| Abstract | The Uttara Kannada District, divided into five coastal talukas, each contributing to a rich estuarine landscape. Karwar Taluka, the largest of these, spans an impressive 677.72h, followed by Kumta at 207.19h, Honnavar at 129.57h, Ankola at 79.26h, and the smaller Bhatkal Taluka at 25.91h. This unique geographical composition sets the stage for a critical comparative analysis of its two most prominent mangrove ecosystems, found within the Kali and Aghanashini estuaries. The study reveals a striking contrast in their current status and ecological health. The Kali estuary, for instance, hosts a notable diversity of 14 true mangrove species, including resilient examples such as Avicennia officinalis and Sonneratia caseolaris. However, its mangrove distribution is markedly fragmented, a condition that leaves it vulnerable to natural and anthropogenic pressures. Despite these significant challenges, recent conservation efforts have begun to show promising results, suggesting a potential path to recovery. In contrast, the Aghanashini estuary presents a more pristine and ecologically robust environment. Its status as a free-flowing river has been a key factor in its preservation, leading to its recent and well-deserved designation as a Ramsar Wetland of International Significance. This recognition highlights its unparalleled biodiversity, which includes 12 true mangrove species and an additional 33 mangrove-associated species. The estuary's ecological value extends far beyond its flora; it serves as a critical habitat for a wide array of marine life and supports the livelihoods of over 6,000 local households. Despite its current health and recent international recognition, the Aghanashini is also under threats, particularly from proposed developmental projects and the expansion of commercial aquaculture, which could jeopardize its delicate balance. Ultimately, while both estuaries are crucial to the region's overall ecological integrity, the Aghanashini stands out as a well-preserved wetland in sharp contrast to the fragmented patches of the Kali estuary. |
