Dandeli forest, situated in the Uttara Kannada district of Karnataka, is a part of the globally recognized Western Ghats biodiversity hotspot. Famous for its diverse range of flora and fauna, this forest stands as an essential wildlife habitat. The Kali Tiger Reserve, neighbouring Dandeli Forest, consists of two significant protected areas in the region – the Dandeli Wildlife Sanctuary and the Anshi National Park.
Potential Threats to the Dandeli Forest Ecosystem
Like many other natural habitats, Dandeli Forest faces significant environmental disturbances due to various reasons. These include changes in climate patterns, invasive species, historical shifts, and human interventions.
Impact of Climate Change on Dandeli Forest
Changing climate patterns have caused substantial effects on the forest ecosystem of Dandeli. Altered rainfall patterns coupled with rising temperatures have led to ecosystem changes and a decrease in grasses over recent years.
The Invasion of Eupatorium Weed
The invasive eupatorium weed poses another major environmental challenge. This weed species replaces native grasses, negatively affecting herbivores as it’s not their preferred food source. Moreover, it’s highly susceptible to fires, which increases the risk of forest fires.
Historical Changes: Colonial-era Influences
Historical changes like forest transformations during the colonial era have affected the character of Dandeli forest, transforming it from semi-evergreen to moist deciduous forests.
Forest Fires and Their Environmental Impact
During the British era, controlled fires, also known as Slash and Burn, were suppressed. Coupled with the introduction of the non-native eupatorium weed, this has led to uncontrolled forest fires, severely impacting the forest ecosystem.
Effects on Herbivores and Predators
The decrease in grasses due to climate change and invasive weeds has impacted the herbivore population. This shift influences the prey base for predators like leopards and tigers, leading to an increase in conflicts with humans and predation on local cattle.
Need for Sustainable Conservation Efforts
Addressing these environmental challenges calls for urgent and sustainable conservation efforts. It’s crucial to formulate adaptive strategies to lessen the impacts of climate change on ecosystems and communities that rely on them.
Related UPSC Exam Questions
Several previous year questions from the UPSC Civil Services Examination relate to the ecological importance of such forest reserves. For instance, a 2017 prelims question asked, “From the ecological point of view, which one of the following assumes importance in being a good link between the Eastern Ghats and the Western Ghats?” The answer was the Sathyamangalam Tiger Reserve. Another 2015 question related to varying climates in national parks, and a 2020 question focused on protected areas located in the Cauvery basin. These questions highlight the importance of understanding our forest ecosystems’ ecological aspects.
