Dr P A Jose, a former scientist at KFRI who studied this species earlier, said this needs extreme care; otherwise, it will lead to extinction. "The main reason for the species falling into the critically endangered category is its very low natural regeneration capacity because of a non-viable embryo. Prior to the British regime, this species did not require conservation priority as there was a good number of populations. It was harvested for the softwood industry and habitat degeneration also led to the declining population," Dr Jose said. Aralam Wildlife Sanctuary has a good number of existing populations. It is an evergreen population species.
