FIFTY YEARS AGO AUGUST 13, 1976 — Kabini project has cut off routes of elephants (From the archives)

What happened (Kabini project and elephant habitat changes reported in 1976)

An ecological reconnaissance account from August 13, 1976 recorded an observation linking the Kabini project and related land changes to elephant habitat shrinkage, fragmentation, and disruption of traditional migration routes. The account focused on elephant forests across several southern regions: Bandipur and Nagarahole in Karnataka, Mudumalai in Tamil Nadu, and Wynaad in Kerala.

According to the historical note, the key drivers mentioned were: the Kabini reservoir and encroachments in vested forest areas such as Pulpully in Kerala. The account states that these changes “drastically shrunk” elephant habitat and “split” habitat into separated patches. It also reports that elephant movement between these forest blocks became disrupted, affecting traditional migration routes.

Background and earlier position (Elephant landscapes across multiple states)

Elephant conservation in peninsular India often depends on connected forest landscapes rather than isolated pockets. The 1976 account explicitly describes cross-border ecological dependence across states—Karnataka, Tamil Nadu, and Kerala—by naming forest regions in each state (Bandipur and Nagarahole; Mudumalai; Wynaad).

Within this connected landscape framing, “migration routes” matter because elephants typically move seasonally or in response to resource availability. A project that creates barriers (for example, a reservoir) and a land-use pattern that reduces forest area (for example, encroachment into forest areas) can reduce the usable space for such movement.
